Marine Cargo Insurance — Setting the Sum Insured

How Is the Sum Insured Set for Marine Cargo Insurance?

The sum insured is the amount stated in the insurance contract as the maximum amount recoverable in respect of the insured cargo, subject to the applicable policy terms. It also serves as a basis for premium calculation.

Stating a sum insured does not mean that the same amount will automatically be paid following a loss. The amount recoverable is determined by the recognized amount of loss, the insurable value or agreed value, the applicable policy terms, deductibles, salvage value, other insurance, and other contractual provisions.

The sum insured, insurable value, agreed value, CIF value, and premium are therefore separate concepts and must not be used interchangeably.

In marine cargo insurance for international shipments, it is generally customary to set the sum insured at 110% of the CIF value, that is, the CIF value plus 10%. However, this practice is not automatically applicable to all cargo, contracts, and transactions.

In practice, the invoice amount, trade term, freight charges, premium, currency, sales contract, letter of credit terms, applicable Open Cover Agreement, cargo valuation documents, and the insurer’s underwriting conditions should be confirmed.

Differences Between the Sum Insured, Insurable Value, and Agreed Value

To correctly set the sum insured, it is important not to confuse the related monetary concepts.

Term	Meaning	Practical Role	Main Reference Documents
Sum Insured	The amount stated in the insurance contract as the maximum amount recoverable in respect of the insured cargo, subject to the applicable policy terms	This is the sum insured shown on the insurance policy, insurance schedule, or final declaration and serves as a basis for premium calculation.	Insurance policy, insurance schedule, final declaration
Insurable Value	The monetary valuation of the insured interest	Serves as a basis for underinsurance and overinsurance, and damage assessment calculations.	Invoice, sales contract, valuation documents, freight charges documentation
Agreed Value	The insurable value agreed between the insurer and the insured when the insurance contract is concluded	Serves as the agreed valuation basis, subject to the applicable policy terms.	Insurance contract, valuation report, records of agreement with the insurer
CIF Value	The transaction value including cargo cost, freight, and premium	Widely used as the basis for calculating the sum insured in marine cargo insurance for international carriage.	Invoice, freight details, premium calculation documents
CIF × 110%	A method of setting the sum insured by adding 10% to the CIF value	A common practice in marine cargo insurance underwriting; it is a calculation method and not synonymous with sum insured or insurable value itself.	Insurance application form, Open Cover Agreement, insurer’s calculation method
Premium	The consideration paid by the policyholder to the insurer for the insurance contract	Generally calculated based on the sum insured, premium rate, minimum premium, and other conditions.	Premium calculation statement, insurance schedule
Amount of Loss	The economic loss recognized as a result of an insured event	A concept distinct from the sum insured and serves as the basis for payout calculation according to the insurance terms.	Survey report, repair estimates, valuation documents

The sum insured represents the payment limit, while the insurable value represents the value of the insured interest. The agreed value is the insurable value agreed between the insurer and the insured when the insurance contract is concluded.

The CIF value and CIF × 110% represent the basis or calculation method for setting the sum insured, and should not be considered synonyms for the sum insured or insurable value.

Basic Flow for Setting the Sum Insured

1. Verify the description, quantity, unit price, and transaction value of the cargo.
2. Confirm the trade term and currency stated on the invoice.
3. Determine who is responsible for arranging the marine cargo insurance under the sales contract.
4. Check whether the invoice amount includes freight, premium, and other charges.
5. Calculate the CIF value or the basic value as specified by the insurance company.
6. Review the insurance percentage, such as 110%, according to the sales contract, letter of credit, and insurance policy.
7. Confirm the currency of the sum insured and the method of currency conversion.
8. If the cargo is free of charge, used goods, or high-value items, provide additional valuation documents.
9. Inquire with the insurance company or insurance agent about the sum insured, policy terms, and underwriting acceptance.
10. Before issuing the insurance policy or final declaration, recheck the amount, currency, route, cargo details, and policy terms.

