Emergency services were called to the incident just before midday.
A police spokesperson said cordons were put in place around the baggage area and passengers were taken off the plane as a precaution.
Specialists determined that the powder posed no threat, the spokesperson said.
It was not known what the powder was or where the flight had arrived from.
