HS code for Agglomerated cork blocks: 4504.10
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 agglomerated cork blocks under HS 4504.10
HS 450410 specifically covers blocks, plates, sheets, strips, tiles, and solid cylinders (including discs) made from agglomerated cork. The term "agglomerated cork" is crucial here, indicating that the cork material has been processed by binding smaller cork particles together, typically with an adhesive. This distinguishes it from natural cork in its raw or minimally processed forms. The code also specifies that the presence or absence of a binding substance does not alter the classification, acknowledging variations in manufacturing processes for agglomerated cork products. This classification reflects the manufactured nature and common forms of these cork products.

Codes often confused with 4504.10
Common mistake. Other HS codes often confused with 450410 include: HS 4501 (Natural cork, raw or simply prepared; waste cork; crushed, granulated or ground cork). This code covers natural cork in its unprocessed or minimally processed forms, such as raw bark or granulated cork. Agglomerated cork, which involves binding these particles, is a manufactured product and is specifically classified under 4504. HS 4503 (Articles of natural cork). This code is for finished articles made directly from natural cork. Agglomerated cork products are distinct because they are made from re-formed cork particles, not solid natural cork. HS 450490 (Other articles of agglomerated cork). This is a residual category for other articles made of agglomerated cork that are not specifically enumerated in 450410. Blocks, plates, sheets, strips, tiles, and solid cylinders are explicitly covered by 450410 and should not be classified under the "other" category.
Top exporters and importers of HS 450410 (the code used for agglomerated cork blocks), 2025
In 2025, the largest exporter of HS 450410 (the code used for agglomerated cork blocks) in UN Comtrade data was Portugal, with 62% of world exports; the largest importer in UN Comtrade data was France, with 19% of world imports.

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).
