Open Policy (Marine Cargo Insurance)

Overview

An Open Policy is a form of Marine Cargo Insurance used for recurring exports, imports, or cross-trade shipments. The policyholder and insurer agree in advance on the principal underwriting framework, including covered cargo, routes, insurance conditions, rates, the method for calculating the Sum Insured, contractual limits, and other requirements, after which individual shipments are reported by Declaration.

Where a company handles frequent shipments entirely through individual insurance arrangements, delays in placement, uninsured shipments, inconsistent conditions, and delays in issuing insurance documents can arise. An Open Policy allows recurring shipments to be administered under pre-agreed conditions while standardising Declarations, issuance of insurance documents, and premium settlement.

An Open Policy does not, however, mean that every shipment of any kind is automatically and unconditionally insured. Covered cargo, geographical scope, contractual limits, exceptional cargo, declaration requirements, and the method for calculating the Sum Insured depend on the actual policy and applicable terms.

A Declaration is an important procedure for identifying and accounting for an individual shipment, but the time at which a Declaration is submitted is not necessarily the time at which insurance cover attaches. The attachment of cover, declaration deadline, effect of a late Declaration, and treatment of an omitted Declaration must be determined under the actual Open Policy and applicable clauses.

This article therefore treats an Open Policy not simply as an administrative convenience but as an operational system linking shipment data, Declarations, the Sum Insured, documentary credits, insurance documents, premium settlement, exceptional cargo, and claims management.

How an Open Policy Works

An Open Policy establishes an advance underwriting framework for recurring shipments that will arise during the policy period.

The agreed framework may address:

• Covered cargo
• Covered exports, imports, and cross-trade transactions
• Geographical and transit scope
• Institute Cargo Clauses and other insurance conditions
• War Risks, Strikes Risks, and other additional conditions
• Rates or rate-setting methodology
• Method for calculating the Sum Insured
• Contractual limits applying per shipment, conveyance, location, or other basis
• Prior approval for high-value or special cargo
• Method and timing of Declarations
• Issuance of insurance documents
• Premium accounting and settlement

When an individual shipment occurs, the policyholder reports the confirmed transportation details to the insurer or insurance intermediary in accordance with the agreed procedure.

Terminology: Open Policy and Open Cover

In Japanese Marine Cargo Insurance practice, the Japanese term for a continuing cargo arrangement is commonly translated as Open Policy.

International insurance and trade-finance practice also frequently uses the expression Open Cover, and UCP 600 Article 28 expressly refers to a “declaration under an open cover.”

Although Open Policy and Open Cover may describe closely related continuing cargo-insurance arrangements, their technical usage and contractual structure are not necessarily identical across jurisdictions, insurance markets, and insurers.

This article therefore uses Open Policy for the Japanese practical concept under discussion, but an overseas Open Cover should not automatically be assumed to have precisely the same contractual operation without reviewing its wording.

Individual Insurance, Provisional Insurance, and Open Policy

Arrangement	Typical Use	Information Available at Placement	Subsequent Procedure	Main Caution
Individual insurance	One-off shipment	Individual transport details are normally available	Insurance documents are managed for that shipment	High shipment volumes increase administrative workload and omission risk
Provisional Insurance	A specific shipment is expected but some details remain unknown	Some details remain provisional	Final details are subsequently declared	The final Declaration must not be overlooked
Open Policy	Recurring shipments over an extended period	General underwriting terms are pre-agreed	Individual shipments are reported by Declaration	Scope, limits, and declaration control are critical
Open Policy with Non-Policy arrangement	Frequent exports where issuance of individual policies is omitted	Open Policy framework is pre-agreed	Shipments are reported and accounted for under the agreed system	Confirm that counterparties and banks accept the documentary arrangement

Purpose of the Declaration

A Declaration is the procedure by which confirmed details of an individual shipment falling within the Open Policy are reported to the insurer or insurance intermediary.

Typical information may include:

• Policyholder and insured party
• Description of cargo
• Quantity and packages
• Invoice No.
• Invoice value
• Sum Insured
• Currency
• Shipment or transit commencement date
• Vessel or other conveyance
• B/L, Sea Waybill, or Air Waybill number
• Origin and destination
• Place of Receipt and Place of Delivery where relevant
• Trade term
• Special, dangerous, temperature-controlled, or other exceptional characteristics where relevant

The Declaration identifies the individual transit under the continuing contract and provides the basis for premium calculation, insurance documentation, and subsequent claims administration.

