Chemical wood pulp, soda or sulphate, other than dissolving grades

HS v2022 Code: 4703

About chemical wood pulp, soda or sulphate, other than dissolving grades

HS code 4703 covers the classification of chemical wood pulp, produced using the soda or sulphate process, excluding dissolving grades. This industry is a critical component of the global paper and paperboard manufacturing sector, providing essential raw materials for a wide range of products. The production of chemical wood pulp under this code is a significant economic activity, with applications spanning packaging, printing, and various specialty paper goods.

Production process

The production of chemical wood pulp under HS code 4703 primarily involves the soda or sulphate (kraft) pulping process. This process uses chemical reagents, heat, and pressure to break down the lignin in wood fibers, separating the cellulose pulp from the other wood components. The resulting pulp is then washed, screened, and may undergo further processing, such as bleaching, to meet the specific requirements of end-users.

Production inputs

The main inputs for the production of chemical wood pulp under HS code 4703 include various types of wood, such as softwood and hardwood species, as well as chemical reagents like sodium hydroxide, sodium sulfide, and other additives. Specialized machinery, including digesters, washers, and pulp dryers, are also essential for the pulping and processing operations.

Production outputs

The primary output of the industry covered by HS code 4703 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.
