Import Tips
• Provide technical documentation showing the pore size distribution and gas separation performance to support classification as activated carbon
• The CBSA may question whether the product is a molecular sieve rather than activated carbon, so be prepared to explain the distinction
• Consider obtaining a binding tariff classification ruling
