Last updated: August 2026 dataPlain and flat washers of iron or steel — used to distribute fastener load, reduce surface damage, and provide sealing in bolted joints — are classified under a single 10-digit line (7318220000), making origin and material the primary variables affecting duty liability. China is the dominant supplier, with Taiwan, Japan, India, and Germany also contributing to US import volumes. Because plain washers are a commodity fastener with thin margins, Section 301 tariff exposure on Chinese-origin goods has made Taiwan and India increasingly competitive alternative sources for high-volume buyers.

Composite washers combining a metal ring with a non-metallic sealing element may be classified differently depending on the essential character determination — they could fall under a gasket or sealing heading rather than 731822. If the metal component is clearly the primary functional element and the non-metallic insert is incidental, classification as a washer may still apply, but importers should seek a binding ruling from CBP for composite designs to avoid misclassification.
The functional distinction is determinative: lock washers (731821) are designed to resist loosening through spring tension or tooth engagement, while plain washers (731822) serve only to distribute load or protect surfaces. A flat washer with no locking feature — regardless of thickness or hardness — belongs in 731822. Importers mixing both types in a single shipment should ensure each SKU is correctly segregated on the commercial invoice.
