Import Tips
• Verify purity via certificate of analysis to confirm classification as chemically defined cobalt oxide under Chapter 28 notes
• Ensure SDS includes CAS number (1317-38-0) for customs; avoid misclassification as alloys if metallic impurities exceed limits
• Declare exact Co content; commercial grades may shift to 2822 if impure
