Chemical wood pulp, soda or sulphate, other than dissolving grades
HS v2017 Code: 4703
About chemical wood pulp, soda or sulphate, other than dissolving grades
HS code 4703 covers the production of chemical wood pulp, a critical raw material used in the manufacturing of various paper and paperboard products. This industry plays a vital role in the global paper and packaging supply chain, providing the essential fibrous material required for the production of everything from newspapers and magazines to corrugated boxes and specialty papers. As a key component of the broader forestry and wood processing sector, the chemical wood pulp industry is an important contributor to national and international economies.
Production process
The production of chemical wood pulp under HS code 4703 typically involves a multi-step chemical process. The primary raw material, wood, is first mechanically or chemically debarked and chipped into small pieces. These wood chips are then cooked in a chemical solution, often containing sodium hydroxide and sodium sulfide, to dissolve the lignin that binds the cellulose fibers together. The resulting pulp is then washed, screened, and sometimes bleached to produce the desired color and quality of the final product.
Production inputs
The main inputs required for the production of chemical wood pulp under HS code 4703 include wood chips, typically sourced from softwood or hardwood trees, as well as various chemicals such as sodium hydroxide and sodium sulfide. Specialized machinery, including digesters, washers, and screening equipment, is also essential for the pulping and processing of the raw materials. Additionally, the industry relies on a reliable supply of energy, water, and transportation infrastructure to support the production and distribution of the finished pulp.
Production outputs
The primary output of the HS code 4703 industry is chemical wood pulp, which is then consumed by manufacturers of 4801 Newsprint, in rolls or sheets, 4802 (Uncoated paper and paperboard, of a kind used for writing, printing or other graphic purposes, and non-perforated punch-cards and punch tape paper, in rolls or rectangular (including square) sheets, of any size), 4803 Toilet or facial tissue stock, towel or napkin stock and similar paper of a kind used for household or sanitary purposes, cellulose wadding and webs of cellulose fibers, whether or not creped, crinkled, embossed, perforated, surface-colored, surface-decorated or printed, in rolls or sheets, and other paper and paperboard products. The chemical wood pulp produced under this code is an essential input for the broader paper and packaging industry.
