Re-Entry Permits

Any Montana origin horse leaving the state and returning within 30 days may obtain a 30 day import permit before leaving Montana. 

  • Re-entry permits are only valid for horses leaving the state to participate in events or exhibitions, they are not valid for horses that are being sold, changing ownership or breeding.
  • If the horse does not return to Montana before their Certificate of Veterinary Inspection expires (30 days from the date of inspection), then a new CVI and Import Permit will be required.
  • All testing requirements remain the same

As of April 1st, 2016 horses traveling on electronic Certificates of Veterinary Inspection (eCVI's) will not be required to obtain a re-entry permit

  • The horse(s) must meet all of the above requirements
  • The destination address on the eCVI must be the Montana address the horse is returning to OR
