Understanding MICA Cargo: Major Imported Goods, Former Tariff Items, and Cargo Insurance Practices

What Are MICA Cargoes?

MICA cargoes refer to a practical categorization of cargo groups that were organized as major import cargoes in traditional ocean cargo insurance practices.

The abbreviation MICA relates to Major Import Cargo, and in older documents and operational materials, variations of the term appear, such as Major Import Cargo Tariff Agreement or Major Import Cargo Agreement Tariff.

Therefore, in this article, MICA is treated not as a fixed formal English term but as a former practical designation related to major import cargo tariffs or major import cargo in traditional practice.

The core of MICA cargoes consisted of raw materials and primary products that had high import volume at the time and required cargo-specific organization of accident trends, transportation methods, vessel conditions, and insurance terms.

Typical examples include coal, fertilizer, grains, iron ore, manganese ore, petroleum products, cotton, rice, salt, soybeans, sugar, and wool.

This article does not indicate current tariff rates, surcharge rates, or underwriting conditions. It provides an overview of the concept of major import cargoes and former tariff items in traditional ocean cargo insurance practice as historical background.

In current ocean cargo marine insurance, specific tariff rates and underwriting conditions are determined individually by insurers based on factors such as the insurance company, insurance contract, cargo details, trade route, transportation method, vessel conditions, storage conditions, and loss history.

This article does not treat MICA cargo as a current rate table standard or as an automatic underwriting criterion.

Through the background of traditional practice, it organizes the important ongoing risk assessment concept of “viewing risks by combining cargo type, packaging, vessel conditions, stowage form, route, storage, and accident trends.”

The Historical Positioning of MICA Cargo

MICA cargo is a practical classification used in marine cargo insurance for foreign trade, targeting major imported raw materials and primary products with large import volumes. These cargoes require detailed organization by cargo type due to their accident trends and modes of transportation.

These cargoes have different forms of packaging and transportation methods depending on the commodity, such as bulk cargo, tanker transport, conventional vessels, bagged goods transport, and tank transport.

Furthermore, factors beyond the cargo’s nature—such as vessel age, classification society, vessel type, cargo hold or tank design, piping, cargo handling equipment, stowage methods, and storage conditions—can influence the frequency and scale of damages.

Therefore, the concept of MICA cargo was used as a practical framework to categorize key cargoes, enabling confirmation of each cargo's hazard characteristics, vessel conditions, and transportation conditions.

Precautions When Handling the Abbreviation MICA

Regarding MICA, the expanded English names may vary depending on old documents, glossaries, internal materials, or practical customs.

Example Notation	Understanding in Japanese	Usage in This Article	Points to Confirm
Major Import Cargo	主要輸入貨物	Used to describe the group of goods called MICA cargo.	Does not necessarily mean the tariff agreement itself.
Major Import Cargo Tariff Agreement	主要輸入貨物料率協定	Handled as an example of notation related to old tariffs or agreed rates.	Confirm the document’s creation date and official title.
Major Import Cargo Agreement Tariff	主要輸入貨物協定料率	Considered one of the expansions found in older documents.	Confirm on a case-by-case basis whether it refers to the same system as other notations.
MICA Tariff	MICA料率・主要輸入貨物料率	Used as a practical term referring to traditional tariffs or rate tables.	Distinguish from current rate tables.
MICA Cargo	MICA貨物	Used as a designation for the relevant cargo group.	Does not directly indicate the current underwriting classification.

Therefore, when explaining the meaning of the abbreviation MICA, it is safer not to assert a single English expansion as an absolute official name.

When referring to old documents, confirm the title, issuing entity, applicable cargo, validity period, and conditions described in those materials.

Differences Between the Old Tariff Era Approach and Current Practice

Item	Old Tariff Era Approach	Current Practice	Points to Note for Verification
Rates and Conditions	Standard rates and conditions were referenced according to cargo classification and transportation conditions.	Determined individually based on the insurer, contract terms, claims history, route, and vessel conditions.	Do not directly apply old rates to current quotations.
Cargo Classification	There was a practical approach to categorize major imported cargoes into certain groups.	Confirm cargo nature, packaging, transportation method, quality standards, and storage conditions individually.	The risk is not necessarily the same even for identical cargo names.
Vessel Conditions	Age, class, type, and stowage pattern of the vessel were organized as important factors.	Verify vessel name, IMO number, Class Status, vessel changes, and transshipment.	The presence of a classification alone does not guarantee compliance with all conditions.
Accident Trends	Typical damage causes and accident trends were organized by cargo type.	Determine actual accident causes based on survey, evidence, and chronology.	Do not conclude individual accident causes based solely on past general trends.
Practical Reference Value	Used as practical reference material for rate setting and condition organization.	Serves as a historical and analytical viewpoint for assessing cargo risk.	Confirm current contract terms separately.
Underwriting Judgment	There were cases where underwriting was organized based on cargo classification and standard conditions.	Comprehensive judgment based on cargo, route, vessel, packaging, claims history, and management system.	Acceptance cannot be determined solely by being classified as MICA cargo.

