Manufactured construction material.
(1) Manufactured construction material. The contracting officer must compare the offered price of the contract using foreign manufactured construction material (i.e., any construction material not manufactured in the United States, or construction material consisting predominantly of iron or steel and the iron or steel is not produced in the United States) to the estimated price if all domestic manufactured construction material were used. If use of domestic manufactured construction material would increase the overall offered price of the contract by more than 25 percent, then the contracting officer shall determine that the cost of the domestic manufactured construction material is unreasonable.
