9617.00.10.00 - Having a capacity not exceeding 1 liter

This HTS classification covers vacuum flasks, thermal carafes, and other vacuum-insulated vessels specifically designed to maintain the temperature of their contents, with a maximum liquid capacity of 1 liter. These items are intended for personal or portable use, such as for carrying beverages or food. Examples include small thermoses, travel mugs with vacuum insulation, and compact food jars.

The key distinguishing factor for this category is its capacity limit. Unlike its sibling categories, 9617.00.30.00 and 9617.00.40.00, which cover larger capacity vessels (exceeding 1 liter but not exceeding 2 liters, and exceeding 2 liters respectively), this classification is strictly for those with a capacity of 1 liter or less. This distinction is based purely on the volumetric measurement of the vessel.

As this is a leaf node in the HTS structure, there are no further subcategories. Classification within this code is determined by the product meeting the definition of a vacuum flask or vacuum vessel and possessing a capacity not exceeding 1 liter. The presence of glass inners does not affect classification at this level, as the parent category specifically excludes parts other than glass inners.
