What HS code 7311 covers
This heading is about the content, not the size. If a container is made of iron or steel and is built to hold gas that is squeezed under pressure or turned into liquid, it belongs here. Steel gas cylinders are the common example.
The code comes from the Harmonized System, the tariff classification kept by the World Customs Organization. Customs offices use it on declarations, so the same product can be followed across borders. That is why shipment records are searched by code.
HS code 731100 and national tariff lines
The international system stops at six digits. Many countries add extra digits for their own tariff lines, so a local invoice may show a longer number than 731100. The first six digits stay the same. In India the same system is called HSN, so you may see people search for HSN code 7311.
We do not list duty or GST rates here. They differ by country and they change. Check the tariff of the country you trade with. If you are not sure your product fits, try the HS code classifier.
7311 vs 7309 and 7310: choosing the right heading
Three neighbouring headings cover steel containers. The first split is what goes inside. The second split is size.
A steel tank for oil or water goes to 7309 or 7310, depending on capacity. A container for compressed or liquefied gas goes to 7311, large or small. Size only matters for the other two headings.
- 7309: reservoirs, tanks and vats for any material except compressed or liquefied gas, with capacity above 300l.
- 7310: tanks, casks, drums, cans and boxes for any material except compressed or liquefied gas, with capacity up to 300l.
