7010.20 - Stoppers, lids and other closures:

This HTS classification covers stoppers, lids, and other closures specifically made of glass, intended for use with glass containers. These items serve the essential function of sealing or securing the contents of various glass receptacles, such as bottles, jars, and flasks, preventing leakage or contamination and facilitating their conveyance or packing. The scope is limited to closures that are themselves glass articles.

While the parent category (7010) encompasses a range of glass containers and their closures, this specific subheading (7010.20) is dedicated exclusively to the closures themselves, distinguishing them from the primary containers they are designed to seal. It stands apart from sibling categories like "Ampoules" (7010.10.00.00), which are complete glass containers, and "Other" (7010.90), which would cover glass containers not otherwise specified.

The subcategories within 7010.20 further refine the classification based on the manufacturing process. "Produced by automatic machine" (7010.20.20.00) applies to closures mass-produced using automated equipment, which is typical for many common types of stoppers and lids. Conversely, "Other" (7010.20.30.00) would encompass glass closures manufactured through manual or less automated methods, or those with unique characteristics not fitting the "automatic machine" criteria.
