Cargo Insurance Calculator — Marine Freight Insurance Cost
Use our cargo insurance calculator to calculate cargo insurance premium for sea and air freight from China. Standard marine insurance covers CIF value + 10%.
Based on benchmark lane pricing, common port charges, and route assumptions rather than live carrier or forwarder quotes.
Freight moves quickly with seasonality, fuel, capacity, and route disruption. Treat these as planning benchmarks, not guaranteed quotes.

Medium SERP difficulty
Cargo insurance is the cheapest risk management tool available to importers — and the most commonly skipped. At 0.35–0.5% of the shipment value, the premium is far less than the deductible on any business insurance policy, yet it protects your entire inventory investment from origin factory to your warehouse door.
What Carrier Liability Actually Covers (Spoiler: Very Little)
Carriers are protected by international conventions that cap their liability far below actual cargo value:
| Convention | Applies To | Liability Limit per Package |
|---|---|---|
| COGSA (US sea freight) | US imports by sea | $500 per package |
| Hague-Visby Rules (UK/EU) | Most sea freight | SDR 666.67 per package |
| Montreal Convention | International air | SDR 22/kg actual weight |
| Road: CMR Convention | Truck transport | SDR 8.33/kg gross weight |
Real example: A $30,000 electronics shipment in 20 cartons. COGSA liability cap: 20 × $500 = $10,000. If the ship sinks, you recover $10,000 on a $30,000 loss — and that's before the carrier's lawyers argue "improper packing" to reduce it further.
Insurance Cost by Commodity and Coverage Level
| Commodity Type | ICC (C) | ICC (B) | ICC (A) |
|---|---|---|---|
| General manufactured goods | 0.20–0.30% | 0.25–0.40% | 0.35–0.55% |
| Electronics and tech goods | 0.30–0.50% | 0.40–0.65% | 0.50–0.80% |
| Furniture and wood goods | 0.20–0.35% | 0.25–0.45% | 0.35–0.60% |
| Glass, ceramics, fragile | 0.50–0.80% | 0.65–1.00% | 0.80–1.30% |
| Textiles and clothing | 0.20–0.35% | 0.25–0.40% | 0.30–0.50% |
| Machinery and equipment | 0.25–0.40% | 0.30–0.50% | 0.40–0.65% |
| Food and perishables | 0.60–1.00% | 0.80–1.30% | 1.00–1.80% |
Worked Example: $25,000 Shipment of Electronics
CIF value: $25,000
Coverage: ICC(A) at 0.60% of CIF + 10% uplift
Insured value = $25,000 × 1.10 = $27,500
Premium = $27,500 × 0.60% = $165
For $165, you protect $27,500 of electronics against:
- Total loss (shipment sunk, stolen, burned)
- Partial loss (water damage, container damage)
- General average (ship incident where all cargo owners share costs)
- Theft during transit
General average alone can cost thousands even if your cargo is undamaged — if the ship has a casualty, all cargo owners contribute proportionally. Without insurance, you pay this out of pocket and your cargo is held until payment.
Open Cargo Policy vs Per-Shipment Insurance
| Per-Shipment Coverage | Open Cargo Policy | |
|---|---|---|
| Cost | Higher per shipment | Lower (volume discount) |
| Flexibility | Cover only when needed | Automatic, all shipments |
| Administration | Arrange each shipment | Declare shipments periodically |
| Suitable for | <6 shipments/year | 6+ shipments/year |
| Typical threshold | Any volume | $500,000+/year insured value |
For importers doing 10+ shipments per year, an open cargo policy with a specialist marine insurer saves 20–40% vs per-shipment cover.
Tips for China Importers
- Get 3 freight forwarder quotes for every shipment. Rates for the same lane can vary 20–35% between forwarders. Never book with the first quote you receive.
- Know your LCL vs FCL crossover point. For most lanes, FCL 20ft becomes cheaper than LCL around 15 CBM. At 20+ CBM, FCL almost always wins on cost and transit time.
- Book 4–6 weeks ahead during peak season (July–October). Spot rates spike 30–50% during peak season. Pre-booking or securing a contract rate with your forwarder saves significantly.
- Negotiate free days at the destination port. Standard is 5 free days before demurrage kicks in. Push for 7 days — most forwarders will accommodate regular shippers.
- Always insure your cargo. Marine cargo insurance costs 0.3–0.5% of CIF value. One damaged container without insurance can wipe out months of profit. Never skip it.
