DFARS 252.225-7052 restricts defense programs from using tungsten metal powder or tungsten heavy alloy that was mined, refined, melted, or produced in China, Iran, North Korea, or Russia. Tungsten Parts Wyoming manufactures tungsten components in the United States, at our facility in Laramie, Wyoming, and we confirm DFARS 252.225-7052 sourcing compliance for your specific program and part. Talk to us before you spec.
What DFARS 252.225-7052 Requires
The clause covers tungsten metal powder and tungsten heavy alloy (WHA), plus any finished or semi-finished component containing them. Beginning January 1, 2027, contractors may not deliver covered material mined, refined, melted, or produced in a covered country (China, Iran, North Korea, Russia) under affected contracts. A supplier that cannot certify to 252.225-7052 is not fully DFARS compliant for those programs.
Why It Matters Now
Roughly 80% of the world’s tungsten is mined in China (U.S. Geological Survey), and most refined powder follows the same path. For defense and aerospace programs, that concentration is both a compliance problem and a supply-chain risk. A U.S. source removes the geopolitical exposure and simplifies the documentation a contracting officer will ask for.
