HS Code for Malleable iron fittings
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.
Products Included

Common Misclassification
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.
FAQ
What is the HS code for malleable iron fittings?
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.
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.
