About wood pulp; chemical wood pulp, dissolving grades

HS code 470200 covers the industry of chemical wood pulp, specifically the dissolving grades. This industry is a crucial component of the broader pulp and paper sector, which plays a significant role in the global economy. Chemical wood pulp is an essential raw material for the production of various paper and paperboard products, as well as a range of other applications, including textiles, pharmaceuticals, and food additives.

Production process

The production of chemical wood pulp, dissolving grades, involves a series of complex chemical and mechanical processes. The primary raw material is wood, which is typically sourced from softwood or hardwood trees. The wood is first debarked and chipped, then cooked in a chemical solution to break down the lignin and separate the cellulose fibers. This process, known as pulping, can be carried out using various methods, such as the sulfite or kraft (sulfate) processes. The resulting pulp is then further refined and purified to meet the specific requirements of the dissolving grades.

Production inputs

The main inputs required for the production of chemical wood pulp, dissolving grades, include wood as the primary raw material, as well as various chemicals, such as sulfur, sodium hydroxide, and other reagents, depending on the pulping process used. Additionally, specialized machinery and equipment, such as digesters, washers, and bleaching towers, are essential for the various stages of production.

Production outputs

The primary output of HS code 470200 is chemical wood pulp, dissolving grades, which is then used as a raw material in the production of a wide range of products. These include 470710 (Recovered (waste and scrap) paper or paperboard), 480100 Newsprint, in rolls or sheets, 480200 Uncoated paper and paperboard, of a kind used for writing, printing or other graphic purposes, and 540700 Woven fabrics of man-made filament yarn, among others. The dissolving grades of chemical wood pulp are particularly important for the production of viscose and other cellulose-based textile fibers.
