S. 5330: Critical Mineral and Extraction Tax Parity Act

This bill would change a federal tax credit for domestic critical mineral production. In simple terms, it would make more types of mineral production eligible for the credit, allow more mining-related costs to count toward the credit, and remove a special limit that currently lowers the credit for metallurgical coal.

What the bill changes

• Adds more minerals to the tax credit list. The bill expands the list of “critical minerals” eligible for the advanced manufacturing production tax credit to include:
  • Boron
  • Copper
  • Lead
  • Potash
  • Rhenium
  • Silicon
  • Silver
  • Uranium
  • Phosphate, but only in certain processed forms, such as phosphoric acid, high-purity phosphorus, or purified phosphate rock suitable for making phosphoric acid
• Lets some ore extraction costs count toward the credit. If a taxpayer extracts ore that is later refined into an eligible critical mineral, the bill would allow certain extraction costs to be treated as qualifying costs for the credit, as long as the refiner certifies that:
  • the ore was refined into an applicable critical mineral, and
  • the refiner sold that mineral to an unrelated buyer as part of its business.
• Limits which foreign extractions qualify. The extraction-cost change would only apply if the ore was:
  • extracted in the United States, or
  • extracted outside the United States only when the mineral type is not mined in commercial quantities in the U.S. and the ore did not come from a “foreign country of concern.”
• Prevents double counting. The bill directs the Treasury Department to write rules so the same extraction costs are not counted more than once in the credit system.
• Removes a special reduction for metallurgical coal. The bill would repeal the current rule that cuts the credit amount for metallurgical coal to 2.5 percent, meaning metallurgical coal would no longer get that reduced rate under this provision.

When it would take effect

• The added minerals would apply to minerals produced and sold after December 31, 2025.
• The extraction-cost rule would apply to costs incurred after December 31, 2025.
• The metallurgical coal change would also apply to minerals produced and sold after December 31, 2025.

Practical effect

The bill would likely make the tax credit more valuable for companies involved in mining, refining, or processing the newly covered minerals in the United States. It could also benefit some producers of metallurgical coal by restoring the full credit rate instead of the reduced one. The bill does not directly create a new program; it changes how an existing tax credit works.

Relevant Companies

• FCX — Freeport-McMoRan could be affected because it is a major U.S. copper producer, and copper would be added to the list of eligible minerals.
• SCCO — Southern Copper could be affected through its copper mining and processing operations, though the extent would depend on which production qualifies under the credit rules.
• TECK — Teck Resources has copper and metallurgical coal operations; the bill could affect qualifying U.S. mineral production and the metallurgical coal credit rate.
• MP — MP Materials could be indirectly affected if downstream critical mineral processing and related credit rules influence domestic supply chains, although rare earths are not newly added here.
• CVX — Chevron could see indirect effects through mineral and energy-related supply chains, but any direct impact would likely be limited unless it has qualifying mineral operations.
• BHP — BHP’s U.S. copper and potash-related interests could be affected if its production or processing qualifies for the expanded credit.
• VII — Vectura? None found
