From a full container to a single returned parcel, every leg of an import has an owner and a risk. A working guide to cargo cover for online retailers who import what they sell.
An online retailer importing stock lives a logistics life the insurance industry built its oldest products for — goods moving by sea, air and road, changing hands at ports and warehouses — usually without knowing it. Marine cargo insurance predates almost every other line, and it maps surprisingly well onto a modern e-commerce operation. The mapping just needs translating.
Start with the answer to the question importers actually ask: who pays if my goods are lost or damaged in transit? Not the shipping line, in any amount you would find satisfying. Carrier liability is limited by international conventions to amounts calculated per package or per kilogram — for a container of consumer electronics, often a small fraction of the goods' value — and it only applies at all if the carrier was at fault. Cargo insurance exists because carrier liability was never designed to make cargo owners whole.
First, know when the goods become your problem
Before insuring the journey, establish which parts of it are yours to insure. That is what Incoterms — the standard trade terms on your supplier contract — decide. Buy FOB and the goods are your risk from the moment they are loaded at the origin port, which means the ocean leg is yours to insure. Buy CIF and the seller arranges the ocean insurance — but read what they bought: CIF requires only minimum cover, often on restricted terms, ending at the destination port and leaving the truck leg to your warehouse bare. Buy DDP and the seller carries risk to your door, at a price that includes their insurance choices, not yours.
Many small importers do not know their own Incoterms. Find them on your supplier's proforma invoice before doing anything else in this guide.
Containers, pallets, parcels: three exposures, one policy
- The container. A full container load is the clean case: your goods, sealed at origin. The risks are the classics — water ingress, container loss overboard, theft, fire — plus one ancient rule covered below. Insure at landed cost plus a margin, commonly CIF value plus 10 percent, so a loss also covers the costs and profit already committed.
- The pallet. Most SME importers ship less-than-container-load, sharing a container with strangers' freight. Handling multiplies: your pallets are loaded, deconsolidated, restacked and cross-docked, and each touch is a damage opportunity. LCL claims are disproportionately about handling and water damage rather than dramatic marine events, which makes documentation at devanning — photos before you sign the delivery note — the habit that saves claims.
- The parcel. Direct-from-factory air parcels and customer returns travel under courier terms, where declared-value limits are low by default. For a steady flow of high-value parcels, insuring the flow under your own cargo policy usually beats paying the courier's per-parcel value surcharges — and covers the return leg, which courier cover often treats meanly.
General average: the old rule that still bites
Marine insurance carries one concept with no equivalent in any other line. When a ship's crew sacrifices cargo or incurs extraordinary costs to save the voyage — jettisoning containers, fighting a fire, hiring salvage tugs — the losses are shared by everyone with cargo on board, in proportion to its value. This is general average, it is centuries old, and it is very much alive: a single engine-room fire can trigger it on a ship carrying thousands of containers.
The practical meaning for an importer: your goods can arrive perfectly intact and still be held against a general average bond — a demand for security running to a meaningful percentage of their value — before release. A cargo policy responds by posting the guarantee and absorbing the contribution. An uninsured importer posts cash and waits, sometimes years, for the adjustment. Importers who insure only against damage to their own goods are missing the scenario where nothing of theirs was damaged at all.
One shipment or an open cover
Insuring shipment by shipment works for an occasional importer and quickly becomes an administrative tax on a regular one — every voyage a form, every form an opportunity to forget. The standing solution is an open cover: an annual arrangement that automatically insures every shipment within agreed limits and routes, settled by declaration. For a retailer importing monthly, an open cover converts insurance from a task per shipment into a line in the import cost model — and this automatic, per-shipment pattern is exactly the shape that lends itself to being embedded directly into freight-booking and logistics platforms, where the shipment data already exists.
The importer's checklist
- Confirm your Incoterms per supplier and mark where risk transfers to you.
- Insure landed cost plus margin, not bare invoice value.
- Check the policy covers warehouse-to-warehouse, including the final road leg and storage in transit.
- Ask how LCL and courier shipments are treated, and what the per-conveyance limits are.
- Understand your general average position — will the insurer post the bond?
- Photograph condition at devanning and claim within the policy's notice periods.
Cargo cover will not fix a supplier who ships badly packed goods — insurers exclude insufficient packing, and that dispute lands back on your purchase contract. What it fixes is everything between a good supplier and your warehouse door: the part of e-commerce that still runs on ships, weather and other people's cranes.
