Product classification
HS code for Non-malleable cast iron fittings: 7307.11
Cast iron, cast fittings, of non-malleable cast iron.
Classification of non-malleable cast iron fittings under HS 7307.11
Non-malleable cast iron fittings are classified under HS code 7307.11. Chapter 73 covers articles of iron or steel, and heading 7307 is dedicated to tube or pipe fittings, such as couplings, elbows, and sleeves. The classification within this heading is determined by the material and the casting method. Subheading 7307.11 specifically identifies fittings made of non-malleable cast iron, which is commonly known as grey cast iron. This material is characterized by its brittleness and inability to be deformed without cracking, distinguishing it from malleable or ductile iron. These fittings are typically manufactured through sand casting and are used in low-pressure applications, such as sanitary drainage, vent systems, or gravity-fed industrial piping, where the high tensile strength of steel or the flexibility of malleable iron is not required for safety or performance.

Codes often confused with 7307.11
Common mistake. The most common misclassification is with HS code 7307.19, which covers fittings made of malleable cast iron or ductile cast iron. Malleable iron can withstand some deformation and higher pressures, whereas 7307.11 is strictly for the more brittle grey iron. Additionally, if the fittings are made of stainless steel, they must be classified under 7307.21 through 7307.29. Flanges, even if made of non-malleable iron, are sometimes incorrectly placed here instead of the specific flange subheadings like 7307.91 (though 7307.11 specifically covers cast items).
Top exporters and importers of HS 730711 (the code used for non-malleable cast iron fittings), 2025
In 2025, the largest exporter of HS 730711 (the code used for non-malleable cast iron fittings) in UN Comtrade data was China, with 50% of world exports; the largest importer in UN Comtrade data was Germany, with 8.7% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

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).
