4103.20 - Of reptiles:

This HTS category, 4103.20, specifically encompasses raw hides and skins derived from reptiles. These materials are fresh, or preserved through methods such as salting, drying, liming, or pickling, but have not undergone tanning or further preparation into leather. The classification applies whether the reptile hides and skins are dehaired or split, as long as they remain in a raw or semi-prepared state, excluding those specifically prohibited by Chapter 41 notes.

Distinguishing this category from its siblings, 4103.30 pertains exclusively to raw hides and skins of swine, while 4103.90 serves as a catch-all for other raw hides and skins not specifically enumerated elsewhere within the 4103 heading. Therefore, 4103.20 is solely dedicated to classifying the raw, unworked hides and skins originating from various reptile species.

Within 4103.20, a further subdivision exists to refine the classification based on the stage of preparation. The subcategory 4103.20.10.00 specifically addresses reptile hides and skins that have not been pretanned. An "Other" subcategory would then capture those reptile hides and skins that have undergone pretanning, indicating a transitional stage before full leather processing.
