3923.50.00.00 - Stoppers, lids, caps and other closures

This HTS category, 3923.50.00.00, specifically covers stoppers, lids, caps, and other closures designed for use with articles for the conveyance or packing of goods, all manufactured from plastics. This encompasses a wide array of items such as screw caps for bottles, pop-off lids for containers, cork-like stoppers made of plastic, and tamper-evident seals. The primary function of these items is to seal or close an opening to prevent leakage, contamination, or spillage, or to secure the contents within a larger packaging item.

This category is distinct from its sibling categories which focus on the primary containment vessels or structural packing elements. For instance, 3923.10 covers rigid containers like boxes and crates, while 3923.30.00 encompasses bottles, carboys, and flasks themselves. Similarly, 3923.40.00 deals with spools, cops, and bobbins used for winding materials. Therefore, 3923.50.00.00 is specifically for the components that complete the seal of these or other plastic packing articles, not the articles themselves.

As this is a leaf node, there are no further subcategories. Classification within 3923.50.00.00 is determined by the material (plastics) and the specific function as a closure for packaging or conveyance articles. The diversity of shapes and sizes of these closures is broad, ranging from simple snap-on caps to complex child-resistant closures or specialized dispensing caps, all falling under this singular designation.
