USPS live animal mailing rules after the October 2026 update

USPS live animal mailing rules allow small, harmless, cold-blooded animals (fish, snails, worms, frogs, lizards), never snakes, turtles or turtle eggs. Publication 52 now requires a new 275 lb test double-wall weather-resistant corrugated box or equivalent and bars USPS-produced packaging, Flat Rate boxes included. GoatLabels prints the USPS label; Publication 52 compliance is the mailer's.
