Import Tips
• Confirm the block is irregular in shape, not cut to a regular geometric form, to maintain primary form classification
• Document that no fillers or reinforcing agents were added, as these would exclude it from heading 40.02
• Provide a material safety data sheet (MSDS) for CBSA clearance
