The ADTP will be administered by the states with federal support. The new rules also apply to movements to and from a Tribal area. In those cases, the Tribal authorities are involved in the system. Background The horse industry has been dramatically affected by serious disease outbreaks in the last ten years, which have halted or restricted the movement of horses and the commerce surrounding the horses.

This new rule is based on the previous National Animal Identification System (NAIS), which was the original voluntary system proposed by USDA to deal with disease outbreaks and traceability.
