Reptile skins from species listed under CITES (Convention on International Trade in Endangered Species) require valid CITES export permits from the country of origin and CITES import permits issued by the US Fish and Wildlife Service. The specific permit requirements depend on whether the species is listed on CITES Appendix I or II, so importers should confirm the species' listing status before arranging shipment.

The named subheadings for goat/kid, swine, and reptile take precedence; 410691 (wet state) and 410692 (dry state) capture all remaining hair-off tanned or crust skins not specifically described elsewhere in the heading — for example, deer, kangaroo, or other specialty hides. Classification requires identifying the animal species first, then applying the residual subheading only if no specific provision exists.
