Import Tips
• Provide a detailed specification sheet showing the chemical formula and purity to confirm it is MnO2 and not a mixed oxide
• If the powder is blended with carbon or other additives for battery use, verify whether it still qualifies as a pure oxide under Chapter 28
• Be prepared to explain the production process (natural vs. synthetic) if requested by the CBSA
