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 residual lyes, a byproduct of the wood pulp manufacturing process. These lyes are a significant component of the pulp and paper industry, with applications ranging from chemical production to environmental remediation. As a key intermediate in the broader 47 (Pulp of wood or of other fibrous cellulosic material; recovered (waste and scrap) paper or paperboard) industry, 3804 plays an important role in the global supply chain for a wide range of paper and wood-based products.

Production process

Residual lyes are generated during the chemical pulping of wood, a process that separates cellulose fibers from lignin and other non-cellulosic components. The lyes are a complex mixture of organic and inorganic compounds, including lignin sulphonates, that are extracted and concentrated through various chemical and physical separation techniques. The specific production methods can vary depending on the pulping process (e.g., kraft, sulfite) and the desired properties of the final lye product.

Production inputs

The primary inputs for the production of 3804 residual lyes are the raw materials used in the wood pulp manufacturing process, such as 44 Wood and articles of wood; wood charcoal and other fibrous cellulosic materials. Additionally, the production may require various chemicals, energy sources, and specialized equipment for the pulping, extraction, and concentration of the lyes.

Production outputs

The main outputs of the 3804 industry are the residual lyes themselves, which can be further processed, concentrated, or chemically treated for a variety of applications. These lyes may be used as inputs for the production of 3803 Tall oil, whether or not refined, 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 other chemical products classified under different HS codes.