Do Not Equate Declaration Time with Attachment of Cover

It is inaccurate to state universally that no insurance exists until a Declaration is submitted and that cover begins at the moment the Declaration is transmitted.

Under some Open Policy structures, qualifying shipments may attach in accordance with the agreed transit and policy terms, while the Declaration operates as a subsequent reporting and accounting obligation.

Other shipments, such as high-value cargo, special cargo, or shipments to specified locations, may require prior notification or individual approval.

Item	Question	Risk of Misunderstanding	Practical Response
Attachment	When does insurance cover begin?	Treating the Declaration timestamp as the attachment time	Review the Transit Clause and policy terms
Declaration deadline	Must notification be made before shipment, after shipment, or periodically?	Late Declaration	Convert the contractual deadline into an internal control
Prior approval	Do high-value, special, or high-risk shipments require approval?	Processing an exception as an ordinary Declaration	Refer the shipment before dispatch
Omitted Declaration	How does the contract deal with an omission?	Assuming automatic relief	Report the omission immediately

Practical Declaration Flow

1. Determine from the sale contract which party is responsible for arranging Marine Cargo Insurance.
2. Confirm that the shipment falls within the transaction, cargo, and geographical scope of the Open Policy.
3. Check whether the shipment is high-value, special, dangerous, temperature-controlled, or otherwise exceptional.
4. Obtain cargo and transit data from the Invoice, Booking, Draft B/L, and other shipment records.
5. Review the Incoterms rule and contractual allocation of risk and insurance responsibility.
6. Calculate the Sum Insured under the agreed policy methodology.
7. For an L/C shipment, review the documentary-credit insurance requirements.
8. Submit the Declaration within the time and by the method required by the Open Policy.
9. Where necessary, obtain a Certificate of Insurance or Insurance Policy.
10. Compare the insurance document with the Invoice, B/L, L/C, and other relevant documents.
11. Record the Declaration and insurance-document reference numbers in the shipment register.
12. Reconcile all shipments against all Declarations each month to identify omissions, duplicates, and unprocessed cancellations.
13. Reconcile premium invoices and monthly settlements with the Declaration data.

Allocation of Operational Responsibilities

Party or Function	Main Role	Items to Confirm	Typical Risk	Control
Sales / Trade team	Establish commercial terms	Incoterms, price, and L/C	Misidentifying the party responsible for insurance	Record insurance responsibility when the transaction is booked
Logistics team	Manage shipment data	Shipment date, route, B/L, and cargo	Missing Declaration	Link insurance control to the shipment register
Insurance team	Declarations, insurance documents, and exception approval	Policy conditions, limits, and rates	Treating special cargo as ordinary cargo	Maintain exception rules
Accounting team	Premium settlement	Monthly premium, currency, and corrections	Duplicate or missing accounting	Reconcile against the Declaration list
Bank	Examine documents under an L/C	Credit terms, UCP 600, and banking practice	Discrepancy	Review documentary requirements before shipment
Freight forwarder	Assist with transit and insurance information to the extent instructed	Who is responsible for arranging insurance?	Each party assumes that the other arranged cover	State the insurance responsibility in the quotation or Booking
Insurer / insurance intermediary	Underwriting, exception approval, documentation, and claims handling	Actual policy and clauses	Underwriting based on incomplete information	Refer exceptional risks before shipment

Omitted or Incorrect Declarations

One of the principal operational risks under an Open Policy is an omitted, late, or inaccurate Declaration.

Discovery of an omitted Declaration does not necessarily mean that the shipment is automatically uninsured, nor does it mean that the omission will automatically be excused.

The outcome may depend on the Declaration Clause and other policy terms, whether the shipment was within the agreed scope, the nature of the reporting obligation, the cause of the omission, whether a casualty has occurred, when the omission was discovered, and the parties’ established operating arrangements.

If an omission is discovered after a casualty, the policyholder should not attempt to obscure the sequence of events by processing the shipment as though it were an ordinary timely Declaration. The omission, discovery time, and circumstances should be disclosed promptly to the insurer or insurance intermediary.

Setting the Sum Insured

An Open Policy may specify an agreed methodology for determining the Sum Insured for each shipment.

Marine Cargo Insurance frequently uses a CIF or CIP-based value with an agreed additional percentage.

If a policy provides for a Sum Insured equal to 110% of a CIF value of USD 100,000, the Sum Insured would be USD 110,000.

