6804.21.00.20 - Articles consisting of a continuous rim segment of diamond agglomerated with metal, attached to circular plates of steel (whether or not attached to non-steel plates)

This HTS classification covers specific cutting tools designed for industrial applications, primarily circular sawblades. The defining characteristic of these articles is the continuous rim segment, which is composed of diamond particles firmly bound together with metal. This agglomerated diamond rim is then securely attached to a circular plate made of steel. The classification also includes instances where non-steel plates are also incorporated into the assembly, as long as the primary cutting edge is formed by the continuous rim segment affixed to the steel plate.

It is crucial to distinguish this category from its siblings. HTS 6804.21.00.10 pertains to individual segments intended for attachment to sawblades, rather than the complete, assembled circular sawblade. Furthermore, HTS 6804.21.00.30 covers circular plates fitted with multiple diamond segments but lacking the continuous rim characteristic of the article classified under 6804.21.00.20; these are generally used for applications other than the continuous cutting action of a sawblade. HTS 6804.21.00.90 serves as a residual category for any other items of agglomerated synthetic or natural diamond within the broader scope of Chapter 68 that do not meet the specific criteria of the preceding subheadings.

As this classification represents a leaf node within the HTS structure, there are no further subdivisions under this specific code. The focus remains on the precise physical configuration: a continuous rim of diamond agglomerated with metal, attached to circular steel plates, defining its unique application and composition within the broader family of grinding and cutting wheels.
