4103.30.10.00 - Not pretanned

HTS code 4103.30.10.00 specifically classifies raw hides and skins of swine that have undergone initial preservation treatments but have not yet been tanned. These preservation methods may include salting, drying, liming, or pickling, and the hides can be dehaired or split. The key characteristic of this classification is the absence of any tanning process, which signifies that the material is still in a raw or semi-processed state and has not yet achieved the stability and durability of leather.

This specific subheading is distinguished from its sibling, 4103.30.20.00, which covers "Other" raw swine hides and skins. While both fall under the broader category of swine hides and skins that are not tanned, 4103.30.10.00 is intended for those undergoing specific preservation treatments as detailed above. The "Other" category would encompass any remaining untanned swine hides and skins that do not fit the more precise description of 4103.30.10.00, potentially including those preserved by less common methods or those that have undergone minimal processing beyond initial flaying.

As a leaf node in the HTS structure, 4103.30.10.00 does not have further subcategories. Therefore, classification at this level depends on a thorough examination of whether the imported raw swine hides and skins have been subjected to preservation techniques such as salting, drying, liming, or pickling, and crucially, have not undergone any tanning, parchment dressing, or further preparation that would advance them towards finished leather. This ensures accurate reporting and appropriate duty assessment for these initial stages of animal hide processing.
