Import Tips & Compliance
• Confirm the powder is not doped for electronic use, as doped silicon or selenium in wafer form would fall under Chapter 38
• Provide the exact stoichiometry (e.g
• SrMnO3) and particle size distribution on the customs declaration
• If the material is for fuel cell applications, check if it meets Canadian electrical safety standards
