8207.70.30.40 - Router bits for woodworking

This HTS category, 8207.70.30.40, specifically classifies router bits designed for woodworking applications. These tools are intended for use with hand-held routers or larger milling machines to shape, cut, or create decorative profiles in wood. The defining characteristic for this classification is the material composition of the cutting part, which must contain by weight over 0.2 percent of chromium, molybdenum, or tungsten, or over 0.1 percent of vanadium. This composition typically indicates the use of high-speed steel or carbide alloys, providing durability and cutting efficiency for woodworking.

While this category and its siblings all fall under interchangeable tools for milling, 8207.70.30.40 is distinct in its primary application. Its sibling, 8207.70.30.30, specifically covers end milling cutters, which are a type of milling tool but may have different applications or specific geometries. The "Other" category, 8207.70.30.60, serves as a catch-all for milling tools that do not fit the specific criteria of router bits or end milling cutters. Therefore, the key differentiator here is the intended use in routing operations within the woodworking sector, coupled with the specified alloy content.

As a leaf node, this category does not have further subdivisions. Classification within 8207.70.30.40 hinges on confirming that the tool is a router bit for woodworking and that its cutting element meets the stated metallurgical requirements. This ensures accurate tariff application for these specialized woodworking tools.
