What Do the Different ATA Carnet Colors Mean?
Your ATA Carnet document consists of multiple certificates and are specified by color. The front green cover of the official document shows holder and country information (note: U.S. ATA Carnets have a protective outer folder). The yellow certificates of the document are considered the control documents and remain with the Carnet to be removed by customs. They are used for the registration of goods that will return to the USA. Blue and White Certificates are used by foreign customs. A detailed set of instructions can be found on the inside of the ATA Carnet cover.
