FOB costs split cleanly at one point: the ship’s deck. Under an FOB (Free On Board) quote, the seller pays for everything needed to produce the goods, move them to the named port of shipment, clear them for export, and load them onto the vessel. From the moment the cargo is on board, the buyer owes ocean freight, marine insurance, destination port charges, import duties, and inland delivery. The FOB price is the seller’s number; the buyer’s true cost keeps climbing after that.
Where the Cost Line Falls
Under Incoterms 2020, FOB applies only to goods shipped by sea or inland waterway. It cannot be used for air freight, rail, or truck-only shipments, which fall under Free Carrier (FCA) instead.1International Trade Administration. Know Your Incoterms
The transfer point is the moment the goods are placed on board the vessel at the named port. When a price is quoted as “FOB Port of Charleston,” the seller’s financial and risk obligations end once the cargo is on the ship at that port. Risk of loss or damage during the ocean voyage belongs to the buyer from that point forward.2International Chamber of Commerce. Incoterms 2020
What the Seller’s FOB Price Includes
The FOB price is more than the cost of the product. It rolls in every expense the seller bears to get the goods from the factory floor to the ship’s deck:
- Production or acquisition cost of the finished goods.
- Export packaging and preparation, including crating, palletizing, labeling, marking, and any quality testing needed to meet export standards.
- Inland freight to the port, including fuel surcharges and tolls on trucking or rail.
- Export customs clearance, including export documentation, any export duties or government fees, and required licenses.
- Origin terminal handling charges for receiving, moving, and staging the container within the port facility.
- Physically lifting the cargo onto the vessel.
One documentation cost worth flagging inside export clearance: the old paper Shipper’s Export Declaration has been replaced by Electronic Export Information (EEI), filed through the Automated Export System (AES). EEI filing is mandatory for most shipments valued over $2,500 per commodity classification, shipments requiring an export license, and shipments to certain embargoed destinations.3International Trade Administration. Filing Your Export Shipments through the Automated Export System (AES) The seller handles this filing, and the cost is baked into the FOB price.
What the Buyer Pays After Loading
Once the goods are on board, every dollar spent from that point is the buyer’s. Together these costs make up what accountants call landed cost.
Ocean Freight and Surcharges
The biggest post-FOB expense is the main ocean freight charge. Carriers rarely bill a flat rate. On top of base freight, buyers can expect fuel-related surcharges (often called a Bunker Adjustment Factor), currency adjustment factors, peak season surcharges, and various ancillary fees that vary by carrier and trade lane. These surcharges shift substantially from quarter to quarter, so a freight quote from three months ago may bear little resemblance to the rate at booking.
Marine Insurance
Because risk transfers at loading, the buyer needs marine cargo insurance for the voyage. Coverage comes in three standard tiers under the Institute Cargo Clauses: Clause C is the narrowest (major casualties like fire, sinking, and collision), Clause B adds weather-related perils, and Clause A is all-risk coverage against theft, breakage, shortage, and most other losses not specifically excluded. Buyers purchasing under FOB terms choose their own coverage level, and experienced importers almost always opt for Clause A.2International Chamber of Commerce. Incoterms 2020
Destination Port Charges
At the destination port, the buyer pays terminal handling charges for unloading the container and moving it through the facility. These are separate from the ocean freight bill and are assessed by the terminal operator. If the buyer doesn’t pick up the container within the allotted free time, demurrage fees (for occupying port space) and detention fees (for holding the container itself outside the terminal) start accruing. At major U.S. ports, these penalties can exceed $400 per container per day, and they add up fast during congestion or customs holds.
Import Customs Clearance and Duties
The buyer handles all import customs procedures. The importer of record must file entry documentation with U.S. Customs and Border Protection (CBP), declaring the value, classification, and applicable duty rate for each item.4Office of the Law Revision Counsel. 19 USC 1484 Entry of Merchandise The duty rate depends on how the goods are classified under the Harmonized Tariff Schedule.5U.S. Customs and Border Protection. Determining Duty Rates
The value CBP uses to calculate duties is called transaction value. It starts with the price actually paid or payable for the goods (the FOB price, in most cases) and adds certain adjustments like packing costs borne by the buyer, selling commissions, royalties, and the value of any materials or tools the buyer supplied to help produce the goods.6Office of the Law Revision Counsel. 19 USC 1401a Valuation of Imported Merchandise
Inland Delivery
The final leg from the destination port to the buyer’s warehouse rounds out the landed cost. This includes trucking or rail fees, chassis rental charges, and any tolls. For buyers located far from a port, this last stretch can be a surprisingly large portion of total freight cost.
Compliance Costs That Can Blindside Either Side
FOB transactions carry filing obligations that, if missed, result in fines and cargo delays. These costs aren’t in the FOB price, but they hit the buyer directly.
