Södra has increased the price of its softwood pulp in Europe to USD 870 per tonne.
The pulp producer said the move was “due to low global softwood pulp stocks and solid demand”.
It made the increase for the market price of NBSK in Europe on 1 June 2015.
The company also reported an operating profit for the first four months of 2015 of SEK 941m.
Sales increased 7% to SEK 6,243m and the operating margin improved by 15%.
Chief executive Lars Idermark said: “The year started well for Södra, with healthy sales and strong results.
“The market has been stable, prices relatively good and the currency situation favourable. Production has also been efficient and we are seeing the results of continued rationalisation.”
Demand for pulp remained stable, but the company said the currency trend with a strengthened USD against the EUR led to a slightly lower world market price for NBSK.
Södra added that earnings improvement for the first four-month period is the result of “healthy demand for Södra’s products and services and a favourable currency situation”.
