A cermet is a sintered composite in which ceramic particles (such as tungsten carbide or titanium carbide) are dispersed throughout a metallic binder phase throughout the entire body of the material. A tool that is merely surface-coated with a ceramic or hard material remains classified as a metal tool. If the ceramic phase is integral to the bulk structure, the article belongs here under 8113; if it is only a surface treatment, classification follows the base material of the tool body.

Both finished articles and waste/scrap fall within heading 8113, so the same tariff line applies. However, scrap shipments may require additional documentation to confirm material composition and to satisfy any applicable Section 232 or antidumping review that attaches to the specific tariff line and country of origin. Consult a licensed customs broker to confirm the correct 10-digit classification and applicable trade-remedy exposure.
