You're looking at a shipping invoice. There it is. FOB. It sounds like a secret handshake between salty sea captains and logistics nerds. Honestly, it kind of is.
If you’ve ever bought something from a wholesaler or tried to move a container across an ocean, you’ve run into this. It stands for Free on Board. Simple, right? Not really. People mess this up constantly. They lose thousands of dollars because they thought "FOB" meant one thing when the contract meant another. It’s the oldest trick in the international trade book, and if you don't get the nuance, you're the one paying for the sunken cargo.
What FOB actually means when the rubber hits the road
At its core, FOB is an Incoterm. These are rules set by the International Chamber of Commerce (ICC). Basically, it’s a universal language so a guy in Shanghai and a woman in Chicago don't have to argue about who pays the insurance if a wave eats a crate of electronics.
FOB tells you exactly where the seller’s responsibility ends and the buyer’s headache begins.

It defines the "transfer of risk." Imagine a literal line on the deck of a ship. Once that box crosses the rail, the seller is off the hook. If the ship sinks five minutes later? That’s the buyer's problem. If the crane drops the box before it hits the deck? That’s on the seller. It sounds petty, but in a multi-million dollar shipment, those three feet of air space matter.
The big divide: FOB Shipping Point vs. FOB Destination
This is where the real money is lost. Most people think FOB is just one thing. It's not. It’s a fork in the road.
FOB Shipping Point (sometimes called FOB Origin) means the buyer takes ownership the second the goods leave the seller's dock. You bought it? It’s yours now. You pay for the freight. You pay for the insurance. If a truck driver has a bad day and flips the rig on the highway, you—the buyer—are the one filing the insurance claim. Sellers love this. It gets the liability off their books fast.
Then there is FOB Destination. This is the buyer’s best friend. Here, the seller owns the goods all the way until they arrive at your front door (or warehouse). They pay the freight. They take the risk. If the goods show up smashed, you just point at the pile of junk and say, "Try again."
Why does this matter for your taxes? Because of "title transfer." If you use FOB Shipping Point, those goods are technically your "inventory" the moment they leave the factory. If it's December 31st and your goods are on a boat in the middle of the Pacific, they show up on your year-end balance sheet.
The 2020 Incoterms update and the "Maritime Only" rule
Here is something most "experts" get wrong.
According to the ICC Incoterms 2020 rules, FOB is technically only supposed to be used for sea and inland waterway transport. If you are shipping via air, rail, or truck, you aren't supposed to use FOB. You're supposed to use FCA (Free Carrier).
Does anyone actually follow this? Hardly.
Most businesses are lazy. They’ve used "FOB" for decades for everything from Fedex envelopes to 747 cargo planes. But here’s the danger: if you use FOB for an air shipment and something goes wrong, a savvy insurance lawyer could argue the contract is invalid because the term was used incorrectly.
Who pays for what? Let's be specific
Let’s break down the money. If you are the buyer in a standard FOB Shipping Point deal, you are cutting checks for:
- The ocean freight or trucking costs.
- Marine insurance (highly recommended, don't be cheap here).
- Unloading fees at the port.
- Customs duties and taxes.
- The "last mile" delivery to your warehouse.
The seller just has to get the goods to the port, clear them for export, and make sure they get onto the vessel. That’s it. They’re done. They can go have a drink while you sweat the storms.
Common mistakes that will kill your margins
I've seen companies go under because they didn't specify the "named place." You can't just write "FOB" on a contract. You have to write "FOB [Named Port/Location]".
If you write "FOB Long Beach," but the goods are coming from Vietnam, you’ve just created a legal nightmare. Who pays for the trans-Pacific leg? If the contract is vague, the courts usually side with whoever has the better lawyers.
Another huge mistake? Ignoring "Loading Costs." Under FOB, the seller pays to get the cargo on the ship. But sometimes ports have "terminal handling charges" that are separate from the actual loading. If your contract doesn't specify who covers the THC (Terminal Handling Charge), you’ll be arguing over a $500 bill while your cargo sits in the sun.
Why big retailers obsess over FOB
Look at a giant like Walmart or Amazon. They almost always insist on FOB Origin.
Why? Because they have massive logistics arms. They can ship a container for half the price a small manufacturer can. By taking control of the shipping (FOB Origin), they save millions on freight markups that sellers usually tack on. If you let a seller handle the shipping (FOB Destination), they are going to charge you a "convenience fee" hidden in the freight cost.
However, if you're a small business starting out, FOB Origin is terrifying. You don't have a logistics team. You don't know how to talk to a freight forwarder in Ningbo. In that case, paying the premium for FOB Destination is basically paying for peace of mind.
The "Over the Rail" myth
Old-school shipping guys still talk about the "ship's rail." There was an old rule that risk transferred the exact moment the goods passed over the physical railing of the ship.
The ICC actually did away with this "imaginary vertical line" concept in the 2010 and 2020 updates. Now, the rule is simpler: risk transfers when the goods are "on board" the vessel. It sounds like the same thing, but it’s more about the goods being safely stowed rather than just dangling from a crane over the deck.
Actionable steps for your next shipment
Don't just sign the invoice. Do these three things right now:
- Check the location. If it says "FOB Factory," you are responsible for everything from the moment it hits the loading dock. If you aren't prepared to hire a trucking company in a foreign country, stop right there and renegotiate.
- Verify your insurance. Most standard business insurance does not cover goods in transit across an ocean. If you are buying FOB Shipping Point, you need to buy a separate marine cargo policy. It’s usually cheap—maybe 0.5% of the cargo value—but it saves you from total ruin.
- Specify the version. Write "Incoterms 2020" in your contracts. There are still people using the 1990 or 2000 versions, and the rules on who pays for security-related clearances have changed. Being specific prevents the "well, that's not how we used to do it" argument.
Is FOB right for you?
Honestly, it depends on how much control you want.
If you want the lowest price and you're willing to handle the logistics, go with FOB Shipping Point. You'll get the raw price of the goods and you can hunt for the cheapest shipping rates yourself.
If you are busy and just want the stuff to show up so you can sell it, demand FOB Destination. You'll pay more for the goods, but you won't lose sleep over a container ship getting stuck in the Suez Canal. That becomes the seller's heart attack, not yours.
Stop treating those three letters as boilerplate text. They are the difference between a profitable quarter and a massive insurance claim. Specify the port, pick your version of the rules, and always, always know exactly when that "risk" slides from the seller's hands into yours.
Next Steps for Implementation:
- Review your current vendor contracts to see if "FOB" is followed by a specific location.
- Contact a freight forwarder to get a quote on an "FOB Origin" shipment to compare it against what your supplier is currently charging you for "Delivered" pricing.
- Update your purchase order templates to include the phrase "per Incoterms 2020" to ensure modern legal protections apply to your trades.
