Producers' stocks of market pulp in Finland, Sweden, Canada and the United States rose in April by a more-than-expected 127,000 tonnes versus March to 1.59 million tonnes, Finland's forest industry said on Tuesday. North American and Scandinavian (Norscan) market pulp stocks are watched as an indicator of future trends in the key raw material, which in turn can affect paper prices though the historical link between pulp and paper prices has weakened. The average capacity utilisation rate throughout the Norscan region edged up to 94 percent in April from 93 percent in March, the Finnish Forest Industries Federation said in a statement.
