HELSINKI — Finnish forest products group UPM has announced temporary production curtailments at its pulp mills in Kaukas and, potentially, Pietarsaari. Production at the Kaukas mill is scheduled to be suspended for approximately six weeks from 3 August. UPM is also preparing for a possible temporary production stoppage at its Pietarsaari mill in October. The company said the measures are aimed at optimising production volumes and wood procurement. The curtailments are also intended to safeguard profitability under current market and cost conditions.
