Oxygen cylinder Hs Code

Oxygen cylinder harmonized system code

Product Overview Oxygen cylinders classified under HS Code 731100 are defined as seamless or welded steel gas cylinders specifically designed for the containment and transportation of compressed oxygen gas. These cylinders typically feature high-strength carbon steel or alloy steel construction, with capacities ranging from 2 to 50 liters and pressure ratings commonly between 150 to 300 bar, ensuring safe storage under high pressure. The manufacturing process involves precision forging, heat treatment, and rigorous non-destructive testing (NDT) to meet international quality standards such as ISO 9809 and DOT specifications. Within HS Code 731100, subcategories differentiate cylinders by manufacturing method (seamless vs. welded), intended gas type (medical, industrial), and cylinder size/class. Commercially, these oxygen cylinders are predominantly utilized in food service industries for modified atmosphere packaging and preservation, in retail for medical and welding applications, and in industrial processing for combustion and oxidation processes. Their market positioning is reinforced by durability, compliance with safety regulations, and compatibility with global valve fittings, offering a reliable solution for international supply chains. HS Code Classification & Trade Specifications The complete HS Code for oxygen cylinders under this category is 7311.00, where Chapter 73 covers “articles of iron or steel,” Heading 7311 designates “containers for compressed or liquefied gas,” and Subheading 00 specifies gas cylinders including those for oxygen. Classification under 731100 is justified by the product’s metallic composition, design for pressurized gas containment, and exclusion from other specialized cylinders such as those for liquefied petroleum gas. Trade considerations emphasize packaging in reinforced wooden crates or steel frames to mitigate damage during transit, with preservation methods including corrosion-resistant coatings and desiccant use to prevent moisture-related degradation. Shipping protocols conform to international standards such as the IMDG Code and ADR regulations for hazardous materials, ensuring compliance with safety and environmental norms. Quality standards align with ISO 11120 and ISO 9809 series, mandating strict dimensional tolerances, material traceability, and periodic inspection intervals to satisfy WTO and customs documentation requirements, facilitating smooth cross-border trade and regulatory adherence.

Oxygen 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.