The term MICA cargo does not directly indicate current insurance rates.

However, it remains a useful historical concept for understanding the practical sense of checking accident trends, transportation methods, and vessel conditions by cargo type.

Relationship with Deregulation of Non-Life Insurance Premium Rates

In Japan's insurance system, the Insurance Business Act was fully revised and came into force on April 1, 1996.

Subsequently, with the amendment of the Act on the Rate Calculation Organizations of Non-Life Insurance in July 1998, the obligation to use rates calculated by the Non-Life Insurance Rating Organization and the Automobile Insurance Rating Organization was abolished. The system transitioned to one utilizing reference net rates and standard rates.

Against the backdrop of these reforms, deregulation of non-life insurance products and premium rates advanced, expanding practical operations where each insurance company determines rates and conditions according to contract details and risk.

However, it is not possible to conclusively state that all MICA-related rate tables, agreements, or practical applications ended on the same date solely based on the overall timing of these system reforms.

When confirming the specific application period, revision timing, or abolition timing of MICA, it is necessary to review the official rate tables, agreement documents, insurance company materials, or industry publications from that time.

What Are Old Tariff Goods?

Old tariff goods refer to a practical category of cargoes for which, historically, standardized rates and conditions were organized according to the type of cargo, transport method, route, or vessel conditions.

MICA cargo can be understood as one of the representative groups within this category.

The term "tariff" here does not refer to current insurance premium rates.

In traditional marine cargo insurance practices for foreign trade, it was a historic framework of rates and conditions used to classify cargo characteristics, packaging, transport modes, routes, vessel conditions, and accident patterns.

Main Cargo Included in MICA Cargo

Example Cargo	Main Transport Mode	Accident Trends / Points of Caution	Current Practical Confirmation Points
Coal	Bulk carrier, bulk shipment	Spontaneous heating, ignition, moisture content, gas generation, and holds management including stowage conditions may be problematic.	Check cargo properties, temperature, moisture, stowage method, vessel age, classification, and ventilation conditions.
Grains, Soybeans, Rice	Bulk carrier, bagged cargo, container, conventional vessel	Water damage, mold, heating, pest infestation, quality deterioration, odor, and ventilation control are concerns.	Verify moisture content, quality certificates, fumigation, storage conditions, transport duration, quarantine, and hold condition.
Iron Ore, Manganese Ore	Bulk carrier, bulk shipment	Quantity discrepancies, powdering, moisture content, liquefaction risk, hold condition, and hull loading issues may arise.	Confirm quantity inspection, moisture content rate, permissible moisture under transport regulations, vessel type, vessel age, and stowage conditions.
Oils	Tanker, tank, bulk liquid transport	Contamination, water ingress, residue from prior cargo, insufficient tank cleaning, and quantity discrepancies are common issues.	Check previous cargo, tank cleaning, piping, sampling, quality standards, and vessel and tank conditions.
Fertilizers	Bulk carrier, bagged cargo, conventional vessel	Water damage, caking, deterioration, packaging damage, foreign material contamination, and corrosiveness are concerns.	Confirm cargo packaging, moisture control, hold condition, storage conditions, quality standards, and segregation from other cargoes.
Sugar, Salt	Bulk, bagged cargo, conventional vessel, container	Water damage, caking, dissolution, contamination, foreign material contamination, and packaging damage are common problems.	Verify packaging, moisture countermeasures, hold condition, storage conditions, cargo handling methods, and quantity records.
Cotton, Wool	Bales, conventional vessel, container	Water damage, fire, heating, contamination, compressed packaging damage, and odor transfer may occur.	Check packing condition, storage location, fire risk, moisture content, and risks of odor or contamination.
Raw Oil, Liquid Raw Materials	Tanker, chemical tanker, shore tanks	Off-specification, mixing of prior cargo, residual piping content, shore tank contamination, and sample discrepancies are issues.	Confirm pre- and post-loading samples, tank history, piping system, cargo handling records, and inspection certificates.

Even cargoes previously included under MICA cargo are not uniformly subject to current insurance clauses or underwriting decisions.

Presently, judgments are made based on individual cargo details, quality standards, quantity, packaging, transport sections, vessel conditions, storage conditions, and damage history.

Situations Where the MICA Cargo Perspective Remains Useful Today

It is not possible to directly apply the old MICA cargo rating or previous conditions to current contracts.

