In the Warehouse to Warehouse Clause, the insurance coverage commences from the time the goods leave the warehouse or place of storage at the place named in the policy, continues during the ordinary course of transit and terminates either on delivery

• to the consignee's or other final warehouse or place of storage at the destination named in the policy,
  
  
• to any other warehouse or place of storage, whether prior to or at the destination named in the policy, which the assured elect to use either for storage other than in the ordinary course of transit or for allocation or distribution,
  
  
• on the expiry of 60 days after completion of discharge overside from the overseas vessel at the final port of discharge (or the 30 days limit applies in the case of air freight),

whichever shall first occur.

In certain countries, the insurance company may have the marine extension clauses to override the main clauses, for example the Fifteen (15) Days Clause, in which the insurance coverage terminates on the expiry of 15 days after completion of discharge overside from the overseas vessel at the final port of discharge.

Under the American Institute Clauses, the number of days of the expiry of insurance coverage after completion of discharge overside from the overseas vessel at the final port of discharge is 15 days (or 30 days if the destination to which the goods are insured is outside the limits of the port)

The general guiding rate of the insurance premium is 1% of the amount insured. The premium rates may vary, for example, from 0.5% to 2.5% or more depending on factors such as:

In the trade contract terms FOB and CFR, the insurable interest transfers from the exporter to the importer at the time the goods pass over the ship's rail. It is very important that the exporter provides the details of the shipment to the importer promptly, so that the insurance can be arranged on time.

In practice, it is not uncommon that the importer arranges for insurance after the vessel has left the port of origin in the FOB and CFR terms. While it is the responsibility of the importer to arrange the insurance, the exporter may suffer loss if the goods are damaged before the insurable interest is transferred. As such, the exporter may insure the goods from the warehouse to the loading on board the vessel to overcome the contingency, without letting the importer know.

If the goods are exported on the open account basis where no letter of credit (L/C) is involved, there is a risk that the importer may reject the shipment if the goods are damaged on arrival. Contingency insurance may minimize the exporter's loss in such a circumstance. It is possible for the exporter to insure the goods from warehouse to warehouse. However, if the importer insures the goods too and claims the damage, the exporter cannot file for claims as he/she no longer has the insurable interest, and the exporter may not be able to provide the supporting insurance claim documents used by the importer to substantiate losses.

In the trade contract terms CIF and CIP, arrangement is usually made for any claims to be paid at destination to the consignee or issuing bank. However, should a loss occur prior to the passing of title to the goods to the consignee, such loss is payable at origin to the shipper or financing agent.

The assured is obligated in the policy to do everything to minimize the loss or damage, to file claims against the carrier or any other party who could be responsible for the loss or damage, and to notify the insurer or claim agent immediately of the loss or damage. The insurer or claim agent then appoints a marine surveyor (the adjuster) to inspect the subject matter insured and report on the cause of the loss or damage, the value of the cargo, and the extent of damage.

In some cases, the surveyor is named in the policy and the policy may require that request for survey to the surveyor or that claims against the carrier or any other party be made within a specified period of time after discharge of the goods from the vessel.

The surveyor issues a Certificate of Loss (Certificate of Survey), accompanied usually by the report of findings, to the consignee. The consignee may be required to pay a surveyor's fee, which may be refunded by the insurer or claim agent if the loss is recoverable under the policy.

When making an insurance claim, the claimant (the assured) usually is required to submit the following documents:

Subrogation

When the assured is fully paid in an insurance claim, he/she normally signs a subrogation form giving the insurer the rights to the lost or damaged cargo. It is only then the insurer may take actions against the carrier or any other party who could be responsible for the loss or damage.

While the payment in a particular average claim (either partial or total loss) usually is prompt, in a general average claim it may take many months. Referring to the general average sacrifice, the appointed marine surveyor (the adjuster) carefully calculates the value of each shipment---the wholesale price of each type of goods less the applicable customs duties, taxes and other charges---in proportion to the total value of the shipments and vessel.

Cargo owners whose goods are fully insured---the amount insured equals or exceeds the value of the goods---the insurers may put up immediately a general average guarantee to cover the contribution in the general average sacrifice, so that the cargo owners may obtain the goods from the carrier instead of waiting for many months for the settlement date. In some cases, the assured is required to post a general average bond in addition to the insurer's guarantee.

The insurers are liable for the cost of the claim in a general average claim as provided in all three basic types of policies in the old and the new Institute Cargo Clauses.

In the case of uninsured goods, the cargo owners must wait until the settlement date to obtain the goods from the carrier, unless the cash is put up to cover their shares of the contribution. Still, it may be weeks before the amount of the individual contribution is available.
