HS Code 7415.21 – Copper; washers, (including spring washers), not threaded

HS code 7415.21 is the 6-digit subheading for copper, washers, (including spring washers), not threaded. It is used for copper flat washers, copper spring washers, copper lock washers, copper sealing washers and copper crush washers.

What HS 7415.21 covers

This HS code covers unthreaded washers, including spring washers, made from copper. These components are fundamental in mechanical assemblies across a multitude of industries, providing load distribution, vibration dampening, and preventing loosening of fasteners. Copper washers are particularly prized for their excellent electrical conductivity, thermal conductivity, and corrosion resistance, making them indispensable in electrical systems, plumbing, automotive, and marine applications where these properties are critical. Major importers are typically industrialized nations with significant manufacturing bases, such as Germany, the United States, Japan, and Mexico, which integrate these washers into their finished products. Leading exporters include countries with advanced metal fabrication industries and access to copper resources, like China, Germany, and Taiwan. Traders should pay close attention to the specific dimensions, material grade (e.g., pure copper vs. brass), and whether they are plain or spring washers, as these details significantly impact their application and market value.

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).
