Import Tips & Compliance
• Provide detailed chemical analysis certificates confirming purity and acyclic structure to avoid misclassification under Chapter 28 inorganic acids
• Ensure proper labeling with CAS number (123-99-9) and COA for FDA compliance if destined for cosmetics
• Verify packaging meets UN standards for corrosive organic acids to prevent transport delays
