Using SJU on air freight documents

The three-letter IATA code SJU is what goes on an air waybill, a booking and a flight schedule for Luis Munoz Marin International Airport, San Juan; the four-letter ICAO code TJSJ identifies the same airport in flight plans and air-traffic control and does not appear on cargo paperwork. A forwarder quotes airport-to-airport between two IATA codes unless the booking is door-to-door, so the code fixes where the rate applies.

For a US import, Luis Munoz Marin International Airport is also a customs port of entry. The Census Schedule D list names it as port 4913, and that four-digit code — not SJU — goes in the port field of CBP Form 7501. Airlift coordinates entry filing through our licensed broker network.

Schedule D codes are a US-only system, so SJU has none. If SJU is your origin, the code that matters at the border is the one for your US airport of entry — every US airport page in this tool shows it where the Census list names the airport.
