HS Code for Cast iron pipe fittings
Cast iron pipe fittings fall under HS code 7307.11. These components are used to join pipes, change the direction of flow, or adapt pipe sizes within a piping system. The classification is restricted to fittings made of non-malleable cast iron. In the Harmonized System, heading 7307 covers all types of tube or pipe fittings of iron or steel. The first level of sub-division is between "cast" and "non-cast" fittings. Within the cast category, the code 7307.11 is specifically for non-malleable iron, which is typically grey cast iron. These fittings are commonly used in sanitary drainage, waste, and vent systems where high pressure or high ductility is not required. The classification is determined by the manufacturing process (casting) and the metallurgical properties of the iron used, ensuring that brittle grey iron fittings are distinguished from more flexible malleable iron versions.

Common Misclassification
Cast iron pipe fittings are most often misclassified under 7307.19, which is the code for malleable cast iron fittings. Malleable iron fittings are tougher and can withstand higher pressures, often used in gas or steam lines. Another common error is classifying these under 7307.91 (flanges) or 7307.92 (threaded elbows/sleeves) if the importer does not realize the item is cast. Additionally, if the fitting is made of stainless steel, it must be classified under 7307.21 through 7307.29. It is critical to verify the material grade (grey vs. malleable) before assigning the code.
FAQ
What is the HS code for cast iron pipe fittings?
