Import Tips
• Ensure the plates are presented as unmounted polarizing material, not as parts of microscopes, which would be classified under heading 90.11 or 90.13
• Provide CBSA with specifications on extinction ratio and material type
• Confirm if the plates are considered optical elements requiring specific import documentation
