Residual lyes from the manufacture of wood pulp, whether or not concentrated, desugared or chemically treated, including lignin sulphonates, but excluding tall oil of heading no. 3803

HS v2022 Code: 3804

About residual lyes from the manufacture of wood pulp, whether or not concentrated, desugared or chemically treated, including lignin sulphonates, but excluding tall oil of heading no. 3803

HS code 3804 covers a critical byproduct of the wood pulp manufacturing industry - residual lyes. These lyes, which may be concentrated, desugared, or chemically treated, play a vital role in the broader pulp and paper supply chain. As a key input for various downstream industries, the 3804 product category is an essential component of the global economy's resource utilization and sustainability efforts.

Production process

The production of residual lyes under HS code 3804 involves the processing of spent liquors generated during the manufacture of wood pulp. This includes the chemical treatment and concentration of the lyes, which can contain valuable compounds such as lignin sulphonates. The specific techniques employed may vary depending on the desired properties and applications of the final product.

Production inputs

The primary inputs for the 3804 industry are the spent liquors and byproducts from wood pulp production, which serve as the raw materials. Additionally, the industry may require specialized equipment and machinery for the concentration, desugaring, and chemical treatment of the lyes. Energy sources and water are also important inputs for the various processing steps involved.

Production outputs

The main output of the 3804 industry is the residual lyes, which can be further refined and utilized in a variety of applications. These lyes may find use as 3802 Activated carbon; activated natural mineral products; animal black, including spent animal black, 3805 Gum, wood or sulphate turpentine and other terpenic oils produced by the distillation or other treatment of coniferous woods; crude dipentene; sulphite turpentine and other crude para-cymene, and 3809 (Finishing agents, dye carriers to accelerate the dyeing or fixing of dyestuffs and other products and preparations (for example, dressings and mordants), of a kind used in the textile, paper, leather or like industries, not elsewhere specified or included).
