Certain categories of carbide cutting tools and inserts from China have been subject to antidumping duty orders, and Chinese-origin cutting tools broadly face Section 301 tariff exposure. Importers should check the current scope of any active antidumping orders with the Commerce Department's Enforcement and Compliance database and confirm the applicable HTS classification before entry, as scope determinations can be product-specific.

The HTS distinguishes cutting tools primarily by the material of the cutting part: high-speed steel tools, cemented carbide (tungsten carbide) tools, and diamond or cubic boron nitride tools each fall under different subheadings within Chapter 82 or 84. Coatings (e.g., TiN, TiAlN) generally do not change the classification, but the substrate material does. Misclassifying a carbide tool as a steel tool — or vice versa — can result in incorrect duty rates and potential antidumping liability.
