Import Tips
• Provide manufacturer's certification of catalytic grade vs. reagent grade to justify 3815 classification
• Ensure packaging prevents moisture absorption, which could alter composition and trigger reclassification
• Watch for misclassification as fertilizer additive (3102) if marketed for agriculture rather than catalysis
