Moving livestock in Montana

Montana's trigger is a county line, not only the state line, and it is the thing haulers from elsewhere most reliably do not expect. Change of ownership, sale at a livestock auction and slaughter each trigger one as well, and the change-of-ownership inspection is named as the seller's responsibility.

Do not read that as every trip needing an inspector. Montana issues several permits that stand in place of repeated inspections — a permanent permit for a saddle, work or show horse, one for a rodeo producer's bull, a grazing permit into an adjoining county, and consignment and transportation permits that move the inspection to the destination. Which one fits is the inspector's call and it is one phone call.

Brands Enforcement: (406) 444-2045, brands@mt.gov.

Montana is divided into livestock districts, each covering a block of counties with a district investigator and local inspectors. You arrange an inspection through the district that covers where the animals are, not where they are going.

This is the constraint that undoes a plan to load at four in the morning and be over the line by breakfast. It is a reason to ring the day before rather than the hour before.

The owner of a saddle, work or show horse can apply for a permanent transportation permit covering movement both inside Montana and out of it, until the horse changes hands. It goes void the moment ownership changes, and it has to be with the horse in transit.

Montana says it recognises equivalent permanent permits issued elsewhere for a horse coming in. What no page settles is the return leg — whether a horse that arrived on another state's lifetime permit is covered when it later leaves Montana. Ask Brands Enforcement rather than assuming it is.

Same shape as the horse permit: valid for movement inside and outside Montana until there is a change of ownership, carried with the bull, and void the moment the animal is sold.

It covers moving branded livestock onto land the owner owns or controls in an adjoining county, and back again, without an inspection each way. It runs for a set part of a twelve-month period and any movement outside that is inspected; one permit per owner.

This is an in-state instrument. It is not the thing that gets a herd across the line into Idaho for the summer — that is a different permit, issued by Idaho.

Both let livestock cross a county line without an inspection first, on the condition that the inspection happens at the destination.

The Department warns that an inspector may not be available at every slaughterhouse or shipping point, and to get the inspection before you travel if you are unsure. Its own page is also inconsistent about which of these permits can be ordered online, so ask rather than assume the form exists.

A permit is required to take either out of a county or out of the state, and the animals themselves are not inspected.

Worth knowing before you rely on that for bison: the Department's page says bison are permitted rather than inspected, while the statutory definition of livestock for brand purposes names domestic bison. No official page reconciles the two. Ring Brands Enforcement before treating a bison load as permit-only.

Included because it comes up on mixed loads. Nothing on the brand side applies to hogs. The animal health requirements for swine coming into Montana are separate and do apply.

Ownership is proved by a bill of sale or by the most recent brand inspection certificate. A bill of sale has to be signed by the seller and describe the livestock adequately — a scribbled note with a head count is not it.

Livestock may not be removed from Montana to somewhere outside it unless they have been inspected and a certificate issued for that removal. The exceptions are narrow: stock passing through in interstate commerce without leaving the carrier's custody, a market release certificate, and the permanent horse permit above.

Montana makes it a felony, not a fine, for a person other than the owner or the owner's agent to remove livestock from the state without the owner's consent and without the inspection the law requires. There is an exception for emergency veterinary treatment.

The practical version: if the shipper has not arranged the inspection, that is a reason to stay parked.

The application has to reach the Department at least 60 days before the sale. You also arrange with the district livestock investigator to have a brand inspector on site.

That lead time is longer than most people expect and it is the reason to read this before setting a sale date rather than after.

The Department states that this also covers Montana livestock returning from an out-of-state show. Coming home is an entry.

The certificate is written by an accredited veterinarian before the move, which makes it the item most likely to delay a load booked at short notice.

Montana asks for a certificate issued within a window before entry. Idaho counts forwards from the day the certificate was written. Those are two different tests, and the veterinarian writing it needs to know which state's clock applies.

Montana also shortens the window for cattle and horses from states with an active disease finding, which is a reason to check the import page rather than working from the last load.

A handwritten paper certificate needs an import permit. An electronic one does not. Dairy cattle need one either way, whatever form the certificate takes.

What the permit costs, how long it lasts and whose formal job it is to obtain it are not stated on any page that could be cited here. The permit line answers all three: (406) 444-2976.

Montana requires official identification on sexually intact cattle, listed on the certificate itself, with a few narrow exceptions turning on age, on a feeding-only purpose, and on moving directly to an approved tagging site. Dairy cattle get no exception at all.

Which animals in a particular pen fall inside the exceptions is a question for the veterinarian writing the certificate, working from the Department's list.

A negative equine infectious anemia test, dated within the window Montana publishes, with a nursing-foal exception.

Montana accepts a description of the horse — age, colour, sex, breed — or a microchip number as its official identification on the certificate. Horses are not part of the cattle eartag rule, and nothing requires a horse to be microchipped to move between these three states.

Montana requires official identification listed on the certificate for sexually intact sheep, for older sheep of either sex and for exhibition sheep, plus a statement about scrapie on the certificate itself. Rams carry a testing requirement.

Montana also names species it will not admit at all. If the load includes anything unusual, that list is worth reading before it is loaded rather than after.

Not on leaving the state — on leaving the area. Testing and identification apply to animals moving out of it, and in named counties there is a vaccination requirement for females that reaches seasonally grazed cattle as well as resident ones.

This is the Montana rule out-of-state haulers most reliably do not expect, because it applies to a move that never leaves Montana. Idaho then applies a testing requirement of its own to cattle arriving from a surveillance area, so a Montana-to-Idaho move can carry both.

Montana conditions or stops entry from particular states by animal health order, without a rule change and without notice. Orders in force when this page was checked covered New World screwworm findings and vesicular stomatitis, and there was a testing condition on dairy cattle from certain states.

Do not plan a load on what this page says about them. Open the import page the week you are moving.

Montana issued animal health orders in June 2026 following a New World screwworm detection, conditioning entry from restricted states on a permit, a treatment before entry, an inspection and official identification.

It is dated here on purpose. An emergency order can be tightened, widened or lifted at any time, so read the order itself rather than this summary of it.

The certificate of inspection, market consignment permit, transportation permit or market release certificate has to be in the possession of the person in charge of the livestock and shown on request to a sheriff, a deputy, a highway patrol officer or a stock inspector.

Montana accepts a digital copy for travel and transportation purposes, which is worth knowing before somebody drives back for a piece of paper.

Where a single permit or health certificate covers animals moving in more than one vehicle, each driver has to be holding a copy. This catches loads split at the last minute more often than anything else on this page.

If animals are not in compliance when they arrive, the Department can refuse to let them unload, and missing documents can bring a citation. That is the real cost of a certificate somebody meant to sort out on the way.

Montana's export guidance points you at a brand inspector and at the receiving state's own requirements. In practice Montana controls the brand paperwork on the way out and the other state controls the certificate, the testing and the entry permit.

Absence of a published Montana outbound certificate requirement is not proof there is none for every scenario. Ask Animal Health if the move is unusual.
