Division 7

CBP will consult with the European Commission regarding revision of the required PNR data elements (Attachment A), prior to effecting any such revision, if CBP becomes aware of additional PNR fields that airlines may add to their systems which would significantly enhance CBP's ability to conduct passenger risk assessments or if circumstances indicate that a previously non-required PNR field will be needed to fulfil the limited purposes referred to in paragraph 3 of these Undertakings.
