HS Code for Gas cylinders
HS code 7311.00 is the designated classification for containers for compressed or liquefied gas made of iron or steel. This heading is specific to the material (ferrous metal) and the intended use (containing pressurized gas). Under the Harmonized System, containers are often classified by their material composition. Therefore, 7311.00 covers a wide range of steel vessels, from small portable canisters to large industrial cylinders. The classification remains consistent regardless of the specific gas contained (e.g., oxygen, nitrogen, propane, or refrigerant), provided the container is designed to withstand pressure. The construction method—whether seamless or welded—does not change the four-digit heading but may influence national-level tariff lines. This code is vital for the global trade of energy products and industrial gases, ensuring that safety-regulated pressure vessels are correctly identified for customs and safety inspections. The container must be designed for a pressure exceeding 0.5 bar to generally be considered a pressure vessel under this heading.
Products Included
- Seamless steel cylinders for high-pressure gases
- Welded steel bottles for liquefied petroleum gas (LPG)
- Portable oxygen tanks made of steel
- Refrigerant gas recovery cylinders
- Accumulators for hydraulic systems (if designed as gas containers)
Common Misclassification
A frequent mistake is classifying aluminum gas cylinders under 7311.00. Aluminum containers belong in 7613.00. Furthermore, 7310 is often confused with 7311; however, 7310 is for tanks, casks, and drums for any material (usually liquids or solids) not exceeding 300 liters, whereas 7311 is specifically for compressed or liquefied gas regardless of the volume, provided they are pressure vessels. Additionally, if the cylinder is part of a fire extinguisher, it should be classified under 8424.10.
