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
