7907.00.20.00 - Zinc tubes, pipes and tube or pipe fittings (for example, couplings, elbows, sleeves)

This HTS category, 7907.00.20.00, specifically covers articles manufactured from zinc in the form of tubes, pipes, and fittings. This includes items like couplings, elbows, sleeves, and other connectors or components designed to be used with zinc tubing or piping. The key defining characteristic for classification here is the form and function of the article as a conduit or a connecting piece, made predominantly of zinc.

This classification is distinct from its sibling category, 7907.00.10.00, which pertains to zinc articles used for household, table, kitchen, or sanitary purposes. While both fall under "Other articles of zinc," the focus of 7907.00.20.00 is on functional pipeline components, not on finished goods for domestic or personal hygiene use. It is also separate from 7907.00.60.00, which serves as a residual category for all other zinc articles not specified elsewhere.

As this is a leaf node in the HTS structure, there are no further subcategories. Classification under this heading is determined by the material (zinc) and the specific form (tubes, pipes, and fittings) and intended use of the article. Practical classification will rely on the physical characteristics and stated purpose of the imported or exported goods, ensuring they align precisely with the definition of zinc conduits and their associated fittings.
