Firefighters have been tackling a blaze in a large warehouse at the Port of Tilbury since late last night.
Essex Fire and Rescue was called at midnight and told about 1,500 tonnes of woodchip was alight in a warehouse that measures 320ft by 150ft (100m by 30m).
Crews are expected to be at the scene for several days.
"The fire is completely restricted to the building and the level of smoke in the nearby area is minimal," a fire service spokesman said.
"Because the fire is so deeply positioned within the pile, firefighters are supporting the building's personnel in using internal cranes to move the materials.
"This is a gradual process and crews expect to remain at the scene for a number of days."
An eyewitness said the emergency vehicle "skidded in the rain on a sharp turn".
