3923.30.00.90 - Other

This HTS category, HTS 3923.30.00.90, encompasses "Other" carboys, bottles, flasks, and similar articles made of plastics, when their capacity exceeds 50 ml. These items are designed for the conveyance or packing of goods, fulfilling the broader purpose of Chapter 3923. The defining characteristic for inclusion here is the volume of the container.

This specific classification distinguishes itself from its sibling, 3923.30.00.10, which is reserved for similar plastic containers with a capacity *not exceeding* 50 ml. Therefore, any plastic bottle, flask, or similar article intended for carrying or packaging goods that holds more than 50 ml would fall under this "Other" designation, provided it meets the general criteria of the parent code.

As this is a leaf node within the HTS structure, there are no further subcategories. Classification within 3923.30.00.90 relies on the positive identification of a plastic container fitting the description of a carboy, bottle, flask, or similar article for conveyance or packing, and crucially, having a capacity greater than 50 ml. Examples might include larger beverage bottles, jerry cans, or laboratory flasks of significant volume.
