Product classification
HS code for Copper screws: 7415.33
Copper, screws, bolts and nuts, threaded.
Classification of copper screws under HS 7415.33
Copper screws are classified under HS code 7415.33. This classification is determined by Heading 7415, which covers both threaded and non-threaded copper fasteners. Subheading 7415.33 is specifically reserved for threaded screws, bolts, and nuts. The presence of a helical thread is the defining characteristic that separates these items from the non-threaded articles in the same heading. The Harmonized System groups these products based on their mechanical function and material composition. To be classified here, the screw must be made of copper or a copper alloy, such as brass or bronze. The classification remains the same regardless of the screw's head type (e.g., slotted, Phillips, hex) or its specific application (e.g., wood screws, machine screws). This code is essential for hardware distributors and manufacturers in the electrical and marine sectors where copper-based threaded fasteners are preferred for their conductivity and resistance to salt-water corrosion.

Codes often confused with 7415.33
Common mistake. The most frequent misclassification occurs with HS code 7415.21, which is for copper washers. While washers are often used with screws, they are non-threaded and have their own specific subheading. Additionally, steel screws that are merely copper-plated must be classified under Heading 7318, as the underlying base metal (iron or steel) dictates the classification rather than the surface coating.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
