Cork, blocks, plates, sheets and strip, tiles of any shape, solid cylinders (including discs), of agglomerated cork (with or without a binding substance).
Classification of cork sheets under HS 4504.10
Cork sheets made from agglomerated cork are classified under HS code 4504.10. This code is part of Chapter 45, which covers cork and articles of cork. Heading 4504 is specifically dedicated to agglomerated cork, which is produced by binding cork granules or dust with a binding substance, often under heat and pressure. Subheading 4504.10 covers primary forms such as blocks, plates, sheets, and strips, as well as tiles of any shape and solid cylinders. The classification is determined by the fact that the material is no longer in its natural state but has been reconstituted. These sheets are widely used for industrial gaskets, bulletin boards, and flooring underlayment. To fall under this code, the product must be in a flat, sheet-like form and consist of agglomerated cork. If the sheets are further worked into specific shapes or finished articles like gaskets, they may remain here or move to 4504.90 depending on the degree of processing.

Codes often confused with 4504.10
Common mistake. The most frequent misclassification occurs with HS code 4503.90, which is for sheets of natural cork. Natural cork sheets are sliced directly from the bark and do not contain binders. Another common error is using 4411 for fiberboard; while similar in appearance, cork-based sheets must stay in Chapter 45. Furthermore, if the cork sheet is backed with adhesive and intended for stationery use, some may confuse it with Chapter 48, but the cork content usually dictates classification in 4504.

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).
