Chapter 73: Articles of iron or steel

Plain-language overview

Use HS-4 7310 when importing or exporting tanks, casks, drums, cans, or boxes made of iron or steel, with a capacity not exceeding 300 liters. For example, if you are shipping steel drums for chemicals, this heading is applicable.

When deciding between the subheadings, consider the capacity of your containers. HS-6 731010 covers containers with a capacity of 50 liters or more but not exceeding 300 liters. If your shipment consists of 200-liter steel drums, this is the correct classification.

For smaller containers, HS-6 731021 is for cans under 50 liters that are designed to be closed by soldering or crimping. If you have a shipment of 20-liter cans for food products, this subheading is appropriate. In contrast, HS-6 731029 applies to other types of containers under 50 liters that do not fit the specific criteria of 731021.
