9817.82.01 - Mounted tool and drill bit blanks of polycrystalline diamond (provided for in subheadings 8207.19.60, 8207.50.40 or 8207.50.80) and mounted tool blanks of polycrystalline diamond (provided for in subheadings 8207.70.60, 8207.80.60, 8207.90.45 or 8207.90.75

HTS Code 9817.82.01 specifically designates mounted tool and drill bit blanks crafted from polycrystalline diamond. This classification also encompasses mounted tool blanks made from the same advanced material. The key defining feature for inclusion here is the specific material composition (polycrystalline diamond) and the fact that these are blanks, meaning they are intended for further processing into finished tools. The parenthetical references within the description are crucial, pointing to specific subheadings in Chapter 82, which covers tools, implements, cutlery, spoons and forks, of base metal; parts thereof of base metal.

This special classification provision exists to address specific types of diamond tool blanks that might otherwise fall under more general tool or material classifications. While siblings within Chapter 98 might cover other "special classification provisions" or temporary modifications, 9817.82.01 is narrowly focused on these high-performance diamond-based cutting tool precursors. It is important to differentiate these blanks from finished tools of polycrystalline diamond, which would be classified under the referenced subheadings in Chapter 82, or from other types of cutting tools not made of polycrystalline diamond.

As a leaf node, HTS 9817.82.01 does not have further subcategories. The classification is definitive for mounted tool and drill bit blanks made of polycrystalline diamond, with the precise nature of the blank and its intended use (tool or drill bit) being the primary factors. Importers must ensure that the goods precisely match the material and form described and can identify the corresponding Chapter 82 subheading to which the blank is intended to be incorporated.
