When approaching an international border with a checkpoint, you must meet customs requirements to cross.
Financial requirements, such as import duty, may also apply. Some jurisdictions require you to pay a percentage of the value of items you're bringing in, even if you don't plan to stay. This includes your pets, unless otherwise stated. Some jurisdictions require you to use a customs broker who pays these fees on your behalf. Understanding these financial customs requirements is essential for properly declaring items upon arrival.
You must declare all animals at international borders.
While most requirements apply during import or entry, some jurisdictions have separate export requirements for leaving that differ from the destination's import requirements. These may relate to health, finances, or both. Even though you're departing, you must meet these export requirements, as authorities may prevent you from leaving without proper documentation.
Customs rules change often, so always confirm current requirements with your airline and the destination's official animal import authority before you travel. Keeping your pet's PadsPass profile complete — microchip number, first scan date, and most recent rabies vaccination (the two most recent if possible) — helps you have the right records on hand at the border. Final acceptance of your pet always rests with the airline and the destination authority.
