NMFS shall monitor the importation of fish or fish products regulated under this subpart into the United States. If NMFS determines that the diversity of handling practices at certain ports at which fish or fish products regulated under this subpart are being imported into the United States allows for circumvention of the consignment document requirement, NMFS may undertake a rulemaking to designate, after consultation with the CBP, those ports at which fish or fish products regulated under this subpart from any ocean area may be imported into the United States.