However, the analytical approach of combining cargo types with transport conditions to assess risks remains valuable for modern marine cargo insurance, transport planning, and accident investigation.

Situation	MICA Cargo Perspective	Current Items to Confirm	Practical Usage
Insurance arrangement for bulk cargo	Considering not only the cargo name but also the hold, vessel type, vessel age, class, and stowage method.	Cargo characteristics, moisture content, vessel name, IMO number, Class status, stowage plan	Organize risk information necessary for underwriting inquiries.
Quality risk confirmation for grain and agricultural products	Confirming moisture, heat generation, mold, pest damage, ventilation, and transport duration as cargo characteristics.	Quality certificates, moisture values, fumigation, storage conditions, transport period	Used as reference to distinguish between external accidents and natural deterioration.
Bulk ore and coal break-bulk transport	Assessing cargo properties alongside the load on the hull and holds.	Moisture content, liquefaction risk, stowage, vessel age, class, and vessel type	Reflect both vessel conditions and cargo risks in underwriting inquiries.
Contamination prevention for bulk liquid cargo	Confirm cargo, previous cargo, tank, piping, cleaning, and samples as a comprehensive set of conditions.	Previous cargo history, cleaning records, wall wash test, samples, piping system	Used for contamination prevention and identifying the cause section after an incident.
Reconfirmation after vessel substitution	Reexamining not only cargo conditions but also the conditions of the replacement vessel.	Vessel name, IMO number, vessel age, class, vessel type, and route	Connects to checking the Institute Classification Clause and vessel age surcharge.
Conventional vessels and heavy cargo transport	Combining cargo, packaging type, vessel type, cargo handling method, stowage, and securing.	Lifting method, securing, deck stowage, class, route, and port operations	Organize both insurance conditions and transport operation conditions.
Initial investigation after an accident	Extracting documents and equipment to confirm based on typical accident trends for the cargo.	Accident timeline, cargo photos, vessel equipment, cargo handling records, storage records	Use the old classification to select investigation items rather than to pinpoint causes.
Practical training for junior staff	Systematically organizing the relationship between different accident trends by cargo and vessel or cargo handling conditions.	Current clauses, actual accident cases, vessel information, and quality data	Used as a thinking framework to assess risk rather than memorizing old rates.

When using the MICA cargo perspective today, it should be applied as an analytical framework to extract cargo-specific risk characteristics and items to check, rather than reusing the old rating.

Situations Where the MICA Cargo Classification Cannot Be Used as the Current Standard

Situation	Reason It Cannot Be Used	Matters to Confirm Instead	Practical Response
When calculating current premium rates	The old tariff is not the rate table for current individual contracts.	Current quotations, cargo details, shipping route, loss history, and insurance terms	Request quotations from the insurance company or specialist insurance agent.
When determining the current scope of coverage	MICA classification alone does not allow confirmation of ICC clauses, special clauses, and exclusions.	Insurance policy, applicable clauses, special conditions, and deductible amount	Confirm the official insurance terms.
When deciding whether insurance claims are payable	Cargo classification alone cannot determine cause of loss, causation, or exclusions.	Cause of loss, damage status, survey, supporting documents, and policy clauses	Notify the insurance company for each individual claim.
When classifying all bulk chemical cargo	Not all bulk chemical cargo necessarily falls under MICA cargo.	Cargo name, chemical properties, specifications, previous cargo, tanks, and transportation conditions	Conduct individual risk assessments for each cargo.
When evaluating vessel eligibility	MICA cargo status alone does not determine classification society, vessel age conditions.	Vessel name, IMO number, class, Class Status, vessel age, and type	Check the Institute Classification Clause.
When concluding continuation by Held Covered	Held Covered does not imply unconditional continuation of coverage.	Notification timing, additional premium, changed conditions, and insurer agreement	Notify as soon as the possibility of conditions outside coverage is identified.
When assessing freight forwarder’s liability	The old cargo classification does not determine contractual status or negligence.	Transport contract, B/L, scope of services, information provided, and limitation of liability	Separate management of insurance claims and liability assessment.

