Magnesium Lignosulfonate Granules from China
Magnesium lignosulfonate granules are produced by neutralizing lignin sulfonic acid from spent sulfite pulping liquor with magnesium compounds, used primarily as a binder in briquettes and foundry applications. HTS 3804.00.10.00 applies as it's a direct salt derivative from wood pulp manufacture.

Import Tips
• Submit process flow documentation proving derivation from sulfite wood pulp, not ammonium-based alternatives
• Test for heavy metal content (arsenic, lead) common in pulp byproducts; may require FDA prior notice if for feed use
• Use proper dust control during loading to prevent classification issues as hazardous particulate matter
