Marine Open Cover
One Agreement For Every Shipment You Make
A marine open cover is an annual agreement with an insurer that automatically protects every eligible shipment you make during the year, by sea, air, road or rail. Instead of buying a new policy each time goods move, you declare shipments as they happen and the insurer issues certificates against the cover. MILES sets up the terms, checks the limits against your real shipping pattern and stays with you when a consignment arrives damaged or short.

What A Marine Open Cover Gives You
Automatic Shipment Protection
Every shipment within the agreed scope is held covered from dispatch, subject to the declaration terms agreed with the insurer.
Certificates On Demand
Insurance certificates can be issued per consignment for banks, letters of credit and buyers who need proof of cover.
All Modes Of Transport
Sea, air, road, rail and courier movements can sit under one set of terms instead of separate policies.
Rates Fixed Upfront
Premium rates for each commodity and route are agreed at the start, so you can price your contracts with confidence.
Premium On Actual Shipments
A deposit premium is usually adjusted against declared values, so you pay for the trade you really do.
Claims Support From MILES
We help with survey requests, carrier notices and document lists so a transit claim is not delayed by missing papers.
What is a marine open cover?
A marine open cover is a long-term agreement, usually for twelve months, under which an insurer agrees in advance to insure all shipments of specified goods on specified routes. You declare each shipment, and the insurer issues a certificate or accepts the declaration against the agreed rates and conditions.
It suits businesses that import or export regularly and cannot afford a gap in cover because someone forgot to buy a policy before a container sailed. The open cover is the contract; the individual certificates are the evidence of cover for each consignment. Some insurers issue a marine open policy with a fixed sum insured that reduces with each declaration, while an open cover has no overall ceiling beyond the agreed limits per shipment. Your broker should explain which structure you are being offered.
What a marine open cover protects
The scope depends on the clauses chosen. For international voyages, Indian insurers commonly use the Institute Cargo Clauses:
- ICC (A) — the widest, all-risks style cover, subject to named exclusions.
- ICC (B) — named perils such as fire, stranding, collision, jettison, washing overboard and entry of sea or river water.
- ICC (C) — a narrower set of major casualties, often used for bulk cargo.
War and strikes, riots and civil commotion risks are added through separate Institute clauses. Domestic legs inside India are usually covered under Inland Transit Clauses, which also come in wider and narrower forms. A well-built open cover can also include warehouse-to-warehouse transit, storage at intermediate points and the inland leg before or after the voyage.
What is usually not covered
- Loss caused by insufficient or unsuitable packing.
- Ordinary leakage, loss in weight and normal wear and tear.
- Delay, even when caused by an insured peril, and resulting loss of market.
- Inherent vice — the goods spoiling because of their own nature.
- Wilful misconduct of the insured, and shipments not declared honestly.
Who needs a marine open cover?
Importers of raw material, exporters shipping to regular buyers, trading houses and manufacturers with steady cross-border movement all benefit. The deciding factor is frequency. If you ship more than a handful of consignments a year, an open cover is normally cheaper to administer than buying single transit policies one by one, and it removes the risk of an uninsured sailing. Your Incoterms matter too: under FOB or CFR purchases, the buyer carries the transit risk and must arrange insurance; under CIF sales, the seller does.
How the premium and limits are set
Underwriters look at the commodity, packing, voyage, mode of transport, vessel type, destination risk and past claims. Key terms to agree before inception are:
| Term | What it means for you |
|---|---|
| Basis of valuation | Often invoice value plus freight, with an agreed uplift for expected profit. The uplift varies by insurer and contract. |
| Limit per bottom or conveyance | The most the insurer will pay for goods on one vessel, aircraft or truck. |
| Location limit | The maximum exposure while goods sit at a port, warehouse or transit point. |
| Declaration terms | Whether you declare each shipment or send a monthly or quarterly schedule. |
| Deposit premium | Paid upfront and adjusted against the declared values at the end of the period. |
If your largest shipments regularly exceed the per-conveyance limit, those consignments may be underinsured. That is one of the most common gaps we find when we review existing covers.
How MILES helps
- We compare insurers for your commodity and lanes, including rates, deductibles and how each one handles surveys at foreign ports.
- We check the clauses: ICC (A) versus (B), war and strikes, inland extensions, storage periods and the valuation clause.
- We size the limits against your real shipment data so the per-conveyance and location limits match your biggest movements.
- We set up declarations in a format your logistics team can maintain without errors.
- We support claims, from the first survey request to the final settlement. See our claims support page for how we work.
How a claim works
- Note any visible damage or shortage on the delivery receipt before signing it clean.
- Inform the insurer and MILES at once, and request a survey. Keep the goods and packing for inspection.
- Serve a written notice of claim on the carrier, port or airline within the time limits in their terms. This protects the insurer’s recovery rights.
- Collect the invoice, packing list, bill of lading or airway bill, certificate of insurance, survey report and carrier correspondence.
- Submit the claim bill. The insurer assesses it against the clauses and the declared value, and settles.
A marine open cover sits alongside other options under our marine insurance range. Manufacturers who move most goods by road within India often prefer a marine sales turnover policy, while an occasional shipper may only need single transit marine insurance.
Cover, exclusions and premiums depend on the insurer’s policy wording and underwriting. MILES Insurance Brokers Pvt. Ltd. is an IRDAI-licensed direct broker (Life & General, Reg. No. 954); the insurance is issued by the insurer. Insurance is the subject matter of solicitation.
