A livestock health certificate, known formally as a Certificate of Veterinary Inspection (CVI), is an official document certifying that the animals listed on it were inspected, found apparently healthy, and meet the movement rules that apply to them. Per APHIS, an interstate CVI may be issued by a USDA-accredited veterinarian or by a Federal, State, or Tribal Animal Health Official, though in practice most owners go through an accredited veterinarian. In plain terms, it is the paperwork most states require before livestock cross a state line. The American Veterinary Medical Association describes a CVI as an official document certifying that the animals identified on it “have been inspected and were found to satisfy the regulations pertaining to their intended movement.” There is no single national CVI standard for what a receiving state demands. Each state sets its own entry requirements, so the rules that matter are almost always the destination state’s, and they change. This guide explains what a CVI covers, when you actually need one, who is responsible for what, and how to get one without last-minute panic before a haul or a sale. A certificate is also only worth as much as your ability to produce it later, so it belongs with the animal’s other health records rather than loose in a folder.
What a certificate of veterinary inspection actually is
A CVI is a legal record that ties a specific set of animals to a specific inspection on a specific date. Per APHIS, it can be issued by a USDA-accredited veterinarian or by a Federal, State, or Tribal Animal Health Official. Penn State Extension describes the same document, the health certificate, as verification that the animal was recently examined and found to have no obvious signs of illness.
The certificate identifies the animals (species, breed, sex, age, and whatever identification their species and class actually requires: individual official ID numbers for some, a group or lot number where a class is allowed to move that way, and neither where the class is exempt), names the origin and destination with addresses, records any required test results or vaccinations, and carries the issuer’s name and, for an accredited veterinarian, clinic and accreditation number. It can be issued on paper or electronically. Because it is a certification and not a receipt, it has to rest on an actual inspection of the animals rather than paperwork alone. (Who may issue it, an accredited veterinarian or an authorized Federal, State, or Tribal Animal Health Official, is a separate question from that inspection.)
One point trips people up constantly: for interstate movement, USDA APHIS is not the agency that issues or endorses your CVI. As APHIS states in its National Veterinary Accreditation Program guidance, individual states provide the certificates, and “APHIS is not involved in certificate issuance or endorsement of certificates used for interstate movements.” APHIS endorsement comes into play for international export, not for hauling cattle from one state to the next. For interstate moves, the destination state’s animal health agency sets the terms.
When you actually need one
The trigger for most CVIs is crossing a state line. The federal framework for interstate movement of cattle, horses, swine, sheep, and goats lives in Title 9 of the Code of Federal Regulations, parts 70 through 89, and most states add their own requirement that livestock entering from out of state carry a CVI. That covers the everyday situations owners run into: selling an animal to a buyer in another state, hauling breeding stock to a farm across the line, taking animals to an out-of-state show, fair, or sale, and bringing new animals home from elsewhere.
Two honest caveats keep this from being a blanket rule. First, some intrastate moves (within a single state) also require a CVI or other documentation, depending on state law and the venue, so a certificate is not purely an interstate thing. Second, there are real exemptions. Animals consigned directly to slaughter, or to an approved market and then to slaughter, commonly move under an owner-shipper statement instead of a CVI. Several states spell this out: California and Florida, for example, exempt cattle moving directly to slaughter with an owner-shipper statement from the CVI requirement. So do not assume you are covered, and do not assume you are exempt. Confirm the specific movement with the destination state.

Who does what: owner, veterinarian, and state
Regulatory paperwork goes wrong when nobody is clear on who owns which duty. For a CVI, the work splits three ways.
The owner or shipper is responsible for arranging the inspection in time, providing accurate origin and destination information, having the animals identified, and carrying the completed certificate with the shipment. Penn State Extension notes that animal owners typically arrange CVI services. If a test or permit is required, it is on you to schedule it far enough ahead. A CVI is not something you can produce at the loading chute; the testing timelines usually make that impossible.
A CVI rests on a physical inspection of the animals, confirmation of their identity, and whatever tests the destination requires. The person who performs that hands-on inspection is an accredited veterinarian, and usually that same veterinarian is the issuer who completes and signs the certificate. But the issuer and the inspector are not always one and the same: per APHIS an authorized Federal, State, or Tribal Animal Health Official may also issue the document (9 CFR 86.5 lets an APHIS, State, or Tribal representative issue it). An accredited veterinarian is, APHIS is explicit, responsible for becoming familiar with the applicable state and federal movement regulations and inspecting animals accordingly. And for some tests the veterinarian cannot delegate the work: APHIS notes that veterinarians are legally responsible for properly conducting and evaluating tuberculin (TB) tests themselves and cannot hand that off to a technician.
The state, through its state veterinarian’s office, sets the entry requirements and may also require an entry permit issued by the destination state. APHIS advises contacting the state or territorial veterinarian’s office in the state of destination for questions on interstate entry requirements. When origin and destination rules differ, the stricter or destination requirement generally governs what you have to do.
