Cargo insurance for an ocean or air shipment is usually priced as a small percentage of the insured value, not as a flat fee. The examples below use rates of 0.10%, 0.30% and 0.60% to show the calculation; these are illustrations, not current offers or a guaranteed market range. A binding quote depends on the goods, route, packing and policy terms. Below, you'll see how the premium is calculated, a worked example, and what pushes your quote up or down.
Key points
- Use quoted rates to calculate the premium; allow for minimum premiums and any cargo, route or war-risk charges.
- Confirm the policy valuation basis. A common illustration is invoice plus freight and agreed expenses, with a 10% uplift; it is not a universal formula.
- Premium = insured value × rate. At $0.65 per $100, a $59,400 insured value costs $386.10.
- Commodity type, lane, deductible, coverage limit and claims history move the price most.
- A cheap quote with the wrong exclusions can cost you the claim, so compare coverage before price.
What cargo insurance cost looks like in practice
Start with the insurer’s rate and valuation basis. Marine cargo cover is often priced as a percentage of insured value, subject to minimum premiums, deductibles and any additional charges. Higher-risk commodities or routes can attract different terms or require separate approval.

The source graphic illustrates rate bands; it is not a current insurance quote. Confirm rates and coverage with the insurer for your shipment.
Two sellers shipping the same dollar value can receive different quotes because the goods, route and policy terms differ. Do not apply trucking cargo-liability rates to an importer’s marine cargo policy; they cover different interests.
Here is how that range translates into dollars on a typical seller shipment. These figures use hypothetical rates to illustrate the arithmetic, not quotes:
| Insured value | At 0.10% | At 0.30% | At 0.60% |
|---|---|---|---|
| $10,000 | $10.00 | $30.00 | $60.00 |
| $24,750 | $24.75 | $74.25 | $148.50 |
| $59,400 | $59.40 | $178.20 | $356.40 |
The middle row comes from the worked example below. Real quotes also carry minimum premiums, so a very small shipment can cost more than the percentage alone suggests.
How the premium is calculated
The calculation has two steps: build the insured value, then apply the rate.
Step 1: build the insured value
Insuring only the invoice can leave freight and other agreed expenses outside the valuation. A professional cargo insurance guide from a trade association calculates insured value by adding freight and other expenses to the commercial invoice value, then adding 10%. A second industry guide gives the same simple method and warns that focusing only on invoice value leaves shippers exposed in a claim, because the real financial stake includes freight charges and additional expenses.
Why it matters: if your goods are lost and you only insured the invoice, the insured amount may be lower than your total exposure. Any payment remains subject to the policy, deductible and covered cause of loss.

Step 2: apply the rate
Multiply the insured value by the combined cargo and war rates, then divide by 100 when the rate is quoted per $100. The same trade guide works an example: goods worth $50,000 plus $4,000 in freight and other expenses give an insured value of $59,400. At $0.65 per $100, the premium is $386.10.
A seller-sized example
Say you are importing a $20,000 order of kitchen products with $2,500 in freight and charges.
- Invoice $20,000 + freight and charges $2,500 = $22,500.
- Add 10%: $22,500 × 1.10 = $24,750 insured value.
- At 0.30%: $24,750 × 0.003 = $74.25.
- At 0.10%, the premium is $24.75. At 0.60%, it is $148.50.
At those illustrative rates, this $20,000 order produces premiums of about $25 to $150 before minimums or additional charges. Ask for a written quote; the example is not a promised price.
What moves your price up or down
Seven factors show up again and again in insurer guidance.
- Commodity type. Insurers underwrite the goods, how susceptible they are to loss, damage or theft, and how they are packed and shipped, per the trade guide. Fragility and theft exposure can change underwriting terms.
- Lane and route risk. Trade areas are part of underwriting. The rate depends on lane risk, commodity, deductible and loss history, according to this pricing guide.
- Deductible. A cargo coverage guide notes that accepting a higher deductible may reduce a quoted premium.
- Coverage limit. The same guide notes that higher coverage limits raise premiums.
- Claims history. A clean record helps, and a string of claims does the opposite.
- Cargo value. More insured value means a larger premium at the same rate.
- Add-ons. War-risk and similar charges are added to the base rate, as the rate guide explains.

