Okla. Stat. tit. 12A, § 12A-2-513: Buyer's Right to Inspection of Goods

(1) Unless otherwise agreed and subject to subsection (3),

where goods are tendered or delivered or identified to the contract

for sale, the buyer has a right before payment or acceptance to

inspect them at any reasonable place and time and in any reasonable

manner. When the seller is required or authorized to send the goods

to the buyer, the inspection may be after their arrival.

(2) Expenses of inspection must be borne by the buyer but may

be recovered from the seller if the goods do not conform and are

rejected.

(3) Unless otherwise agreed and subject to the provisions of

this article on C.I.F. contracts (subsection (3) of Section 2-321),

the buyer is not entitled to inspect the goods before payment of the

price when the contract provides

(a) for delivery "C.O.D." or on other like terms; or

(b) for payment against documents of title, except where

such payment is due only after the goods are to become available for

inspection.

(4) A place or method of inspection fixed by the parties is

presumed to be exclusive but unless otherwise expressly agreed it

does not postpone identification or shift the place for delivery or

for passing the risk of loss. If compliance becomes impossible,

inspection shall be as provided in this section unless the place or

method fixed was clearly intended as an indispensable condition

failure of which avoids the contract.
