Import Tips
• Provide detailed chemical analysis certificates confirming adipic acid derivation to avoid reclassification
• Ensure proper UN-approved packaging for corrosive amine salts to comply with DOT and IMDG regulations
• Declare exact purity levels (typically >98%) as impurities may affect duty treatment under chapter notes
