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
