4016.99.15.00 - Caps, lids, seals, stoppers and other closures

HTS code 4016.99.15.00 specifically classifies caps, lids, seals, stoppers, and other closures made from vulcanized rubber, excluding hard rubber. These items are designed to seal, close, or protect containers, openings, or conduits. Examples include screw caps for bottles, stoppers for laboratory equipment, rubber seals for automotive parts, and closures for food packaging.

This category is distinct from sibling categories such as containers for packing (4016.99.03.00) which focus on the vessel itself, and household articles (4016.99.05.00) which are general utility items. It also differs from handles and knobs (4016.99.10.00) and pet toys (4016.99.20.00), as the primary function of goods under 4016.99.15.00 is containment and sealing. The key differentiator is the specific function of closure or sealing performed by these rubber articles.

As a leaf node, this classification does not have further subdivisions. Therefore, the classification determination relies on confirming that the article is indeed made of vulcanized rubber (other than hard rubber) and its primary function is to act as a cap, lid, seal, stopper, or other type of closure. Any ambiguity would require further examination of the article's specific design and intended use.
