HSN code 7307 pertains to 'Tube or pipe fittings (for example, couplings, elbows, sleeves), of iron or steel' in India. This heading is critical for procurement teams, accountants, and Custom House Agents (CHAs) dealing with infrastructure, manufacturing, and processing industries. Understanding this HSN is vital as it differentiates standard pipes (covered elsewhere, e.g., 7303-7306) from the essential connecting components. Correct classification ensures accurate GST calculation and customs clearance. MetaleMart’s extensive catalog of steel and alloy pipes necessitates a clear understanding of their corresponding fittings under HSN 7307 for seamless project execution and supply chain management.
What HSN 7307 Covers
HSN 7307 is the classification for all finished tube and pipe fittings specifically manufactured from iron or steel. This encompasses a wide variety of components used to join pipes, change direction, branch off, or terminate a piping system. Examples include threaded or socket-weld elbows, tees, crosses, reducers (concentric and eccentric), couplings, unions, caps, and flanges. The key criterion is that the article must be a fitting designed for iron or steel tubes/pipes and made of iron or steel itself. Items like malleable cast iron fittings fall under HSN 7307, whereas fittings made from other metals like brass (HSN 7419), copper (HSN 7412), or aluminium (HSN 7609) are classified separately. Plastic fittings would fall under HSN 3917. This code is distinct from the pipes themselves, which are classified under HSN 7303, 7304, 7305, and 7306.ONS: Exclusions include items that are part of machinery (Chapter 84/85) or structural components (HSN 7308).Common Materials & Grades
- Mild Steel (MS) Fittings: Including elbows, tees, and couplings in grades like IS 2062, often galvanized or black for general piping.
- Stainless Steel (SS) Fittings: Such as SS 304/304L and SS 316/316L elbows, flanges, and unions for corrosive environments.
- Carbon Steel Fittings: For high-pressure applications, including forged steel elbows and sockets in grades like ASTM A105.
- Galvanized Iron (GI) Fittings: Commonly used for water distribution and low-pressure systems, including GI elbows and sockets.
- Steel Sleeves and Couplings: Used for pipe repair or joining, available in various steel grades.
