7310.21.00 - Cans which are to be closed by soldering or crimping

This HTS classification covers metal containers, specifically those made from iron or steel, designed for packaging and transport. The defining characteristic of this category is their method of closure: they are intended to be sealed by either soldering or crimping. This implies a permanent or semi-permanent seal achieved through specific manufacturing processes, differentiating them from containers that might use screw-on lids or other temporary closure mechanisms. The scope extends to containers with a capacity not exceeding 300 liters, which are not fitted with any mechanical or thermal equipment.

Within the broader group of containers not exceeding 50 liters, this specific code (7310.21.00) is distinguished from its sibling category, 7310.29.00, which encompasses "Other" containers of less than 50 liters that do not meet the soldering or crimping closure criteria. Therefore, if a container of less than 50 liters is designed to be sealed by soldering or crimping, it falls under 7310.21.00, whereas other types of closures would lead to classification under the "Other" sibling.

The subcategories within 7310.21.00 further refine the classification based on specific dimensions and intended uses. For example, containers designed for aerosols, typically with a smaller capacity not exceeding 11.4 liters and a circular cross-section, are detailed under 7310.21.00.70. Similarly, containers of a circular cross-section with a capacity between 11.4 liters and 26.6 liters, frequently used for the conveyance of various goods, are specifically classified under 7310.21.00.25. The existence of a further "Other" subcategory (7310.21.00.75) allows for the classification of items meeting the primary criteria but not falling into the more specific subcategories.
