8207.19.60.65 - With working part of diamonds

This HTS category, 8207.19.60.65, specifically covers interchangeable tools designed for drilling into rock or earth, and any parts thereof, when their working part is made of diamonds. These tools are designed for heavy-duty applications in mining, construction, and geological exploration, utilizing the exceptional hardness of diamond to penetrate durable materials. Examples include diamond core bits for sample extraction, diamond drill bits for creating boreholes, and diamond reamers for enlarging existing holes.

This classification is distinguished from its sibling category, 8207.19.60.70 (Other), by the explicit requirement of a working part composed of diamonds. The sibling category would encompass rock drilling or earth boring tools and parts that do not feature a diamond working part, such as those made with carbide or other hard alloys. The focus here is solely on the diamond composition of the cutting or abrasive surface, which dictates its specific application and often its higher cost and performance characteristics.

As this node represents a leaf node in the HTS, there are no further subcategories. Classification at this level is determined by the diamond composition of the working part of rock drilling or earth boring tools and their associated parts. Importers and exporters should ensure that the documentation accurately reflects the diamond content of the working part to ensure correct customs declaration and duty assessment.
