7418.20.10.00 - Of copper-zinc base alloys (brass)

This HTS subheading, 7418.20.10.00, specifically classifies sanitary ware and parts thereof that are made from copper-zinc base alloys, commonly known as brass. This includes items such as faucets, spigots, sinks, bathtubs, and related plumbing fixtures designed for use in bathrooms, kitchens, and other sanitary areas, when constructed from brass. The classification hinges on both the function (sanitary ware) and the primary material composition (brass).

In contrast to its sibling category, 7418.20.50.00 ("Other"), which would encompass sanitary ware and parts made from other forms of copper or copper alloys not specifically enumerated, this subheading is precise in its material requirement. Any sanitary ware made from pure copper or other copper alloys (like tin bronze or aluminum bronze) would fall under the "Other" category, not this specific brass-based classification.

As this subheading represents a leaf node within the HTS structure, there are no further subcategories. Therefore, classification at this level is final, with the defining criteria being the item's designation as sanitary ware or a part thereof, and its explicit construction from copper-zinc base alloys (brass). The intent and design for sanitation purposes are paramount in distinguishing these articles from general articles of copper.
