Import Tips
• Confirm basic salt formula via spectroscopy; mislabeling as simple CoCO3 can cause reclassification
• Include MSDS showing <0.1% heavy metals; cobalt compounds trigger environmental import scrutiny
• For feed-grade, obtain FDA prior notice; bulk shipments need proper venting to prevent moisture caking
