Last updated: August 2026 dataThreaded copper fasteners not elsewhere specified — such as set screws, eye bolts, or specialty threaded inserts of copper — fall under the residual line 7415390000 when they do not fit the more specific descriptions of screws, bolts, or nuts in 7415.33. Taiwan is the leading US supplier, followed by Mexico and China. Because this is a catch-all subheading within the threaded fastener group, classification here requires confirming that the article is threaded, is of copper (or iron/steel with copper heads), and does not match any of the more specific 7415.33 descriptions — a step-by-step exclusion analysis is advisable.

Articles such as threaded copper inserts, eye bolts, hook bolts, U-bolts, and specialty threaded connectors that do not fit the specific descriptions of wood screws, Muntz bolts, or standard screws/nuts/bolts in 7415.33 are candidates for 7415.39. The key is that the article must be threaded; non-threaded copper fasteners belong in 7415.29.
Goods of Mexican origin that qualify under USMCA rules of origin — including meeting applicable tariff-shift and regional-value-content requirements — may be eligible for preferential duty treatment. Importers should obtain a valid USMCA certification of origin from the Mexican supplier and verify that the specific product meets the applicable rule before claiming preference.
