7102.29.00.10 - Carbonados

This classification, HTS 7102.29.00.10, specifically covers "Carbonados," which are a type of industrial diamond. Carbonados are polycrystalline diamonds characterized by their black or dark color, extreme toughness, and opacity. Unlike single-crystal diamonds, they are composed of numerous small diamond crystals fused together. Their primary utility lies in industrial applications requiring exceptional hardness and durability, such as in drilling bits, cutting tools, and abrasives.

Within the broader category of "Miners' diamonds" (7102.29.00), carbonados are distinguished from other types of industrial diamonds by their unique polycrystalline structure and appearance. While other industrial diamonds at this level might include bort or ballas, carbonados are specifically identified by their carbonado properties. The sibling category, HTS 7102.29.00.20, "Other," would encompass any industrial diamonds that do not fall under the specific definition of carbonados.

As this is a leaf node within the HTS structure, there are no further subcategories under 7102.29.00.10. Classification at this level is definitive for goods meeting the specific criteria of carbonados, ensuring precise import and export declaration based on their material composition and intended industrial use.
