4103.30 - Of swine:

This HTS category, 4103.30, specifically covers raw hides and skins of swine. These are unfleshed animal skins that have undergone preservation treatments such as salting, drying, liming, or pickling, but have not yet been tanned, parchment-dressed, or further prepared into leather. This classification includes swine hides and skins that have been dehaired or split, as long as they remain in their raw state and are not processed beyond these preliminary steps.

It is crucial to distinguish this category from its siblings. While 4103.20 pertains to raw hides and skins of reptiles, and 4103.90 encompasses all other types of raw hides and skins not otherwise specified, 4103.30 is exclusively for those originating from swine. This precise differentiation ensures accurate tariff application based on the animal source of the raw material.

The subcategories under 4103.30 further refine the classification based on the extent of prior processing. The distinction between "Not pretanned" (4103.30.10.00) and "Other" (4103.30.20.00) is vital. "Not pretanned" items are those that have received basic preservation but have not undergone any pretanning processes. The "Other" category would encompass swine hides and skins that have been subjected to some form of pretanning treatment, a step that initiates the process towards leather but does not result in fully tanned leather.
