Due to an active USDA classification, every dog entering the US from Mexico needs a screwworm freedom certificate — separate from and in addition to the standard CDC low-risk pathway.
Everything you need to know about moving your dog or cat from Mexico to the US: CDC requirements, the active USDA screwworm certificate, Mexico’s SENASICA export process, costs, and timeline — all in one place.
A veterinarian-issued health certificate supports Mexico's SENASICA export certificate (CZE) application. This is separate from the USDA-required screwworm certificate for dogs.
Mexican-Authorized Veterinarian
The health certificate and screwworm freedom certificate are both issued by a veterinarian authorized by Mexico’s Competent Authority (SENASICA).
Required (Dogs Only, Screwworm Certificate)
This is separate from the CDC rabies pathway — confirm current status directly with USDA APHIS before traveling, since it’s tied to an active, evolving outbreak.
8 Days (SENASICA CZE)
The SENASICA export certificate (CZE) is valid for only 8 days once issued, so departure needs to follow closely behind it. The CDC Dog Import Form itself is valid for 6 months.
Required
Bring original documentation — the CZE requires a second in-person seal at a SENASICA office on travel day, so a printed or physical copy is needed regardless.
→ Screwworm freedom certificate currently required for every dog from Mexico
→ SENASICA’s CZE export certificate is required and free, but valid only 8 days
→ A readable microchip is required, with the number matching all records
→ Cats face no CDC/USDA rabies-related requirement
→ Entry is allowed at any US airport, seaport, or land border crossing
→ Assuming the CDC rabies pathway is the only requirement
→ Assuming Mexico has no export certificate process
→ Missing the CZE’s short 8-day validity window
→ Confusing the screwworm certificate with the CZE’s supporting health certificate
→ Not considering the land border option
Follow this timeline to make sure you complete everything on time for a smooth, stress-free travel day.
The active USDA screwworm certificate applies to every dog from Mexico regardless of CDC rabies-risk pathway.
USDA APHIS currently classifies Mexico as screwworm-affected due to an active outbreak. Every dog entering the US from Mexico needs a screwworm freedom certificate, signed by an authorized veterinarian within 5 days of shipment — this is layered on top of, not replaced by, the standard CDC low-risk pathway requirements.
✓ Confirm current screwworm certificate requirements directly with USDA APHIS before traveling.
✓ Schedule the vet visit for this certificate within the required 5-day window before shipment.
Arriving without this certificate could mean your dog is denied entry, even if every CDC requirement is met.
Mexico's export certificate is only valid for 8 days once issued.
Unlike some documents on other routes, the SENASICA Certificado Zoosanitario de Exportación is valid for only 8 days from issuance. If departure is delayed beyond that window, a new certificate is needed.
✓ Don't apply for the CZE too far in advance of your actual travel date.
✓ Confirm your flight or travel date is set before starting the CZE application process.
An expired certificate at the point of departure could delay or block your pet's travel.
Costs vary based on pet size, airline, season, and any additional Services.
Roughly $285–$640 (estimated) — microchip, vaccine, crate if flying, and an airline fee. SENASICA's CZE is free.

→ Yes, currently, for dogs. USDA APHIS classifies Mexico as screwworm-affected due to an active outbreak.
→ It must be signed by an authorized veterinarian within 5 days of shipment.
→ It applies regardless of CDC rabies pathway, and does not apply to cats.
→ Not from the CDC directly, but two Mexico-side documents function similarly.
→ A SENASICA CZE (export certificate) and, for dogs, the USDA screwworm certificate are both required.
→ A veterinarian-issued health certificate supports the CZE application.
→ Yes — the CDC allows entry at any US airport, seaport, or land border crossing.
→ The same requirements apply either way, including the screwworm certificate for dogs.
→ Driving means no airline fee or crate requirement.
→ No, for US mainland destinations.
→ Mexico’s CDC low-risk status means the high-risk-country quarantine pathway doesn’t apply.

Moving a pet from Mexico to the United States is one of the faster routes covered on this site — Mexico is CDC low-risk for dog rabies, so there’s no titer test or quarantine to plan around.
Due to an active New World Screwworm outbreak, USDA APHIS currently requires every dog entering the US from Mexico to be accompanied by a screwworm freedom certificate, signed by an authorized veterinarian within 5 days of shipment. This applies regardless of CDC rabies pathway and does not apply to cats. Because this is tied to an active outbreak rather than a stable classification, confirm current status directly with USDA before traveling.
Unlike Canada, Mexico’s SENASICA issues a Certificado Zoosanitario de Exportación (CZE) for pets leaving the country. It’s free, but processing takes 3 business days and the finished certificate is valid for only 8 days — departure needs to follow closely behind it.
The CDC’s low-risk pathway allows entry at any US airport, seaport, or land border crossing — a genuinely common option given Mexico’s shared land border with the US at crossings like San Diego/Tijuana, El Paso/Ciudad Juárez, and Laredo.
Most owners can manage this route without professional help, though the combination of the screwworm certificate and the CZE’s tight 8-day validity window makes timing coordination more important here than on a simpler route like Canada’s.
