8202.39.00.40 - Diamond sawblade cores

This classification, HTS Code 8202.39.00.40, specifically covers diamond sawblade cores. These are the foundational circular disks of metal, designed to be fitted with diamond cutting segments, but which do not yet possess those diamond working parts. Their primary purpose is to serve as the substrate for diamond-tipped blades used in cutting hard materials such as concrete, stone, and ceramics.

It is important to distinguish this category from its sibling, 8202.39.00.10, which covers circular saw blades that *do* have diamond working parts. The core itself, before the diamond segments are attached, falls under 8202.39.00.40. The "Other" sibling category, 8202.39.00.70, would encompass circular saw blades that do not have diamond working parts and are not otherwise specifically classified.

As this classification is a leaf node, there are no further subcategories. The classification of a diamond sawblade core hinges on its structural integrity and readiness for the subsequent addition of diamond segments, distinguishing it from completed diamond saw blades or other types of circular saw blades.
