U.S. exports of threaded articles of iron or steel (nesoi) (HS 731819) totaled $26.3M in July 2026.
Importers of Threaded Articles of Iron or Steel (NESOI) paid $6.8M in duties in July 2026 — an effective duty rate of 60% on $11.3M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: July 2026 dataClassified under a single 10-digit line (7318190000), this residual heading captures threaded iron or steel articles that do not fit the more specific fastener categories — such as threaded inserts, threaded couplings, and other engineered threaded components used in industrial and mechanical assemblies. China is the leading supplier, followed by Germany, Taiwan, the United Kingdom, and India, reflecting a supply base that spans both high-volume commodity production and precision-engineered specialty parts. Because this is a catch-all classification, CBP may challenge the heading if a product more specifically fits a named fastener category, making pre-import classification review particularly valuable.

Products commonly classified here include threaded inserts (e.g., helical coil inserts, press-fit inserts), threaded pipe couplings of iron or steel not covered by Chapter 73 pipe fittings headings, and other engineered threaded components that lack a dedicated HTS line. The key test is that the article must be threaded and of iron or steel, and must not be more specifically described by another heading in Chapter 73.
If CBP questions whether an article belongs in a named fastener heading (e.g., screws or bolts under 731815) rather than the residual 731819, the importer should provide technical drawings, product specifications, and end-use documentation demonstrating that the article does not meet the definition of any specifically named fastener type. A binding ruling request to CBP before importation is the most reliable way to resolve classification uncertainty for novel or complex threaded components.
