HS code for Bottle caps: 8309.90
Stoppers, caps and lids, of base metal.
Classification of bottle caps under HS 8309.90
Bottle caps made of base metal are classified under HS code 8309.90. This classification is found in Chapter 83, which covers miscellaneous articles of base metal. Heading 8309 is dedicated to packaging accessories, including stoppers, caps, lids, and seals. The nomenclature distinguishes between crown corks (the standard crimped caps for glass bottles) and all other types of metal closures. Crown corks are specifically assigned to 8309.10, while all other metal caps, such as aluminum screw caps, lug caps for jars, and flip-top metal lids, fall under the residual category 8309.90. The classification is determined by the material (base metal) and the function (sealing a container). Even if the cap includes a plastic or cork liner to ensure an airtight seal, it remains classified as a metal cap under this heading as long as the metal provides the essential character of the closure.

Codes often confused with 8309.90
Common mistake. The most common misclassification for bottle caps is confusing metal caps with plastic ones. Plastic caps are classified under 3923.50. Another error involves crown corks, which must be classified under 8309.10 rather than 8309.90. Additionally, if a cap is made of precious metal, it would be excluded from Chapter 83 and classified in Chapter 71. Importers must also distinguish between simple caps and complex dispensing pumps, which might fall under 8424.

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).
