HS code for Wet-blue kidskin: 4106.21

Tanned or crust hides and skins, of goats or kids, without wool or hair on, whether or not split, but not further prepared, in the wet state (including wet-blue).

Classification of wet-blue kidskin under HS 4106.21

Wet-blue kidskin is classified under HS code 410621. This classification is based on the biological origin of the skin and the specific stage of the tanning process. Chapter 41 covers hides and skins, and heading 4106 is designated for the hides and skins of animals not covered in previous headings (such as bovine, equine, sheep, or swine), specifically including goats and kids. The subheading 410621 refers to skins in the "wet state," specifically "wet-blue," which indicates the skin has undergone chrome tanning but has not yet been dried, dyed, or further finished. This state is characterized by a distinct blue tint from the chromium salts and is a standard intermediate stage in international leather trade.

Codes often confused with 4106.21

Common mistake. Wet-blue kidskin is often confused with 410390, which covers raw hides and skins. However, once the tanning process has begun, the item must move to 4106. Another common error is misclassifying it under 411310, which is for goat or kid leather that has been further prepared (crust or finished) after tanning. Since wet-blue is an unfinished, wet stage, 410621 is the only appropriate code. It should also not be confused with 410622, which covers skins in the dry state (crust).

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).
