Import Tips
• Verify purity certificate (typically 95%+ ethoxyquin) as impurities affect classification; ensure SDS includes CAS 91-53-2 and quinoline structure confirmation
• Common pitfall: misclassification as general feed additive under Chapter 23 - provide chemical analysis to prove it's a separate organic compound
