HSN code 7311 specifically covers 'Containers for compressed or liquefied gas, of iron or steel.' This heading is crucial for businesses involved in the manufacturing, import, or export of gas cylinders and storage vessels used for industrial gases, fuel gases, and medical gases in India. Procurement teams, accountants, and Customs House Agents (CHAs) rely on this HSN code for correct classification, duty assessment, and GST compliance. Understanding HSN 7311 ensures that the correct tax structure is applied and that trade procedures are followed smoothly. MetaleMart's role is supporting this sector by providing the high-quality steel raw materials and components necessary for producing these vital containment units.
What HSN 7311 Covers
HSN code 7311 specifically deals with containers manufactured from iron or steel that are designed and constructed to hold compressed or liquefied gases. This includes a wide range of products such as:- Industrial Gas Cylinders: Such as those used for oxygen, nitrogen, argon, acetylene, and other industrial applications.
- LPG Cylinders: Commonly used for domestic and commercial cooking gas, as well as welding and other industrial uses.
- Portable Gas Containers: Smaller, transportable vessels designed to safely contain pressurized gases.
- Fixed Storage Vessels: Larger stationary tanks specifically engineered for the storage of liquefied or compressed gases under pressure.
- Containers made from materials other than iron or steel (e.g., aluminium or plastic containers for gases).
- General storage tanks or containers not specifically designed for compressed or liquefied gases (these might fall under HSN 7310 if their capacity does not exceed 300 litres, or HSN 7309 for larger general storage tanks).
- Components of gas containers sold separately, unless they are integral parts sold with the container system.
- Gas regulators, valves, and associated equipment when sold independently might be classified under different HSN codes (e.g., HSN 8481 for taps, cocks, and valves).
Common Materials & Grades for HSN 7311
- Seamless Steel Tubes/Pipes (e.g., 20#, 37Mn, 4140): Used for constructing the main body of high-pressure gas cylinders.
- High-Strength Alloy Steel Plates (e.g., 30CrMoA, 34CrMo4): Essential for cylinder necks, bases, and even fully forged cylinders requiring exceptional durability.
- Carbon Steel Sheets/Plates (e.g., Q235, SA516 Gr.70): Suitable for lower-pressure gas storage tanks and certain types of industrial gas containers.
- Welding Wire/Rods (e.g., ER70S-6): Used in fabricating welded gas containers.
- Steel Forgings: For critical components like valve connections and closures requiring high integrity.

Frequently Asked Questions about HSN 7311
What are common grades of steel used for gas cylinder discs under HSN 7311?
Discs, typically made from 30CrMoA or similar high-strength steel, are used for the base of certain gas cylinders. The specific grade depends on the pressure rating and gas type. Verify compatibility with your cylinder manufacturer.
What types of gas containers are covered by HSN 7311?
HSN 7311 covers cylinders designed for compressed or liquefied gas. This includes portable gas cylinders for industrial gases (like Argon, Nitrogen, Oxygen), fuel gases (LPG, Acetylene), and even larger storage vessels where the primary function is containing compressed gas. It excludes general storage tanks not specifically designed for compressed/liquefied gases.
Does MetaleMart sell finished gas cylinders under HSN 7311?
While MetaleMart doesn't directly sell finished gas cylinders, we supply the high-quality steel raw materials (like specific grades of Carbon Steel and Alloy Steel) that are essential for manufacturing these containers. Buyers looking to produce cylinders or components should consult our catalog for suitable steel plates, tubes, or bars.
Do accessories or integrated parts of gas containers fall under HSN 7311?
Yes, steel components like valves, regulators, and pressure relief devices *integrated* into the gas container system might fall under different HSN codes if sold separately. However, if they are integral parts supplied *with* the container and essential for its function as a compressed gas unit, they are generally considered part of the HSN 7311 classification. When in doubt, consult a CHA.
