HS code for Wine corks: 4503.10

Cork, corks and stoppers, of natural cork.

Classification of wine corks under HS 4503.10

Wine corks are classified under HS code 4503.10 because they are articles of natural cork. Chapter 45 of the Harmonized System is dedicated to cork and articles of cork. Within this chapter, heading 4503 specifically covers articles of natural cork. This is a critical distinction, as it separates products made from solid, natural cork bark from those made from agglomerated cork, which are classified under heading 4504. Natural cork is harvested from the Quercus suber tree and is valued for its elasticity and near-impermeability. Subheading 4503.10 is the specific international code for corks and stoppers of natural cork. This includes cylindrical corks used for still wines and the natural components of champagne corks. The classification remains the same regardless of whether the cork has been washed, bleached, or coated with paraffin or silicone to aid in the bottling process. According to the General Rules of Interpretation (GRI 1), classification is determined by the terms of the headings and any relative section or chapter notes. Since 4503 explicitly mentions articles of natural cork and 4503.10 specifies corks and stoppers, this code is the most specific and legally correct classification for natural wine stoppers. Importers must ensure that the cork is indeed natural; if the stopper is composed of granulated cork bits glued together, it must be moved to 4504.10.

Codes often confused with 4503.10

Common mistake. Wine corks are frequently confused with HS code 4504.10, which covers agglomerated cork stoppers. Agglomerated cork is made from cork granules bound together with resin or other adhesives. Another common error is 3923.50, which covers plastic stoppers that mimic the appearance of cork but are made of polymers. Using the wrong code can lead to duty discrepancies.

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).
