Import Tips & Compliance
• > Ensure the powder is not mixed with other substances that could change its classification
• Provide a certificate of analysis showing MoO3 purity
• If the powder is doped for electronic use and in rod or cylinder form, it may still fall under Chapter 28, but if cut into wafers, it would be heading 38.18
