7415.33.80 - Other screws and bolts; nuts

This category, HTS 7415.33.80, encompasses "Other screws and bolts; nuts" made of copper or copper alloys, that are not specifically classified under preceding subheadings. Unlike sibling categories such as screws for wood (7415.33.05.00) or Muntz or yellow metal bolts (7415.33.10.00), this heading captures a broader range of copper threaded fasteners and nuts intended for general industrial or mechanical applications, excluding those with specialized uses or compositions outlined elsewhere. The key differentiator lies in the exclusion of items with specific named purposes or material compositions already detailed.

The classification within this category is further refined by the diameter of the shank, threads, or bore hole. Subcategories distinguish between fasteners and nuts with a diameter measuring 6 mm or more (7415.33.80.10) and those with a diameter less than 6 mm (7415.33.80.50). This physical dimension is a critical criterion for accurate classification, ensuring that the correct tariff and duty rates are applied based on the scale and intended application of the copper threaded articles.
