7612.90.10.40 - With a circular cross section, of a kind used for aerosols

This HTS category, 7612.90.10.40, specifically classifies aluminum cans with a circular cross-section that are designed for use in aerosol applications. These are typically rigid, single-use containers intended to hold propellants and product for dispensing as a mist or foam. The key defining characteristic for this classification is their intended use as aerosol containers, which dictates specific manufacturing and safety standards.

Distinguishing this category from its sibling, 7612.90.10.45 "Other," is crucial. While both fall under aluminum cans of a capacity not exceeding 355 ml, the ".40" subheading exclusively applies to those specifically manufactured or adapted for aerosol dispensing. The ".45" subheading would encompass other aluminum cans of the same capacity that are not intended for aerosol use, such as those for food, beverages, or other general-purpose packaging.

As this is a leaf node, there are no further subcategories to introduce. Therefore, the focus for classification under this code rests on the definitive criteria of a circular cross-section and their explicit function as containers for aerosols. Importers and exporters should verify that the physical attributes and intended application of their aluminum cans align precisely with the description provided for this subheading to ensure accurate classification and compliance with customs regulations.
