Species listed under CITES Appendix I or II require export permits from the country of origin and, for Appendix I species, a US import permit from the US Fish & Wildlife Service. Common furskin trade species such as chinchilla are CITES-listed, while others like mink are not. Importers must verify the CITES status of each species before shipment, as violations carry significant civil and criminal penalties.

When a furskin coat and matching furskin hat are imported as a set, the coat and accessories fall under this heading while the hat is classified separately under the furskin headgear provision. Sets are not automatically classified as a unit under a single heading; each component must be assessed individually unless GRI 3 set rules apply, which generally require the components to be put up for retail sale together and classifiable under a single heading.
