Saint Helena, Ascension and Tristan da Cunha sets its own requirements for bringing in dogs and cats. From any departure country your pet needs import permit, microchip, rabies vaccination, rabies antibody titre test and veterinary health certificate. The rules are the same for dogs and cats.

Quarantine on arrival is mandatory — 180 days; documents do not waive it. Order matters more than the list: the microchip goes in before the rabies vaccination, or the vaccination does not count.