Why the carrier's liability does not replace insurance
A common assumption is that the carrier pays if something goes wrong. Carrier liability is a different thing from insurance. A suitable cargo policy can cover the agreed transit from pickup to delivery, subject to its terms. Carrier liability instead depends on the applicable transport contract, defenses and legal limits. Carrier liability is also limited by the terms of the contract and the rules that apply to the mode of transport, so it rarely matches the value of a full inventory shipment.
For an Amazon seller, the practical point is simple. A missing or damaged pallet means a stockout, a delayed FBA check-in and lost sales during the weeks you can least afford them. Cargo insurance can reimburse covered physical loss or damage; it does not normally reimburse stockout losses, lost sales or delay alone. For a plain-language overview of what a policy covers, see our guide on what cargo insurance is and the U.S. guide to shipping insurance.
Exclusions: the part of the quote that decides the claim
Price only tells half the story. Common exclusions can include delay, inherent vice and inadequate packing. Nuclear, war, strikes and cyber risks may be excluded or addressed by separate clauses or endorsements. Read the actual policy and transit limits rather than assuming every insurer uses the same exclusions. See the cargo insurance guide for examples.
A practical way to sanity-check quotes is to collect a low, a typical and a high estimate, as this pricing guide suggests, because a cheap policy with the wrong exclusions can end in a denied claim. When you read a quote, check three things:
- Is it all-risk or named perils? Our comparison of all-risk and total-loss cover shows why this matters for small sellers.
- Does the agreed insured value include freight, expenses and any uplift required by the policy or sales contract?
- What deductible applies, and where does cover start and end?
If you are buying on CIF terms from a Chinese supplier, the policy attached to the sale may be thinner than you assume. This breakdown of CIF risks and exclusions is worth reading before you accept it. For more on how quotes are structured, see this explanation of how to get and read a shipping insurance quote.
What to have ready before you ask for a quote
Quotes come back faster and more accurately when you bring the right details. For a one-off shipment, have these ready:
- A description of the goods and how they are packed
- Commercial invoice value, freight cost and other charges
- Origin, destination and mode (ocean, air or express)
- Any claims history
If you ship regularly and want a policy that covers many shipments, the trade guide says to provide a goods description, your top five trade regions, the valuation basis and the estimated annual insured shipment values. One point there matters for growing sellers: gross sales do not necessarily equal insured exposure. Premiums should reflect the estimated insured value of your annual shipments, not your revenue, a view also made in an insurer presentation to the marine insurance union.
How to keep the cost sensible without cutting protection
The aim is a lower rate for the same real cover, never thinner cover.
- Pack to the standard insurers expect. Poor packaging is a standard exclusion, so good packing protects both the goods and the claim.
- Pick a deductible you can absorb. A higher deductible lowers the premium, as noted in the coverage guide. Set it at an amount your cash flow can handle on a bad day.
- Insure the right value. Confirm the agreed valuation basis, including freight and any uplift. Payment is subject to insured perils, limits and deductibles.
- Bundle with one workflow. Insurance bought together with the shipment, customs and delivery is easier to document than a policy bought separately. Our guide to avoiding freight forwarder hidden fees shows how to read every line on a forwarder quote.
- Know the claim process before you need it. Keep the invoice, packing list, bill of lading and photos. Our freight insurance claim guide walks through it, and the coverage examples for e-commerce sellers show how it plays out.
Perspective
Most small sellers we talk to treat insurance as the line item to trim. We see it the other way around. A proportionate premium can protect against covered physical loss or damage to inventory, subject to policy limits and exclusions.
That is why we build cargo insurance into the same workflow as customs, duties and delivery. When one team handles pickup, DDP clearance, FBA labeling and cover, there is one set of documents and one account manager to call if something goes wrong. Our goal is for a seller to know the full cost before the goods leave China, with scope, exclusions and possible additional charges recorded in the quote.
If you are just starting out, begin with the insured value. Confirm freight, expenses and any agreed uplift, ask what all-risk terms actually cover, and read the exclusions before the price. Do that and the quote becomes easy to compare.
Get cargo cover as part of your shipment
If you are moving inventory from China or Korea to the US, we can include cargo insurance with the rest of the job: pickup, customs clearance, duties and delivery to the fulfillment center in one workflow. Each shipment has a dedicated account manager, and you can ask for the insurance terms alongside the freight quote. See our Amazon FBA freight forwarding from China, our DDP shipping to the USA or the small seller FBA freight page to start.

FAQ
How much is cargo insurance for a typical shipment?
Using illustrative rates of 0.10% to 0.60%, a $24,750 insured value produces premiums of roughly $25 to $150. Actual rates, minimum premiums and additional charges require an insurer’s quote.
Is cargo insurance based on the invoice value only?
No. A common example uses invoice plus freight and agreed expenses, then a 10% uplift, as described in a trade association guide. The policy and sales contract determine the actual valuation basis; insuring only the invoice can leave expenses outside the insured value.
Why do two quotes for the same goods differ so much?
Commodity, lane, deductible, coverage limit and claims history all affect the rate, according to a cargo insurance pricing guide. Exclusions differ too, so compare what is covered as well as the price.
Does carrier liability cover my shipment?
Carrier liability is subject to transport-contract and legal limits. A suitable cargo policy can cover agreed transit risks beyond those limits, as this coverage comparison explains. Confirm the covered journey, exclusions and deductible.
What lowers my cargo insurance cost?
A higher deductible, solid packing, a clean claims record and accurate shipment details all help. The coverage guide notes that higher deductibles reduce premiums while higher limits increase them.
