Import Tips
• Ensure the product is clearly described as a ceramic electrical insulator on customs documentation to avoid misclassification
• Verify the alumina content (99.5%) and provide technical datasheets if requested by CBSA
• Consider the end-use application (e.g
• vacuum systems) to confirm it is not part of a larger machine
