Not required by Mexico, but strongly recommended. If a microchip number is listed on the health certificate, SENASICA will scan the chip on arrival and the number must match exactly — a mismatch will result in rejection of the certificate.

Required for pets over 3 months of age. There is no waiting period after vaccination — a pet can travel to Mexico immediately after receiving the rabies vaccine. Both 1-year and 3-year vaccines are accepted, provided the vaccine is within its valid period on arrival. Pets under 3 months of age are exempt from the rabies vaccination requirement. If a pet arrives without a valid rabies vaccine, the vaccination can be administered at customs by an official veterinarian before the import certificate is issued.

Both tick treatment and internal deworming are required within six months before arrival. A single combination product that covers both endo- and ectoparasites is accepted, provided the active ingredients are listed on the health certificate. The product name, active ingredients, and date of administration must be recorded. If ticks are found during the SENASICA physical inspection on arrival, samples will be sent to an official laboratory for testing at the owner's expense, and the pet may be held pending results.

Required for pets arriving from all countries except the United States and Canada. Valid for 15 days from the date of issue. Unlike most destinations, Mexico does not require the certificate to be issued or endorsed by an official government veterinarian — a private veterinarian is accepted, provided the certificate is on the clinic's official letterhead and includes the veterinarian's professional licence number (or equivalent). The EU Pet Passport is also accepted in place of a health certificate, as long as all sections are completed, signed, and stamped. The certificate must include the pet's species, breed, sex, date of birth, coat colour, and identifying marks; the rabies vaccination date and validity; a clinical health statement; and antiparasitic treatment details.

On arrival at any Mexican port of entry, the pet owner must contact SENASICA personnel at the OISA (Oficina de Inspección de Sanidad Agropecuaria). Officials will conduct a documentary and physical inspection of the pet. Once requirements are confirmed, SENASICA issues the Certificado Zoosanitario para Importación (CZI). No advance import permit is needed — the CZI is issued on arrival. For 1–2 pets, no fee applies. For 3 or more pets, a fee is charged and customs commercial import procedures apply.

The carrier or container must be clean on arrival. Bedding, toys, and any items made with ruminant-derived ingredients are not permitted inside the carrier and will be removed or destroyed. The carrier will be sprayed with a preventive disinfectant by SENASICA personnel on arrival. The pet's collar and leash may remain. One day's ration of dry pet food is permitted.
