Metsä Group will restart its Joutseno pulp mill on 8 December 2025, ending a production shutdown that began in June. Concurrently, the company will initiate an approximately one-month production curtailment at its Rauma pulp mill, starting 15 December 2025, with a gradual restart scheduled from 7 January 2026. The adjustments are a response to current market demand for long-fibre softwood pulp.

The company stated that the market situation for softwood pulp is expected to remain uncertain into the new year, prompting preparations for significant additional production curtailments at the Joutseno mill during 2026.

Metsä Fibre CEO Ismo Nousiainen confirmed the operational adjustments are intended to align output with market conditions.

Metsä Group's pulp and sawmill business Metsä Fibre produces not only pulp and sawn timber but also other bioproducts such as biochemicals and bioenergy.
