HS Code for Steel washers

Non-threaded steel washers are classified under HS code 7318.22. This classification is part of the broader heading 7318, which covers a wide range of fasteners and hardware made of iron or steel. Subheading 7318.22 is specifically reserved for plain or flat washers that do not possess a locking or spring mechanism. The classification is determined by the physical form—typically a thin plate with a central hole—and the lack of threads. These components are essential in mechanical assemblies to distribute the load of a threaded fastener, such as a bolt or nut, and to prevent damage to the surface being fastened. The material must be iron or steel; washers made of other metals like copper or aluminum, or those made of plastics, would be classified in their respective material chapters. The 7318 heading distinguishes between threaded articles (like screws and bolts) and non-threaded articles (like rivets, cotters, and washers).

Common Misclassification

Steel washers are most commonly misclassified under HS code 7318.21, which is specifically for spring washers and other lock washers. It is vital to distinguish between a plain flat washer and one designed with a tension or locking feature. They are also sometimes confused with 7318.15 if they are imported as part of a bolt and nut assembly, though they should generally be classified separately unless they form a single inseparable unit. Washers made of stainless steel are still under 7318.22, but washers of other base metals move to headings like 7415 (copper).