Importer Security Filing
For ocean shipments headed to the United States, the buyer (or their customs broker) must submit an Importer Security Filing, commonly called the ISF or “10+2,” at least 24 hours before the cargo is loaded onto the vessel at origin. CBP can assess liquidated damages of $5,000 per violation for a late, incomplete, or inaccurate filing.7U.S. Customs and Border Protection. Importer Security Filing and Additional Carrier Requirements A missing ISF can also hold the shipment at the port until CBP reviews the documentation, which means demurrage stacking on top of the penalty.
Misclassification and Valuation Errors
If CBP determines that goods were negligently misclassified or undervalued, the penalty can reach the lesser of the domestic value of the merchandise or two times the duties the government was shorted. When the error didn’t affect the duty amount, the cap drops to 20 percent of the dutiable value.8Office of the Law Revision Counsel. 19 USC 1592 Penalties for Fraud, Gross Negligence, and Negligence These are maximums for negligence; fraud carries steeper consequences.
How FOB Changes the Accounting on Both Sides
The FOB term controls when both parties record the transaction. Getting the timing wrong can misstate revenue, inventory, and taxable income.
Seller’s Revenue Recognition
Under ASC 606, a seller recognizes revenue when control of the goods transfers to the customer. For international FOB shipments, control typically transfers when the goods are loaded onto the vessel at the named port. One SEC filing described the point as “the completion of loading the material at the point of origin,” because that was when the customer obtained legal title and the ability to direct use of the goods.9Securities and Exchange Commission. Summary of Significant Accounting Policies The distinction matters for quarterly reporting, especially for companies shipping high-value goods near the end of a fiscal period.
Buyer’s Inventory and Landed Cost
On the buyer’s side, the goods become an inventory asset on the balance sheet at the same moment risk transfers. But the value recorded isn’t just the FOB price. Under GAAP inventory costing rules, the buyer capitalizes all costs necessary to bring the inventory to its present condition and location. That means the FOB price, ocean freight, marine insurance, non-recoverable import duties and tariffs, and inland delivery costs all get added to the asset’s value rather than being immediately expensed. The total is the landed cost, and it eventually flows through cost of goods sold when the inventory is used or resold.
Recovering Duties Through Drawback
Buyers who import goods under FOB terms and later re-export them, either in the same condition or after incorporating them into a manufactured product, may be eligible for a duty drawback refund of up to 99 percent of the duties, taxes, and fees originally paid.10Office of the Law Revision Counsel. 19 USC 1313 Drawback and Refunds Claims can reach back five years from the date of importation.
The program covers standard import duties, Section 301 duties, and merchandise processing fees, among others. Section 232 duties on steel and aluminum are excluded by presidential proclamation, and antidumping or countervailing duties are excluded by statute. For importers dealing in high-duty goods that eventually leave the country, drawback can recover a meaningful portion of the landed cost.
Domestic FOB Is Not the Same Term
One boundary worth flagging: the term FOB means something different in domestic U.S. shipping than in international trade. Under the Uniform Commercial Code, “FOB shipping point” (or FOB origin) means the buyer takes ownership and risk when goods leave the seller’s location, and “FOB destination” means the seller retains risk until the goods arrive at the buyer’s door. These domestic terms can apply to any mode of transport and involve a transfer of title.11Legal Information Institute. Uniform Commercial Code 2-319 FOB and FAS Terms
International FOB under Incoterms 2020 works differently. It applies only to sea and inland waterway transport, specifies a named port of loading as the transfer point, and defines only the transfer of risk and cost, not title or ownership, which remain governed by the sales contract.1International Trade Administration. Know Your Incoterms Contracts should specify which one applies.
How FOB Costs Compare to CIF and FCA
Two other trade terms come up constantly, and the cost differences shape which term makes sense for a given shipment.
Under CIF (Cost, Insurance, and Freight), the seller pays for ocean freight and arranges minimum insurance (Institute Cargo Clauses C) to the named destination port.2International Chamber of Commerce. Incoterms 2020 The seller’s quoted price is higher than FOB because it bundles freight and insurance. Even so, risk of loss still transfers to the buyer at the origin port on loading, identical to FOB. Many buyers prefer FOB precisely because it lets them choose their own freight forwarder and insurance coverage rather than accepting whatever the seller arranged.
FCA (Free Carrier) works with any mode of transport, making it the alternative when goods move by air, rail, or truck.1International Trade Administration. Know Your Incoterms The transfer point under FCA is earlier in the supply chain. When delivery happens at the seller’s premises, the seller’s obligation ends once the goods are loaded onto the buyer’s transport vehicle. When delivery happens at another named location, the seller delivers once the goods arrive there ready for the carrier. The buyer takes on cost and risk well before the goods reach a port, which is why the FCA price is typically lower than the FOB price for the same goods.
