7801.91.00.00 - Containing by weight antimony as the principal other element

This HTS classification, 7801.91.00.00, specifically covers unwrought lead that contains antimony as its principal other alloying element by weight. This means that while lead is the base metal, antimony is present in a greater proportion than any other alloying element. Such materials are typically in their raw, unworked forms, such as ingots, pigs, or cast shapes, and are intended for further processing. Examples include lead alloys specifically formulated with antimony for use in battery grids, ammunition, or radiation shielding.

It is crucial to distinguish this category from its sibling, 7801.99, which covers other unwrought lead not falling under the antimony-alloyed classification. The defining characteristic here is the quantifiable presence and dominance of antimony as the primary alloying agent. If the unwrought lead contains other alloying elements in greater proportion than antimony, or if it is essentially pure lead with only trace amounts of other elements, it would be classified elsewhere.

As this HTS code represents a leaf node, there are no further subcategories. Therefore, classification within 7801.91.00.00 relies solely on verifying that the unwrought lead's composition meets the criterion of antimony being the principal other element by weight, as determined by chemical analysis or product specifications.
