HS Code 7325.10 – Iron; articles of non-malleable cast iron
HS code 7325.10 is the 6-digit subheading for iron, articles of non-malleable cast iron. It is used for manhole covers, drain grates, counterweights, machine bases and pipe fittings (non-malleable cast iron).
What HS 7325.10 covers
This code specifically covers articles made from non-malleable cast iron, a material known for its high compressive strength and wear resistance, but also its brittleness. These articles are crucial in heavy-duty applications across various industries, including infrastructure, machinery, and construction. International trade in non-malleable cast iron articles is driven by global demand for durable, robust components that can withstand significant stress and harsh environments. Major importers typically include countries undertaking large-scale infrastructure projects or those with heavy manufacturing industries, such as the USA, Germany, and India. Exporters are often nations with well-established foundry capabilities and access to raw materials, with China being a dominant player. The trade emphasizes the material's specific properties for industrial and civil engineering applications.

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).
