If you've ever signed a purchase order with a factory in Shenzhen or Ho Chi Minh City, you've seen "FOB" stamped on it. FOB shipping is one of the most widely used terms in international trade, but most Ecommerce founders treat it as boilerplate. That's a mistake. The FOB clause determines who pays for freight, who carries the risk if a container falls off a ship, and where your landed cost calculation actually begins. Get it wrong, and you're either underestimating your true cost of goods or absorbing liabilities you never agreed to.
This page breaks down what FOB shipping means, the difference between FOB Origin and FOB Destination, how it compares to other Incoterms like EXW and DDP, and why FOB matters more than ever for brands manufacturing in Asia.
FOB stands for "free on board." The International Chamber of Commerce defines it as one of 11 Incoterms — standardized trade terms that allocate responsibilities between buyer and seller for international shipments.
Under a FOB agreement, the seller is responsible for the goods up to a specific point in the journey. After that point, the buyer takes over. The "point" is what changes based on the variant:
FOB technically applies to sea and inland waterway freight. For air or ground shipments, FCA (Free Carrier) is the correct term under Incoterms 2020 — though in practice, many brands and suppliers still use "FOB" loosely across modes.
The distinction matters because it changes who pays and who's liable when something goes wrong.
FOB Origin (FOB Shipping Point)
FOB Destination
If you're buying from a factory in China and the PO says "FOB Shenzhen," you're on the hook for ocean freight, insurance, customs clearance, and any damage from the moment the container is loaded. The factory's job ends at the port.
FOB is one of several Incoterms you'll encounter. Each shifts the responsibility line:
For most DTC brands sourcing from Asia, FOB is the default. But it pushes a lot of complexity downstream onto the buyer — booking freight forwarders, paying duties, coordinating customs, and managing 3PL receiving. That's where the legacy model breaks down.
FOB is the starting line for landed cost calculations. Your factory's FOB price covers the product itself plus loading at the origin port. From there, you're adding:
Brands that quote margins off the FOB price alone consistently underestimate true unit economics. Two products with identical FOB prices can have wildly different landed costs depending on weight, dimensions, HS code, and routing.
U.S. Customs uses transaction value — typically the FOB price you pay your supplier — as the primary basis for customs valuation. This is the dutiable amount, not your retail price.
Declaring retail price instead of FOB price is one of the most expensive valuation mistakes brands make. A product with a $6.45 FOB cost and a $32 retail price faces duty on $6.45, not $32. Getting this right protects margin and keeps you compliant with CBP's "reasonable care" standard.
In the legacy model, FOB Origin terms set up a long, expensive chain: factory → port of origin → ocean freight (3–6 weeks) → port of entry → drayage → domestic 3PL → pick and pack → last-mile carrier → customer. Each handoff adds time, cost, and risk. You pay duties on the entire container upfront, store inventory for months, and only start collecting cash when products finally sell.
That model was built for a world of large bulk shipments and predictable demand. It's a poor fit for Ecommerce brands trying to test SKUs, respond to demand signals, and protect cash flow.
Portless doesn't eliminate FOB — your factory still sells to you on FOB terms. What changes is what happens next. Instead of booking ocean freight, paying duties on a full container, and waiting weeks for goods to land at a domestic 3PL, your inventory moves directly into our factory-adjacent fulfillment center in Asia. From there, individual orders ship directly to your customers in five to eight days, with duties paid per order under a DDP model — not on unsold inventory sitting in a warehouse.
The result: faster cash conversion, lower inventory risk, and no capital locked up in a warehouse betting on a demand forecast. If you want to model the impact on your own numbers, run the math through our direct fulfillment ROI calculator or contact us to talk through your supply chain.
