Product classification
HS code for Metal stoppers: 8309.10
Stoppers, corks, of base metal.
Classification of metal stoppers under HS 8309.10
Metal stoppers, specifically crown corks and similar sealing devices, are classified under HS code 8309.10. This classification is governed by the Section XV notes and the specific descriptions in Chapter 83, which covers miscellaneous articles of base metal. Heading 8309 is dedicated to stoppers, caps, lids, capsules for bottles, threaded bungs, bung covers, seals, and other packing accessories of base metal. The subheading 8309.10 is specifically reserved for crown corks, which are the standard metal caps used for sealing glass bottles, typically containing carbonated beverages. These items are characterized by their fluted edges and a liner (often plastic or cork) that ensures an airtight seal. The classification remains in 8309.10 even if the metal is painted, printed, or lacquered, as long as the primary material is a base metal like steel or tinplate. The manufacturing process involves stamping and forming the metal into a shape that can be crimped onto a bottle neck.

Codes often confused with 8309.10
Common mistake. A common misclassification occurs with HS code 8309.90, which is a residual category for other stoppers and caps that are not crown corks, such as screw caps or aluminum foil seals. Confusion also arises with HS code 7326.90, which is a general code for other articles of iron or steel. However, because 8309 is more specific to the function of sealing and packing, it takes precedence over 7326 according to GRI 3(a). Furthermore, if the stopper is made entirely of natural cork, it must be classified under 4503.

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).
