4503.10 - Corks and stoppers:

This HTS category, 4503.10, specifically covers stoppers and corks made from natural cork. These are items primarily designed to seal or close containers, such as bottles, jars, or other receptacles. The defining characteristic is their material composition – natural cork – and their function as closures. Examples include traditional wine corks, stoppers for spirits, or decorative cork closures for various craft and packaging purposes.

Distinguishing this category from its sibling, 4503.90 (Other), is crucial for accurate classification. While 4503.90 encompasses all other articles made of natural cork that are not stoppers or corks, 4503.10 is exclusively for those items that serve the direct purpose of sealing or plugging. This distinction hinges on the intended use and primary function of the cork article.

Within this category, further subdivision is provided by 4503.10.60.00, which specifically addresses tapered corks and stoppers where the thickness, or length, is greater than the maximum diameter. This level of detail allows for finer distinctions based on the physical geometry of the cork, aiding in the precise classification of such articles based on their dimensional characteristics.
