Import Tips
• Provide GC-MS analysis confirming >98% dibutyl sebacate purity to avoid mixture classification under 3824
• Include end-use declaration; cosmetic-grade requires additional FDA compliance documentation
• Watch for temperature control during shipping; improper storage can cause ester hydrolysis affecting classification proofs
