7612.90.10 - Of a capacity not exceeding 20 liters

This HTS category, 7612.90.10, specifically classifies aluminum containers such as casks, drums, cans, boxes, and similar receptacles, including collapsible tubular containers. These items are intended for holding materials other than compressed or liquefied gas. Crucially, this subcategory applies to those with a capacity *not exceeding 20 liters*. The containers may be lined or heat-insulated but must not be equipped with mechanical or thermal apparatus.

This designation distinguishes itself from the sibling category 7612.90.50.00, which covers "Other" aluminum containers under the broader heading of 7612.90. While both fall under "Other" at the 7612.90 level, 7612.90.10 is specifically defined by its capacity limit, whereas 7612.90.50.00 would encompass those exceeding the 20-liter threshold of 7612.90.10 but still within the 300-liter overall limit of 7612.90.

Within this category, further subdivisions exist to refine classification based on capacity. These include subcategories for cans with a capacity not exceeding 355 ml, cans with a capacity exceeding 355 ml but less than 3.8 liters, and a general "Other" category for cans that do not fit the preceding specific capacity ranges. These subcategories ensure precise classification for a wide array of aluminum containers based on their volumetric size.
