3PL & Warehouse Insurance for Ecommerce Sellers

What your 3PL's policy actually covers

• ✗ Damage caused by 3PL negligence (forklift accident, mishandling, racking failure)
• ✗ Limited warehousemen's legal liability subject to contract caps
• ✗ Operational errors like incorrect labeling or fulfillment mistakes
• ✗ Coverage limited to what is specified in your warehouse agreement

What you still need to insure yourself

• ✓ Acts of God (fire, flood, hurricane, earthquake) — never covered by 3PL
• ✓ Theft from break-ins, employee theft, mysterious disappearance
• ✓ Goods in transit between facilities, ports, or to your customer
• ✓ Contingent coverage if your 3PL goes out of business or insurance lapses
• ✓ Full replacement value at YOUR cost basis, not the 3PL's contractual cap

The forklift accident

3PL operator pierces a pallet of supplements with a forklift. The 3PL pays for the damaged pallet under their warehousemen's legal liability — but only up to their per-pallet contract cap, often a fraction of your wholesale value.

The roof leak

Storm hits, roof leaks overnight, and 50 SKUs of inventory are water damaged. This is an "act of God" exclusion in nearly every 3PL policy. Without your own inland marine policy, you eat the loss.

The 3PL closure

Your 3PL files for bankruptcy. Their insurance lapses. Your inventory is locked up while creditors sort through the assets. Contingent coverage on your end is the only thing that protects you.

The transit gap

Inventory moves from manufacturer in China to LA port to your 3PL. Damage occurs at the port. Neither carrier nor 3PL covers it. You need cargo / inland marine.

The Amazon FBA + 3PL split

Half your SKUs ship to FBA, half to a 3PL. FBA reimburses at their price (not yours). The 3PL caps liability. Inventory insurance fills both gaps.

The fulfillment error

3PL ships the wrong product to a customer who has an allergic reaction. Your product liability and the 3PL's legal liability both engage — and you need both.

3PL & Warehouse Insurance FAQ

Does my 3PL's insurance cover my full inventory?

No. A 3PL's warehousemen's legal liability covers their responsibility for damages they cause through negligence, not the full replacement value of your goods. Acts of God, theft, and many other losses fall outside their coverage. You need your own inland marine or commercial property policy that specifically extends to third-party storage locations.

What is warehousemen's legal liability?

Warehousemen's legal liability requires the 3PL to provide "reasonable care" for goods in its custody. If the 3PL's negligence causes loss or damage, their insurer covers losses up to a contractually agreed limit. The key word is negligence — accidents, weather, theft by third parties, and equipment failure not caused by negligence are typically excluded.

What does 3PL insurance NOT cover?

Acts of God (fire, flood, hurricane, earthquake), theft by third parties, mysterious disappearance, damage during transit between facilities, losses exceeding the contractual liability cap, and any losses where negligence cannot be proven. Standard policies also exclude high value items, hazardous materials, and certain product categories without specific endorsements.

Do I need separate inventory insurance if I use FBA and a 3PL?

Yes. FBA reimburses at Amazon's determined value, not your cost basis or replacement cost — and only for items lost or damaged inside Amazon's facilities. A 3PL covers only their negligence. Inventory insurance from your own policy fills both gaps and covers transit between locations.

What about goods in transit between my manufacturer and the 3PL?

Standard commercial property policies typically cover inventory only at named locations. Goods in transit need cargo insurance (ocean marine for international, inland marine for domestic). This is one of the most common coverage gaps we see.

How much does inventory and 3PL coverage cost ecommerce sellers?

Inland marine premiums typically run around 0.5 percent of the insured value of goods. Combined ecommerce policies covering inventory, general liability, and product liability typically run $500 to $2,000 per year for small to mid sized sellers, depending on revenue, product category, and claim history.

What insurance does Amazon require for sellers using 3PLs?

Amazon requires $1 million per occurrence and $1 million aggregate of commercial general liability insurance once a seller's gross proceeds exceed $10,000 in any month. Amazon must be named as an additional insured. The 3PL's policy does not satisfy this requirement — it must be your own policy.
