I could imagine the reason being that the statistics only cover production occurring at facilities located in Finland. Doesn’t Kemira have 4 plants in Finland (Harjavalta, Pori, Joutseno, Kuusankoski) and nearly 60 plants globally?
A significant portion of that Finnish capacity is for the paper industry, about which Statistics Finland mentioned the following:
The value of new orders developed most poorly in the paper industry. Companies in the sector received 1.1% fewer orders in March than a year earlier.
Of course, two of the Finnish plants are Water Solutions plants, but they certainly also supply the paper side.
