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

HS code 470429 covers chemical wood pulp, sulphite, (other than dissolving grades), semi-bleached or bleached, of non-coniferous wood. This type of wood pulp is a crucial raw material for the production of various paper and paperboard products, including printing and writing papers, tissue papers, and specialty papers. The global wood pulp industry plays a significant role in the broader paper and forest products sector, which is an important contributor to many national economies worldwide.

Production process

The production of chemical wood pulp under HS code 470429 involves a multi-step process. First, non-coniferous wood, such as hardwoods, is mechanically or chemically debarked and chipped. The wood chips are then cooked in a sulphite liquor, which dissolves the lignin and separates the cellulose fibers. The resulting pulp is then washed, screened, and may undergo further bleaching or semi-bleaching to achieve the desired brightness and purity levels.

Production inputs

The main inputs required for the production of chemical wood pulp under HS code 470429 include non-coniferous wood as the primary raw material, as well as chemicals such as sulphite liquor, bleaching agents, and various processing chemicals. Specialized pulping and papermaking machinery, such as digesters, washers, and screens, are also essential for the production process.

Production outputs

The primary output of HS code 470429 is chemical wood pulp, which is a key input for the production of various paper and paperboard products. This pulp may be further processed and consumed by manufacturers of 480100 Newsprint, in rolls or sheets, 480400 Kraft paper and paperboard, uncoated, in rolls or sheets, 480524 Uncoated paper and paperboard, of a kind used for writing, printing or other graphic purposes, and other related 4805 Other uncoated paper and paperboard, in rolls or sheets, not further worked or processed than as specified in Note 3 to this Chapter.
