New Jersey § 12a:2-311

§ 12a:2-311.

(1) An agreement for sale which is otherwise sufficiently definite (subsection (3)

of 12A:2-204) to be a contract is not made invalid by the fact that it leaves particulars

of performance to be specified by one of the parties. Any such specification must be made in good faith and within limits set by commercial

reasonableness. (2) Unless otherwise agreed specifications relating to assortment of the goods are

at the buyer's option and except as otherwise provided in subsections (1)(c) and (3)

of 12A:2-319 specifications or arrangements relating to shipment are at the seller's

option. (3) Where such specification would materially affect the other party's performance

but is not seasonably made or where one party's cooperation is necessary to the agreed

performance of the other but is not seasonably forthcoming, the other party in addition

to all other remedies (a) is excused for any resulting delay in his own performance; and (b) may also either proceed to perform in any reasonable manner or after the time

for a material part of his own performance treat the failure to specify or to cooperate

as a breach by failure to deliver or accept the goods.
