# 12.209 Determination of price reasonableness.

While the contracting officer must establish price reasonableness in accordance with 13.106-3 , 14.408-2 , or subpart 15.4 , as applicable, the contracting officer should be aware of customary commercial terms and conditions when pricing commercial items. Commercial item prices are affected by factors that include, but are not limited to, speed of delivery, length and extent of warranty, limitations of seller’s liability, quantities ordered, length of the performance period, and specific performance requirements. The contracting officer must ensure that contract terms, conditions, and prices are commensurate with the Government’s need.