Key Documents to Verify When Setting the Sum Insured

Documents / Information to Verify	Details to Confirm	Impact on Sum Insured	Practical Considerations
Commercial Invoice	Cargo price, currency, trade term, quantity, and unit price	Confirms the transaction value that forms the basis for the sum insured.	Check whether freight and premium are included under the stated trade term.
Sales Contract	Sale price, trade term, obligation to arrange insurance, and insurance percentage	Verifies the insurance arrangements agreed upon by the contracting parties.	Do not rely solely on invoice details; review the full contract text.
Freight Details	Ocean freight, air freight, inland freight, and related charges	Used to calculate CIF-equivalent value from FOB, FCA, EXW, etc.	Distinguish between estimated and finalized freight charges.
Premium Calculation Conditions	Premium rate, minimum premium, and calculation method	Relevant when deriving CIF-equivalent value from CFR or FOB amounts.	Because the premium and the sum insured are interdependent, use the calculation method prescribed by the insurer.
Packing List	Number of packages, quantity, weight, and volume	Confirms allocation of amounts for partial shipments or multiple shipments.	Ensure quantities match those on the invoice.
Letter of Credit	Sum insured, insurance percentage, currency, insurance terms, and insurance certificate description	Checks insurance certificate requirements under letter of credit transactions.	Even if appropriate for insurance practice, conditions may conflict with letter of credit terms.
Open Cover Agreement	Value setting, exchange rate, final declaration, and applicable conditions	Verifies calculation methods applied for ongoing transactions.	Avoid changing calculation methods on a case-by-case basis.
Appraisal / Valuation Report	Market value, replacement cost, and used value	Used when no transaction value exists or the transaction value does not reflect the actual situation.	Confirm the appraisal date, purpose, and subject of the valuation.
Repair / Reproduction Estimate	Value of repaired goods, replacements, or own company’s equipment	Serves as reference for cargo not sufficiently explained by invoice value alone.	May require prior approval from the insurer.

Approach Based on CIF Value

In marine cargo insurance, the CIF value—comprising the cargo price, freight charges, and premium—is generally used as the basis for setting the sum insured.

The CIF value includes not only the price of the cargo itself but also the freight to the destination port and the marine cargo premium.

If only the cargo price is used as the basis for the sum insured, there is a possibility that the freight and other costs already incurred may not be sufficiently reflected in the sum insured in the event of a total loss.

However, the CIF value does not always correspond exactly to the insurable value or actual loss at the time of an incident. The CIF value is organized as a common baseline for setting the sum insured.

Why the Sum Insured Is Commonly Set at 110% of the CIF Value

In Japanese marine cargo insurance for overseas shipments, it is common practice to set the sum insured at 110% of the CIF value, which means adding 10% to the CIF value.

This additional 10% is a customary commercial margin intended to cover anticipated profit and various expenses that may arise in the event of a loss, within a reasonable range.

Adding 10% to the usual CIF value is a typical underwriting practice based on a rational setting rationale and does not by itself indicate inappropriate overinsurance.

However, the following three categories differ in their basis:

Category	Description	Main Basis	Items to Confirm
General Setting for Marine Cargo Insurance	Practice of setting the sum insured at 110% of the CIF value	Underwriting practice of insurance companies, Open Cover Agreement, and commercial custom	Confirm the insurable value calculation method prescribed by the insurer.
Insurance Arrangement Obligations under Incoterms	Seller’s obligation to arrange insurance for the buyer under CIF or CIP terms	Incoterms rules adopted in the sales contract	Verify the required sum insured, coverage terms, and insurance period.
Requirements in Letters of Credit	Amount, currency, and conditions required by the letter of credit for the insurance policy	Letter of credit text and applicable UCP rules	Check that submitted documents meet the letter of credit conditions.

