U.C.C. Sect. 2-512 Payment by Buyer Before Inspection

(1) Where the contract requires payment before inspection, nonconformity of the goods does not excuse the buyer from so making payment unless:

(a) the nonconformity appears without inspection; or

(b) despite tender of the required documents the circumstances would justify injunction against honor under the provisions of this Act (Section 5-114).

(2) Payment pursuant to subsection (1) does not constitute an acceptance of goods or impair the buyer's right to inspect or any of his remedies.