What the veterinarian checks and documents
A CVI inspection is a hands-on look at whether the animals are fit to move and free of obvious signs of communicable disease. The vet examines general condition and behavior, looks for signs of illness or external parasites, confirms that the animals which require official identification are correctly identified against the paperwork, and records the required details. The certificate then documents species, breed, sex, and age, the required identification (individual official ID numbers, or a group or lot number where a class is allowed to move under group identification), origin and destination, any test results and vaccination or treatment records the destination requires, and any import permit number.
None of this replaces a diagnosis or a treatment plan. A clean CVI means the animals looked healthy on inspection day and met the movement rules; it is not a guarantee against incubating disease, and it is not medical advice. Keep your own veterinarian in the loop for anything clinical, and defer treatment and drug decisions to them.
Tests and vaccinations vary by species
This is where “check your destination state” stops being boilerplate and starts saving you a wasted trip. Test and vaccination prerequisites depend on the species, the class of animal, where it originates, and the destination state’s current disease status. A few examples show how far apart the requirements can land.
Cattle and bison. Depending on the class of animal and the origin and destination states, cattle may need a brucellosis test, a tuberculosis test, or both before interstate movement. These programs are federal and coordinated by APHIS under 9 CFR, but exactly which animals must be tested is class-specific (sexually intact adult cattle are treated differently from steers, for instance). Your veterinarian and the destination state veterinarian determine what applies.
Horses. Nearly every state requires a negative test for equine infectious anemia (EIA), usually called a Coggins test, for horses crossing a state line, in addition to a CVI. Penn State Extension and equine associations describe the Coggins as standard for interstate travel; the acceptable window varies by state, commonly within the previous 6 to 12 months. A blood sample must be drawn by a licensed veterinarian and tested at an approved laboratory, so a Coggins is not a same-day item either.
Sheep and goats. The dominant federal requirement here is official identification under the National Scrapie Eradication Program, not a specific vaccination. The scrapie rules are class-based rather than a blanket requirement on every animal: APHIS requires official ID for sheep and goats in interstate commerce that are 18 months of age and over, and for all sexually intact animals under 18 months, while some lower-risk classes are handled differently (for example, wethers under 18 months, or animals moving in recognized slaughter channels under a group or lot identification and an owner or hauler statement). Producers can request free scrapie flock ID tags (APHIS has provided up to 100 tags free to first-time participants) by calling 1-866-USDA-Tag. Some states impose stricter rules than the federal minimum, so confirm what applies to your animals and your destination.
Swine. Pigs generally need individual official identification for interstate movement unless they are kept and moved as a group, in which case a group or lot identification can stand in for individual ID. Pseudorabies requirements under 9 CFR Part 85 can also apply, which is why swine often must originate from qualified pseudorabies-negative herds or a recognized free state. A CVI, typically completed within 30 days, is standard, and the destination state may require additional testing or a permit.

How long a CVI is valid
The commonly cited figure is 30 days from the date of inspection, and for many species and states that is accurate. But it is not a universal constant, and treating it as one is how animals get turned away at a state line or a show gate.
The window can be shorter. A state veterinarian in either the origin or destination state can require a tighter timeframe to manage disease risk, and during an active outbreak some CVIs are honored only for a matter of days. It can also be longer for certain categories. Some states recognize extended-validity certificates, and equine programs in particular offer longer-term options in some states. Because the acceptable window is set by the destination state and by current disease conditions, verify it for your specific move rather than assuming 30 days. If you move the same horse across the same line often, ask your veterinarian whether an extended equine certificate is offered where you travel.
Official identification and the 2024 electronic ID rule
Official identification is central to traceability, but it does not fall the same way on every animal or every CVI. Whether an animal needs its own individual official ID, can instead move under a group or lot identification, or falls outside the individual-identification requirement altogether depends on its species and class. For cattle, the individual-ID requirement targets specific classes, and feeder cattle and cattle moving directly to slaughter are commonly excluded from it, moving instead on backtags or under a group or lot identification. The rules for cattle identification also recently changed. USDA APHIS published a final rule in 2024 requiring official identification eartags for certain classes of cattle and bison to be both visually and electronically readable (RFID) to count as official ID for interstate movement. The rule took effect November 5, 2024.
The classes covered are all sexually intact cattle and bison 18 months of age and over, cattle and bison of any age used for rodeo, shows, exhibitions, and recreational events, and dairy cattle (all female dairy cattle of any age, and all male dairy cattle born after March 11, 2013). There is a grandfather provision: animals already carrying a visual-only official ID tag applied before the effective date do not need to be re-tagged, and that visual tag remains official for the animal’s lifetime. If you are moving covered cattle interstate and tagging fresh animals, plan on electronic ID eartags. Sheep, goats, and swine continue under their own identification programs described above.
How to actually get one
The mechanics are straightforward once you build in enough lead time.
- Identify the destination state’s requirements first. Contact the destination state veterinarian’s office or check its animal health agency website. USDA APHIS also maintains a state and territory animal entry requirements page that points to each state’s rules. Do this before you book anything, because required tests set your timeline.
