7103.91.00.30 - Emeralds

This HTS classification, 7103.91.00.30, specifically designates emeralds. Emeralds are precious stones characterized by their distinctive green color, which is due to the presence of chromium and sometimes vanadium. This category encompasses emeralds that have undergone any form of working or grading, such as cutting, polishing, or sorting by size and quality, provided they are not yet strung, mounted, or set. Ungraded emeralds temporarily strung for ease of transport also fall under this heading.

This category is distinguished from its siblings by the specific gemstone. While 7103.91.00.10 covers rubies and 7103.91.00.20 covers sapphires, this classification is exclusively for emeralds, focusing on their unique mineral composition and appearance. All three sibling categories, however, fall under the broader heading of "Rubies, sapphires and emeralds" within the "Otherwise worked" section of precious and semiprecious stones.

As this is a leaf node in the HTS database, there are no further subcategories that subdivide the classification of emeralds. Therefore, the focus remains on the accurate identification and working state of the emeralds to ensure correct classification. Classification decisions at this level will primarily rely on the physical characteristics and the absence of any mounting or setting.