Therefore, instead of mechanically applying CIF × 110%, it is necessary to individually verify the sales contract, letter of credit, Open Cover Agreement, and the insurer’s underwriting conditions.

Insurance Arrangement and the Sum Insured under Incoterms

Incoterms are contractual rules between the seller and buyer that define the allocation of transportation, insurance, costs, and risk.

Under Incoterms, the seller is explicitly obligated to arrange insurance notably under CIF and CIP terms. However, the applicable transport modes and the standard coverage levels differ between CIF and CIP.

Incoterm	Party Required to Arrange Insurance under Incoterms	Basis for Confirming Sum Insured	Main Points of Caution
CIF	Seller	Contract value, CIF value, and specification under the sales contract	Applicable to sea and inland waterway transport. Incoterms 2020 generally requires coverage equivalent to the minimum cover under ICC (C), unless otherwise agreed.
CIP	Seller	Contract value and specification under the sales contract	Applicable to multiple transport modes. Incoterms 2020 generally requires coverage equivalent to ICC (A), unless otherwise agreed.
CFR	No party is required to arrange insurance under Incoterms.	CFR value adjusted under the insurer’s prescribed calculation method to derive the CIF-equivalent value	Seller bears freight costs but typically has no insurance arrangement obligation under Incoterms.
FOB	No party is required to arrange insurance under Incoterms.	FOB value, actual ocean freight, and the insurer’s prescribed calculation method	FOB value alone excludes freight and premiums, so coverage insufficiency should be noted.
FCA	No party is required to arrange insurance under Incoterms.	FCA value, main carriage costs, and the insurer’s prescribed calculation method	FCA may be more appropriate than FOB for containerized cargo and similar shipments.
EXW	No party is required to arrange insurance under Incoterms.	EXW value, collection costs, export-related costs, main carriage costs, and the insurer’s prescribed calculation method	Confirm the start point of coverage and which transport costs are included.
DAP	No party is required to arrange insurance under Incoterms.	Breakdown of sales price and actual insured segment	Includes inland transport costs at destination; the full sales price may not be used as the basis.
DDP	No party is required to arrange insurance under Incoterms.	Breakdown of sales price and actual insured segment	Distinguish customs duties, import taxes, clearance fees, and local delivery costs at destination.

Incoterms do not prohibit either seller or buyer from arranging additional insurance independently. When sales contracts deviate from standard Incoterms provisions, the negotiated agreements should be confirmed.

Setting the Sum Insured under CFR Terms

The CFR value typically includes the cargo cost and freight to the destination port, but does not include premiums.

Under CFR terms, the sum insured is set by adding the premium to the CFR value to calculate an equivalent CIF value, which then serves as the basis for the sum insured.

However, since the premium is calculated based on the sum insured, simply adding an arbitrary premium can result in a circular calculation.

In actual calculation, the premium rate, calculation formula, minimum premium, and rounding procedures defined by the insurer or insurance agent are used. Do not finalize or confirm the amount based solely on rough self-estimates.

Setting the Sum Insured under FOB Terms

The FOB value typically does not include ocean freight or marine cargo premiums up to the port of destination.

Under FOB terms, the sum insured is determined by adding the actual ocean freight and other insurable costs to the FOB value, then calculating the premium and the CIF-equivalent value according to the insurance company’s specified method.

If the ocean freight is not yet finalized, the estimated or planned freight rate to be used should be confirmed with the insurer or insurance agent beforehand, and it should be checked after finalization whether any correction is necessary.

If only the FOB value is used as the sum insured, the ocean freight and other costs will not be reflected in the sum insured in the event of a total loss, potentially resulting in inadequate coverage.

When Using DAP or DDP Pricing

The DAP or DDP sale price may include inland transportation costs at the destination, import customs clearance fees, customs duties, import taxes, handling charges, and other expenses.

Do not use the full sale price as the basis for the sum insured. Instead, separate the cargo value and transportation costs subject to insurance from costs excluded from insurance or requiring separate confirmation.

