HS Code for Cast iron castings

HS code 7325.10 covers articles of non-malleable cast iron. These are products formed by pouring molten iron into a mold where the resulting metal is brittle and cannot be hammered or pressed into shape without cracking. This code is a residual category for iron castings that are not more specifically described elsewhere in the Harmonized System. The classification is driven by the metallurgical property of being "non-malleable," which typically implies a high carbon content (grey iron). If an article is cast but serves a specific function defined in other chapters (such as a pump housing or a valve body), it may be classified based on that function. However, for general industrial or structural castings that do not have a more specific heading, 7325.10 is the correct designation. This includes items used in infrastructure, construction, and general machinery where the specific part is not yet finished enough to be classified as a machine part.

Products Included

Common Misclassification

A frequent error is confusing non-malleable cast iron with malleable cast iron, the latter of which falls under HS code 7325.99. Malleable iron has been heat-treated to improve its ductility. Another common misclassification involves finished parts of machinery. If a casting is clearly identifiable as a part of a specific machine, such as a transmission housing, it should be classified under Chapter 84 or 85 (e.g., 8483 for bearing housings). Additionally, cast iron pipe fittings are excluded from this code and must be classified under 7307.11.

FAQ

What is the HS code for cast iron castings?

The HS code for non-malleable cast iron castings is 7325.10. For malleable cast iron articles, the code is 7325.99.

How do I distinguish between 7325.10 and 7325.99?

The distinction is based on the physical properties of the iron. 7325.10 is for grey/non-malleable iron, while 7325.99 is for malleable or ductile iron that has undergone annealing.
