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

HS code 470321 covers chemical wood pulp, soda or sulphate, (other than dissolving grades), semi-bleached or bleached, of coniferous wood. This type of wood pulp is a crucial raw material for the global paper and paperboard industry, which is a significant contributor to the global economy. The production and trade of this commodity play a vital role in meeting the world's demand for various paper products, from printing and writing paper to packaging materials.

Production process

The production of chemical wood pulp under HS code 470321 involves a multi-step process. First, coniferous wood, such as pine or spruce, is mechanically or chemically broken down into individual wood fibers. The wood fibers are then treated with a chemical solution, typically containing sodium hydroxide and sodium sulfide, to remove lignin and other non-cellulosic components. This process, known as the kraft or sulphate process, results in a semi-bleached or bleached wood pulp that is suitable for a wide range of paper and paperboard applications.

Production inputs

The main inputs required for the production of chemical wood pulp under HS code 470321 include coniferous wood as the primary raw material, as well as chemicals such as sodium hydroxide and sodium sulfide for the pulping process. Additionally, specialized machinery and equipment, such as digesters, washers, and bleaching towers, are necessary to carry out the various stages of production.

Production outputs

The primary output of HS code 470321 is chemical wood pulp, which is a key ingredient in the manufacture of various paper and paperboard products. This wood pulp may be further processed and combined with other materials to create a wide range of paper-based goods, including 480100 Newsprint, 480400 Kraft paper and paperboard, and 481013 Composite paper and paperboard, among others.
