Ferrotungsten Low-Carbon Variant 65% W from Mexico
Low-carbon ferrotungsten with 65% tungsten and under 0.5% carbon, used in clean steel production for aerospace applications requiring high purity. Classified as ferrotungsten under HTS 7202.80.00.00, distinct from tool steels per U.S. Chapter 72 notes. Lumpy form prevents excessive gas evolution during melting.

Import Tips
• Certify carbon content below 0.5% with lab reports; distinguishes from high-carbon variants but remains 7202.80
• Ensure no heat-resisting steel elements per note (g); document iron-tungsten binary composition
