4113.30 - Of reptiles:

This HTS category, 4113.30, specifically covers leather that has undergone further preparation after tanning or crusting, originating from reptiles. This includes materials such as alligator, crocodile, snake, and lizard skins, provided they are processed to a leathery state and do not retain their original wool or hair. These leathers, whether split or unsplit, are distinct from raw hides and skins or those classified under heading 4114, which deals with chamois and patent, metallized, or superficially colored leathers.

The primary distinction of this category from its siblings lies in the source animal. While 4113.10 pertains to goat or kid leather and 4113.20.00.00 covers swine leather, 4113.30 is exclusively for leathers derived from reptiles. The broader category of "Other" at 4113.90 would encompass leathers from any other animal not specifically listed in the preceding subheadings.

Within this classification of reptile leather, further distinctions are made based on the finish or aesthetic treatment. The subcategories of 4113.30.30.00 ("Not fancy") and 4113.30.60.00 ("Fancy") delineate between reptile leathers that have received standard processing versus those that have undergone special decorative finishes, embossing, printing, or other treatments to enhance their appearance or texture for higher-value applications.
