50 U.S.C. § 98c — Materials constituting the National Defense Stockpile

(a) The stockpile is made up of ten categories of materials: (1) Materials already acquired under this subchapter and in the national stockpile on July 29, 1979. (2) Materials acquired under this subchapter after July 29, 1979. (3) Materials that were in the supplemental stockpile created by section 1704(b) of title 7 (which applied from September 21, 1959, through December 31, 1966) as of July 29, 1979. (4) Materials the United States acquired under section 4533 of this title and that the President transferred to the stockpile under that section. (5) Materials transferred to the United States under section 2423 of title 22 that were determined to be strategic and critical and that the President allocated for stockpiling. (6) Materials the Commodity Credit Corporation acquired and transferred to the stockpile under section 714b(h) of title 15. (7) Materials the Commodity Credit Corporation acquired under section 1743(a)(2) of title 7, and transferred to the stockpile as that section describes. (8) Materials the President transferred to the stockpile under section 1743(a)(4) of title 7. (9) Materials transferred to the stockpile under subsection (b) of this section. (10) Materials transferred to the stockpile under subsection (c) of this section. (b) Any material controlled by a federal department or agency must be transferred to the stockpile if three things are true: the department or agency head decides the material is excess to their needs, and the material is suitable for transfer or disposal through the stockpile. This transfer happens without reimbursing that department or agency — but the costs of making the transfer are paid or reimbursed from money appropriated for this subchapter. (c) The Secretary of Defense decides whether a material is suitable to be transferred to the stockpile under subsection (b), suitable to be disposed of through the stockpile, and free of contamination.
