Nonagglomerated Metal Carbides Mixed with Metallic Binders imports of $9.3M in April 2026 ran 15% above the year-to-date monthly average of $8.1M.
Last updated: April 2026 dataNonagglomerated metal carbide powders — most commonly tungsten carbide, titanium carbide, or tantalum carbide — blended with metallic binders such as cobalt or nickel are critical precursor materials for cemented carbide tooling, wear parts, and hard-metal components. Unlike sintered (agglomerated) carbide articles, these mixed powders remain in loose or slurried form, placing them in heading 382430 rather than in the tool or article chapters. Canada and Finland are the leading US suppliers, with Germany and Austria also significant, reflecting the concentration of hard-metal industry expertise in those countries.

Heading 382430 applies to mixed carbide powders or slurries that have not yet been pressed and sintered into a defined shape. Once the material is compacted and sintered — even into a blank or preform — it typically moves to Chapter 82 (tools) or Chapter 84/85 (machine parts), depending on the article's form and function. The agglomeration state at the time of importation is the decisive factor.
Importers should monitor whether specific carbide powder blends from particular origins are subject to antidumping or countervailing duty orders, as the hard-metal sector has historically attracted trade remedy investigations. A licensed customs broker or trade attorney can confirm current order scope before entry.
