About wood pulp; chemical wood pulp, sulphite, (other than dissolving grades), semi-bleached or bleached, of coniferous wood

HS code 470421 covers chemical wood pulp, sulphite, (other than dissolving grades), semi-bleached or bleached, of coniferous wood. This type of wood pulp is a crucial raw material for the paper and paperboard industry, which is a significant contributor to the global economy. It is used in the production of a wide range of paper products, from printing and writing paper to tissue and packaging materials.

Production process

The production of chemical wood pulp, sulphite, (other than dissolving grades), semi-bleached or bleached, of coniferous wood involves several key steps. First, the raw material, which is typically softwood logs, is mechanically or chemically processed to separate the cellulose fibers from the lignin and other non-cellulosic components. The resulting pulp is then subjected to a bleaching process, which removes any remaining lignin and impurities, resulting in a bright, high-quality pulp suitable for various paper and paperboard applications.

Production inputs

The main inputs required for the production of HS code 470421 wood pulp include coniferous wood logs, chemicals such as sulfur dioxide and calcium bisulfite for the sulphite pulping process, and energy sources for the various processing steps. Additionally, specialized machinery and equipment, such as pulp digesters, bleaching towers, and drying equipment, are essential for the efficient production of this type of wood pulp.

Production outputs

The primary output of HS code 470421 is semi-bleached or bleached chemical wood pulp, which is a key input for the production of various paper and paperboard products. This pulp may be further processed and combined with other materials to create a wide range of paper-based goods, including 480100 Newsprint, in rolls or sheets, 480400 Kraft paper and paperboard, and 481013 Toilet or facial tissue stock, towel or napkin stock and similar paper for household or sanitary purposes.
