8302.49.80.40 - Of copper

This classification, HTS Code 8302.49.80.40, specifically addresses base metal mountings, fittings, and similar articles intended for use in the construction or equipping of railway vehicles, aircraft, vessels, and other vehicles within Section XVII, excluding motor vehicles. The defining characteristic here is the material composition, which must be of copper. This includes a broad range of components such as hinges, latches, brackets, handles, and other securing or functional hardware where copper is the primary base metal.

The distinction from its sibling category, 8302.49.80.50, lies solely in the material. While both cover similar types of fittings for vehicles, this specific code mandates that the articles be *of copper*. The sibling category, labeled "Other," would encompass fittings made from base metals other than copper, or those where copper is not the predominant metal. This focus on copper is crucial for accurately applying duty rates and trade regulations.

As this is a leaf node within the HTS, there are no further subcategories. Classification at this level is final, emphasizing the precise identification of copper-based fittings for non-motorized vehicles. Examples would include copper hinges for aircraft cargo doors, copper latches for railway carriage compartments, or copper brackets for marine equipment. The ultimate determination rests on the item's physical form, its intended application within the specified vehicle types, and the confirmed presence of copper as the primary base metal.
