4107.92.50.00 - Upholstery leather

This HTS classification covers grain splits of leather from bovine or equine animals, further prepared after tanning or crusting, and which are not suitable for use as upholstery leather, upper leather, or sole leather. These splits represent the inner layer of a hide after the grain layer has been removed, resulting in a less smooth and often more fibrous surface. While they have undergone post-tanning processes, their inherent characteristics or intended end-use prevent them from being classified under more specific categories at this level.

Distinguishing this category from its sibling, 4107.92.60, is crucial. The sibling category specifically enumerates "Upper leather; sole leather." Therefore, this current classification, 4107.92.50.00, encompasses all other grain splits of bovine or equine leather that do not meet the specific criteria for upper or sole leather. It essentially serves as a residual category for such leather splits that possess a split grain but are not designated for footwear or garment uppers.

As this is a leaf node, there are no further subcategories within this specific HTS code. Classification at this level signifies that the goods meet the general criteria for prepared bovine or equine leather, are grain splits, and do not fall into the explicitly defined sibling categories. Therefore, detailed examination of the physical characteristics and intended application will be paramount for accurate classification within this residual grouping.
