8202.39.00.10 - With diamond working parts

This HTS classification covers circular saw blades, including slitting or slotting saw blades, that are specifically designed with diamond working parts. This designation applies to blades where the cutting elements or abrasive surfaces are composed of diamond, which is typically used for cutting hard, brittle materials such as stone, concrete, tile, and glass. The presence of diamond working parts is the defining characteristic for classification under this subheading, distinguishing it from other types of circular saw blades.

Circular saw blades classified under 8202.39.00.10 are differentiated from their sibling categories by the explicit inclusion of diamond in their construction. For instance, "Diamond sawblade cores" (8202.39.00.40) would refer to the base metal disk or body of the blade, typically without the diamond cutting edge attached or specified. "Other" (8202.39.00.70) would encompass circular saw blades that do not have diamond working parts, such as those with teeth made of high-speed steel or carbide.

As this is a leaf node, there are no further subcategories. Therefore, classification under 8202.39.00.10 hinges entirely on the presence of diamond working parts on the circular saw blade. Importers should ensure that the product's physical characteristics and intended use align with the diamond cutting capability to correctly apply this tariff code.
