Import Tips
• Include REACH or TSCA certification if destined for US manufacturing to prove regulatory compliance
• Verify no sugar imide contamination; mislabeling leads to reclassification under 2925.19.30
• Use temperature-controlled shipping (<40°C) as succinimide is hygroscopic; document to prevent decomposition claims
