HSN code 7309 pertains to large reservoirs, tanks, vats, and similar containers made of iron or steel, designed for holding materials other than compressed or liquefied gases. Crucially, these containers must have a capacity exceeding 300 litres. They might feature linings or insulation for material preservation but should not be equipped with mechanical or thermal equipment. This 4-digit heading is vital for procurement teams sourcing bulk storage solutions for water, chemicals, oils, and other industrial liquids or solids. Understanding HSN 7309 ensures correct customs classification, accurate GST calculation, and compliance with trade regulations in India for significant storage infrastructure. MetaleMart provides the base raw materials like MS and SS plates and coils essential for fabricating items classified under HSN 7309.
What HSN 7309 Covers
HSN 7309 encompasses a broad range of stationary, bulk storage containers fabricated from iron or steel. The defining characteristics are a capacity exceeding 300 litres and the intended use for materials *other than* compressed or liquefied gases. This includes large-scale reservoirs for water storage (industrial, agricultural, residential buildings), vats for holding chemicals (provided they are not gases), tanks for storing fuel oil, molasses, or other industrial liquids and semi-liquids. The description explicitly allows for these containers to be lined (e.g., with rubber or epoxy for corrosion protection) or heat-insulated (e.g., with polyurethane foam for temperature maintenance). However, a critical exclusion is the presence of "mechanical or thermal equipment." This means the container itself should be a passive storage unit; items like integrated pumps, heating coils, agitators, or complex control systems would typically move the classification elsewhere. It's important to distinguish HSN 7309 from smaller containers (under 300L), containers specifically designed for gases (covered under 7311), or pressure vessels that require adherence to specific engineering codes beyond basic storage. Procurement teams must ensure the fabricated item meets the capacity and functional criteria to fall correctly under this heading.Common Materials & Grades for HSN 7309 Fabrication
- Mild Steel (MS): IS 2062 Grade E250 (most common for general-purpose water and oil tanks), IS 2002. Used for its weldability and cost-effectiveness.
- Stainless Steel (SS): SS 304 / 1.4301 (versatile, good corrosion resistance for chemicals and food-grade applications), SS 316 / 1.4401 (superior corrosion resistance for aggressive chemicals). Essential when product purity or resistance to harsh environments is required.
- Boiler Quality Plates: Such as IS 2002, used for tanks subjected to higher temperatures or pressures, though 7309 excludes true pressure vessels.
- Metal Shapes: Primarily sourced as plates, sheets, and coils from suppliers like MetaleMart, which are then custom-formed and welded into the final tank shape.

- Agricultural storage (e.g., large liquid fertilizer tanks)
GST Rate (Indicative)
HSN 7309 typically falls under the 18% GST slab. This applies to most fabricated steel products not specified elsewhere. However, specific material compositions or specialized uses might attract different rates. Always verify the exact GST rate applicable to your specific purchase on the official CBIC portal.

Frequently Asked Questions about HSN 7309
What exactly does HSN 7309 cover, and what are its key exclusions?
HSN 7309 covers storage tanks and reservoirs made of iron or steel with a capacity exceeding 300 litres, intended for storing various materials (excluding compressed or liquefied gases). These containers may be lined or insulated but must not have mechanical or thermal equipment fitted. It is crucial to distinguish this from containers for gases (HSN 7311) or smaller general-purpose containers. Consult your CHA for specific classifications.
What are the common materials, shapes, capacities, and MOQs for HSN 7309 products in India?
For HSN 7309, typical materials are Mild Steel (like IS 2062), Stainless Steel (SS 304, SS 316), and sometimes specialised alloys depending on the stored material. Shapes are primarily custom-fabricated tanks and vats, not standard metal forms. Common capacities range from 500 litres to over 50,000 litres. Minimum Order Quantities (MOQs) are usually project-based, often involving full fabrication orders rather than per-piece sales for smaller tanks.
Can you provide specific examples of industrial uses and common confusions for HSN 7309?
HSN 7309 is for bulk storage containers. Examples include large water tanks for industrial plants, chemical storage vats (non-gas), fuel oil reservoirs, and raw material holding vessels. It excludes portable containers, smaller storage units under 300L, tanks for compressed gases (HSN 7311), and pressure vessels requiring specialised design codes. Always verify with customs.
Who are the typical suppliers for HSN 7309 products in India, and how does MetaleMart fit in?
The primary suppliers for HSN 7309 are specialised fabrication workshops and engineering firms across India, particularly in industrial hubs like Mumbai, Pune, Chennai, Ahmedabad, and Delhi NCR. MetaleMart lists the raw materials (MS, SS plates, coils) used in fabricating these tanks, which are procured separately. While MetaleMart doesn't sell the finished tanks, it is a key source for the base metals required by fabricators.