- Confirm identification for the animals that need it. Make sure each animal that requires official identification carries the correct ID for its species and class, and that any animals moving under a group or lot identification are properly documented. For covered cattle, that means the electronic eartag the 2024 rule requires.
- Schedule the inspection and any tests with an accredited veterinarian. Per APHIS, an interstate CVI may be issued by a USDA-accredited veterinarian or by a Federal, State, or Tribal Animal Health Official; in practice most owners go through an accredited veterinarian. Book far enough ahead that lab tests (a Coggins, a brucellosis or TB test) return before your move date.
- Get any required entry permit. Some states require a permit number issued by the destination state, which your veterinarian usually obtains as part of completing the certificate.
- Travel with the paperwork. Carry the signed CVI (and Coggins or other test records) with the shipment, and keep a copy for your own records.
Keep the paperwork where you can find it
A CVI is only useful if you can produce it. Test results, tag numbers, and inspection dates are exactly the kind of information that ends up scattered across truck consoles, email attachments, and folders in the barn office, and then goes missing the week you need it for a sale or a fair entry.
Storing each animal’s health documents on its own profile is a practical habit, not a legal requirement, and it is where a records platform earns its keep. On Creatures you can keep a CVI, a Coggins result, vaccination dates, and official ID numbers attached to the individual animal, so the paperwork travels with the animal’s history instead of your memory. If you run a herd or a multi-owner operation, keeping these records in one shared place also means the person loading the trailer is not guessing about which animals are current. For how the records tools work, see the Creatures help articles on adding a record and health and medical records, and the walkthrough of the animal records tab. If you already track this in a spreadsheet, importing records brings it over.
The same record-keeping discipline that keeps CVIs findable helps everywhere else on the farm. For the broader system, see the cattle record-keeping guide, and if you are thinking about the business side of moving and selling animals, the small farm tax deductions guide covers how good records support your books.
Frequently asked questions
Is a health certificate the same as a CVI?
Yes. “Health certificate” is the everyday name for a Certificate of Veterinary Inspection. Some people also call it a travel certificate. They refer to the same official document, completed for animal movement by an accredited veterinarian or an authorized Federal, State, or Tribal Animal Health Official.
Do I always need a CVI to move livestock across state lines?
Usually, but not always. Most states require a CVI for livestock entering from out of state, and interstate movement is governed by federal rules in 9 CFR parts 70 to 89. Common exceptions include animals moving directly to slaughter under an owner-shipper statement. Because requirements and exemptions vary by state, confirm your specific move with the destination state veterinarian’s office.
Who has to sign the certificate?
Usually a licensed veterinarian who holds current USDA accreditation. APHIS also allows an interstate CVI to be issued by a Federal, State, or Tribal Animal Health Official, an official capacity that is not the same thing as being your accredited vet. A technician or the owner cannot sign one.
How long is a CVI good for?
Often 30 days from the inspection date, but this is not universal. A state veterinarian can require a shorter window during a disease event, and some categories and states allow longer validity. Verify the window with the destination state before you move.
How much does a CVI cost and how far ahead should I plan?
The fee depends on your veterinarian and on which tests are required, so there is no single national price. Plan well ahead: tests such as a Coggins or a brucellosis or TB test are sent to a laboratory and take time to return, so a CVI cannot be a same-day item when testing is involved.
Where do I find my destination state’s rules?
Contact the destination state veterinarian’s office or check its animal health agency website. USDA APHIS maintains a state and territory animal entry requirements page that links to each state’s requirements.
Do this next on Creatures
Whether you are prepping for a haul, a sale, or a show, the moving parts of a CVI (tests, tag numbers, inspection dates) are easiest to manage when they live with the animal. Creatures is the records, marketplace, and directory layer to keep it all in one place.
Store the certificate on the animal. Keep any applicable CVI and whatever else that animal’s move calls for, test results like a horse’s Coggins, vaccination dates, where they travel with the animal’s history. Add a health record on Creatures. The record sheet opens for any visitor to look around, and a free account saves what you enter. The how-to is in adding a record and health and medical records.
Add your animal. Keeping cattle? Create a free animal profile (swap in your own species) so its records, including any official ID it actually needs, live in one profile. See the animal records tab for what each tab does, and importing records if you are moving over from a spreadsheet.
Manage a herd or farm as a team. If more than one person loads trailers or files paperwork, set up a farm or organization profile so records are shared, not stuck on one phone. Walkthrough: apply records and track activity for a group.
Buying or selling across state lines? Browse cattle listings on the marketplace and search trusted farms and breeders in the Creatures directory. Interstate purchases are exactly when CVI paperwork matters, so line it up before the animal moves.
Watching for the right animal? Set a free listing alert and Creatures will tell you when a match is posted. No account needed to start.
This guide is educational and general. CVI rules are set by each state and by USDA APHIS and they change, so confirm current requirements with your veterinarian and the destination state veterinarian’s office before you move any animal.
