Products classified under Tariff item 8101.10
Atomized Tungsten Powder
Gas-atomized tungsten powder with controlled spherical morphology, used in powder metallurgy and thermal spraying. It is a powder form of tungsten, not an alloy or article, and therefore falls under tariff item 8101.10.00.
8101.10.00Micron Tungsten Powder 5-10um
Fine 5-10 micron tungsten powder for injection molding of complex parts. This is a tungsten powder product, not an alloy or article, so it is classified under tariff item 8101.10.00.
8101.10.00Nano Tungsten Powder
Nanoparticle tungsten powder (<100nm) for catalysts, batteries, and advanced materials research. As a tungsten powder, it falls under tariff item 8101.10.00 regardless of particle size.
8101.10.00Pure Tungsten Powder 99.9%
High-purity tungsten powder (≥99.9% W) used in metallurgy, electronics, and 3D printing. It is a pure tungsten powder, not an alloy or article, so it falls under tariff item 8101.10.00.
8101.10.00Reduced Tungsten Powder
Hydrogen-reduced tungsten powder from ammonium paratungstate, standard for powder metallurgy parts. This is an intermediate tungsten powder product, falling under tariff item 8101.10.00.
8101.10.00Tungsten Carbide Powder
Tungsten carbide powder, composed primarily of tungsten carbide (WC), used in cutting tools and wear-resistant parts. Although it contains carbon, it is a tungsten powder and falls under tariff item 8101.10.00 as a powder of tungsten.
8101.10.00Tungsten Powder for 3D Printing
Spherical tungsten powder optimized for selective laser melting (SLM) in additive manufacturing of high-density parts. It is a tungsten powder, not an alloy or article, so it falls under tariff item 8101.10.00.
8101.10.00Tungsten Powder for Catalysts
Activated tungsten powder used as a hydrogenation catalyst precursor in the chemical industry. As a pure metal powder, it falls under tariff item 8101.10.00.
8101.10.00Tungsten Powder for Electronics
Ultra-pure tungsten powder for semiconductor contacts and thick-film pastes. With purity >99.999%, it is a tungsten powder and falls under tariff item 8101.10.00.
8101.10.00Tungsten Powder for Lamp Filaments
High-purity, coarse tungsten powder for drawing into lamp filament wire. It is a powder form of tungsten, not yet an article, so it falls under tariff item 8101.10.00.
8101.10.00Tungsten Powder for Welding Electrodes
Lanthanum-doped tungsten powder for TIG welding electrode production. Although doped, it remains a tungsten powder and falls under tariff item 8101.10.00, as it is not a final article.
