HS Code for Cast steel fittings

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.

Common Misclassification

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.

FAQ

What is the HS code for cast steel fittings?

The primary HS code for cast steel fittings is 7307.19, which covers cast tube or pipe fittings of iron or steel, excluding non-malleable cast iron.

How do I distinguish between 7307.11 and 7307.19?

Code 7307.11 is specifically for non-malleable cast iron (brittle iron), whereas 7307.19 includes malleable cast iron and cast steel fittings which have higher ductility and strength.