Differences between MICA Cargo, Institute Classification Clause, and Held Covered

Comparison Item	MICA Cargo	Institute Classification Clause	Held Covered
Basic Positioning	This is a traditional practical classification and historical framework that organizes major imported cargo by cargo type.	This insurance clause confirms the class, vessel age, structure, vessel type, and propulsion capacity of the vessel used.	This clause-based concept confirms the continuation of coverage on the premise of notification and condition negotiation when facts outside the terms occur.
Main Subject	Major imported cargo such as coal, grain, ore, oil, etc., and the transport risks related to them.	The actual vessel that carries the cargo.	Facts where vessel conditions, route, or transport conditions deviate from the original terms.
Main Judgment Focus	Organizes cargo types, packaging, vessel conditions, stowage methods, and accident trends.	Determines whether the vessel meets the eligibility requirements under the clause.	Confirms timing of notification, additional premiums, amended terms, and insurer’s consent.
Relation to Current Premium Rates	The old rate tables do not directly indicate current premium rates.	Additional premiums may become an issue depending on vessel conditions.	Additional premiums may be required in response to risks outside the original terms.
Typical Reference Materials	Old rate tables, cargo details, quality standards, packaging, accident data	Policy, vessel name, IMO number, class society, class status, vessel age	Policy, notification records, amended terms, agreed records of additional premiums
Meaning When Changing Vessel	Risk is reassessed by combining cargo type and vessel conditions after the change.	It is reconfirmed whether the replaced vessel meets the eligibility criteria.	Notification and consultation take place as soon as the possibility of deviation from terms is identified.
Meaning After an Incident	Useful as a reference for selecting investigation targets but does not determine the cause of the incident.	Separation of vessel eligibility and incident cause is confirmed.	Notification obligation, term amendments, and continuation of coverage become key issues.
Common Misunderstandings	The misconception that MICA cargo always corresponds to current premium rates.	The misconception that vessel age or other conditions do not matter if the vessel has a class certificate.	The misconception that Held Covered guarantees unconditional coverage.

MICA cargo is a historical framework for cargo classification and risk organization, whereas the Institute Classification Clause and Held Covered are issues related to actual insurance clauses and conditions attached to insurance contracts.

The applicability to MICA cargo alone cannot determine vessel eligibility, continuation of coverage under Held Covered, additional premiums, or claim payments.

Relationship with Vessel Conditions

In practical handling of MICA cargo, not only the type of cargo but also the conditions of the vessel used were important factors.

Specifically, vessel age, classification society, vessel type, structure, tonnage, route, and stowage method impact risk assessment in marine cargo insurance.

For bulk cargoes such as minerals, oil products, ores, grains, and fertilizers, the cargo comes into direct contact with the ship’s holds, tanks, piping, pumps, or cargo handling equipment, making the condition of the vessel’s equipment more likely to link to cargo damage.

Traditionally, practical operations emphasized assessing risk by combining cargo type with vessel conditions.

This fundamental perspective remains useful in current individual underwriting practice.

Relationship with Age Surcharge

In the practical handling of MICA cargo and former tariff items, the age surcharge was also an important point to verify.

The age surcharge system involves applying an additional premium or special conditions on top of the standard insurance premium when loading cargo on vessels that exceed a certain age threshold.

For older vessels, deterioration of the hull, holds, tanks, piping, pumps, valves, and cargo handling equipment may contribute to cargo damage risks.

However, simply using an older vessel does not automatically result in the same surcharge rate being applied.

The age surcharge should be confirmed on a case-by-case basis considering the vessel type, classification society, Class Status, cargo, trade route, stowage method, and the insurance contract terms.

Relationship with the Institute Classification Clause

Understanding the historical background of MICA cargo also requires consideration of its relationship with the Institute Classification Clause.

The Institute Classification Clause is a clause that verifies whether the vessel in use meets specific conditions regarding classification society, vessel age, structure, and propulsion capability.

If the vessel does not meet the prescribed classification or age requirements, it may be necessary to notify the insurer, pay additional premiums, modify deductibles, impose coverage limitations, or confirm acceptance.

The combination of cargo classification and vessel conditions emphasized in traditional MICA cargo practice still influences the current practical approach of verifying vessel name, IMO number, vessel age, classification society, vessel type, vessel changes, and transshipment.

Relation to Held Covered

Held Covered is a concept that confirms the continuation of insurance coverage on the condition that the insurer is promptly notified if certain out-of-condition circumstances occur, and that the necessary additional premium payment or amendments to the terms are agreed upon.

For example, if the vessel on which the cargo is loaded does not meet the initially expected class or age requirements, or if the ship after a vessel change does not meet the standards, notification and consultation under Held Covered conditions may become an issue.

Having Held Covered does not mean that coverage is automatically provided unconditionally for any out-of-condition transportation.

The timing of notification, any additional premium, changes in conditions, nature of the cargo, route, vessel conditions, and the insurer’s consent all need to be confirmed.

Relationship with Bulk Chemical Cargo

Not all bulk chemical cargo qualifies as MICA cargo.

However, the concept observed in MICA cargo and former tariff items—evaluating risk by combining the cargo type and transport conditions—is also useful for understanding bulk chemical cargo.

