Cargo and Inventory Insurance for Ecommerce
Why Carrier Liability Is Not Enough
When you ship goods by sea, air, truck, or rail, the carrier accepts some liability for the cargo they transport. But that liability is severely limited by international conventions and domestic regulations, and it almost never covers the full value of your shipment.
Ocean freight carrier liability is governed by the Carriage of Goods by Sea Act (COGSA) in the US, which limits the carrier's liability to $500 per package or customary freight unit. If your container holds 1,000 units of product worth $30 each, the total value is $30,000, but the carrier's maximum liability is $500 per package. How "package" is defined depends on how the bill of lading is written, and carriers write it to minimize their exposure. A full container might be treated as a single package, capping liability at $500 total for a $30,000 shipment.
Air freight carrier liability is governed by the Montreal Convention, which limits liability to approximately $24 per kilogram of cargo. A 500-kilogram shipment of electronics worth $100,000 would have a maximum carrier liability of about $12,000, leaving $88,000 uninsured.
Domestic trucking carrier liability is set by the Carmack Amendment, which generally makes the carrier liable for the full value of lost or damaged goods. However, many trucking companies include released value provisions in their contracts that limit liability to a stated amount per pound, often $0.50 to $2.00 per pound. A 1,000-pound pallet of goods worth $20,000 might have carrier liability limited to $500 to $2,000 under a released value provision.
In all cases, recovering from the carrier requires proving that the damage occurred while in the carrier's custody, that the goods were properly packaged, and that the loss was not caused by an act of God, war, or other excluded events. Carrier claims processes are slow, often taking 60 to 180 days for resolution, and disputed claims can take years. Cargo insurance provides a faster and more reliable path to recovery.
Types of Cargo Insurance Coverage
All-Risk Coverage
All-risk cargo insurance, also called "open perils" or Institute Cargo Clause A coverage, covers all causes of loss unless specifically excluded. This is the broadest and most common form of cargo insurance for ecommerce importers. Typical exclusions include loss due to inherent vice (the product deteriorating on its own), ordinary leakage, delay, willful misconduct, and war or strikes (which can be added back as separate endorsements).
All-risk coverage costs more than named perils coverage, typically 0.5% to 2% of the insured value, but the broader protection is worth the premium for most shipments. You do not need to prove what caused the loss, only that the loss occurred. This simplifies the claims process significantly compared to named perils coverage, where you must prove that the specific peril that caused the loss is listed on your policy.
Named Perils Coverage
Named perils coverage, also called Institute Cargo Clause B or C, only covers losses from specifically listed causes. Clause B covers risks like fire, explosion, vessel sinking, overturning of a vehicle, earthquake, volcanic eruption, and jettisoning of cargo. Clause C is even more restrictive, covering only major casualties like sinking, fire, and collision.
Named perils coverage is cheaper than all-risk, typically 0.3% to 1% of the insured value, but leaves gaps for common losses like theft, pilferage, and water damage that are not caused by the listed perils. For most ecommerce importers, the savings do not justify the coverage gaps, and all-risk is the better choice.
Warehouse-to-Warehouse Coverage
Warehouse-to-warehouse coverage protects your goods from the moment they leave the supplier's warehouse until they arrive at your warehouse. This includes loading, ground transportation to the port, ocean or air transit, customs clearance, ground transportation from the destination port, and unloading at your facility. Every handoff between vehicles, warehouses, and carriers is covered.
This is the most comprehensive transit coverage available and is standard on most all-risk cargo policies. Without warehouse-to-warehouse coverage, gaps can exist during inland transportation, warehousing at ports, and customs holding, which are often the stages where theft and damage are most likely to occur.
Inventory at Rest
Standard cargo insurance covers goods in transit. Once your inventory arrives at your warehouse, cargo insurance no longer applies. Protecting inventory at rest requires commercial property insurance, typically obtained through a business owners policy (BOP).
Some cargo policies include limited "stock throughput" coverage that extends protection to inventory while it is stored at your warehouse, in transit to customers, and at every point in between. Stock throughput policies are more expensive but eliminate the gaps between cargo insurance and property insurance, providing seamless coverage from the moment goods are manufactured until the moment they reach your customer.
How Much Cargo Insurance Costs
Cargo insurance premiums are calculated as a percentage of the insured value, which is typically the commercial invoice value plus freight costs plus a markup of 10% to 20% to cover incidental costs like duties, customs fees, and your expected profit margin.
