Can I handle US customs clearance myself when my pet arrives?

It depends on the port of entry. US airports are designated either as “formal” or “informal” ports of entry, and most airlines specify that at formal ports owners cannot self-clear and must use a registered broker. At informal ports, owner self-clearance is permitted, but Airpets strongly recommends using a broker regardless — customs procedures vary significantly between airports, and a missed step can lead to lengthy delays. Self-clearance is only sensible if you’re already familiar with both the process and the specific airport.
