Finished reptile leather remains subject to CITES controls regardless of the degree of processing. Importers must present valid CITES export documentation from the country of origin and, for Appendix I species, a US Fish and Wildlife Service import permit. CBP coordinates with USFWS at the port of entry, and shipments lacking proper permits may be detained or refused.

Ostrich leather, once further prepared after tanning, falls under 411390 (other animals, NESOI) because ostrich is neither a bovine, equine, sheep, lamb, goat, kid, swine, nor reptile. The NESOI subheading captures all finished hair-off leather from species not specifically named in the heading, making it the correct classification for ostrich, kangaroo, deer, and similar specialty leathers.
