Product classification

HS code for Malleable iron fittings: 7307.19

Iron or steel, cast fittings, other than of non-malleable cast iron.

Classification of malleable iron fittings under HS 7307.19

Malleable iron fittings are classified under HS code 7307.19 because they are cast articles of iron or steel that have undergone a specific heat treatment process to improve their mechanical properties. Unlike standard grey cast iron, which is brittle and prone to fracturing under tension, malleable iron is annealed to transform the carbon structure into graphite nodules. This process makes the material more ductile and resistant to cracking under stress, which is essential for plumbing and industrial piping systems. The Harmonized System categorizes these products under Chapter 73, which covers articles of iron or steel, specifically within the heading for tube or pipe fittings. Subheading 7307.19 is reserved for "other" cast fittings that do not fall under the non-malleable category. This classification is determined by the manufacturing process of casting followed by heat treatment, ensuring the product meets the technical definition of malleable iron as opposed to standard cast iron or forged steel.

Codes often confused with 7307.19

Common mistake. These fittings are frequently confused with HS code 7307.11, which is specifically for non-malleable cast iron fittings. The distinction lies in the ductility of the metal; non-malleable fittings are typically used for low-pressure drainage, while malleable fittings are for pressurized systems. Additionally, they may be confused with 7307.21 (stainless steel fittings) or 7307.91 (forged steel flanges), which are distinguished by their material composition and manufacturing method rather than the casting and annealing process.

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).

Questions about malleable iron fittings

What is the HS code for Malleable iron fittings?

The HS code for Malleable iron fittings is 730719 (Iron or steel; cast fittings, other than of non-malleable cast iron). The primary HS code for malleable iron fittings is 7307.19, which covers cast fittings of iron or steel other than non-malleable cast iron.

How do I classify Malleable iron fittings for customs?

Malleable iron fittings is classified under HS code 730719 — Iron or steel; cast fittings, other than of non-malleable cast iron. This is a 6-digit subheading level code.

What is the difference between 7307.11 and 7307.19?

HS code 7307.11 is for non-malleable cast iron (brittle), whereas 7307.19 is for malleable cast iron which has been heat-treated for ductility.

Which countries are the top exporters of malleable iron fittings (HS 730719)?