For bulk chemical cargo, factors such as the chemical properties of the cargo, quality standards, tanks, previous cargo, cleaning, piping, vessel age, class, sampling, and cargo handling methods significantly affect damage assessment.

Rather than judging solely by the cargo name, there is a commonality with MICA cargo risk assessment in confirming the cargo’s nature alongside actual transportation equipment and operational conditions.

Relationship with Conventional Vessel Practices

The concepts of MICA cargo and former tariff items are also related to conventional vessel practices.

In conventional vessel transport, the type of cargo, packaging, handling methods, stowage aboard the ship, port operations, and storage methods greatly affect the pattern of incidents and cost structure.

Both the former tariff items for marine cargo insurance and the classification by item and operation in conventional vessel cargo handling share the approach of confirming risks, operational details, and costs specific to each type of cargo.

However, marine cargo insurance premium rates and port handling charges each follow distinct contracts and pricing systems. They cannot be treated as the same tariff.

Relation to Contamination Incidents

Contamination incidents are a significant concern for bulk cargo and liquid cargo.

In cases involving oils, liquid raw materials, chemicals, etc., cargo may fall outside quality standards due to previous cargo residue, inadequate tank cleaning, pipe residue, contamination of onshore tanks, moisture ingress, or mixing with other cargoes.

In such incidents, a comprehensive review is conducted considering not only the nature of the cargo itself but also the vessel used, tank facilities, vessel age, classification society, previous cargo, cleaning methods, cargo handling equipment, and sampling results.

The concept of MICA cargo and former tariff goods provides a useful perspective in bulk and liquid cargo incident handling, combining cargo classification with transport conditions.

Specific Example 1: Applying Old Tariff Rates for Grain Transport Directly to Current Rates

When arranging insurance for imported soybeans, imagine that the person in charge finds the MICA cargo rates listed in old reference materials and assumes those numbers can be used as the current insurance rates.

However, current transport may differ from the time the old materials were produced in terms of route, containerized transport, inner bag packaging, and temperature and humidity control conditions.

In addition, current blanket contracts may have their own deductibles, quality damage clauses, mold damage provisions, or storage conditions.

In this case, the old materials should be used as a reference to confirm that soybeans are cargo requiring attention to moisture, heat generation, mold, pests, and quality deterioration.

Meanwhile, the current rates and coverage conditions should be verified by presenting to the insurance company detailed cargo descriptions, quality, moisture content, packaging, route, transport duration, vessel conditions, and loss history.

The old MICA rates should not be used as current quotations but rather as historical materials to identify cargo risks that still need checking today.

Example 2: Use in Contamination Investigation of Bulk Liquid Cargo

Assume that bulk liquid raw materials are transported by chemical tanker, and non-compliance with quality standards is discovered at the discharge port.

When looking only at the cargo name, there may be debate as to whether the cargo was included in the former MICA cargo classification.

However, what is important in accident handling is not the mere applicability to the former classification.

It is necessary to check the previous cargo, tank cleaning records, Wall Wash Test results, pre-shipment samples, post-shipment samples, piping systems, onshore tanks, cargo handling sequence, and sample storage conditions.

The MICA cargo perspective is useful for verifying the combination of the cargo's nature together with the vessel, tanks, and cargo handling equipment.

However, eligibility for insurance claim payment should be determined individually based on the applied clause, cause of the incident, external contamination, the inherent nature of the cargo, and supporting evidence.

The MICA classification is not intended to determine the cause of the incident but is used to comprehensively organize the cargo, equipment, and operational conditions that need to be checked.

Example 3: When Loaded on an Older Vessel after Vessel Change

Consider a case where coal is imported by bulk carrier, and at the time of booking, a vessel meeting the age and classification requirements was scheduled.

Subsequently, due to a vessel change, the actual carrying vessel was switched to an older vessel.

If the person in charge assumes that "coal is a traditional MICA cargo and is automatically insured under a blanket contract," and fails to notify the insurance company of the vessel change, issues regarding vessel age conditions and notification obligations may arise after an incident.

In this case, the fact that it is MICA cargo and whether the changed vessel meets the conditions under the Institute Classification Clause are separate matters.

The updated vessel name, IMO number, year built, vessel age, classification, Class Status, and vessel type should be confirmed, and if there is a possibility that these fall outside the conditions, the insurance company must be notified.

If there is a Held Covered clause, confirmation should also be made regarding any additional premium or agreement to amended terms.

Being MICA cargo does not exempt the need to verify vessel age and classification conditions or to promptly notify changes.

