7105.10.00.30 - 80 mesh or finer

This HTS category, 7105.10.00.30, specifically classifies dust and powder derived from synthetic diamonds that are processed to a fineness of 80 mesh or finer. This classification is applicable when the particulate form of synthetic diamond is intended for industrial applications where its abrasive or polishing properties are paramount. The "80 mesh or finer" criterion is a critical physical characteristic, indicating a very high degree of refinement and small particle size, essential for precision grinding, lapping, and polishing operations.

Distinguishing this category from its sibling, 7105.10.00.50, which covers "Other" dust and powder of synthetic diamonds, lies in the specified particle size. While the sibling category encompasses all other dusts and powders of synthetic diamonds regardless of mesh size, 7105.10.00.30 is exclusively for those meeting the stringent 80 mesh or finer standard. This distinction is crucial for tariffs and trade statistics, as the finer grades often command different market values and have specialized uses.

As this is a leaf node in the HTS classification structure, there are no further subcategories. Therefore, understanding the scope of this classification relies heavily on the precise definition of "80 mesh or finer" and the material being synthetic diamond. Importers and exporters must ensure their product's specifications accurately reflect this particle size to ensure correct declaration and compliance with customs regulations.