Cost Item	Possibility of Inclusion in DAP/DDP Price	Treatment When Setting Sum Insured	Points to Confirm
Cargo Value	Usually Included	Serves as the primary basis for the sum insured.	Confirm the actual transaction value.
International Freight	Usually Included	Confirm as a cost corresponding to the insured transport segment.	Obtain freight breakdown details.
Destination Inland Transportation	May Be Included	Confirm whether it falls within the insurance period and insured transport segment.	Check insurance terms up to the final destination.
Import Customs Clearance Fees	May Be Included	Separate from the cargo value for organization.	Confirm with the insurer whether to add them as insured costs.
Customs Duties and Import Taxes	May Be Included under DDP	Even if included in the sale price, they do not necessarily form the basis for marine cargo insurance.	Individually confirm, including any customs duty insurance.
Installation and Trial Operation Costs	May be included depending on contract	May represent a different risk from standard marine cargo insurance.	Confirm the necessity of installation insurance or special endorsements.

Verification of Currency and Exchange Rates

When setting the sum insured, confirm not only the invoice amount but also the currency in which the sum insured will be stated.

When insuring foreign currency cargo in Japanese yen, do not use an arbitrary exchange rate. Instead, confirm the conversion reference date and the applicable rate specified by the Open Cover Agreement, the insurer, or the insurance agent.

Verification Item	Details to Confirm	Main Issues	Practical Measures
Invoice Currency	Trade currency such as USD, EUR, JPY, etc.	May differ from the currency on the insurance certificate.	Convey the currency code and amount accurately.
Currency Displayed on Insurance Certificate	Currency in which the sum insured is stated	May cause discrepancies with the L/C or sales contract.	Confirm the specified currency before certificate issuance.
L/C Specified Currency	Currency required by the Letter of Credit for the insurance certificate	Potential document inconsistency during bank review.	Cross-check the L/C text with the insurance certificate.
Conversion Reference Date	Invoice date, shipment date, final declaration date, etc.	The JPY amount varies depending on the date used.	Use the reference date prescribed in the contract.
Exchange Rate Used	Insurer’s specified rate, bank rate, etc.	Staff may use arbitrary exchange rates.	Confirm the rate as specified by the Open Cover Agreement or insurer.
Rounding Procedure	Handling fractions below one yen or decimal points in foreign currency	Discrepancies between certificate amounts and internal calculations.	Confirm the prescribed rounding or truncation method.
Multiple Currencies	When a single shipment includes cargo invoiced in multiple currencies	Cannot simply sum amounts.	Confirm the method to convert into the base currency.
Exchange Rate Fluctuation	Significant exchange rate changes after insurance purchase	JPY-converted amounts may diverge from actual values.	Confirm adjustment methods or correction possibilities under the Open Cover Agreement.

Items to Verify in Letter of Credit Transactions

In letter of credit transactions, it is important to separately verify whether the sum insured is reasonable for insurance purposes and whether the insurance policy presented to the bank complies with the letter of credit conditions.

The letter of credit may specify the insurance coverage percentage relative to the invoice value or contract value, currency, policy termss, insurance period, issue date, and the format of the insurance policy.

Verification Item	Common Issues in Letters of Credit	Practical Verification	Action When Discrepancies Occur
Sum Insured	Specification of at least 110% of the invoice value, etc.	Confirm that the sum insured on the policy meets the required percentage.	Check with the insurer or insurance agent whether corrections are possible.
Currency	Mismatches among invoice, letter of credit, and insurance policy currencies	Confirm the specified currency and conversion conditions.	Verify with the bank and insurance parties.
Insurance Clauses	Requested clauses such as ICC (A), War, Strikes not reflected in the policy	Compare the required clauses with the actual underwriting terms.	Consider additional coverage or amending the letter of credit conditions.
Insurance Period	Insufficient description of loading place, destination, or warehouse coverage	Match the shipping route noted in the letter of credit with the route stated in the policy.	Confirm the insurance period and actual transport details with the insurer.
Issue Date	Policy date is later than the shipment date	Check whether retroactive coverage is possible and verify letter of credit conditions.	Urgently inquire with the bank and insurer.
Cargo Description	Discrepancies in product name, quantity, B/L number, etc., with other documents	Cross-check the invoice, B/L, and insurance policy.	Consider correcting errors or amending the letter of credit conditions.