Common Practical Issues

Case	Main Issue	Reference Documents	Key Points for Judgment	Initial Response
Using old MICA rates for current quotations	Confusion between old and current rates	Old rate tables, current quotations, insurance contracts	Have the application periods and current conditions been distinguished?	Request a re-quotation based on current conditions.
Assuming the same conditions if the cargo is MICA	Differences in packaging, route, vessel, and loss history	Cargo details, transport plans, loss history	Have conditions other than cargo name been verified?	Organize risk information by individual case.
Change to an older vessel	Age-related surcharges, notification, and Held Covered	Change notice, IMO number, classification information	Has the vessel after change been re-verified?	Notify the insurance company promptly.
Non-standard condition occurs with bulk liquids	Previous cargo, cleaning, piping, and sampling	Cleaning records, samples, analysis results	Can the contaminated section be identified with evidence?	Preserve samples and work records.
Mold and spoilage occur in grain cargo	Moisture, ventilation, delays, and cargo-specific traits	Quality certificates, temperature and humidity data, voyage records	Can external incidents be distinguished from natural deterioration?	Record condition on arrival and time sequence.
Quantity discrepancies occur in ore shipments	Measurement methods, moisture content, loading/unloading loss	Draft Survey, weight certificates, cargo handling records	Are comparisons made using the same measurement standards?	Collect loading and discharge documentation.
Official MICA name varies across documents	Abbreviation explanations and document identity	Original documents, titles, issuing entities, issuance dates	Are assumptions made that the same system applies based solely on name?	Prioritize definitions from original documents.
Claiming compensation based only on old documents after an incident	Current clauses, insurance terms, and cause of incident	Insurance policies, special clauses, accident reports	Is there a basis in the current contract?	Organize applicable clauses and incident causes.

Standard Five Classifications of Freight Forwarder Involvement

The five classifications used in this article are not established by law or industry-wide agreement. They serve as an analytical framework to organize the scope of freight forwarder involvement in this series.

Standard Five Classifications	Main Involvement with MICA Cargo	Focus of Liability Determination	Main Reference Documents
Simple Intermediary	Acts as an intermediary for cargo and vessel information among the shipper, shipping line, insurance company, and insurance agent.	Whether the old tariff or current insurance terms are guaranteed or if involvement is limited to simple information relay	Quotation, emails, guidance documents, intermediary records
Cargo Transportation Service Provider	Provides vessel space booking, transport methods, vessel selection, transshipment, and transport information management.	Vessel information confirmation, notification of vessel changes, selection of transport methods, and subcontractor management	Transport contracts, booking confirmations, vessel notices, operation records
NVOCC / House B/L Issuer	Issues House B/L and undertakes international transport as the contracting carrier.	Actual loading vessel, liability segments, vessel changes, notifications, and limitation of liability	House B/L, Master B/L, booking records, transshipment documentation
Door-to-Door Single Contractor	Responsibly handles collection, ocean transport, transshipment, warehousing, customs clearance, and delivery as a single contractor.	Transport conditions for all segments, vessel and storage management, subcontract management, and explanations to the shipper	Comprehensive quotations, specifications, subcontract contracts, transport plans
Agent/Coordinator for Specific Operations	Individually coordinates insurance arrangements, class inspections, sampling, tank inspections, or accident responses.	Scope of mandate, confirmation duties, authority to notify, arrangement deadlines, and final decision authority	Mandate records, insurance requests, inspection requests, approval records

Contracting Carrier and Actual Carrier are concepts denoting legal or contractual statuses and do not replace the standard five classifications in this article.

Individual tasks such as vessel information searches, class inspections, sampling, tank cleaning confirmation, or inquiries to insurance companies do not constitute a separate sixth classification by themselves.

Decision Flow for Referencing MICA Cargo in Current Practice

1. Confirm the name, issuing entity, and publication date of the MICA or former tariff reference materials to be used.
2. Check the MICA definitions, English terminology, and applicable cargo described in the materials.
3. Clarify that the materials are historical data and not part of current tariff schedules.
4. Verify the official name, type, quality standard, quantity, and value of the cargo in question.
5. Confirm the cargo packaging type: bulk, bagged, tank, container, or bale.
6. Organize cargo-specific risks such as moisture, self-heating, fire, contamination, solidification, or quantity discrepancies.
7. Review loading port, discharge port, route, transit time, transshipment, and storage segments.
8. Check vessel name, IMO number, vessel type, vessel age, classification society, and Class Status.
9. Confirm whether any vessel changes, feeder vessels, barges, or local vessels are involved.
10. For bulk liquid cargo, verify previous cargo carried, tank cleaning, piping, and sampling conditions.
11. Review current insurance policy, open cover arrangements, ICC clauses, special clauses, and deductible amounts.
12. If there is a possibility of non-standard vessels or transportation conditions, confirm Held Covered and prompt notification clauses.
13. Delineate risk items extracted from historical materials separately from the actual current transport conditions.
14. Verify current tariff rates, additional premiums, coverage scope, and underwriting acceptability with the insurance company.
15. In case of an incident, handle it based on current clauses, cause of the incident, evidence, and the contractual positions of involved parties, not based on former classifications.

