Import Tips & Compliance
• Verify purity levels (>99%) via Certificate of Analysis to confirm industrial classification and avoid food-grade HTS
• Include SDS and chemical passport for hazardous material handling during customs clearance
• Ensure proper labeling as 'not for food use' to prevent reclassification under food additive provisions
