3824.99.19.00 - Other

This HTS category, 3824.99.19.00, encompasses "Other" cultured crystals, specifically those not meeting the criteria of the sibling category. It is important to note that these cultured crystals must weigh not less than 2.5 grams each to be classified here. This classification applies to synthetic crystalline materials produced for various industrial applications, excluding those that are specifically designed as optical elements and fall under Chapter 90 of the HTS.

The defining characteristic for this specific subcategory, 3824.99.19.00, is the absence of a particular form or characteristic that would place it in other related subheadings. Unlike sibling categories that might specify a form (e.g., "in the form of ingots"), this classification covers cultured crystals that are not presented in such pre-defined shapes and are therefore considered "other" within the broader category of cultured crystals.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. Classification within 3824.99.19.00 is final for cultured crystals meeting the weight requirement and not fitting into more specific descriptions or forms. The focus for classification here is therefore on the inherent nature of the cultured crystal itself and its weight, ensuring it is not an optical element from Chapter 90 and does not conform to any alternative specific forms mentioned elsewhere.
