4103.90.11 - Not pretanned

This HTS category, 4103.90.11, specifically covers raw hides and skins, other than those of bovine or equine animals, which have undergone initial preservation treatments but have not yet been tanned or further prepared into leather. This includes materials that have been salted, dried, limed, or pickled, and may or may not have been dehaired or split. The key defining characteristic is that the material remains in its raw state, not having undergone the chemical or physical processes that transform a hide or skin into leather.

Within the broader classification of "Other raw hides and skins," this specific subheading distinguishes itself by focusing on the "Not pretanned" condition. It occupies a space distinct from any potential sibling categories that might address more processed or specific types of raw hides and skins. The emphasis here is on the preliminary stages of preservation before the material is ready for tanning.

This category further breaks down into more specific types of animal hides and skins. Subheadings 4103.90.11.30, 4103.90.11.40, and 4103.90.11.90 are established to differentiate based on the animal origin of the raw hide or skin, namely deer, goats or kids, and other unspecified animals respectively. This granular classification allows for precise tracking and tariff application based on the source material.
