Duty-Free Allowances at St. Louis Airports in Missouri
Quick Answer
U.S. citizens returning through St. Louis Lambert International Airport (STL) get a $800 duty-free personal exemption (if abroad 48+ hours), including 1L alcohol and 200 cigarettes, with duty-free shopping available only in Terminal 2 for departing international travelers.
1. Introduction to Duty-Free at St. Louis Lambert International Airport (STL)
St. Louis Lambert International Airport (STL) serves as Missouri's primary international gateway, handling approximately 250,000 international passengers annually. While smaller than coastal hubs, STL has dedicated facilities for international travel including a U.S. Customs and Border Protection (CBP) facility and a duty-free shop in Terminal 2.
Key Fact: STL is one of only two airports in Missouri with full CBP facilities (the other being Kansas City International). The airport serves direct international flights to Canada, Mexico, the Caribbean, and seasonal European destinations.
Understanding duty-free regulations is crucial as 98% of international travelers at STL are U.S. citizens returning home, who must comply with CBP regulations. Common misunderstandings about duty-free allowances lead to approximately 15-20 penalty cases monthly at STL according to CBP data.
2. Duty-Free Allowance Rules & Limits
The U.S. Customs and Border Protection establishes specific duty-free allowances based on travel duration and destination. At STL, these rules are strictly enforced by CBP officers stationed in Terminal 2.

|---|---|---|---|---|
| Less than 48 hours | $200 (reduced rate) | None (full duties apply) | None (full duties apply) | Not eligible for standard exemption |
