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 global paper and paperboard industry, enabling the production of a wide range of paper products used across numerous sectors. As a major component of the forestry and wood processing industries, 470329 wood pulp plays a significant role in the broader economy.

Production process

The production of 470329 wood pulp involves a multi-stage chemical pulping process. Non-coniferous wood, such as hardwoods, is first mechanically chipped into small pieces. These wood chips are then cooked in a chemical solution, typically containing sodium hydroxide and sodium sulfide, to break down the lignin and separate the cellulose fibers. The resulting pulp is then washed, screened, and may undergo further bleaching or chemical treatment to achieve the desired level of whiteness and purity.

Production inputs

The key inputs for the 470329 wood pulp industry include non-coniferous wood sources, such as 440320 Wood in the rough, non-coniferous, as well as various chemicals like sodium hydroxide and sodium sulfide. Specialized pulping and bleaching equipment, as well as significant amounts of water and energy, are also essential for the production process.

Production outputs

The primary output of the 470329 wood pulp industry is the semi-bleached or bleached chemical wood pulp, which is then consumed by various 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 sheets, other than paper of heading 4801 or 4803 and 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.
