Product classification
HS code for Wet-blue lambskin: 4105.10
Tanned or crust skins of sheep or lambs, without wool on, whether or not split, but not further prepared, in the wet state (including wet-blue).
Classification of wet-blue lambskin under HS 4105.10
Wet-blue lambskin is classified under HS code 4105.10 because it represents sheep or lamb skins that have undergone the initial tanning process but have not yet been dried, dyed, or finished. The term "wet-blue" specifically refers to skins that have been chrome-tanned, a process that utilizes chromium salts to stabilize the collagen fibers of the skin, resulting in a characteristic pale blue color and a moist state. According to the General Rules of Interpretation (GRI) and the specific notes for Chapter 41, this classification is reserved for skins where the wool has been completely removed. The product is considered "in the wet state," which includes both wet-blue and wet-white (aldehyde-tanned) skins. This stage is a critical point in the leather supply chain, as it allows the skins to be preserved for international transport before they are further processed into finished leather for garments or accessories.

Codes often confused with 4105.10
Common mistake. Wet-blue lambskin is frequently confused with raw skins under HS code 4102. However, 4102 is strictly for skins that have not yet undergone the tanning process. Another common error is misclassifying these as "crust" leather under HS code 4105.30; crust leather refers to skins that have been tanned and dried but not finished. Furthermore, if the lambskin has been further prepared (dyed, fat-liquored, or finished), it must be classified under HS code 4112.00. Importers must also ensure the wool is entirely removed, as skins with wool on are classified under 4102.10.

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).
