What Happens at Customs When Your Pet Arrives Internationally

The moment your pet lands is when all the preparation either pays off or falls apart. Understanding the customs arrival process before you travel helps you know what to expect and what to have ready.

Who Inspects Your Pet at Customs

Depending on the country, your pet is inspected by one or more of the following:

  • Agricultural or veterinary officers from the national authority (USDA APHIS, Australian DAFF, APHA in the UK, etc.) – these are the key officials for import clearance
  • Customs officers – check for the import permit and validate documentation against the manifest
  • Quarantine station staff – if a quarantine period applies, these officials take charge of your pet

In most countries, the veterinary officer’s clearance is what matters most. If the paperwork is correct and the animal passes a physical health check, clearance is usually quick.

What Officials Check

The veterinary officer will typically check:

  • Microchip (scanned against the documents)
  • Health certificate (within the valid date window, correctly signed and endorsed)
  • Vaccination records (rabies, core vaccines, any specific destination requirements)
  • Titre test result (for countries that require it)
  • Import permit (where applicable)
  • Parasite treatments (tapeworm, flea/tick treatments recorded and within the required window)
  • Physical condition of the animal (healthy, not showing signs of disease)
  • Crate compliance (IATA standards, labelling)

They are checking that every item on the import requirement list is present and valid. A thorough document preparation process should mean there are no surprises here.

What Can Go Wrong

  • Expired health certificate: The most common problem. Health certificates have a narrow validity window (typically ten days from issue date). If your flight is delayed and you miss the window, you may need a new certificate.
  • Missing endorsement: Some countries require a government stamp or endorsement on the vet’s certificate. If the private vet signed it but the government endorsement is missing, the certificate is invalid.
  • Wrong microchip number: The number on the documents must exactly match the chip in the animal. Transcription errors cause significant problems.
  • Titre test not meeting the required level: If the test passed but the level recorded is borderline, officers may question it.
  • Arriving at the wrong port of entry: Some countries (Australia is a notable example) only accept pets at specific airports. Check this carefully.

If Something Goes Wrong

If an officer finds a problem with your documentation, stay calm. Ask clearly what the specific issue is and whether it can be resolved on the spot. Some documentation issues can be corrected in real time. Others – like an expired certificate – cannot be and may result in your pet being held at a quarantine station while the issue is resolved.

Having a pet transport specialist’s emergency contact number is useful in these situations. A good specialist has dealt with customs problems before and can often help navigate the resolution process remotely.

Frequently Asked Questions

Have all documents in a single folder: health certificate, import permit (where required), vaccination records, titre test results (if applicable), microchip documentation, and parasite treatment records. If your country required a government endorsement on the health certificate, ensure that endorsement is present and legible.

Yes. Pets can be refused entry if documentation is missing, expired, or incorrect. The most common reasons are an expired health certificate, missing government endorsement, microchip number mismatch, or absence of a required import permit. Refused pets are typically held at the airport quarantine facility at the owner’s cost while the issue is resolved, or returned to the country of origin.

With all documentation correct, customs clearance for a pet at most airports takes between thirty minutes and two hours. Countries with strict biosecurity regimes (Australia, New Zealand, Japan) have more thorough processes that can take longer. If your pet is arriving as cargo and you are arriving as a passenger on the same flight, allow time for the cargo to be processed before attempting to collect.
