Definition
Free on board (commonly abbreviated F.O.B.) is a commercial shipping term specifying the point at which a seller's delivery obligation is fulfilled and the buyer assumes responsibility for goods in transit. When a contract designates goods as sold "free on board," the seller must deliver the goods to the named location or carrier — typically a ship, railcar, or other conveyance — at the seller's expense and without additional charges to the buyer for packing, cartage, portage, or similar handling costs. Once delivery to the designated point is made, risk of loss and further freight costs pass to the buyer.
The term operates primarily as a risk-allocation and cost-allocation device. Two dimensions are always at issue: (1) who pays the freight and handling costs up to a given point, and (2) at what moment title and risk of loss shift from seller to buyer.
Modern commercial law in the United States, specifically UCC Article 2, defines F.O.B. as a delivery term and distinguishes between F.O.B. place of shipment (risk passes when goods are delivered to carrier at origin) and F.O.B. place of destination (risk passes only when goods arrive at the named destination). The UCC also recognizes F.O.B. vessel, requiring the seller to load goods on board at the named port.

Common Language
Modern common usage (Wiktionary): Without charge to the purchaser for delivery on board a carrier (originally a ship), at a specified location or point.
Historical common usage (Webster's 1913): Not included in Webster's 1913 — the phrase was trade and commercial jargon rather than ordinary vocabulary.
The common definition accurately captures the cost-allocation aspect of F.O.B. but omits the term's critical legal dimension: risk of loss. In everyday commercial language, "free on board" tends to be understood only as a shipping cost arrangement. Legally, the F.O.B. designation also determines the precise moment at which risk of damage or destruction shifts from seller to buyer — a distinction with major consequences when goods are lost or damaged in transit and insurance or litigation follows.

Common Confusion
F.O.B. is frequently confused with C.I.F. (cost, insurance, and freight) and C.&F. (cost and freight), which are destination-oriented shipping terms under which the seller arranges and pays for ocean freight and, in the case of C.I.F., insurance. Under F.O.B. terms, the buyer typically arranges onward freight after the delivery point; under C.I.F. or C.&F., the seller does so. Researchers encountering historic commercial contracts should not assume these terms are interchangeable — the risk and cost allocations differ substantially, and courts have consistently treated them as distinct legal obligations.
F.O.B. is also sometimes conflated with F.A.S. (free alongside ship), which requires delivery alongside the vessel rather than on board it. The distinction determines whether loading costs fall on the buyer or seller.

Why It Matters in Research
F.O.B. is one of the most litigated shipping terms in commercial history, and its legal meaning has shifted meaningfully across eras and legal regimes.
Pre-UCC sources — including the historical dictionary entries below — describe F.O.B. in terms of delivery to the vessel or railcar without expense to the buyer, but say relatively little about title passage or risk of loss, which were governed by common law sale-of-goods rules and varied by jurisdiction. Researchers using pre-UCC cases or treatises should not import modern UCC risk-of-loss analysis backward onto those sources.
The Uniform Sales Act (1906, adopted in many states) and then UCC Article 2 (widely adopted from the 1950s onward) progressively systematized F.O.B. terminology. UCC § 2-319 provided the definitive modern framework until the 2003 revisions deleted § 2-319 from the updated Article 2 (though those revisions were not widely adopted). This creates a layered research problem: the controlling definition of F.O.B. in a given dispute depends on which version of the UCC — or which pre-Code law — applied in that jurisdiction at the relevant time.
International contexts add further complexity. Incoterms, maintained by the International Chamber of Commerce, define F.O.B. for international sales differently than the UCC does for domestic sales. In Incoterms, F.O.B. applies specifically to sea and inland waterway transport; the UCC definition historically applied to any carrier. Researchers encountering international commercial disputes should verify whether the contract incorporated Incoterms or domestic UCC definitions.
Historical Pennsylvania cases — including Dwight v. Eckert, cited in the early editions of Black's — established the rule that a seller under an F.O.B. vessel contract need not act until the buyer names the receiving vessel. This rule survives in principle into the UCC era but is not always made explicit in later cases or commercial practice. Researchers tracing the doctrine's development should note this Pennsylvania origin.
The abbreviation F.O.B. appears in primary sources with and without periods. Early court records and shipping contracts may use "f.o.b.," "F.O.B.," or "free on board" interchangeably. Corpus searches should account for all variants.

Historical Dictionary Support
All three historical sources — Black's (both editions) and Bouvier's — are in close agreement on the core definition: F.O.B. means the seller delivers goods to the designated carrier without packing, cartage, portage, or similar charges falling on the buyer. All three also reproduce the same doctrinal point drawn from Dwight v. Eckert: the seller's duty to perform is contingent on the buyer naming the ship.
The uniformity across sources reflects how settled the basic concept was by the late nineteenth century. However, the historical entries are conspicuously silent on several matters that later became the primary locus of F.O.B. litigation: title passage, risk of loss, and insurance obligations. These issues were handled by background common law rules on passage of title in sales contracts, not by the F.O.B. term itself. Researchers relying on the historical dictionaries for F.O.B. doctrine will find them adequate for the delivery and cost questions but incomplete for the risk-allocation questions that dominate modern commercial disputes.
Bouvier's cross-references "Frais jusqu'à bord" — the French equivalent, meaning "costs to the ship's side" — which is useful context for researchers working in Louisiana law or admiralty sources influenced by French commercial practice.
Neither historical source addresses railroad or overland freight contexts systematically, though the phrase "cars, vessel, etc." in both editions of Black's signals awareness that the term extended beyond maritime shipping even in the nineteenth century.

Jurisdictional Note
In the United States, F.O.B. is governed by UCC Article 2 for domestic commercial sales, subject to the version adopted in each state. Louisiana, which has not adopted UCC Article 2, applies its own Civil Code rules on sales, and researchers should treat F.O.B. in Louisiana commercial contracts with care. For international sales, Incoterms govern if incorporated by contract, and their definition of F.O.B. diverges from the UCC in scope and risk-transfer rules.
