Passenger Name Record rules require mandatory pre-departure PNR transfer to customs systems and strict privacy safeguards. These regulations require aircraft operators and their authorised agents to register and transmit prescribed Passenger Name Record information to the National Customs Targeting Centre-Passenger by a specified push method and message format prior to departure or at wheels-off; they mandate secure processing, prohibit certain sensitive data processing, set a maximum retention period with depersonalisation thereafter, allow case-by-case sharing with law enforcement subject to safeguards, require annual independent audits, and provide for administrative penalties for non-compliance.
