Stoppers, corks, of base metal.
Classification of cork stoppers (metal) under HS 8309.10
Metal cork stoppers, commonly known as crown corks or bottle caps, are classified under HS code 8309.10. This classification is situated in Chapter 83, which covers miscellaneous articles of base metal. Heading 8309 includes 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 specifically identifies "crown corks." Despite the name "cork" being used in the trade description, these items are made of base metal (usually steel or aluminum) and often feature a small plastic or cork liner inside to ensure a vacuum seal. The classification is driven by the material of the outer shell (base metal) and its function as a sealing device for containers. These are ubiquitous in the beverage industry for sealing glass bottles of soda, beer, and mineral water.

Codes often confused with 8309.10
Common mistake. The most common misclassification is with HS code 4503.10, which is for stoppers made of natural cork. Users often search for "cork" and select the first material-based result without realizing that "crown cork" is a metal product. Additionally, plastic screw caps are sometimes confused with this code, but those belong in 3923.50. If the stopper is a decorative wine stopper made of metal, it might be classified under 8309.90 or as a household article in 7323, depending on its design.

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).