This does not mean, however, that every Marine Cargo Insurance contract is universally required to use CIF × 110%. The actual methodology depends on the insurance contract, sale terms, and any documentary-credit requirements.

Distinguishing Insurable Value and Sum Insured

Item	Meaning	Typical Use	Caution
Invoice Value	Commercial invoice amount	Sale transaction and L/C	Not necessarily identical to CIF value
CIF / CIP Value	Value reflecting the cost components of the agreed trade term	Insurance calculations and L/C documentation	FOB and CFR structures differ
Insurable Value	Economic value relevant to the insurance subject matter	Insurance and loss assessment	Not synonymous with Sum Insured
Sum Insured	Amount insured for the individual shipment	Insurance document and premium calculation	Apply the policy methodology
Contractual Limit	Maximum amount permitted under the Open Policy on a specified basis	High-value exception control	Not necessarily the same concept as the Sum Insured

UCP 600 Article 28 and Insurance Documents

Where a documentary credit subject to UCP 600 requires an insurance document, Article 28, “Insurance Document and Coverage,” is a central rule.

Among the matters addressed under Article 28 are:

• Presentation of an Insurance Policy, Certificate of Insurance, or declaration under an open cover as permitted by the credit and UCP 600
• Issuance and signature by an insurance company, underwriter, or their agent or proxy
• Non-acceptance of a Cover Note
• Acceptance of an Insurance Policy where the credit calls for an Insurance Certificate or a declaration under an open cover
• The insurance document should not be dated later than the date of shipment unless the document itself establishes that coverage was effective from a date not later than shipment
• The amount of insurance is to be expressed in the same currency as the credit
• Where the credit does not indicate the amount of insurance required, the amount is generally to be at least 110% of the CIF or CIP value
• The insurance document must satisfy the required transit and risks stated in the credit

Accordingly, it is also inaccurate to state that an insurance document dated after the B/L or shipment date must always constitute a discrepancy.

If the insurance document itself establishes that insurance coverage was effective from a date no later than the shipment date, Article 28 treats the position differently.

Do Not Confuse the UCP 600 110% Rule with the Open Policy Calculation

The 110% reference in UCP 600 Article 28 is not a general rule of insurance law requiring every Marine Cargo Insurance contract to insure every shipment at 110%.

It operates as a documentary-credit rule where the credit does not itself indicate the required amount of insurance.

An Open Policy may separately provide that individual shipments are insured at 110% of CIF or CIP value.

CIF and CIP sales arrangements may also impose insurance obligations on the seller.

Context	Source	Main Purpose	Practical Caution
Open Policy Sum Insured	Insurance contract	Determine the Sum Insured for each shipment	The policy may use another agreed formula
CIF / CIP sale	Sale contract and applicable Incoterms rule	Determine the seller’s insurance obligation	CIF and CIP do not necessarily require identical standard levels of cover
L/C document examination	Credit and UCP 600 Article 28	Determine documentary compliance of insurance amount	Any express amount stated in the credit must be examined first

Do Not Delay a Declaration in an L/C Transaction

Even where an Open Policy operationally permits a Declaration after shipment, a separate issue arises where an L/C requires an Insurance Certificate or other insurance document for presentation to a bank.

The exporter must therefore consider not only the latest Declaration time permitted under the Open Policy but also the time by which a complying insurance document must be available.

The insurance document date, effective coverage, currency, Sum Insured, Institute Cargo Clauses, War Risks, Strikes Risks, insured party, and any required endorsement should be reviewed before shipment wherever possible.

Relationship with ISBP 821

ISBP 821, the 2023 edition of the International Standard Banking Practice, provides detailed banking practice for examination of documents under documentary credits subject to UCP 600.

For insurance documents, it provides practical guidance concerning application of UCP 600 Article 28, issuer and signature, Originals, dates, amount and percentage of cover, risks, insured party and endorsement, terms and conditions, and insurance premium.

Accordingly, an L/C shipment should be reviewed by considering the terms of the credit, UCP 600, and ISBP 821 together.

Certificate of Insurance

Under an Open Policy, a Certificate of Insurance or another insurance document may be issued for an individual shipment.

The document does more than demonstrate that a continuing Open Policy exists. It may identify the particular cargo, transit, Sum Insured, currency, and insurance conditions applicable to that shipment.

