However, the largest producer is Chile, as well as Finland, the United States, Russia, and Sweden. . Because wood pulp can be directly made into paper in foreign countries, when my country imports wood pulp, in order to facilitate the transportation, all the wood pulp blocks are purchased, which are then melted during papermaking.
