Last updated: July 2026 dataCopper washers — including spring (lock) washers — are widely used in plumbing, hydraulic fittings, and precision instrumentation where their malleability creates a reliable metal-to-metal seal and their conductivity aids grounding. All imports enter under the single tariff line 7415210000, which covers non-threaded washers only; threaded copper fasteners fall under separate subheadings. South Korea leads US supply, followed by India and Taiwan, reflecting strong precision-parts manufacturing capacity in those markets. Classifiers should confirm that the washer is non-threaded, as threaded copper articles are excluded from this subheading.

Heading 7415.21 covers non-threaded washers of copper, including spring (lock) washers. If a washer is threaded or is integral to a threaded fastener assembly, it would be classified under the threaded fastener subheadings of 7415. Additionally, washers that are part of a complete valve or fitting assembly may be classified with the parent article rather than separately.
Copper washers are a standard sealing component in plumbing and HVAC fittings, hydraulic and pneumatic systems, automotive fuel and brake lines, and electrical grounding assemblies. Their softness allows them to deform under torque and create leak-proof seals, making them preferred over harder metals in high-pressure fluid applications.
