Interstate movement is where private livestock sales go sideways — not because the rules are harsh, but because sellers find out about them the morning of the haul. Here is the whole picture, in the order you need it.
The short version
For nearly any animal crossing a state line, plan on a Certificate of Veterinary Inspection from an accredited vet, official individual identification, and whatever testing the destination state requires for that species. Brand inspection applies in some western states. The destination state's rules govern, they change, and your vet or state animal health office is the only current source.
The rule that decides everything: destination state governs
Whatever your own state allows, the animals have to be legal to enter where they are going. That means you check the destination state's import requirements, not just your own.
Requirements differ by species, by age, by sex, by intended use — breeding stock is usually regulated more tightly than animals going straight to slaughter — and they change with disease outbreaks. There is no evergreen checklist anyone can honestly publish.
Two reliable sources: an accredited veterinarian in your area, who writes these certificates weekly, and the destination state's animal health office or state veterinarian. Call before you advertise a delivery date.
Certificate of Veterinary Inspection (CVI)
An accredited vet examines the animals, lists their identification, and certifies they appeared healthy. Interstate movement almost always requires one.
Typical validity is about 30 days, and some states are shorter. Time the inspection so the certificate is still valid on hauling day, not the week before.
Schedule ahead. Vet calendars in spring and fall fill up, and a rushed farm call costs more.
Official identification
Most interstate movement requires official individual ID recorded on the certificate. For cattle that commonly means an official ear tag; electronic identification requirements have been expanding for certain classes of cattle and bison.
Other species have their own systems — scrapie tags for sheep and goats, premises or official ID for swine, and description or microchip records for horses.
Tag before the vet comes. Tagging during the appointment turns a one-hour visit into three.
Testing that comes up most often
Horses: a current negative Coggins test for equine infectious anemia is the standard interstate requirement.
Breeding cattle: brucellosis and tuberculosis testing requirements depend on age, sex, class and destination state.
Sheep and goats: scrapie identification is the common baseline, with additional testing for some breeding stock.
Swine: pseudorabies and brucellosis testing rules vary by state and by whether the animals are breeding stock.
Poultry: many states require National Poultry Improvement Plan status or testing for birds entering the state.
Brand inspection
A number of western states require brand inspection before cattle and horses are sold or moved, and the boundary can be a defined area inside a state rather than the whole state.
It is a separate process from the health certificate, with its own inspector and its own timing. If your state or the destination state has brand law, build it into the schedule and tell the buyer who is handling it.
Permits, ICVI numbers and entry permits
Some states require an entry permit number written on the certificate before the animals move. Your veterinarian normally obtains it, but only if they know the destination — so tell them exactly where the animals are going.
Keep copies. The hauler needs one in the truck, the buyer needs one, and you should keep one with your own records.
Sorting it out with the buyer before money changes hands
Agree in writing on four things: who arranges the vet, who pays for papers and testing, who hauls, and what happens if a test comes back positive or the certificate cannot be issued.
Build the timeline backwards from the haul date. Test results take days, not hours, and a brucellosis or Coggins result cannot be rushed at the last minute.

Common questions
- What is a CVI?
- A Certificate of Veterinary Inspection — often just called a health certificate — is a document from an accredited veterinarian saying the animals were examined and appeared free of infectious disease, with their identification listed. Most interstate livestock movement requires one.
- How long is a health certificate good for?
- Commonly 30 days from the date of inspection, but the destination state sets the window and some shorten it. Confirm before you schedule the haul, because an expired certificate stops the load.
- Do horses need a Coggins test to cross state lines?
- A current negative Coggins (EIA) test is standard for interstate horse movement, usually within the last 12 months, and many states and events require it. Check the destination state's current requirement.
- Who pays for the health papers, buyer or seller?
- There is no universal rule, so agree before the deal is closed. The common arrangement is that the seller arranges and pays for the CVI and testing, and the buyer pays the haul — but say it out loud either way.
- Do I need paperwork for a sale inside my own state?
- Usually far less. Many states do not require a CVI for a private in-state sale, though brand inspection or species-specific rules can still apply. The paperwork requirements ramp up the moment the animals cross a line.
- What happens if I haul without the right papers?
- You can be turned back, fined, or have the animals held. It is also the fastest way to lose a buyer — nobody wants a load that cannot legally arrive.
