Moving Pets from the USA to Thailand: The Complete Import Guide
Moving a dog or cat from the USA to Thailand is achievable — but it requires a specific sequence of US government documentation that most vets and even some pet relocation services do not know well. The bottleneck is not Thailand’s requirements; Thailand’s Department of Livestock Development (DLD) issues import permits straightforwardly. The bottleneck is the US side: USDA-accredited veterinary health certificates endorsed by USDA APHIS (Animal and Plant Health Inspection Service), with timing constraints that leave very little margin for error.
Get the sequence wrong — wrong microchip standard, health certificate issued too early, rabies vaccination outside the valid window — and your pet will be denied boarding in the USA or refused entry in Thailand. This guide walks through every requirement for dogs and cats specifically, in the order they must be completed, with the timing constraints that trip people up.
Note: we already published a companion guide covering moving pets from Europe to Thailand — this guide covers the US-specific documentation pathway, which differs in the USDA endorsement requirement and the airline options available from the USA.
—Thailand’s Status on Rabies and Why It Matters
Thailand is not a rabies-free country. This is the single most important fact in Thailand’s pet import rules. Countries considered “rabies-free” (such as Japan, Singapore, Australia, and some EU countries) are treated differently — Thailand has simplified entry rules for pets arriving from rabies-free countries. The USA is not on this list.
For pets arriving from non-rabies-free countries like the USA, Thailand’s DLD applies its full import protocol: valid Thai import permit, USDA APHIS-endorsed health certificate, current rabies vaccination within the valid window, and ISO-compatible microchip. The good news: if these requirements are met correctly, there is no mandatory quarantine period — your pet goes through a DLD inspection at the airport and is released to you. The inspection is typically 30–60 minutes at the livestock checkpoint inside customs.
—Step-by-Step: The US-to-Thailand Pet Import Process
Step 1: Microchip (ISO 11784/11785 Standard)
Thailand requires a 15-digit ISO 11784/11785-compliant microchip (134.2 kHz) for all imported dogs and cats. This is important for American pet owners because many US vets implant a different chip standard: the 125 kHz (9-digit) chip used by HomeAgain and AVID in the USA. A 125 kHz chip will not be read by Thailand’s ISO scanners.
If your pet already has a US-standard chip, you have two options:
- Have a second ISO-compliant chip implanted (your vet can do this; the old chip stays in place). The ISO chip must be implanted before the rabies vaccination that will appear on the health certificate — otherwise the certificate cannot link the rabies vaccination to the ISO chip number.
- Purchase a universal scanner that reads both chip types and carry it with you — but note that Thai DLD may only scan with their standard equipment, so this is not a reliable workaround.
Recommendation: If your pet does not have an ISO 11784/11785 chip, implant one first, then complete the rabies vaccination, then obtain the health certificate. This sequence is critical.
Step 2: Rabies Vaccination
Thailand requires proof of current rabies vaccination. The timing constraints are:
- Minimum: The rabies vaccination must have been administered at least 21 days before the date of travel into Thailand.
- Maximum: The vaccination must be current — within the manufacturer’s stated validity period (typically 1 year or 3 years depending on the vaccine). Thailand checks the vaccination expiry, not just the date administered.
An annual booster must be given before the previous vaccination expires — a lapsed rabies vaccination means starting the 21-day wait again, which may delay your travel date. Plan backward from your intended travel date to ensure the 21-day minimum is met without cutting it close.
Step 3: Thai DLD Import Permit
Before anything else on the Thai side, you need an import permit from Thailand’s Department of Livestock Development (DLD). This is applied for online through the Thai DLD website and should be submitted at least 30 days before your intended arrival date in Thailand.
The import permit application requires:
- Species and number of animals (dogs and/or cats, how many)
- Your name and Thailand address or contact
- Intended date of arrival
- Port of entry (typically Suvarnabhumi Airport, Bangkok, for US arrivals)
- Name of the USDA-accredited veterinarian who will issue the health certificate (if known at application time)
The DLD issues the permit as a PDF document. Print it and carry it with all other pet travel documents. The permit is granted for a specific arrival window — confirm the validity dates when you receive it.
Step 4: USDA-Accredited Vet Health Certificate
The health certificate must be issued by a USDA-accredited veterinarian (not just any licensed vet — specifically USDA-accredited). Search for USDA-accredited vets in your state using the USDA APHIS veterinary accreditation portal.
Critical timing constraint: the health certificate must be issued no more than 10 days before your travel date. This means the vet appointment must be scheduled in the final 10-day window before departure, not weeks in advance.
