Last updated: April 2026 dataCermets — composite materials combining ceramic compounds (typically carbides, nitrides, or oxides) with a metallic binder such as cobalt or nickel — are classified entirely under a single 10-digit line (8113000000) covering all forms including waste and scrap. Their primary commercial role is in cutting tools, wear-resistant components, and high-temperature structural parts for metalworking, mining, and aerospace industries. Germany leads US imports, consistent with its strong precision tooling and cemented carbide manufacturing base, followed by Canada and China. Imports from China may be subject to Section 232 or Section 301 tariff measures depending on the specific article form, and importers should confirm applicable trade-remedy exposure before entry.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Cemented carbides — such as tungsten carbide bonded with cobalt — are the most commercially significant type of cermet and are classified under heading 811300 when imported as articles. However, classification can be nuanced: certain carbide products may be classified under Chapter 82 (tools) or Chapter 84 (machinery parts) depending on their form and function. A licensed customs broker should review the specific article before entry.
Because all cermets — unwrought, wrought articles, waste, and scrap — share the single line 8113000000, mixed shipments of different cermet forms do not require line-by-line separation for tariff purposes. However, commercial invoices should still describe each form clearly to support accurate statistical reporting and to facilitate any end-use or trade-remedy review by CBP.
