Product classification
HS code for Cast iron castings: 7325.10
Iron, articles of non-malleable cast iron.
Classification of cast iron castings under HS 7325.10
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.

Codes often confused with 7325.10
Common mistake. 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.

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).
