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

HS v2022 Code: 470329

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

HS code 470329 covers chemical wood pulp, soda or sulphate, other than dissolving grades, that is semi-bleached or bleached, and derived from non-coniferous wood sources. This type of wood pulp is a critical raw material for the production of various paper and paperboard products, playing a vital role in the global paper industry and broader manufacturing supply chains.

Production process

The production of chemical wood pulp under HS code 470329 involves a multi-step process. First, non-coniferous wood is mechanically or chemically broken down into individual cellulose fibers. This is typically done through a pulping process using either the soda or sulphate (kraft) method. The resulting pulp is then subjected to a semi-bleaching or bleaching treatment to improve its brightness and purity before being dried and prepared for further processing or sale.

Production inputs

The main inputs required for the production of HS code 470329 wood pulp include non-coniferous wood as the primary raw material, as well as chemicals such as sodium hydroxide, sodium sulphide, and various bleaching agents. Specialized pulping and bleaching equipment, such as digesters, washers, and bleaching towers, are also essential for the manufacturing process.

Production outputs

The primary output of HS code 470329 is semi-bleached or bleached chemical wood pulp, which is then consumed by various downstream industries. This pulp is a key input for the production of 480100 Newsprint, 480400 Kraft paper and paperboard, and 481013 Composite paper and paperboard, among other paper and paperboard products.