Low-risk commodities (clothing, accessories, non-fragile household goods): 0.3% to 0.8% of insured value. A $25,000 shipment costs $75 to $200 to insure.
Moderate-risk commodities (electronics, glassware, furniture, packaged food): 0.8% to 1.5% of insured value. A $50,000 shipment of electronics costs $400 to $750 to insure.
High-risk commodities (fragile goods, high-theft items, temperature-sensitive products): 1.5% to 3% of insured value. A $30,000 shipment of fragile ceramics costs $450 to $900 to insure.
Per-shipment vs annual policies: If you import only a few shipments per year, per-shipment insurance purchased for each individual shipment is the simplest option. If you import regularly, an annual open cargo policy covers all shipments during the policy year up to a specified per-shipment limit, with annual premiums based on your estimated total import value. Annual policies typically offer lower per-dollar rates than individual shipment coverage because the insurer benefits from the volume commitment.
Filing Cargo Insurance Claims
When cargo arrives damaged or does not arrive at all, the claims process requires prompt action and thorough documentation.
Inspect immediately upon delivery. Check all packages and pallets for visible damage before signing the delivery receipt. If damage is visible, note it on the delivery receipt and take photographs. Signing a clean receipt, one with no damage noted, weakens your claim because the carrier and insurer can argue the damage occurred after delivery.
Document everything. Photograph all damaged goods, damaged packaging, and the overall condition of the shipment. Keep all packaging materials and damaged products until the claim is resolved. Maintain copies of the commercial invoice, packing list, bill of lading, delivery receipt, and any correspondence with the carrier about the damage.
Notify your insurer promptly. Most cargo policies require notification within a few days of discovering the loss or damage. Delayed notification can jeopardize your claim. Contact your insurer or broker as soon as you identify the issue and provide initial documentation.
File a formal claim. Your insurer will provide a claims form or online process. Submit the completed form along with the commercial invoice showing the value of the goods, the packing list showing what was in the shipment, photographs of the damage, the bill of lading and delivery receipt, and any correspondence with the carrier. The insurer reviews the documentation, may send a surveyor to inspect the damage for larger claims, and issues payment based on the insured value minus your deductible.
Typical resolution time: Cargo insurance claims are generally resolved within 30 to 60 days for straightforward cases with complete documentation. Complex claims involving partial damage, salvage value determinations, or disputes about the cause of loss can take longer. This is still significantly faster than carrier liability claims, which often take 90 to 180 days or more.
Incoterms and Insurance Responsibility
When you purchase goods from overseas suppliers, the trade terms (Incoterms) in your purchase agreement determine who is responsible for insuring the goods at each stage of transit.
FOB (Free on Board): The supplier is responsible for the goods until they are loaded onto the vessel at the origin port. Once on board, risk transfers to you. You are responsible for insuring the ocean transit and inland transportation to your warehouse. This is the most common Incoterm for ecommerce importers.
CIF (Cost, Insurance, and Freight): The supplier purchases cargo insurance for the ocean transit and includes it in the price. However, CIF insurance is typically minimum coverage (Institute Cargo Clause C, named perils only) at 110% of invoice value. Many importers purchase supplemental all-risk coverage on top of the supplier's CIF insurance to fill the coverage gaps.
EXW (Ex Works): Risk transfers to you the moment goods leave the supplier's factory. You are responsible for insuring the entire journey, including inland transport to the origin port, ocean transit, and inland transport to your warehouse. This gives you maximum control over the insurance coverage but also maximum responsibility.
DDP (Delivered Duty Paid): The supplier is responsible for the goods all the way to your warehouse, including customs clearance and duties. Risk stays with the supplier throughout, and they are responsible for insurance. However, if the supplier's coverage is inadequate, you bear the practical risk of lost inventory even though the legal risk lies with the supplier. Verifying that your supplier carries adequate cargo insurance under DDP terms protects your business interests.
Cargo Insurance vs Other Insurance Types
Cargo insurance covers goods in transit from supplier to your facility. Shipping insurance covers individual packages in transit from your facility to customers. Commercial property insurance covers inventory while it is stored at your location. These three coverage types work together to protect your inventory at every stage of the supply chain, but none of them can substitute for the others.
If you import a container of goods worth $40,000, store them in your warehouse, and ship them to customers in individual packages, you need cargo insurance for the inbound container, property insurance while the inventory is in your warehouse, and shipping insurance for the outbound customer packages. A gap in any one of these creates a period where your inventory is unprotected.
