Overview
HTS code 7318.22.00.00 encompasses various types of washers made of iron or steel that are not specifically spring washers or lock washers. These are typically flat or ring-shaped articles with a central hole, designed to distribute the load of a bolted or screwed fastening, to prevent damage to the material being fastened, or to provide a seal. They serve a crucial function in mechanical assemblies by ensuring secure and stable connections.
This category is distinguished from its sibling, 7318.21.00, which specifically covers spring washers and other lock washers. While both are types of washers, 7318.21.00 is reserved for those with designs intended to prevent loosening due to vibration or thermal expansion, such as split washers or toothed washers. The "Other washers" classification, 7318.22.00.00, therefore applies to standard flat washers and similar non-locking washer types.
As a leaf node in the HTS classification structure, 7318.22.00.00 does not have further subdivisions. Classification into this code relies on the physical characteristics of the article, confirming it is a washer made of iron or steel, and ensuring it does not meet the specific criteria for spring or lock washers found in the preceding sibling category. Common examples include standard flat washers, sealing washers (without integral sealing elements), and certain types of grommets that function similarly to washers.
