In March 2013, three endangered commercially valuable sharks, the hammerheads, the oceanic whitetip, and porbeagle were added to Appendix II of CITES, bringing shark fishing and commerce of these species under licensing and regulation. On 30 January 2018, NOAA Fisheries published a final rule to list the oceanic whitetip shark as a threatened species under the United States Endangered Species Act (ESA) (83 FR 4153).
