CITES (the Convention on International Trade in Endangered Species) restricts trade in feathers and skins from listed species. Importers must present valid CITES permits and may also need a US Fish & Wildlife Service import declaration or permit, depending on the species and the type of processing applied.

This heading covers bird skins and parts that still bear their feathers or down in a processed state, and loose feather articles not classified elsewhere. Finished stuffed pillows, duvets, or down-filled garments are classified under their respective textile or bedding headings, not here, because the feathers serve as a filling rather than being the primary article.