Typical items include:

• Insured or Assured
• Cargo description
• Invoice No.
• B/L or other transport information
• Voyage or Transit
• Sum Insured
• Currency
• Institute Cargo Clauses
• War and Strikes conditions
• Certificate No.
• Issue Date
• Any required endorsement

For an L/C shipment, it is not sufficient that the shipment is properly insured under the Open Policy. The insurance document presented to the bank must itself comply with the documentary-credit requirements.

Monthly Settlement and Consolidated Declarations

An Open Policy may permit multiple shipments to be reported or accounted for on a monthly or other consolidated basis.

This does not mean that shipment-level control can be suspended until month-end.

Operational records should capture individual shipments and support reconciliation of:

• Total shipments
• Total Declarations
• Invoice Nos.
• B/L or other transport references
• Cargo values
• Sums Insured
• Currencies
• Rates
• Corrections and cancellations
• Individual approvals for exceptional cargo

Whether monthly consolidated reporting is permitted must be determined under the relevant insurer and Open Policy arrangement.

High-Value Cargo and Contractual Limits

An Open Policy may contain contractual limits applying per shipment, vessel, aircraft, location, or another aggregation basis.

Entering a Sum Insured exceeding that limit in an ordinary Declaration does not necessarily mean that the excess amount has automatically been accepted on ordinary terms.

For high-value cargo, review:

• Total cargo value
• Sum Insured
• Applicable contractual limit
• Aggregation on the same vessel or conveyance
• Packing and transport method
• Transshipment
• Special cargo conditions
• Requirement for prior approval
• Additional Premium or special conditions

Special and Exceptional Cargo

An Open Policy defines the cargo falling within its agreed scope.

Used machinery, fine art, exhibition goods, precious metals, temperature-controlled cargo, pharmaceuticals, dangerous goods, live animals, and other cargo may require treatment different from ordinary cargo.

The correct question is not whether a particular category is universally excluded from Open Policies. The question is whether the particular Open Policy classifies that cargo as ordinary, conditional, subject to prior approval, or excluded.

Exports, Imports, and Cross-Trade Shipments

Transaction	Main Issues	Important Declaration Data	Practical Caution
Export	Sale term, L/C, and insurance responsibility	Invoice, route, Sum Insured, and Certificate	Review L/C insurance requirements early
Import	Whether the importer is responsible for arranging insurance	Purchase value, Freight, Transit, and Currency	Maintain consistency with customs insurance-cost documentation
Cross trade	Policy scope, risk allocation, and insurable interest	Foreign origin and destination, sale contract, and Invoice	Do not decide scope solely because the goods do not enter Japan
Overseas affiliate shipment	Policyholder and insured-party structure	Entities, cargo movement, and commercial relationship	Group-company status does not automatically establish coverage

Relationship with the Freight Forwarder

The existence of an Open Policy held by the cargo owner does not automatically impose a duty on the freight forwarder to submit Declarations.

Conversely, where the freight forwarder has been expressly instructed to arrange insurance, its agreed role may include assisting with insurance placement, Declaration data, or requests for insurance documentation.

A particularly serious operational risk arises where the cargo owner assumes that the freight forwarder will arrange insurance while the freight forwarder assumes that the cargo owner will use its own Open Policy.

The party responsible for arranging Marine Cargo Insurance should therefore be identified at the quotation, Booking, or Shipping Instruction stage.

Relationship with Customs Practice

For imports, insurance cost may become relevant to customs valuation documentation.

The fact that cargo is insured under an Open Policy does not by itself remove the need to establish the relevant insurance cost for customs purposes where required.

Where simplified or comprehensive customs procedures are used in relation to insurance, their specific requirements must be confirmed separately.

Invoice Value, Freight, Insurance, Incoterms, and customs value should not be treated as interchangeable figures.

Steps after a Cargo Casualty

1. Protect safety and take reasonable steps to prevent further loss.
2. Record the date, location, and cargo condition with photographs, video, and other evidence.
3. Confirm that the shipment falls within the Open Policy scope.
4. Check whether a Declaration was made and whether its information is accurate.
5. If an omitted Declaration is discovered, do not retrospectively process it without explanation; contact the insurer or insurance intermediary.
6. Review the Certificate of Insurance, Invoice, B/L, and other shipment records.
7. Identify the applicable Institute Cargo Clauses and other conditions.
8. Coordinate with the insurer regarding any required Survey.
9. Issue a Claim Notice to the Carrier or other potentially responsible party and preserve rights of recovery.
10. Collect evidence of loss, repair costs, salvage value, and other quantum information.
11. Manage the insurance claim separately from recovery against the Carrier or another responsible party.

