Stock Throughput Insurance

Stock throughput insurance is a specialty policy that follows a business’s goods across the entire supply chain, from the factory or port to third-party warehouses to the customer, under one program. It may cover inventory in transit and in storage, including at third-party logistics sites, closing gaps that standard property or a warehouse’s own policy often leaves.

If your products move through a supply chain, from the factory or port to a third-party warehouse to your customer, your inventory is exposed at every step. We help California importers, distributors, and product businesses close the gaps most owners do not know they have.

What does stock throughput insurance cover?

  • Goods in transit by sea, air, and land, including import and export shipments.
  • Inventory stored at your locations and at third-party sites, including third-party logistics (3PL) warehouses and fulfillment centers.
  • Raw materials, work in process, and finished goods across the supply chain.
  • Often broader valuation, such as selling price rather than cost.
  • Catastrophe perils on stored stock, subject to terms.

Who needs it? Importers and exporters moving goods internationally; businesses that store inventory at 3PL, fulfillment, or public warehouses; distributors, wholesalers, and product or e-commerce companies with inventory spread across multiple locations; and manufacturers with raw materials and finished goods moving through a supply chain.

Many owners assume the inventory sitting in a third-party logistics or fulfillment warehouse is covered by the facility’s insurance. Often it is not. A 3PL’s property policy covers the building and the 3PL’s own property, not your goods, and most 3PL contracts limit or cap their liability. Stock throughput covers your goods directly, regardless of who is at fault. California’s ports make import, export, and 3PL storage central to many local businesses.

How we help: We map where your goods originate, travel, and rest, review your 3PL and warehouse contracts for liability limits and carveouts, and structure a stock throughput program so your inventory is covered end to end.

My inventory is stored at a third-party warehouse. Is it covered by the warehouse’s insurance?2026-08-13T00:14:31-07:00

Only where the warehouse is legally liable, which generally means the loss traced back to a failure to exercise reasonable care. Storage agreements also commonly cap what the warehouse owes, sometimes to a set amount per pound. A stock throughput policy covers your goods on your own terms, in storage and in transit, rather than leaving the outcome to someone else’s liability and contract limits.

Does it cover imported goods before they reach me?2026-08-10T13:45:51-07:00

Often yes, including ocean and air transit and storage along the way, subject to policy terms.

Can it cover catastrophe perils at a warehouse?2026-08-10T13:45:52-07:00

It can be structured to, subject to terms and limits, which is valuable where standard property sublimits are low.

Isn’t my inventory covered by the 3PL’s insurance?2026-08-10T13:45:53-07:00

Usually not fully. A 3PL’s coverage protects its building and its own property, and its legal-liability or bailee coverage generally responds only when the 3PL is at fault, often capped by contract. Stock throughput covers your goods directly.

How is this different from cargo or inland marine?2026-08-10T13:45:53-07:00

Cargo covers goods in transit and inland marine covers certain moving or off-site property; stock throughput combines transit and storage across the whole supply chain in one policy, often with fewer gaps.
