7103.91.00.20 - Sapphires

This HTS classification, 7103.91.00.20, specifically covers sapphires, which are a type of precious stone. These sapphires, whether they have been cut, polished, or otherwise worked, are classified here provided they are not yet strung, mounted, or set into jewelry or other articles. This designation also includes ungraded sapphires that are temporarily strung solely for ease of transport. The key characteristic is the material – sapphire – and its state of processing before incorporation into a finished product.

Sapphires are distinguished from their siblings within this classification by their distinct chemical composition and resulting color. While rubies (7103.91.00.10) are also corundum but red in color, and emeralds (7103.91.00.30) are beryl and green, sapphires are primarily known for their blue hue, though they can occur in a variety of other colors (except red). This specific sub-classification ensures accurate trade data by isolating sapphires from other precious stones of similar working states.

As this HTS code represents a leaf node, there are no further subcategories branching from it. Therefore, the focus remains on the accurate identification and classification of loose or temporarily strung sapphires, ensuring they are not mistakenly classified under related headings for worked precious stones that have been incorporated into finished articles.