Common Misunderstandings

Misunderstanding	Actual Perspective	Practical Handling
MICA cargo is still the direct basis for current rate standards.	It serves as a reference from the traditional practical background but does not directly indicate current rates.	Confirm current conditions individually with the insurance company or specialized insurance agent.
Current insurance conditions are determined solely by the old tariff.	Currently, decisions are based on cargo, route, vessel, damage history, and policy terms.	Do not judge premiums or coverage scope based on old documents alone.
All insurance conditions are identical for MICA cargo.	Conditions vary depending on packaging, quality, route, vessel, storage, and damage history, even for the same cargo.	Check cargo details and transportation conditions on a case-by-case basis.
MICA has only one official name.	Multiple English variants appear in old documents and references.	Verify the title and definition in the original source.
Vessel age surcharges are from the old system and no longer relevant.	Even today, vessels with high age or unknown class status may affect underwriting decisions.	Confirm vessel name, IMO number, age, classification, and class status.
If Held Covered is indicated, coverage applies unconditionally even outside policy terms.	Prompt notification, additional premium, and agreement to changed conditions may be required.	Notify as soon as the possibility of out-of-coverage conditions is identified.
Bulk cargo insurance decisions can be made by cargo name alone.	Vessel, previous cargo, tank conditions, handling, storage, and quality standards are also important.	Confirm a combination of cargo characteristics and transportation conditions.
MICA cargo is always automatically covered under blanket policies.	Blanket policies may have exclusions based on cargo type, vessel conditions, and individual declaration requirements.	Check the formal terms of the blanket policy.
Past accident trends under the old tariff prove the cause of individual incidents.	General trends alone cannot establish the cause of individual accidents.	Determine based on survey reports, timelines, and supporting evidence.
All bulk chemical cargo are classified as MICA cargo.	These are not the same classification.	Check cargo name, scope in old references, and current terms.
Whether cargo is MICA determines the freight forwarder’s responsibility.	The forwarder’s liability depends on contractual status, scope of work, and negligence.	Review the Standard Five Classifications, transport contracts, and communication records.
All MICA-related practices ended simultaneously with the 1998 deregulation.	The timing of deregulation and the termination of individual documents or agreements must be checked separately.	Confirm records of revisions and abolishment of applicable old documents.

Practical Points to Note

• MICA cargo does not directly indicate current premium rates or underwriting conditions.
• For the English rendering of MICA, prioritize the titles and definitions found in the referenced historical materials.
• Do not apply historical tariff tables directly to current insurance quotations.
• Use historical materials as reference resources to identify typical risks associated with each cargo type.
• Verify not only the cargo name but also the variety, quality standards, packaging, quantity, and value.
• Confirm the vessel name, IMO number, vessel age, classification society, class status, and vessel type.
• Check the actual vessel loaded after any vessel changes or transshipment.
• For bulk liquid cargoes, verify the previous cargo, tank cleaning, piping, and sampling procedures.
• If there is any possibility of conditions being outside coverage, do not interpret Held Covered as unconditional continuation of coverage; promptly notify.
• In the event of a loss, assessments should be based on the current clauses, cause of the incident, and evidence—not on the MICA classification.

When to Consult a Maritime Lawyer or Specialist

• When there are discrepancies among parties regarding the applicable period for the old MICA documents or rate tables
• When it is claimed that old tariff materials apply to the current insurance contract
• When disputes arise over current premium rates or underwriting conditions
• When the timing of the Held Covered notice or agreement to additional conditions becomes an issue
• When there are disputes concerning the vessel age and classification conditions in relation to insurance payout
• When contamination causes in bulk liquid cargo span multiple transport segments
• When samples, certificates of quality, or analysis results contradict each other
• When distinguishing between natural cargo deterioration and external accident damage becomes problematic
• When high-value compensation claims are made by the cargo owner against the freight forwarder or NVOCC
• When deadlines for insurance claims, notices to the carrier, or filing suit are approaching

