7104.99.50.00 - Other

This HTS category, 7104.99.50.00, encompasses synthetic or reconstructed precious or semiprecious stones that are not specifically covered by other subheadings within heading 7104. These materials, whether worked or graded but not yet strung, mounted, or set, fall into this classification if they do not meet the criteria for more specific designations. This includes stones that may have undergone preliminary processing, such as cutting or faceting, but are not yet prepared for direct incorporation into jewelry or other finished articles.

It is crucial to distinguish this "Other" category from its sibling, 7104.99.10.00. While both deal with worked synthetic or reconstructed stones, 7104.99.10.00 specifically covers stones that are cut but not set, and are demonstrably suitable for use in the manufacture of jewelry. Category 7104.99.50.00, conversely, is for those synthetic or reconstructed stones that are otherwise processed or graded but do not fit the specific jewelry-manufacturing suitability criteria of the sibling. This might include stones prepared for industrial applications, for collection, or those that have undergone grading without being designated as ready for jewelry production.

As this is a leaf node within the HTS, there are no further subcategories. Therefore, classification within 7104.99.50.00 relies on a careful assessment of the material's characteristics and processing stage, ensuring it is not captured by more specific provisions for natural stones, worked precious metals, or finished articles. The defining factor is that these are synthetic or reconstructed stones that have been worked or graded but do not meet the specific requirements for other enumerations within this heading.
