HSN code 7308 in India encompasses a wide array of structural components and assemblies made from iron or steel, specifically prepared for use in construction and infrastructure projects. It covers everything from major bridge sections and bridge-parts to lock-gates, towers, lattice masts, roofs, roofing frameworks, and even doors, windows, and their associated frames and thresholds. This HSN is crucial for procurement teams sourcing materials for building construction, industrial sheds, bridges, and other infrastructure development. MetaleMart's offerings of steel plates, sheets, structural sections like beams and channels, and pipes form the foundational materials for many items classified under 7308. Understanding this HSN ensures correct customs classification and GST calculation for imported or domestically sourced structural steel.
What HSN 7308 Covers
HSN 7308 is dedicated to articles of iron or steel that form part of structures. This includes a broad spectrum of items, from large-scale civil engineering components like bridge sections and lock-gates to industrial necessities such as towers and lattice masts. Roofing systems, including frameworks and complete roofing structures, fall under this code. Furthermore, HSN 7308 encompasses doors, windows, and their essential parts like frames, thresholds, and shutters, provided they are made of iron or steel. Balustrades and pillars or columns, crucial for both support and aesthetics in architecture, are also classified here. The key criterion is that these iron or steel items must be **prepared for use in structures**. This preparation can involve cutting, shaping, bending, welding, or assembly. The heading explicitly excludes prefabricated buildings classified under HSN 9406. It also excludes basic forms of iron or steel like ingots, bars, or rods *before* they are shaped or prepared for structural purposes, which would fall under earlier headings in Chapter 72 or 73. Items not made of iron or steel, even if structurally similar (e.g., aluminium windows), are classified under their respective material headings. MetaleMart provides the base materials (like plates, standard sections, and pipes) that are subsequently processed and used to create the finished structures or parts falling under 7308.Common Materials & Grades (HSN 7308)
- Mild Steel (MS) Structural Sections (IS 2062): Beams (I, H), Channels (C), Angles (L) – fundamental for building frameworks.
- Galvanised Steel Structures: MS sections coated with zinc for corrosion resistance, used in exposed environments.
- Steel Plates & Sheets (IS 2062): Used for fabricating custom structures, reinforcements, and sheet piling.
- Steel Pipes & Tubes (IS 1239, IS 3074): Used for scaffolding, structural framing, and pipe racks.
- Stainless Steel Structural Sections (e.g., SS 304, SS 316 grades): For corrosive environments where standard steel won't suffice, like chemical plants or coastal structures.
- Fabricated Steel Trusses & Roofs: Pre-engineered components for industrial and commercial building roofs.
- Steel Doors & Window Frames: Ready-to-install frames for industrial and commercial buildings.
- Steel Balustrades & Pillars: Structural elements for balconies, staircases, and building support.

GST Rate (Indicative)
Most items classified under HSN 7308, which covers structures and parts of structures of iron or steel, typically fall within the 18% GST slab. However, this can vary based on the specific product and its intended use. Always confirm the exact GST rate on the official CBIC portal.

Frequently Asked Questions about HSN 7308
What specific types of structures and parts are covered under HSN 7308?
For HSN 7308, structures like gates, towers, roofing frameworks, and pillars/columns made from iron or steel are covered. This includes pre-fabricated sections of bridges, lock gates, and lattice masts. Doors, windows, their frames, thresholds, and balustrades are also included when made of iron or steel. Essentially, any prepared iron or steel component intended for structural use falls under this HSN unless it constitutes a prefabricated building under 9406.
What is the difference between raw metals for structures and HSN 7308?
HSN 7308 primarily deals with finished or semi-finished iron and steel articles prepared for structural applications. This typically includes items like steel beams, columns, scaffolding, transmission towers, roof trusses, and parts for bridges. While MetaleMart offers raw materials like plates and sections, HSN 7308 focuses on these materials once they are shaped, cut, or assembled for building and infrastructure projects. It's crucial to distinguish between raw metal forms (often under Chapter 72 or other relevant headings) and their structural end-uses covered here.
What items are *excluded* from HSN 7308?
HSN 7308 covers structural components of iron or steel. It excludes prefabricated buildings (HSN 9406). Also, pure iron or steel in basic forms like ingots, bars, rods, or shapes *not yet prepared for structures* would fall under other HSN codes (e.g., 72 or 7301-7307). Finished goods like doors and windows made of materials other than iron or steel (e.g., aluminium, plastic) would also be classified elsewhere.
What is the typical GST rate for HSN 7308?
The typical GST rate band for HSN 7308 is 18%. However, specific items might fall under different slabs depending on their exact nature and application. Always verify the applicable GST rate on the official CBIC portal before making any procurement decisions.
