Gas cylinder Hs Code

Gas cylinder harmonized system code

Product Overview Gas cylinders classified under HS Code 731100 are defined as seamless or welded steel containers specifically designed for the storage and transportation of compressed gases. These cylinders are manufactured to comply with stringent industry standards, featuring cylindrical bodies typically constructed from high-strength carbon steel or alloy steel, with capacities ranging from 1 to 50 liters. Key physical specifications include precise wall thickness to withstand internal pressures up to 300 bar, standardized valve fittings, and corrosion-resistant finishes to ensure durability. The HS Code 731100 encompasses a range of subcategories such as seamless gas cylinders (73110010), welded cylinders (73110020), and other pressure vessels suitable for gaseous contents. Commercially, these cylinders are extensively utilized in sectors including food service (e.g., carbon dioxide for beverage carbonation), retail (propane for heating and cooking), and industrial processing (oxygen and nitrogen supply). Their robust design, compliance with international pressure vessel codes (such as ISO 9809), and compatibility with global gas standards position them as essential components in international gas trade, offering reliability and safety in high-pressure gas containment. HS Code Classification & Trade Specifications The gas cylinders fall under the 6-digit HS Code 731100, where Chapter 73 denotes “Articles of Iron or Steel,” Heading 7311 specifies “Containers for compressed or liquefied gas, of iron or steel,” and the Subheading 731100 identifies gas cylinders distinguished by manufacturing method and design. This classification is justified by the cylinders’ construction material, purpose for containing compressed gases, and compliance with international manufacturing standards. Trade professionals should note that packaging typically involves secure crating or palletization to prevent mechanical damage during transit, with preservation methods including anti-corrosion coatings and pressure testing certificates accompanying shipments. Shipping requirements mandate adherence to the International Maritime Dangerous Goods (IMDG) Code and proper labeling for hazardous materials. Quality standards applicable include ISO 9809 for seamless cylinders and ISO 11119 for welded types, ensuring uniformity in pressure resistance and material integrity. These specifications align with World Trade Organization (WTO) guidelines and customs documentation protocols, facilitating smooth customs clearance and minimizing classification disputes in cross-border transactions.

Gas cylinder Chapter Note

1.- In this Chapter the expression “cast iron” applies to products obtained by casting in which iron predominates by weight over each of the other elements and which do not comply with the chemical composition of steel as defined in Note 1 (d) to Chapter 72. 2.- In this Chapter the word “wire” means hot or cold-formed products of any cross-sectional shape, of which no cross-sectional dimension exceeds 16 mm.