Cases Commonly Problematic in Practice

Case	Main Problem	Items to Confirm	Response
Omitted Declaration	Treatment of the unreported shipment	Policy terms, scope, cause of omission, and casualty status	Report immediately when discovered
Late Declaration	Declaration deadline and L/C document date	Open Policy and UCP 600	Analyse the insurance contract and L/C separately
High-value cargo	Contractual limit exceeded	Sum Insured, aggregation, and prior approval	Refer before shipment
Special cargo	Applicability of ordinary rate and conditions	Cargo conditions and endorsements	Obtain confirmation before ordinary Declaration
L/C insurance document	Bank discrepancy	Currency, amount, date, and coverage	Review before shipment
Cross trade	Whether the transaction falls within policy scope	Territory, sale terms, and insurable interest	Confirm before commencing the trade
Different assumptions between cargo owner and forwarder	No insurance is arranged	Quotation, Booking, and instructions	Document who is responsible for arranging insurance
Failure to reconcile monthly declarations	Missing or duplicate reporting	Shipment register and Declaration list	Perform monthly reconciliation

Application Scenario 1: Insurance-Document Date under an L/C

The following is a hypothetical example for practical analysis.

Automotive parts with an Invoice value of JPY 36 million are exported from Nagoya to Hamburg on CIF terms under a documentary credit.

The credit requires Institute Cargo Clauses (A), Institute War Clauses, and Institute Strikes Clauses.

The exporter has an Open Policy but waits until the B/L and other shipment documents are available before submitting the Declaration. The Declaration is therefore made two days after shipment.

The resulting Certificate of Insurance is also dated two days after shipment and contains no statement establishing that cover was effective from a date no later than the shipment date.

The negotiating bank raises a discrepancy under the insurance-document requirements of UCP 600 Article 28.

The exporter argues that the Open Policy itself was already in existence before shipment and that the cargo was substantively insured.

The bank responds that it is not determining substantive insurance coverage but examining whether the insurance document presented under the credit complies with UCP 600 and the terms of the credit.

The key point is that insurance coverage under the Open Policy and documentary compliance of the Insurance Document are separate issues.

Application Scenario 2: Omitted Declaration Discovered after a Casualty

Electronic components valued at JPY 42 million are imported from Shanghai to Yokohama under an annual Open Policy.

On arrival, wet damage of JPY 12 million is discovered.

When the insurance register is checked, the importer discovers that this particular shipment was never declared.

The importer argues that the shipment should automatically be covered because a continuing annual Open Policy is in force and the omission was administrative.

The insurer responds that it must review whether the cargo falls within the policy scope, the Declaration Clause, the cause of the omission, ordinary reporting procedures, and the timing of the casualty.

The correct response is not to process the Declaration retrospectively as if nothing unusual had occurred, but to disclose the omission and its circumstances immediately.

Application Scenario 3: High-Value Shipment Exceeding the Contractual Limit

Semiconductor manufacturing equipment with a Sum Insured of JPY 180 million is to be shipped from Kobe to Houston.

The Open Policy contains a contractual limit of JPY 100 million for an ordinary shipment, with prior referral required above that level.

The logistics team assumes that entering JPY 180 million in the normal Declaration will automatically insure the full amount.

The insurance team identifies the issue shortly before shipment and refers it to the insurer.

The insurer requests information concerning cargo value, packing, transportation method, and transshipment before making an individual underwriting decision.

The logistics team argues that the goods are ordinary machinery already falling within the Open Policy cargo category.

The insurer explains that falling within the cargo category and remaining within the contractual monetary limit are separate requirements.

Application Scenario 4: Cross-Trade Shipment outside the Usual Route

A Japanese trading company purchases machinery parts worth USD 600,000 from a Korean manufacturer for direct shipment from Busan to a buyer in Jakarta.

The goods do not enter Japan.

The sales team assumes that the shipment is automatically covered by the existing export Open Policy because the Japanese company remains the seller.

The insurance team notes that the existing policy is principally structured around exports from Japan and asks the insurer whether the cross-trade shipment falls within the agreed scope.

The sales team argues that the transaction remains part of the Japanese company’s sales activity.

The insurer responds that accounting treatment of the sale and the geographical and transactional scope of the Open Policy are separate questions.

