7317.00.55.30 - Galvanized

This HTS category, 7317.00.55.30, specifically covers galvanized nails, tacks, drawing pins, corrugated nails, staples, and similar articles of iron or steel that are made of round wire, are of one-piece construction, and possess a smooth shank. The key defining characteristic for inclusion here is the surface treatment: these articles are coated with zinc through a galvanization process, which provides corrosion resistance. This distinguishes them from other similarly constructed fasteners.

The "Galvanized" subcategory differentiates itself from its sibling, 7317.00.55.40, which is reserved for fasteners coated with vinyl, resin, or cement. This node is also distinct from 7317.00.55.50, the "Other" category at this level, which would encompass fasteners with different, non-galvanized coatings or no coating at all. As this is a leaf node, there are no further subdivisions. Therefore, the classification hinges entirely on the material (iron or steel), construction (one-piece, round wire, smooth shank), and the specific galvanization process.
