HS code for Copper washers: 7415.21
Copper, washers, (including spring washers), not threaded.
Classification of copper washers under HS 7415.21
Copper washers are classified under HS code 741521. This code is situated within Heading 7415, which covers a broad range of copper fasteners and similar articles, including nails, tacks, drawing pins, staples, bolts, and nuts. Specifically, the sub-heading 741521 is dedicated to non-threaded washers, including spring washers and other types of locking washers. The classification is determined by the material composition (copper or copper alloys) and the mechanical nature of the item (non-threaded). Washers are used to distribute the load of a threaded fastener or to provide a seal or spacing. Because copper is non-magnetic and resistant to corrosion, these washers are frequently used in electrical and marine applications. The HS system groups these by material rather than function, so even if a washer is used in an engine, its material composition as copper dictates its placement in Chapter 74.

Codes often confused with 7415.21
Common mistake. Copper washers are often confused with steel or iron washers, which are classified under HS code 731822. They may also be misclassified under 741533 if they are part of a threaded assembly, though 741521 is strictly for the non-threaded washer component. If the washer is made of a copper-zinc alloy (brass), it still remains in 7415 but must be checked against specific alloy subheadings if applicable in local tariffs.

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).
