Wood pulp obtained by a combination of mechanical and chemical pulping processes

HS v2017 Code: 4705

About wood pulp obtained by a combination of mechanical and chemical pulping processes

HS code 4705 covers wood pulp obtained through a combination of mechanical and chemical pulping processes. This type of pulp is a crucial raw material for the paper and paperboard industry, which is a significant contributor to the global economy. The production of 4705 wood pulp allows for the creation of a wide range of paper products, from high-quality printing and writing papers to packaging materials, making it an essential component of various industries.

Production process

The production of 4705 wood pulp involves a combination of mechanical and chemical pulping processes. Mechanical pulping uses physical methods, such as grinding or refining, to separate the wood fibers, while chemical pulping utilizes chemical reactions to break down the lignin that binds the fibers together. The resulting pulp is then further processed, often involving bleaching and other treatments, to meet the specific requirements of the end-use applications.

Production inputs

The main inputs required for the production of 4705 wood pulp include various types of wood, such as softwood and hardwood, as well as chemicals used in the chemical pulping process, such as sulfur-based compounds. Additionally, specialized machinery and equipment, such as pulp mills, refiners, and bleaching systems, are essential for the efficient production of this type of pulp.

Production outputs

The primary output of the 4705 wood pulp industry is the pulp itself, which is then used as a raw material in the production of a wide range of paper and paperboard products. These products may include 4801 Newsprint, in rolls or sheets, 4802 Uncoated paper and paperboard, of a kind used for writing, printing or other graphic purposes, and 4803 Toilet or facial tissue stock, towel or napkin stock and similar paper of a kind used for household or sanitary purposes, among others. The versatility of 4705 wood pulp makes it an essential component in the global paper and packaging industry.
