European Transport Commissioner Siim Kallas on Friday instructed security experts to work out tightened security checks on air cargo, but warned them against meaningless measures that hamper business.
The move has been requested following the recent discovery of explosive devices sent from Yemen and Greece through regular services.
However, boosting security checks on air cargo will not be enough to tackle the terror threat, he said.
"The recent events highlight the need for more coordination at EU level," Kallas said. He emphasized that the priorities are to protect citizens while retaining an efficient air transport system.
"We should remain smart: simply adding more layers of cargo screening would be hard to implement, and cause great operational difficulties. We need an approach based on risk assessment, better integrated with intelligence; and we need to use a range of control methods in combination," Kallas said.
Mail bombs are becoming a common weapon among terrorists and militants around the world.
A recent attempt to send explosive-laden parcels from Yemen to synagogues in Chicago was linked to an al Qaeda cell.
Earlier this year a senior official at the Greek public order ministry was killed in a blast from a letter bomb addressed to the minister.
