Overview

This HTS classification, specifically 7102.21.10.10, covers "Carbonados." Carbonados are a specific type of industrial diamond characterized by their opaque, black or dark coloration, dense microcrystalline structure, and exceptional toughness. Unlike gem-quality diamonds, carbonados are primarily valued for their industrial applications due to their hardness and resilience, making them ideal for cutting, grinding, and drilling tools.

This category is distinguished from its sibling, 7102.21.10.20 "Other," which would encompass other types of industrial diamonds that are unworked or simply sawn, cleaved, or bruted but do not meet the specific definition of carbonados. The key differentiator lies in the specific physical properties and appearance of carbonados, particularly their opacity and granular structure, which set them apart from other industrial diamond forms at this level.

As this is a leaf node within the HTS structure, there are no further subcategories. Therefore, classification under 7102.21.10.10 is definitive for identified carbonados that are unworked or simply sawn, cleaved, or bruted. Importers and exporters should ensure that the diamonds presented for classification possess the defining characteristics of carbonados, such as their dark, opaque appearance and microcrystalline structure, to correctly utilize this specific HTS code.
