4503.10.30.00 - Wholly of cork, of a thickness (or length) greater than the maximum diameter

This HTS category, 4503.10.30.00, specifically classifies natural cork stoppers that are tapered and designed such that their thickness (or length, when tapered) exceeds their maximum diameter. These are typically cylindrical or conical in shape, with a wider end that tapers to a narrower end, intended to be inserted into the opening of a container, such as a bottle, to form a seal. The defining physical characteristic is the proportion of the stopper's dimensions, where the tapering dimension is greater than the widest part of the stopper.

This designation distinguishes these stoppers from other cork stoppers classified under 4503.10.40.00, which would encompass tapered cork stoppers where the thickness (or length) is not greater than the maximum diameter, or other types of natural cork stoppers that do not fit the specific dimensional criteria outlined here. The intent is to isolate stoppers with a particular geometric form and proportion for statistical and tariff purposes.

As this is a leaf node within the HTS classification, there are no further subcategories. All articles meeting the description of "Wholly of cork, of a thickness (or length) greater than the maximum diameter" and functioning as stoppers will fall under this specific code, provided they are made entirely of natural cork.
