The President shall prescribe such terms and conditions for the disposal of commodities in the commodity set-aside as he determines will provide adequate safeguards against interference with normal marketings of the supplies of such commodities outside the commodity set-aside. Strategic materials acquired by the Commodity Credit Corporation under paragraph (2) of this subsection shall be transferred to the National Defense Stockpile established by the Strategic and Critical Materials Stock Piling Act [
50 U.S.C.
98 et seq.], and the Commodity Credit Corporation shall be reimbursed for the value of the commodities bartered for such strategic materials from funds appropriated for purposes of that Act. For the purpose of such reimbursement, the value of any commodity so bartered shall be the lower of the domestic market price or the Commodity Credit Corporation’s investment therein as of the date of such barter, as determined by the Secretary of Agriculture.
