Import Tips
• Provide detailed chemical analysis certificates confirming ether-phenol structure to avoid reclassification under Chapter 29 salt provisions
• Ensure USP-grade documentation and stability data for stabilizers, as per Chapter Note 6(f), to prevent scrutiny during customs inspection
• Declare exact purity levels; impurities exceeding 1% may trigger additional testing for compliance with chemically defined compound requirements