When setting the sum insured to satisfy letter of credit conditions, do not simply declare an amount unrelated to actual value. Instead, verify the sales contract, letter of credit, insurer's underwriting conditions, and basis of valuation.

Points to Consider Regarding Underinsurance

A situation in which the sum insured is less than the insurable value or agreed value is generally described as underinsurance.

When the sum insured is insufficient, not only will coverage not extend beyond the sum insured in total loss cases, but depending on the contract terms, it may also affect the calculation of claim payments in partial loss situations.

Specific payout methods vary depending on the applicable policy terms, whether an agreed value applies, the sum insured, and the type of loss.

Cause of Deficiency	Typical Example	Possible Issues	Practical Measures
Excluding freight	Insured only for FOB value	The sum insured is insufficient relative to the CIF-equivalent value.	Confirm the calculation method including freight and premium.
Insufficient insurance percentage	Insured at 100% although L/C demands 110%	Coverage deficiency or discrepancy with letter of credit requirements arises.	Cross-check L/C requirements and documentary amounts.
Incorrect exchange rate	Used an outdated exchange rate with strong yen	JPY sum insured is lower than actual value.	Use the prescribed conversion date and exchange rate.
Failure to reflect quantity changes	Shipment quantity increased after final declaration	The increased quantity is not included in the sum insured.	Confirm correction notices or additional insurance.
Misallocation in partial shipments	Total contract amount not properly allocated per shipment	The sum insured is insufficient for specific shipments.	Allocate by quantity, unit price, and shipment.

Points to Consider Regarding Overinsurance

Setting a sum insured that exceeds the insurable value without reasonable grounds does not mean that the excess portion will be paid out as insurance proceeds.

Marine cargo insurance is, in principle, a type of insurance that compensates for actual damages incurred. Even if the sum insured is high, the indemnity is calculated in accordance with the recognized amount of loss, insurable value, agreed value, policy terms, and payment limits.

On the other hand, setting the sum insured at 110% of the CIF value to allow for anticipated profit and related expenses is a common marine cargo insurance practice and does not by itself constitute inappropriate overinsurance.

Items to Confirm	Examples of Problems	Potential Supporting Documents	Response
Value of Used Goods	Declared based on new replacement cost without justification	Sales price, market value, replacement cost, appraisal report	Present the basis for valuation to the insurer in advance.
Free Goods	Set a high nominal amount without considering commercial value	Equivalent product price, manufacturing cost, appraisal documents	Consult the insurer on reasonable valuation methods.
Transactions Between Related Companies	Used internal transfer price directly as market value	Third-party transaction price, manufacturing cost, appraisal report	Clarify the nature of the transaction price.
Re-manufacturing Costs	Double-counted cargo value and re-manufacturing costs	Re-manufacturing estimate, design cost, material cost	Confirm the scope of the compensable value.
Installation Costs and Others	Included all costs unrelated to cargo transportation	Contract itemization, construction estimate	Separate marine cargo insurance and installation risk.

Cargo for Which the Invoice Amount Cannot Be Used As Is

Not all cargo has a standard sales price indicated on the commercial invoice.

The following types of cargo may have an invoice amount of zero, a nominal amount, or an amount different from the market value, so additional valuation documentation is required.

