Grievance redressal: passengers may approach Customs officers or airport facilitation committee for complaint resolution at arrivals. Grievance redressal for international air passengers relies on the Green Channel for those with nothing to declare while providing accessible complaint mechanisms: courteous Customs conduct, illuminated notices directing passengers to the PRO (Customs), options to lodge complaints with the Commissioner of Customs or the Central Vigilance Commission, and round the clock availability of senior Assistant/Deputy Commissioners to receive grievances.
