Sodium Lignosulfonate Powder
Sodium lignosulfonate is a water-soluble anionic polyelectrolyte derived from the sulfite pulping process of wood pulp production. It falls under HTS 3804.00.5000 as a residual lye from wood pulp manufacture, chemically treated and concentrated for use as a dispersant, binder, and dust suppressant in industrial applications.
Calcium Lignosulfonate Liquid
Calcium lignosulfonate is a concentrated liquid residual lye from wood pulp sulfite digestion, used primarily as a concrete plasticizer and animal feed pellet binder. Classified under HTS 3804.00.5000 due to its origin as tall oil-free lignin sulfonates from the pulping process.
Ammonium Lignosulfonate Granules
Granulated ammonium lignosulfonate serves as a dust control agent and ceramic binder, produced from desugared lignin sulfonic acids in wood pulp spent liquors. HTS 3804.00.5000 covers this chemically treated residual lye excluding tall oil components.
Lignin Sulfonate Concrete Dispersant
This concentrated sodium-based lignin sulfonate acts as a high-range water reducer in ready-mix concrete, directly derived from black liquor of sulfite pulp mills. It qualifies for HTS 3804.00.5000 as a wood pulp manufacturing residual lye, chemically treated but retaining base composition.
Desugared Black Liquor Solids
Desugared solids recovered from spent sulfite pulping liquor, containing primarily lignin sulfonates for use in gypsum board production. HTS 3804.00.5000 includes such concentrated, chemically treated residual lyes from wood pulp manufacture.
Wood Pulp Lye Dispersant for Ceramics
Modified lignin sulfonate from concentrated softwood pulp lyes, serving as a deflocculant in ceramic slip casting. Falls under HTS 3804.00.5000 as it originates from wood pulp production residuals, excluding tall oil.
