7102.21.40.00 - Other

This HTS classification, 7102.21.40.00, pertains to "Other" industrial diamonds that are unworked or have undergone only basic processing such as sawing, cleaving, or bruting. These diamonds are intended for industrial applications rather than for use as gemstones. The defining characteristic of this category is the absence of any further working beyond these initial stages, distinguishing them from diamonds that have been cut, polished, or otherwise significantly shaped.

This category is differentiated from its sibling, 7102.21.30.00, by the scope of processing. While 7102.21.30.00 specifically enumerates diamonds that have been simply sawn, cleaved, or bruted, this "Other" category encompasses industrial diamonds that fall under the broader "unworked or simply sawn, cleaved or bruted" heading but do not fit neatly into the more specifically defined sibling. This often includes diamonds that may have undergone initial rough shaping or sorting but are still fundamentally in a raw or semi-processed state for industrial use.

As this is a leaf node within the HTS structure, there are no further subcategories. The classification is complete at this level, meaning that any unworked or minimally processed industrial diamond not specifically covered by the sibling category will be classified here. The focus for customs purposes will be on confirming the industrial nature of the diamond and the limited extent of its physical manipulation.
