Plastics, stoppers, lids, caps and other closures, for the conveyance or packing of goods.
Classification of plastic stoppers under HS 3923.50
Plastic stoppers are classified under HS code 3923.50 because they are primary closures used for the conveyance or packing of goods. Chapter 39 of the Harmonized System covers plastics and articles thereof, while heading 3923 specifically addresses articles for the conveyance or packing of goods, of plastics. Subheading 3923.50 is dedicated to stoppers, lids, caps, and other closures. The classification is determined by the primary function of the item as a sealing mechanism for containers such as bottles, jars, or flasks used in industrial or commercial packaging. If the stopper is designed to be part of a finished retail product's packaging, it remains here. The material composition must be predominantly plastic to qualify under this heading. This classification follows General Interpretative Rule (GRI) 1, which dictates that classification is determined by the terms of the headings and any relative section or chapter notes. Since 3923 specifically mentions closures for packing, it takes precedence over more general plastic headings. Furthermore, GRI 6 is applied to determine the specific subheading 3923.50 based on the product's physical characteristics as a closure device rather than a container body.

Codes often confused with 3923.50
Common mistake. A frequent error is classifying these items under HS code 3924.90, which covers household articles and hygienic or toilet articles of plastics. While a stopper might be used in a household setting, if its primary role is the conveyance or packing of goods, 3923.50 is correct. Another confusion arises with HS code 3926.90, the catch-all category for other articles of plastic. However, because 3923 specifically describes closures, it must be used according to the principle of specificity. Rubber stoppers are also often confused with plastic ones, but they belong in heading 4016.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
