7317.00.55.01 - Collated roofing nails with a length of 20.6 mm to 46.1 mm, a head diameter of 8.3 mm to 10.6 mm, a shank diameter of 2.5 mm to 3.2 mm, whether or not galvanized

This HTS classification covers specific types of collated roofing nails made from iron or steel. These nails are characterized by their precise dimensions, including a length range of 20.6 mm to 46.1 mm, a head diameter between 8.3 mm and 10.6 mm, and a shank diameter of 2.5 mm to 3.2 mm. The classification explicitly includes nails that are galvanized, indicating the presence or absence of zinc coating does not alter their classification within this category.

This specific subcategory differentiates itself from other "collated nails" by the detailed dimensional and functional specifications. While other collated nails might exist, this entry is reserved for those meeting the prescribed length, head diameter, and shank diameter ranges, designed for roofing applications. The parent category of "Made of round wire" establishes that the nails are formed from a single piece of round metal wire, and the "Collated" aspect signifies they are joined together in strips or coils for use in nail guns.

As this is a leaf node in the HTS structure, there are no further subdivisions. Therefore, the focus for classification under 7317.00.55.01 is on verifying that the collated roofing nails precisely match the specified physical parameters and material composition. Misclassification would occur if the nails fall outside these precise dimensional tolerances or are made from materials other than iron or steel.
