Stoppers, corks, of base metal.
Classification of bottle stoppers under HS 8309.10
Bottle stoppers made of base metal are classified under HS code 8309.10. This classification falls within Chapter 83, which encompasses miscellaneous articles of base metal. Specifically, heading 8309 covers stoppers, caps, and lids (including crown corks, screw caps, and pouring stoppers), capsules for bottles, threaded bungs, bung covers, seals, and other packing accessories of base metal. The subheading 8309.10 is reserved for crown corks, which are the most common type of metal bottle stopper used in the beverage industry. These items are classified here because their primary function is to provide a secure, airtight seal for containers, and they are manufactured from base metals such as steel or aluminum rather than plastic or natural cork. The classification is determined by the material composition and the specific mechanical function of the closure device.

Codes often confused with 8309.10
Common mistake. Bottle stoppers are frequently misclassified under HS code 4503.10, which is reserved for articles of natural cork. While both serve the same purpose, the HS system prioritizes material composition. Another common error is using HS code 3923.50, which covers stoppers, lids, caps, and other closures made of plastics. If the stopper is made of glass, it should be classified under 7010.90. Importers must distinguish between the base metal component and any liners; even if a metal cap has a plastic liner, it remains under 8309 as long as the outer shell is metal.

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).
