Yes. Shark fin imports are subject to US domestic law restrictions and may require documentation demonstrating that fins were not obtained through finning. Importers should verify compliance with the Shark Conservation Act and any applicable CITES listings for the species involved before shipment.

Subheadings for whole or in pieces (e.g., 160411–160419) cover fish that retains recognizable muscle structure, including fillets and chunks. Heading 160420 captures minced fish, pastes, and other forms where the muscle structure has been broken down. The physical form at the time of importation determines which applies.
