ATP (formally, the Agreement on the International Carriage of Perishable Foodstuffs and on the Special Equipment to be used for such Carriage (ATP)) is a 1970 United Nations treaty that establishes standards for the international transport of perishable food between the states that ratify the treaty. It has been updated through amendment a number of times and as of 2016 has 50 state parties, most of which are in Europe or Central Asia. It is open to ratification by states that are members of the United Nations Economic Commission for Europe (UNECE) and states that otherwise participate in UNECE activities. "ATP" is derived from the French name of the treaty: Accord relatif aux transports internationaux de denrées périssables et aux engins spéciaux à utiliser pour ces transports.