The policy territory, trade terms, risk allocation, insurable interest, and insured party should therefore be confirmed before shipment.

Application Scenario 5: Used Machinery Declared as Ordinary Machinery

Used machine tools with an Invoice value of JPY 55 million are exported from Osaka to Singapore.

The logistics team submits the Declaration using the ordinary cargo classification “Machinery.”

The insurance team subsequently discovers that used machinery is subject under the particular Open Policy to individual referral or additional conditions.

The sales team argues that the goods are machinery and should therefore receive the ordinary Machinery Rate.

The insurer responds that used machinery may require separate consideration of pre-existing damage, condition, packing, and evidence of the pre-shipment state, and therefore cannot be processed under the ordinary Declaration route in that contract.

The key point is that a cargo description available in a Declaration system does not necessarily establish that the cargo qualifies for ordinary cover under the insurance contract.

Common Misconceptions

Misconception	Actual Practice	Practical Caution
An Open Policy automatically and unconditionally covers every shipment	Cargo scope, geography, limits, and special conditions must still be reviewed	Maintain an exception-screening process
Insurance begins when the Declaration is submitted	Attachment of cover and Declaration time are not necessarily identical	Review the policy and Transit Clause
An omitted Declaration is always automatically cured later	The result depends on policy terms and facts	Report promptly rather than assuming cover
Every shipment under an Open Policy must be insured at CIF × 110%	The policy may specify another methodology	Distinguish the insurance contract from UCP rules
UCP 600 requires every cargo insurance contract to use 110%	The Article 28 rule concerns documentary-credit insurance amount where the credit does not specify the required amount	Read the credit first
An insurance document dated after shipment is always discrepant	The position differs where the document establishes that cover was effective no later than shipment	Review both Issue Date and effective coverage
A Cover Note may always be presented instead of an Insurance Certificate	UCP 600 Article 28 does not accept a Cover Note	Provide the required insurance document
Open Policy and Open Cover always mean exactly the same contract worldwide	Terminology and structure may differ between markets and jurisdictions	Review the actual contract
Monthly consolidated reporting removes the need for daily shipment records	Shipment-level records are still required for reconciliation	Match the shipment register against Declarations
If the cargo owner has an Open Policy, the freight forwarder need not clarify insurance arrangements	Different assumptions may result in no insurance being arranged	Clarify responsibility at Booking

When to Consult a Maritime Lawyer

• An omitted Declaration is discovered after a casualty and coverage is disputed
• The legal effect of a breach of the Declaration obligation is disputed
• The attachment or termination of cover under the Open Policy is unclear
• Coverage above a contractual limit is disputed for a high-value shipment
• It is unclear whether special cargo falls within the ordinary policy scope
• Insurable interest, insured-party status, or governing law is disputed in a cross-trade transaction
• The cargo owner and freight forwarder dispute which party was contractually responsible for arranging insurance
• An L/C discrepancy develops into a substantial payment dispute
• A substantial Subrogated Recovery is pursued against a Carrier or another responsible party
• An overseas Open Cover and a Japanese Open Policy appear to operate differently and the contractual relationship is disputed

Summary

An Open Policy is an important Marine Cargo Insurance arrangement for recurring exports, imports, and cross-trade shipments, under which the principal underwriting framework is agreed in advance and individual shipments are administered through Declarations and related procedures.

Its value is not limited to reducing administrative work. It can create an integrated process for preventing uninsured shipments, standardising insurance conditions, issuing insurance documents, managing documentary-credit requirements, settling premiums, and confirming insurance after a casualty.

An Open Policy does not, however, mean that every shipment is automatically covered without conditions. Covered cargo, territorial scope, contractual limits, special cargo, Declaration requirements, and prior-approval provisions must still be reviewed.

A Declaration is an important mechanism for identifying an individual shipment, but its submission time should not automatically be equated with the attachment of insurance cover. The effect of a late or omitted Declaration depends on the actual Open Policy and applicable clauses.

For documentary-credit transactions, substantive insurance under the Open Policy and documentary compliance of the Insurance Document are separate questions. The credit terms, UCP 600 Article 28, and ISBP 821 should be reviewed together, including the Sum Insured, currency, date, period of cover, risks, and type of insurance document.

The most important operational control under an Open Policy is to ensure that sales, trade, logistics, insurance, and accounting teams use the same shipment data and continuously reconcile every shipment against every Declaration.
