Import Tips

• Verify purity and chemical composition via lab analysis to confirm classification as synthetic manganese dioxide, avoiding misclassification as natural mineral products

• Obtain Material Safety Data Sheets (MSDS) and ensure packaging complies with UN regulations for oxidizers during transport

• Declare battery-grade specifications if applicable, as end-use documentation may be required for customs valuation
