7105.10.00 - Of diamonds

This HTS category, 7105.10.00, specifically addresses dust and powder derived from natural diamonds. It encompasses finely ground or pulverized natural diamond material, regardless of its intended application, whether for industrial abrasives, polishing compounds, or other specialized uses. The key distinguishing factor for this classification is the origin of the diamond material, which must be natural.

This category is differentiated from its sibling, 7105.90.00.00 ("Other"), by its exclusive focus on diamond-based materials. While 7105.90.00.00 would cover dust and powder from other precious or semi-precious stones (such as synthetic diamonds, rubies, sapphires, or emeralds), this specific sub-heading is solely for the diamond variety. The "II. PRECIOUS METALS AND METALS CLAD WITH PRECIOUS METAL" sibling category pertains to an entirely different class of goods and is not relevant to dust and powder classifications.

Further subdivision within this category distinguishes between natural and synthetic sources. While 7105.10.00 itself pertains to natural diamonds, the broader structure allows for separate consideration of synthetic diamond dust and powder, recognizing potential differences in composition, production, and application that might necessitate distinct tariff treatments.
