8207.70.60.40 - Router bits not suitable for cutting metal

This HTS category, 8207.70.60.40, specifically encompasses router bits that are not designed or intended for cutting metal. These bits are exclusively for use with routing machinery and are typically employed for shaping, grooving, or cutting softer materials such as wood, plastics, composites, and other non-metallic substances. The key defining characteristic for classification under this heading is the material suitability; if a bit is only effective on non-metal materials, it falls here.

This subcategory is distinct from its sibling, 8207.70.60.30, which covers "End milling cutters." While both are types of milling tools, end milling cutters are generally designed for more aggressive material removal and can often be used on metal, whereas the items under 8207.70.60.40 are manufactured with geometries and cutting edges optimized for non-metals. It also differs from the sibling category 8207.70.60.60, "Other (including parts)," which serves as a residual category for other milling tools and their component parts not specifically enumerated elsewhere.

As this is a leaf node within the HTS, there are no further subcategories to introduce. Classification under this specific code relies on the precise application and material limitations of the router bit. Therefore, when determining classification, it is crucial to confirm that the bit's intended use and capabilities are strictly limited to non-metallic materials.
