4113.90 - Other:

HTS category 4113.90 encompasses leather derived from animals other than sheep, lambs, goats, kids, swine, or reptiles, which has undergone further preparation after tanning or crusting. This includes, but is not limited to, parchment-dressed leather. The defining characteristic is the absence of wool or hair on the hide, and the material may be split. This broad category serves as a residual for prepared leathers from various animal sources not specifically enumerated in sibling headings.

Unlike sibling categories such as 4113.10 (of goats or kids), 4113.20.00.00 (of swine), and 4113.30 (of reptiles), HTS 4113.90 captures prepared leathers from a diverse range of other animal skins. For example, if a leather is prepared from an animal not listed in these specific headings, and it meets the criteria of being further prepared after tanning or crusting, it would fall under this "other" designation.

Within HTS 4113.90, a further distinction is made between "Not fancy" (4113.90.30.00) and "Fancy" (4113.90.60.00) leathers. This subdivision likely relates to the aesthetic qualities, finishes, or treatments applied to the leather. "Not fancy" leathers generally refer to standard, unembellished preparations, while "fancy" leathers would encompass those with decorative embossing, printing, special finishes, or other ornamental features that enhance their aesthetic appeal beyond basic preparation.
