HS code 4503.10 is the 6-digit subheading for cork, corks and stoppers, of natural cork. It is used for natural wine corks, champagne corks, stopper corks for spirits, tapered cork stoppers and agglomerated cork stoppers (with natural cork discs).
What HS 4503.10 covers
This HS code specifically covers corks and stoppers made of natural cork, primarily used for sealing bottles, particularly in the wine and spirits industry. These are finished products, ready for use, and represent a significant segment of the global cork market. The international trade in natural cork stoppers is heavily influenced by the beverage industry's demand, with major wine-producing and consuming nations being key importers. Exporters are predominantly countries with robust cork processing industries, leveraging their access to raw cork. Key aspects include the various grades and sizes of stoppers, the importance of cork's sealing properties, and the ongoing competition with synthetic alternatives, though natural cork remains preferred for premium wines due to its breathability and traditional appeal.

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).
