Mine level
Ore concentrate
Tungsten ore concentrate from domestic and international mines, with the mine of origin recorded for each lot.
Tungsten recycling and supply
Tungsten with documented origin
Hamerdon is an American metals company starting in tungsten recycling. Hamerdon purchases tungsten scrap from US sources, including tungsten carbide, and supplies ore concentrate, APT and tungsten powder through a network of domestic and international suppliers. Each lot ships with origin and chain-of-custody documentation to support NDAA and DFARS compliance review.
Supply network
Supplier relationships at the mine, APT and powder stages
In addition to recycled scrap, Hamerdon sources material through domestic and international suppliers at three stages of production. Material from every stage is documented under the same lot record system.
Refining
APT
Ammonium paratungstate sourced from refiners with documented feedstock origin.
Powder
Tungsten powder
Tungsten metal powder for heavy alloy and carbide production, traceable through APT to the mine or scrap source.
Recovered scrap
Hamerdon recycling
Scrap purchased by Hamerdon is sent to processors as APT and powder feedstock and tracked under the same lot system.
Hamerdon does not source from China, Russia, North Korea or Iran, the covered nations under 10 U.S.C. 4872.

On January 1, 2027, the tungsten restriction extends to recycled material
The Department of Defense restricts the acquisition of tungsten from China, Russia, North Korea and Iran. The current restriction applies to melting and powder production. Effective January 1, 2027, it extends to the mining and production of tungsten ore and feedstock, including recycled material.
Covered material
Tungsten powder and heavy alloy
Tungsten metal powder, tungsten heavy alloy, and finished or semi-finished components that contain tungsten heavy alloy.
Covered nations
China, Russia, North Korea, Iran
The clause flows down to subcontracts for items containing covered material and applies to lower-tier suppliers as well as prime contractors.
From January 1, 2027
Scrap origin must be documented
Recycled feedstock comes into scope. Buyers will require documentation of where scrap originated as well as where it was melted. Hamerdon records scrap origin at the point of collection.
This summary is provided for general information and does not constitute legal advice. Requirements should be confirmed against the applicable contract clauses.
Suppliers and buyers

For suppliers and recyclers
Hamerdon is buying tungsten scrap
Hamerdon purchases scrap from recyclers, scrap dealers, machine shops, toolmakers and manufacturers. Tungsten carbide in all forms is a priority material. Each lot is reviewed for material and documentation, and terms are agreed before shipment.
Accepted material
- Tungsten carbide: inserts, end mills, drills, rods, blanks and dies
- Tungsten carbide wear parts, mining bits and saw tips
- Carbide grinding sludge, swarf and powders
- Tungsten heavy alloy: solids, offcuts, turnings
- Pure tungsten: wire, rod, sheet, electrodes
- Tungsten copper and other tungsten-bearing alloys
Mixed or unusual material is assessed case by case on receipt of a description.

Request supplyFor mines and producers
Concentrate with a documented route to US buyers
Hamerdon works with tungsten mines and developers outside China, Russia, North Korea and Iran to place concentrate with US processors. From January 1, 2027, DFARS 252.225-7052 also covers where tungsten is mined, so US defense supply chains will need a record that starts at the mine. We build that record lot by lot, from the mine gate to the buyer's receiving dock.
What we offer producers
- Offtake and sales of tungsten concentrate to US processors
- A record for every lot: origin, custody, assay and shipping documents
- Records structured to support DFARS 252.225-7052 review
- Offtake agreements for projects still in study, which lenders look for before they fund construction
