Import Tips
• Provide process flow documentation proving lyes originate from soap boiling to distinguish from other industrial effluents
• Test for glycerol concentration and pH; high soap content may trigger reclassification under soap-stock headings
• Ensure waste classification compliance (non-hazardous) with SDS sheets to prevent EPA customs holds
