Plain-language overview
Use HS-6 731100 when importing or exporting containers made of iron or steel designed to hold compressed or liquefied gases. For instance, a shipment of steel gas cylinders used in welding applications would fall under this code.
This code specifically covers containers such as gas cylinders, which are crucial for safely storing and transporting gases under pressure. In contrast, HS-6 731200 refers to similar containers but made of aluminum, which may be used in different applications.
When classifying under this heading, it’s important to note that the focus is on the material and the intended use of the container. Containers that are not specifically designed for gas storage, like general-purpose steel drums, would not qualify under this HS-6.
If you're dealing with containers that are designed to hold gases at high pressures, ensure they meet the safety and regulatory standards applicable in your country, as these can affect import/export processes.
