Import Tips
• Document the silicon doping process and the block's semi-manufactured status for CBSA classification
• Verify that the blocks are not considered separate chemical elements, which would be excluded by chapter note 1
• Consider whether the blocks could be classified as parts of batteries if imported with other components