The health certificate must include:
- Pet’s name, species, breed, sex, age, colour
- Microchip number (the ISO 11784/11785 chip number)
- Rabies vaccination details (date, vaccine brand, batch number, expiry date)
- General health examination confirming the pet is clinically healthy and free of clinical signs of infectious disease
- Any other vaccinations (DHLPP for dogs, FVRCP for cats — not required by Thailand but strongly recommended)
- Confirmation that the pet is fit to travel
The USDA-accredited vet completes the certificate in a format accepted by USDA APHIS for endorsement. Ask your vet to use the USDA Form VS 7001 (official interstate and international certificate of health examination for small animals) or confirm they are familiar with the Thai DLD requirements and the APHIS endorsement process.
Step 5: USDA APHIS Endorsement
After the health certificate is signed by the USDA-accredited vet, it must be endorsed (countersigned and stamped) by the USDA APHIS Veterinary Services Center. This is the US government step that certifies the vet is accredited and the health certificate is legitimate.
USDA APHIS centers that handle endorsements:
- In person: APHIS VS National Center in Riverdale, MD; regional VS offices (call ahead for appointment availability)
- By mail: Ship the original signed certificate to the USDA APHIS office serving your state; allow 3–5 business days (standard) or 1–2 business days (expedited). USDA APHIS charges USD 38 per certificate for endorsement.
Because the health certificate must be issued within 10 days of travel, and endorsement takes 1–5 business days, the practical window is tight. For a travel date of Day 0:
- Day -10 to -8: vet appointment, health certificate signed
- Day -8 to -4: ship to APHIS or visit in person; endorsement returned
- Day -4 or later: endorsed certificate in hand, travel documents complete
Do not cut this closer than Day -7 for the vet appointment. APHIS can be delayed; holiday periods and high-volume periods add time. Have the Thai DLD import permit, microchip certificate, and rabies certificate ready before the vet appointment so the vet has all information to complete the health certificate in one visit.
—Airline Options from the USA to Thailand
Getting a pet from the USA to Thailand is the most logistically complex part of the move — not the Thai paperwork, but finding an airline that will carry your pet on the route and understanding the conditions. For a quote on pet transport to Thailand, Swift Cargo handles the cargo shipment coordination for pets not eligible for cabin travel.
In-Cabin (small pets only)
In-cabin pet carriage (pet in a carrier under the seat) is available on some routes for small dogs and cats (combined weight of pet + carrier typically under 8–10 kg). However, the route from the USA to Thailand requires at least one connection, and not all airlines allow in-cabin pets on all segments. Airlines that have historically offered in-cabin pet transport on transpacific routes: Thai Airways (on some routes), EVA Air, Japan Airlines (JAL). Confirm directly with the airline at the time of booking — policies change frequently and are enforced at check-in.
Checked Baggage (medium pets)
Pets travelling as checked baggage ride in the temperature-controlled cargo hold. This option is available on some routes for pets too large for in-cabin carriage but meeting the airline’s weight/size limits. Temperature and pressure conditions in modern aircraft holds are appropriate for pet travel, but confirm the airline’s specific temperature restrictions (many airlines suspend pet carriage in holds when ambient temperatures exceed 85°F/29°C at origin or destination).
Cargo Shipment (large dogs, pets not eligible for passenger cabin/baggage)
Large dogs (especially pure breeds above airline weight limits), snub-nosed (brachycephalic) breeds restricted by most airlines (English Bulldogs, French Bulldogs, Pugs, Shih Tzus, Persian cats, etc.), and pets whose owners are not flying on the same flight must travel as manifest cargo through an IATA-certified pet transport agent. The pet travels in a larger IATA-compliant crate in the cargo hold, shipped as freight rather than passenger baggage.
IATA Live Animals Regulations (LAR) govern the crate standards, minimum dimensions (the pet must be able to stand, turn, and lie down), ventilation, bedding, and food/water requirements for cargo shipments. An IATA-certified pet relocation agent arranges the cargo booking, coordinates with the airline cargo department, and handles the freight customs documentation on arrival in Thailand.
Airlines with dedicated air cargo pet handling on US–Thailand routes: Thai Airways Cargo, Singapore Airlines Cargo (via Singapore), Korean Air Cargo (via Seoul), Japan Airlines Cargo (via Tokyo). Confirm current policies and availability — cargo space for live animals must be booked separately from passenger tickets.
—Restricted and Prohibited Breeds
Thailand restricts the import of certain dog breeds under the Dangerous Animals Act. Breeds that may face import restrictions or require special permits include: American Pit Bull Terrier, American Staffordshire Terrier, Staffordshire Bull Terrier, Rottweiler, Dogo Argentino, Fila Brasileiro, Tosa, and some other large working breeds. The list is subject to change — confirm with the Thai DLD at the time of your import permit application. Attempting to bring a restricted breed without appropriate permits may result in the animal being refused entry.