Type of Cargo	Issue with Invoice	Valuation Documentation to Confirm	Practical Handling
Free Samples	Declared as free or at a low value	Manufacturing cost, normal sales price, equivalent product price	Inquire with the insurer about a reasonable valuation method.
Free Supplied Goods	No sale price charged	Acquisition cost, book value, replacement cost	Confirm the owner and insurable interest.
Returned Goods	Original sales price differs from current value	Original invoice, reason for return, current condition	Specify if they are damaged or defective goods.
Repair Items	Only repair costs may be listed on the invoice	Item value, pre- and post-repair value, repair estimate	Confirm whether the item value needs to be included.
Exhibition Items	No sales price exists	Acquisition cost, market value, replacement cost	Specify usage history and condition.
Company-Owned Items	No external sales	Book value, replacement cost, appraisal report	Confirm if book value alone is sufficient.
Transfers Between Affiliated Companies	Transfer price may not reflect market value	Manufacturing cost, third-party sales price, appraisal data	Indicate if price is nominal.
Leased Items	Sales price may not correspond with ownership	Lease contract, acquisition cost, residual value	Confirm insured party and person with insurance claim rights.
Used Machinery	Sales price and replacement cost may differ significantly	Sales contract, market value, appraisal report, replacement estimate	Confirm necessity of agreed value or prior approval.
Replacement Items	No sales price due to free exchange	Normal sales price, manufacturing cost, exchange contract	Avoid mixing values of old and replacement items.

Setting the Sum Insured for Used Goods

For used goods, it is important to avoid declaring the sum insured based on the replacement cost of new items without supporting documentation or prior agreement with the insurance company.

However, using only the sales price for used goods is not always appropriate. If the sales price is nominal, it is difficult to reacquire equivalent items, or if repair or remanufacturing costs are necessary, additional documentation should be submitted to the insurer for inquiry.

The main documents to be confirmed include the following:

• Actual sales price
• Invoice amount
• Book value
• Market value in the used goods market
• Reacquisition cost of equivalent used items
• Repair or remanufacturing expenses
• Third-party appraisal report
• Agreed value
• Record of prior approval from the insurance company

Common Practical Cases

Case	Issue	Reference Documents	Key Points for Judgment	Initial Response

Freight Forwarder’s Scope of Involvement in Setting the Sum Insured

The five classifications in this article are not established by law or the industry at large but serve as an analytical framework used in this series to clarify the freight forwarder’s scope of involvement.

Even when a freight forwarder is involved in arranging cargo insurance, the authority related to insurance solicitation or contract conclusion should be confirmed separately from their status under the transport contract.

Standard Five Classifications	Main Involvement in Setting Sum Insured	Scope of Delegation to Confirm	Practical Notes
Simple Intermediary	Conveys the requested sum insured, trade term, and currency received from the cargo owner to the insurance agent	Whether only receiving and forwarding information or also requested to verify calculations	Does not necessarily guarantee that the sum insured is adequate.
Cargo Transportation Service Provider	Provides freight charges, transport segment details, and mode-of-transport information	Whether responsible for the insurance arrangement itself	Avoid confusing the provision of freight information with determination of the sum insured.
NVOCC / House B/L Issuer	Provides House B/L terms, ocean freight, transport section, and cargo information	Delegation scope regarding status as carrier and insurance arrangement	Being an NVOCC does not automatically grant authority to decide the sum insured.
Door-to-Door Single Contractor	Coordinates transport costs, insurance arrangements, and final declarations as an integrated service.	Cargo owner’s instructions, value calculation, subcontracting, and policy verification scope	Records the basis for the sum insured and the cargo owner’s approval.
Agent/Coordinator for Specific Operations	Coordinates insurance application, amount inquiries, document submission, or policy issuance	Specified tasks requested individually and approval authority	Does not unilaterally determine the sum insured beyond the delegated scope.

The terms Contracting Carrier and Actual Carrier represent legal or contractual statuses and do not substitute the standard five classifications used in this article.

