Import Tips
• Verify purity certificate from supplier showing ≥94% by weight to confirm HTS 2909.49.30.00 classification; lower purity shifts to 2909.49.40
• Include SDS and chemical analysis reports in documentation for CBP review to avoid reclassification
• Ensure proper UN packaging for Group III chemical (non-hazardous) to prevent transport delays
