Air passengers travelling from European Union countries are to be restricted on how much liquid they can take on board.
Airport security measures have been blamed for causing delays
The European Commission has proposed limiting liquids to 100ml containers which must fit into a transparent, re-sealable plastic bag.
The rules are likely to be agreed next week and adopted in November.
Earlier, the Department for Transport said a hand-luggage liquids ban will remain on UK flights to the US despite the Americans easing restrictions.
The US has announced liquids bought from secure airport sites would now be allowed on planes.
But the DfT said liquids would still not be allowed on US-bound flights from the UK even if purchased "airside".
Restrictions were put in place after an alleged plot to blow up transatlantic airliners was foiled on 10 August.
Other rules agreed by the European Commission mirror the restrictions already in place in the UK.
The rules would limit the size of carry-on bags to a maximum of 56cm x 45cm x 25cm (22in x 17.75in x 9.85in approx), which is the same as presently in the UK.
Exceptions could be made for musical instruments and some other items.
Larger sized liquids can be bought the other side of security.
Passengers will be required to take off their coats and remove laptops and "large electrical items" from their bags at security checks.
In the UK, a total ban on hand luggage was initially brought in after the alleged plot was foiled.
The security measures have been blamed for causing delays and for costing airlines.