Practical Points

• MICA cargo refers to the group of goods traditionally categorized as major import cargoes in conventional marine cargo insurance practices.
• Since multiple English variations of MICA exist, it is important to verify the original document title.
• Typical cargoes include coal, fertilizers, grains, ores, oils, cotton, rice, salt, soybeans, sugar, and wool, among others.
• MICA cargo and the former tariff classifications do not directly indicate current premium rates or underwriting conditions.
• Historical documents should be used as reference materials to understand cargo-specific risk trends and inspection points.
• In current practice, cargo type, packaging, route, vessel, storage, and damage history are individually verified.
• The vessel’s age, classification, type, and stowage method are checked in combination with the nature of the cargo.
• When using older vessels, the Institute Classification Clause and age-related surcharges should be confirmed.
• “Held Covered” status may require prompt notification and negotiation of terms; it does not represent unconditional coverage continuation.
• For bulk liquid cargoes, the previous cargo, tank cleaning, piping, and sampling are critical considerations.
• Relevance to MICA cargo and the cause of individual incidents and claim payments are to be assessed separately.
• The freight forwarder’s liability should be determined based on their contractual scope of involvement, not the old cargo classifications.

Summary

MICA cargo refers to a group of cargoes that were categorized as major import cargo in the traditional foreign cargo insurance practice.

The abbreviation MICA is related to Major Import Cargo, and historical documents show multiple variations such as Major Import Cargo Tariff Agreement and Major Import Cargo Agreement Tariff.

Therefore, when explaining MICA, it is important not to treat a single English name as an absolute formal title but to check the original document’s title, issuing body, publication date, and definition.

Representative examples of MICA cargo include coal, fertilizer, grain, iron ore, manganese ore, oils, cotton, rice, salt, soybeans, sugar, and wool.

These cargoes were not only handled in large import volumes but each posed different risks such as water damage, spontaneous combustion, fire, mold, contamination, solidification, quantity discrepancies, residue of previous cargo, and inadequate tank cleaning.

The concept of MICA cargo and the old tariff items does not represent current premium rates or underwriting conditions.

In Japan, the deregulation of non-life insurance products and rates progressed following legal changes such as the revision of the Insurance Business Act implemented on April 1, 1996, and the amendment of the Act on the Rate Calculation Organizations of Non-Life Insurance in July 1998.

However, these historical regulatory changes alone do not allow a uniform conclusion about the revision or abolition dates of individual MICA documents, rate tables, or agreements.

In current foreign cargo marine insurance, insurers individually determine underwriting terms based on factors such as cargo type, quality standards, packaging, value, transport segment, route, vessel conditions, storage conditions, and damage history.

At the same time, the traditional practical approach of assessing risk by combining cargo type with vessel age, class, vessel type, stowage method, holds, tanks, previous cargo, and cargo handling conditions remains useful.

This viewpoint is helpful for bulk cargo underwriting inquiries, grain quality risk verification, issues related to moisture content and quantity in ores, contamination prevention in bulk liquid cargoes, vessel verification after changes, conventional vessel and heavy-lift transport, and initial investigation following accidents.

However, MICA cargo is a historical cargo classification, while the Institute Classification Clause is a clause confirming vessel suitability, and Held Covered concerns notification and condition negotiations when occurrences outside the terms arise.

Mere applicability to MICA cargo cannot determine vessel suitability, continuation of coverage under Held Covered, current premium rates, or claim payments.

Especially for bulk and bulk chemical cargoes, it is necessary to verify not only the cargo name but also the previous cargo, tank cleaning, piping, sampling, quality standards, and vessel conditions.

When using high-age vessels or vessels with unknown class, it is important to confirm the Institute Classification Clause, vessel age surcharge, and Held Covered conditions regardless of MICA cargo status.

For vessel changes or transshipments, reconfirm vessel name, IMO number, vessel age, classification, and Class Status not only for the originally planned vessel but also for the actual vessel loading the cargo after the change.

In case of accidents, do not determine the cause based solely on MICA cargo applicability or accident trends in historical materials. Handle the case based on the current insurance policy, applicable clauses, accident timeline, survey reports, samples, and various evidence documents.

Freight forwarders or NVOCCs must organize cargo information, transport methods, vessel conditions, vessel changes, insurance notifications, and accident documents according to their contractual involvement and provide accurate explanations to the shipper.

When referring to old MICA or tariff materials in practice, do not use them as current rate tables but as historical documents for extracting risk items by cargo.

To confirm current premium rates, coverage scope, surcharge premiums, applicability of Held Covered, or underwriting decisions, prepare cargo details, route, vessel information, storage conditions, and damage history, and consult with the insurer or a specialized insurance agent handling foreign cargo marine insurance.

This article provides general information and historical practical background. It does not determine the formal English name of MICA in specific documents, the application period of individual rates, current premium rates, coverage scope, vessel age surcharges, applicability of Held Covered, claim payment eligibility, accident causes, or the legal liabilities of shipping lines, shipowners, warehouses, freight forwarders, or NVOCCs.