Snub-nosed (brachycephalic) dogs and cats face additional airline carriage restrictions — many airlines refuse to carry them in holds or cabins due to respiratory risk. For brachycephalic breeds, cargo shipment through a specialist pet relocation agent is typically the only viable option.
—At Bangkok’s Suvarnabhumi Airport
US-to-Thailand flights typically arrive at Suvarnabhumi Airport (BKK). On arrival with your pet:
- Proceed through immigration (passport control) normally
- Collect your baggage and pet carrier (or collect your pet from the cargo hall if travelling as freight)
- Before exiting customs, present yourself at the Animal Import Inspection Counter (operated by Thai DLD, located within the customs hall)
- Present all documents: Thai DLD import permit, USDA APHIS-endorsed health certificate, microchip certificate, rabies vaccination record
- A DLD officer inspects the pet, scans the microchip, and reviews the documents
- If all documents are in order, the pet is cleared and you exit customs normally
The inspection typically takes 30–60 minutes. There is no mandatory quarantine for pets from the USA that arrive with correct documentation — quarantine is only applied if documents are incomplete or if the animal shows clinical signs of disease.
—Costs Summary
| Item | Approximate cost |
|---|---|
| ISO microchip implantation (if needed) | USD 40–100 |
| Rabies vaccination (if due) | USD 30–80 |
| USDA-accredited vet health certificate | USD 80–250 |
| USDA APHIS endorsement | USD 38 per certificate |
| Thai DLD import permit | THB 0–500 (nominal or free) |
| IATA-approved travel crate (if needed) | USD 50–200 depending on size |
| Airline pet carriage fee (in-cabin) | USD 100–250 per flight |
| Airline cargo pet fee (large pets) | USD 400–1,500+ depending on route, weight, airline |
| Pet relocation agent (if using) | USD 500–2,500 for full coordination |
The rabies titer test has a four-month clock. The test cannot be done until 30 days after the most recent rabies vaccination. The result must be endorsed by a USDA-accredited vet. The endorsed certificate must then be submitted to USDA APHIS for federal endorsement, which takes 10–14 business days. A pet owner who begins this process six weeks before a move date has already missed one of the non-negotiable steps. The animals who miss their flight are not victims of the airline or Thai immigration. They are the outcome of a timeline that started too late. This is not paperwork. It is a sequence with fixed durations.
Frequently Asked Questions
Do I need a USDA-endorsed health certificate to bring my pet to Thailand from the USA?
Yes. Thailand requires a health certificate issued by a USDA-accredited veterinarian and endorsed (countersigned and stamped) by USDA APHIS (Animal and Plant Health Inspection Service). The health certificate must be issued within 10 days of your travel date. APHIS endorsement takes 1–5 business days depending on method (in person or by mail). Budget 7–10 days minimum for the US documentation step and plan your vet appointment accordingly.
Is there a quarantine for pets entering Thailand from the USA?
No mandatory quarantine applies for dogs and cats from the USA that arrive with the correct documentation: Thai DLD import permit, USDA APHIS-endorsed health certificate, ISO-compliant microchip, and current rabies vaccination (administered at least 21 days before arrival and within the vaccine validity period). Your pet goes through a Thai DLD inspection at the airport livestock counter — typically 30–60 minutes — and is released. Quarantine is only applied if documents are incomplete or if the animal shows clinical signs of disease.
Will my US microchip work in Thailand?
Many US pets have 125 kHz (9-digit) chips from HomeAgain, AVID, or similar providers — these are not ISO 11784/11785 standard (134.2 kHz, 15-digit). Thailand’s DLD scans for ISO chips only. If your pet has a US-standard chip, have an ISO-compliant 15-digit chip implanted by a vet before completing the rest of the import documentation. The ISO chip must be implanted before the rabies vaccination recorded on the health certificate, so the chip number can be linked to the vaccine record.
Which airlines fly pets from the USA to Thailand?
There is no direct flight from the USA to Thailand that accepts in-cabin pets at this time (2026). Connections are required, and pet policies vary by airline and route segment. Thai Airways, EVA Air, and Japan Airlines (JAL) have historically accepted in-cabin small pets on some transpacific connections. Larger pets and restricted breeds must travel as cargo through an IATA-certified live animal handling program. Confirm all airline pet policies at the time of booking — policies change frequently and are enforced at check-in, not just at booking.
How far in advance should I start the pet import process?
Start 8–12 weeks before your intended travel date. The Thai DLD import permit should be applied for at least 30 days before arrival. Microchip implantation (if needed) should happen first, followed by rabies vaccination — then wait 21 days before travel is permitted. The USDA-accredited vet health certificate and APHIS endorsement must be completed within 10 days of travel. Working backward from your travel date: microchip and rabies vaccination at 10–12 weeks out; DLD import permit application at 8–10 weeks; vet certificate and APHIS endorsement in the final 7–10 days.
