7102.39.00.50 - Weighing over 0.5 carat each

This HTS classification covers non-industrial diamonds that have been worked but are not mounted or set, and specifically those weighing over 0.5 carat each. This means the diamonds have undergone processing such as cutting, polishing, or faceting, rendering them suitable for use in jewelry or other ornamental applications, but are still loose.

The key differentiator for this category, 7102.39.00.50, is the weight criterion. It is distinguished from its sibling category, 7102.39.00.10, by the requirement that each individual diamond must weigh more than 0.5 carat. Diamonds weighing 0.5 carat or less fall under the alternative sibling classification.

As this is a leaf node in the Harmonized Tariff Schedule, there are no further subcategories. Therefore, classification under 7102.39.00.50 is solely determined by the diamond being worked, unmounted, un-set, and exceeding the 0.5 carat weight threshold per stone.
