7115.90.30.00 - Of gold, including metal clad with gold

This HTS category, 7115.90.30.00, encompasses articles that are predominantly composed of gold or are made of base metals clad with gold. This includes a wide array of manufactured goods where gold is the primary precious metal by weight or value, or where a non-precious metal core is covered by a layer of gold. Such items can range from decorative objects and components for machinery to specialized scientific equipment or even certain types of jewelry, provided they meet the criteria of being "of gold" or "metal clad with gold" and are not specifically classified elsewhere.

Crucially, this classification differentiates itself from its siblings by its material composition. Articles classified under 7115.90.40.00 are specifically "Of silver, including metal clad with silver," indicating a different precious metal as the primary component. The sibling category 7115.90.60.00, "Other," would cover articles of precious metal or metal clad with precious metal that do not fit into the gold or silver specific categories and are not otherwise classified. Therefore, the defining characteristic for 7115.90.30.00 is the presence of gold as the principal precious metal element.

As this is a leaf node in the HTS classification system, there are no further subcategories to introduce. Classification under this code is final based on the material of the article. When classifying, particular attention should be paid to the proportion of gold in the item, whether by weight or value, and the nature of any base metal used in cladding, ensuring it meets the established criteria for this specific "of gold" designation.
