About containers for compressed or liquefied gas, of iron or steel

HS code 7311 covers the production of containers for compressed or liquefied gas, made of iron or steel. These containers play a crucial role in the storage and transportation of various industrial and commercial gases, such as oxygen, nitrogen, propane, and natural gas. The demand for these containers is driven by the growing need for efficient and safe gas handling across a wide range of industries, including manufacturing, healthcare, and energy production, making this industry an important component of the broader global economy.

Production process

The production of containers for compressed or liquefied gas typically involves a multi-step process. First, the raw materials, such as steel sheets or plates, are cut and formed into the desired container shapes, often using techniques like stamping, rolling, or welding. The containers are then subjected to heat treatment and other finishing processes to ensure their structural integrity and resistance to pressure. Finally, the containers are fitted with valves, regulators, and other necessary components to enable the safe storage and release of the compressed or liquefied gas.

Production inputs

The main inputs required for the production of HS code 7311 containers include steel or other metal alloys, as well as specialized equipment and machinery for the manufacturing process. This may include cutting tools, welding equipment, heat treatment furnaces, and testing apparatus to ensure the containers meet safety and quality standards. Additionally, the industry relies on a skilled workforce capable of operating the production equipment and adhering to strict safety protocols.

Production outputs

The primary output of the HS code 7311 industry is the production of containers for compressed or liquefied gas, which are then used by a variety of other industries. These containers may be consumed by manufacturers of 2804 Hydrogen, rare gases and other non-metals, 2811 Other inorganic acids and other inorganic oxygen compounds of non-metals, or 2901 Acyclic hydrocarbons, among others, who require efficient and safe storage and transportation solutions for their industrial gases.