Moreover, individual tasks such as providing freight details, verifying invoices, currency conversion, submitting insurance applications, or forwarding policies do not themselves constitute a sixth classification.

It is important that freight forwarders do not independently decide the sum insured but instead record instructions, invoices, sales terms, and responses from the cargo owner and insurance agent.

Common Misunderstandings

Misunderstanding	Actual Concept	Practical Notes
The sum insured is paid out as is in the event of a loss	The sum insured represents the maximum limit; the actual claim payment is calculated based on the loss amount, insurable value, and the applicable policy termss.	Distinguish between the sum insured and the assessed loss amount.
The sum insured and the insurable value are the same	The sum insured is the payment limit, while the insurable value is the value of the insurable interest.	Compare both when determining underinsurance or overinsurance.
Agreed value is just another name for the sum insured	The agreed value is the insurable value agreed upon by the contracting parties.	Confirm its relationship with the sum insured on the policy.
The invoice amount can be used directly as the sum insured	Depending on the trade term, the invoice amount may not include freight or premium.	Verify the trade term, freight charges, premium, and insurance percentage.
FOB value alone is sufficient	FOB value generally does not include ocean freight or insurance.	Check how to calculate the CIF equivalent value.
CIF × 110% is always mandatory	This is common practice, but it varies depending on the sales contract, Letter of Credit, and insurer conditions.	Individually verify the basis for this setting.
The insurance conditions for CIF and CIP are the same	The standard coverage levels and allowed transport modes under Incoterms differ.	Confirm CIF, CIP, and any additional terms in the sales contract.
A higher sum insured guarantees a higher claim payment	The excess portion is not automatically paid out as insurance proceeds.	Keep a reasonable rationale for the insurable value on record.
Underinsurance is only a problem in total loss cases	Depending on contract terms, it can also affect claims in partial loss cases.	Check the applicable policy termss and relationship with the insurable value.
Free goods should have the sum insured set to zero	Even without a sales price, there may be economic value or insurable interest.	Review manufacturing cost, replacement cost, or valuation data.
The exchange rate can be chosen arbitrarily by the person in charge	The exchange rate and date prescribed by the Open Cover Agreement or insurer should be used.	Record the basis for the currency conversion.
In Letter of Credit transactions, it’s sufficient if the insurance is correct	The insurance policy wording must also comply with the L/C conditions.	Verify amounts, currency, conditions, routing, and dates.

Practical Example 1: Calculating the CIF Equivalent from the FOB Value

For cargo with an FOB value of USD 100,000, the buyer requested arrangements for marine cargo insurance. However, the ocean freight had not been finalized at the time of booking, and only an estimated freight rate had been provided.

In this case, if the sum insured is set simply by applying 110% to the FOB value, the ocean freight and premium will not be reflected in the sum insured.

First, verify the applicable planned or estimated freight, other costs subject to insurance, and the insurance rate. Then, calculate the CIF equivalent and the sum insured using the method prescribed by the insurer or insurance agent.

If the finalized freight significantly differs from the planned amount, confirm whether a correction notice is required according to the Open Cover Agreement or individual policy.

Practical Example 2: Confirming the 110% L/C Requirement and the Policy Currency

In a transaction invoiced in euros, the letter of credit specified that the sum insured must be at least 110% of the invoice value and that the insurance policy should be issued in euros.

However, the insurance request only communicated the yen amount converted for internal management purposes to the insurance agent.

Even if an insurance contract based on the converted yen amount is not unreasonable coverage-wise, if the letter of credit requires a euro-denominated policy, this could cause a discrepancy in the documents submitted to the bank.

In such cases, the invoice value, the 110% amount, the currency specified by the L/C, the insurance terms, and the policy wording should be cross-checked before issuance. Confirmation with the bank and insurance agent should be obtained as necessary.

Practical Example 3: When the Valuation Basis for Used Machinery Is Insufficient

In a case involving the transfer of used machinery from an affiliated company, the invoice only stated a small amount as an internal transfer price.

