7317.00.55.70 - Galvanized

This HTS category, 7317.00.55.70, specifically covers fasteners such as nails, tacks, and staples made of iron or steel that are galvanized. This includes articles of one-piece construction, manufactured from round wire, and are further classified under the broader headings for "Other" nails and fasteners. The galvanization process, which applies a protective zinc coating, is the defining characteristic of goods falling within this specific sub-heading.

This classification distinguishes itself from its sibling category, 7317.00.55.80, which covers fasteners coated with vinyl, resin, or cement. While both are coated, the material of the coating is the key differentiator. Furthermore, 7317.00.55.90 encompasses all other coated fasteners not specifically described by galvanization, vinyl, resin, or cement.

As this is a leaf node, there are no further subcategories. Therefore, the classification hinges directly on the material of the fastener being iron or steel, its construction from round wire, and importantly, its galvanization. Examples within this category would include standard galvanized nails used in construction or galvanized staples used in industrial applications, provided they meet all the preceding criteria.
