Import Tips
• Ensure the sheets are not converted beyond cutting to size; any punching or perforation would change classification
• The product must meet the weight and fibre thresholds; maintain supplier specifications for CBSA verification
• If the sheets are printed with programming instructions, they may fall in Chapter 49
