Import Tips
• Verify purity certificate and USP compliance documentation to meet FDA import requirements for pharmaceutical ingredients
• Ensure proper labeling as 'sodium hydrogencarbonate' or 'sodium bicarbonate' with CAS number 144-55-8 for CBP classification
• Avoid misclassification as baking soda for retail; bulk pharma shipments require chemical analysis certificates
