Is airport customs before or after security?

There is no single rule that works at every airport. Some customs phones are in the check-in hall, some are after security, and arrival customs may be in baggage reclaim.

Why this is the most important detail

If you reach the wrong side of security with freight, production cases or a carnet that still needs stamping, you can lose the time you needed to find an officer. Every Red Channel Finder record prioritises the security position first.

Common locations

Before security, near check-in or oversized baggage.
After security, near the exit from passenger screening.
In arrivals baggage reclaim, near a customs booth or red channel.
At a ferry port or seaport control point before boarding.
