HS code for Cast steel fittings: 7307.19

Iron or steel, cast fittings, other than of non-malleable cast iron.

Classification of cast steel fittings under HS 7307.19

Cast steel fittings are classified under HS code 7307.19, which falls within Chapter 73 of the Harmonized System, covering articles of iron or steel. Specifically, heading 7307 applies to tube or pipe fittings such as couplings, elbows, and sleeves. The classification logic for 7307.19 is determined by two primary factors: the material composition and the manufacturing process. These fittings are made of steel, which is distinguished from iron by its carbon content and other alloying elements, and they are produced through the casting process. Under the subheadings of 7307, the code 7307.11 is reserved for non-malleable cast iron, while 7307.19 serves as the residual category for all other cast fittings, including those made of cast steel or malleable cast iron. To be classified here, the fittings must be in their finished or semi-finished state, having been formed by pouring molten metal into a mold. This classification is essential for ensuring that the correct customs duties are applied, as steel fittings often carry different regulatory requirements compared to forged or machined alternatives.

Codes often confused with 7307.19

Common mistake. A frequent point of confusion involves distinguishing between cast fittings (7307.19) and forged fittings, which are classified under 7307.91 (flanges) or 7307.99 (other). Forged fittings are shaped through mechanical pressure and heat rather than casting. Additionally, 7307.11 is often incorrectly used for steel fittings; however, 7307.11 is strictly for non-malleable cast iron. Importers must also distinguish these from valves, which are classified under heading 8481.

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).
