Gas cartridge Hs Code

Gas cartridge harmonized system code

Product Overview Gas cartridges classified under HS Code 731100 refer to small, sealed containers designed to store and dispense compressed gas, typically carbon dioxide or other inert gases, under high pressure. These cartridges are generally cylindrical, manufactured from corrosion-resistant steel or aluminum alloys, and processed through precision forging and machining to ensure dimensional accuracy and safety compliance. Key physical specifications include standard volumes ranging from 8 to 25 grams of gas content, operating pressures between 50 to 90 bar, and adherence to ISO 11119 for gas cylinder design. The HS Code 731100 encompasses subcategories such as empty gas cartridges, those pre-filled with carbon dioxide, and cartridges containing other non-flammable gases. Commercially, these cartridges are widely utilized in food and beverage industries for soda dispensers and whipped cream canisters, as well as in retail sectors for air rifles and paintball equipment. Their compact design, reliability under pressure, and ease of replacement position them competitively as essential consumables in both industrial and consumer applications. HS Code Classification & Trade Specifications The full HS Code 731100 is structured as follows: Chapter 73 (Iron and Steel), Heading 7311 (Containers for compressed or liquefied gas), and Subheading 731100 (Gas cartridges). This classification is predicated on the product's material composition—primarily steel—and its functional role as a pressure vessel for gas storage under the specified chapter and heading. Trade considerations for gas cartridges include packaging in robust, moisture-resistant cartons or metal crates to prevent physical damage and corrosion during transit. Preservation methods focus on maintaining the integrity of seals and gas purity, often requiring nitrogen flushing or inert gas blanketing prior to sealing. Shipping mandates compliance with the International Maritime Dangerous Goods (IMDG) Code and IATA regulations due to the pressurized contents. Quality standards commonly referenced include ISO 9809 for gas cylinders and relevant ASTM specifications for material properties. Accurate classification under HS 731100 ensures alignment with WTO standards and facilitates seamless customs clearance and tariff determination in international trade operations.

Gas cartridge 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.