Meanwhile, acquiring equivalent used machinery again on the market would require several times the invoice amount.

Setting the sum insured based solely on the invoice amount may result in insufficient coverage; however, using a new replacement cost without justification is also not appropriate.

Submit ledger values, used market prices, estimates for reacquiring equivalent items, the machinery’s condition, repair or rebuilding costs, and valuation reports, then inquire with the insurer about an agreed value or the need for individual approval.

Practical Example 4: When There Is No Invoice Value for Free-of-Charge Goods

For prototype samples provided free of charge to a customer, the Commercial Invoice for customs purposes stated “No Commercial Value.”

Even if no sale price is involved, there may be economic value in the cargo due to costs such as materials, processing, and design expenses incurred in manufacturing the prototype.

In such cases, rather than assuming that a zero invoice amount means that the cargo has no insurable value, supporting information such as manufacturing cost, reproduction cost, and the normal value of equivalent goods should be submitted to the insurer.

Development costs or intellectual property value should not be included without the insurer’s prior agreement. Supporting documents should be submitted and the valuation method confirmed with the insurer or insurance agent in advance.

Cases Requiring Prior Inquiry to the Insurer or Insurance Agent

In the following situations, do not handle the sum insured calculation simply by using CIF × 110%. Instead, consult with the insurance company or insurance agent in advance.

• When there is no invoice amount or if the amount is zero or nominal
• When dealing with used goods, high-value equipment, artworks, prototypes, etc., whose market value is difficult to determine
• When the purchase price and replacement cost differ significantly
• When the goods are free supplies, returned goods, repairs, or replacements
• When the DAP or DDP price includes customs duties, import taxes, installation charges, etc.
• When multiple currencies are covered under a single insurance policy or final declaration
• When the letter of credit requirements do not match the usual insurance terms
• When a insurance percentage different from the standard is desired
• When it is necessary to set an agreed value
• When quantity, unit price, freight, or route has changed after the insurance final declaration

Summary

The sum insured is the amount stated in the insurance contract as the maximum amount recoverable in respect of the insured cargo, subject to the applicable policy terms. It also serves as a basis for premium calculation.

The sum insured, insurable value, agreed value, CIF value, and premium are distinct concepts. The formula CIF × 110% is a common method for setting the sum insured, but it is not synonymous with the sum insured or the insurable value.

When setting the sum insured, it is necessary to check not only the invoice amount but also the contract price, freight, premium, insurance percentage, currency, exchange rate conversions, sales contracts, and letter of credit terms.

Under CIF and CIP Incoterms, the seller is generally responsible for arranging insurance; however, the applicable transport modes and standard coverage levels differ between CIF and CIP.

For FOB, CFR, or EXW terms, the CIF equivalent value must be calculated by adding freight, premium, and other costs. If the premium and sum insured are interrelated, the insurer’s specified calculation method should be used.

For free goods, used goods, repaired goods, company-owned property, or transfers between related companies, the invoice amount may not reflect the actual value. Supporting valuation documents should be submitted, and the valuation method should be confirmed with the insurer or insurance agent in advance.

If the sum insured is less than the insurable value or agreed value, the shortfall may limit recovery for a total loss and may also affect the calculation of a partial-loss claim, depending on the applicable policy terms. Conversely, setting an excessively high sum insured without reasonable grounds does not guarantee payment of the excess amount.

This article organizes common practical procedures for setting the sum insured in marine cargo insurance and does not determine the insurable value, agreed value, claim payment amount, letter of credit compliance, or legal responsibility for individual cases.

In actual practice, confirm the sum insured by reviewing the insurance policy, Open Cover Agreement, applicable policy termss, sales contracts, letters of credit, invoices, freight documents, valuation materials, and the insurer’s underwriting conditions. If necessary, consult the insurer or insurance agent in advance.
