As of January 2, 2012, tax-free liquid goods of more than 100 ml purchased at an airport outside the EU or onboard a non-EU flight may be brought into the passenger cabin of a connecting flight at Helsinki Airport.

The alleviation of the regulations concerning liquids will be conducted on a trial bases at Helsinki Airport until March 16, 2012, during which time the trial will be reviewed.

The liquid goods must be packed by the seller in a sealed, plastic bag, which is fully intact and unopened, and the receipt must be visible inside the bag.

All liquids, including the 100 ml liquid containers packed in a separate, transparent, one-litre plastic bag, must be presented by the passenger for screening at the security control.

The concession makes it possible for passengers to transport tax-free liquids in their carry-on baggage. Passengers may buy liquid products at, for example, Bangkok Airport and take them through the security control to a connecting flight at Helsinki Airport. Passengers should, however, be aware that the screening of liquids might somewhat slow down the process at the security control.

All EU states or all airports may not introduce the new practices. The current rules will still apply, among all, in Spain, France, Italy, Great Britain, Switzerland, Greece, Belgium, Bulgaria, Portugal and Estonia. This means, that the liquids carried by passengers who have to change flights at yet another airport after Helsinki, might still be confiscated.

The old regulations still apply to liquids purchased somewhere else than at the airport tax-free shops or onboard aircraft.
