Last updated: April 2026 dataCermet-tipped rock drilling and earth boring tools occupy a specialized niche in mining, construction, and geotechnical drilling, where the tungsten carbide–metal matrix composition of the working part delivers superior wear resistance over plain steel. Imports enter under a single 10-digit line (8207130000), simplifying classification but not necessarily duty exposure — Chinese-origin goods in this category are subject to Section 301 tariffs. Mexico leads US supply, followed by China and Sweden, reflecting both proximity-driven manufacturing and Scandinavian dominance in premium hard-rock tooling.

Under HTS heading 8207, the working-part material is the primary classification driver. Cermet working parts (sintered metal-ceramic composites, typically tungsten carbide in a metallic binder) fall under 820713, while tools with diamond working parts or other materials classify elsewhere. If a tool has a cermet insert but a different primary cutting element, the classification may shift — consult a licensed customs broker to confirm.
Yes. Rock drilling and earth boring tools with cermet working parts imported from China are generally subject to Section 301 additional tariffs. Importers sourcing from Mexico or Sweden are not subject to Section 301, though standard MFN duties still apply.
