Critical-mineral origin evidence
Prove where your tantalum and tungsten come from.
From January 1, 2027, defense contracts bar tantalum, tungsten and certain rare-earth magnets mined, refined, separated, melted or produced in China, Russia, North Korea or Iran.
CMMS-BS starts with what public disclosures establish: a published method and a benchmark of 128 company-mineral profiles, with full tantalum and tungsten assessments. Its governance protocol, which traces each production stage to a supplier's own documents, opens to clients when Highbrow Group begins commercial operations.
What changes in 2027
| Authority | Change | Timing |
|---|---|---|
| DFARS 252.225-7052 10 U.S.C. § 4872 | The restriction expands from material “melted or produced” in a covered country to material “mined, refined, separated, melted, or produced” there. | January 1, 2027 |
| Executive Order 14415, § 2 | Routine waivers under 10 U.S.C. 4872(c)(1) end, except under an accepted mitigation plan. | January 1, 2027 |
| Executive Order 14415, § 3 | Guidance requiring contractors at any tier to map supply chains “from raw materials to the end use products,” with an indentured bill of materials traced “back to the origin of raw materials.” | Due by January 16, 2027 |
Applicability, exceptions and implementation requirements are set out in the official texts.
How the governance protocol works
- 01Scope the question
Define the entity, product, mineral and period.
- 02Map every document
Match each source to the question it supports.
- 03Mark each stage
Evidenced, Unknown or Not applicable.
- 04Record the decision
Assign owners and explain the decision and its limits.
