Product classification
HS code for LPG cylinders: 7311.00
Containers for compressed or liquefied gas, of iron or steel.
Classification of LPG cylinders under HS 7311.00
LPG cylinders are classified under HS code 7311.00, which covers containers for compressed or liquefied gas made of iron or steel. Unlike the fuel they contain, which is classified in Chapter 27, the containers themselves are classified based on their material composition and their specific function as pressure vessels. Chapter 73 is dedicated to articles of iron or steel, and heading 7311 is the specific destination for gas cylinders. The classification applies regardless of the cylinder's capacity, provided it is a transportable container designed to withstand internal pressure. This includes the heavy-duty steel bottles used for domestic cooking, portable camping gas canisters made of steel, and larger industrial tanks. The classification is driven by the "essential character" of the item as a metal container designed for high-pressure storage. Customs authorities look for compliance with pressure vessel standards and the material of construction (iron or steel) to confirm this classification.

Codes often confused with 7311.00
Common mistake. LPG cylinders are sometimes misclassified under 7310, which covers tanks, casks, and drums for liquids or solids, but specifically excludes those for compressed or liquefied gas. Another common error is classifying them under 8481 if they are imported with valves attached; however, the cylinder remains the primary article under 7311.00, while the valve is considered an accessory or part of the assembly.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
