Import Tips
• Include pulp mill origin certification to distinguish from synthetic sulfonates that might classify elsewhere
• Declare exact concentration and Brix value; highly diluted solutions risk scrutiny as waste liquids
• Comply with DOT shipping regs for corrosive liquids (pH typically <2) with appropriate UN packaging
