HS code for Steel threaded fittings: 7307.92

Iron or steel, tube or pipe fittings, threaded elbows, bends and sleeves, other than stainless steel.

Classification of steel threaded fittings under HS 7307.92

Steel threaded fittings are classified under HS code 7307.92 because they fall within Chapter 73, which covers articles of iron or steel. Specifically, heading 7307 is designated for tube or pipe fittings, such as couplings, elbows, and sleeves. The classification process follows the General Rules of Interpretation (GRI), specifically GRI 1 and GRI 6. Under GRI 1, the heading is determined by the terms of the headings and any relative section or chapter notes. Since these items are clearly pipe fittings made of steel, 7307 is the appropriate heading. Moving to the subheading level under GRI 6, 7307.92 is selected because it specifically identifies fittings that are threaded and made of iron or non-alloy steel, excluding stainless steel. The threading is a critical technical feature that distinguishes these products from butt-welded or flange-type fittings. Furthermore, the material composition must be iron or non-alloy steel; if the fitting were made of stainless steel, it would be classified under a different subheading within the same heading.

Covers

  • Victaulic threaded fittings
  • Parker Hannifin threaded fittings

Codes often confused with 7307.92

Common mistake. A frequent misclassification occurs with HS code 7307.22, which is reserved for threaded elbows, bends, and sleeves made specifically of stainless steel. Importers often confuse the two based on the appearance of the metal, but the metallurgical composition is the deciding factor. Another common error involves HS code 7307.11, which covers fittings made of cast iron. If the fitting is forged or machined from non-cast steel, 7307.11 is incorrect. Additionally, 7307.91 is sometimes used erroneously; however, that code is specifically for flanges, not threaded elbows or sleeves.

Top exporters and importers of HS 730792 (the code used for steel threaded fittings), 2025

In 2025, the largest exporter of HS 730792 (the code used for steel threaded fittings) in UN Comtrade data was China, with 15% of world exports; the largest importer in UN Comtrade data was the United States, with 29% of world imports.

How these figures are built

109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
