Five fire crews were called to a building at the Port of Felixstowe after smoke was seen billowing from a window.
The crews were called to the empty building in Dock Road around 2.15pm Monday, June 7, after an automatic alarm was set off inside.
A further five crews were also on standby.
A spokesman for the Suffolk Fire and Rescue Service said crews saw smoke on their arrival and worked to establish whether a fire had spread.
All crews stood down and returned to their bases shortly after 3pm.
The spokesman added no-one was inside the building at the time of the fire and no injuries have been reported.
