7310.21.00.70 - Containers of a circular cross section, of a capacity not exceeding 11.4 liters, of a kind used for aerosols

This HTS category, 7310.21.00.70, specifically addresses containers constructed from iron or steel, designed with a circular cross-section. These containers are intended for general use, excluding those for compressed or liquefied gases. Crucially, they have a capacity not exceeding 11.4 liters and are of the type commonly employed for aerosol products. This includes, but is not limited to, smaller aerosol cans for personal care products, cleaning agents, or spray paints.

Distinguishing this subcategory from its siblings, 7310.21.00.25 covers similar circular steel containers but with a larger capacity range, from 11.4 liters up to 26.6 liters, and is generally used for the conveyance of goods. The "Other" sibling category, 7310.21.00.75, serves as a residual catch-all for cans intended to be closed by soldering or crimping that do not fit the specific criteria of this aerosol-focused classification or the larger conveyance containers.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. Therefore, classification into 7310.21.00.70 relies solely on the precise physical attributes of the container: its iron or steel construction, circular cross-section, a capacity not exceeding 11.4 liters, and its intended application as an aerosol container.
