Last updated: August 2026 dataThreaded fasteners of iron or steel — including screws, bolts, nuts, screw hooks, rivets, and washers — are a foundational input for automotive, construction, and industrial machinery assembly, and have been a recurring focus of antidumping and countervailing duty proceedings targeting imports from several major producing countries. The threading requirement is the key classification boundary: articles in this heading carry a helical thread, distinguishing them from the non-threaded variants in heading 69422. Importers should confirm whether specific product lines are covered by any active trade remedy orders before entry.

Heading 69421 covers fasteners with a helical thread — screws, bolts, nuts, and threaded washers. Non-threaded articles such as plain washers, rivets without threads, and similar items fall under heading 69422. The presence or absence of a functional thread is the determining factor, and borderline articles may require a binding ruling from CBP.
Yes. Certain categories of threaded steel fasteners, including steel nuts and screws, have been subject to antidumping and countervailing duty orders from the US Department of Commerce targeting imports from specific countries. Importers must check the USITC and Commerce databases for active orders covering their specific product and country of origin before importation.
