Okla. Stat. tit. 12A, § 12A-2-319: F.O.B. and F.A.S. Terms

(1) Unless otherwise agreed the term F.O.B. (which means "free

on board") at a named place, even though used only in connection

with the stated price, is a delivery term under which

(a) when the term is F.O.B. the place of shipment, the

seller must at that place ship the goods in the manner provided in

this article (Section 2-504) and bear the expense and risk of

putting them into the possession of the carrier; or

(b) when the term is F.O.B. the place of destination, the

seller must at his own expense and risk transport the goods to that

place and there tender delivery of them in the manner provided in

this article (Section 2-503);

(c) when under either (a) or (b) the term is also F.O.B.

vessel, car or other vehicle, the seller must in addition at his own

expense and risk load the goods on board. If the term if F.O.B.

vessel the buyer must name the vessel and in an appropriate case the

seller must comply with the provisions of this article on the form

of bill of lading (Section 2-323).

(2) Unless otherwise agreed the term F.A.S. vessel (which

means "free alongside") at a named port, even though used only in

connection with the stated price, is a delivery term under which the

seller must

(a) at his own expense and risk deliver the goods

alongside the vessel in the manner usual in that port or on a dock

designated and provided by the buyer; and

(b) obtain and tender a receipt for the goods in exchange

for which the carrier is under a duty to issue a bill of lading.

(3) Unless otherwise agreed in any case falling within

subsection (1) (a) or (c) or subsection (2) the buyer must

seasonably give any needed instructions for making delivery,

including when the term is F.A.S. or F.O.B. the loading berth of the

vessel and in an appropriate case its name and sailing date. The

seller may treat the failure of needed instructions as a failure of

cooperation under this article (Section 2-311). He may also at his

option move the goods in any reasonable manner preparatory to

delivery or shipment.

(4) Under the term F.O.B. vessel or F.A.S. unless otherwise

agreed the buyer must make payment against tender of the required

documents and the seller may not tender nor the buyer demand

delivery of the goods in substitution for the documents.
