Import Tips
• Ensure the EMD is clearly identified as manganese dioxide (MnO2) with a purity certificate to support classification under 2820.90.00
• Declare the end use (battery manufacturing) to the CBSA if asked, as this may affect inspection priorities
• Keep shipping documents and lab analysis readily available in case of verification
