Finland belongs to a common import regime: the requirements are the same across 27 countries, and paperwork done once works for all of them. There is no single set for everyone: what exactly is needed — microchip, rabies vaccination, rabies antibody titre test, parasite treatment, pet passport, import declaration and veterinary health certificate — depends entirely on the country you fly from. The rules are the same for dogs and cats.
The titre test sets the pace: blood is drawn no earlier than 30 days after the vaccination, and entry is allowed no earlier than 90 days after the draw. Pets may not enter through just any airport: there are 19 designated points. Order matters more than the list: the microchip goes in before the rabies vaccination, or the vaccination does not count. 8 carriers in our directory fly direct to Finland, and their pet conditions differ.
