Six layers compose the Jan 1, 2027 mine-to-magnet prohibition. Each closes a loophole the prior layer left open.
Aug 13, 2018Established
NDAA FY2019 § 871 · Pub. L. 115-232[38]
Codified at 10 USC § 2533c (later renumbered § 4872). Prohibited DoD acquisition of select rare earth materials from covered nations.
Jan 1, 2021Expanded
NDAA FY2021 § 844 · Pub. L. 116-283[2][38]
Extended scope from raw oxides to finished NdFeB and SmCo permanent magnets.
Dec 22, 2023Defined
NDAA FY2024 § 854 · Pub. L. 118-31[3]
Redefined “melted or produced” to capture the full mine-to-magnet chain: mining, separation, refining, metallization, alloying, magnet manufacture. Sets the Jan 1, 2027 prohibition date.
Dec 23, 2024Funded
NDAA FY2025 · rare earth provisions[38]
Sustains DoD rare earth and magnet stockpile appropriations; preserves the § 854 timeline against deferral pressure.
Jul 10, 2025Incentivized
Rare Earth Magnet Security Act of 2025[2]
Domestic-content production tax credit for NdFeB magnets manufactured in the United States. Pulls commercial demand onto the same compliance chain.
Jan 1, 2027Enforced
DFARS 252.225-7052[3]
Procurement clause implementing § 854. Flows the prohibition down to every DoD prime and subcontractor on the effective date.
The mis-citation propagates across investor decks and equity research. REalloys’ Q1 2026 10-Q and downstream coverage cite the mine-to-magnet rule as “NDAA FY2023 § 857”. The operative section is § 854 of NDAA FY2024 (Pub. L. 118-31).
