Import Tips & Compliance
• Ensure the apparatus is not a complete lithography machine — if it includes exposure units, it may be classified under 84.86
• Document the spray pressure and nozzle design for CBSA review
• Verify if the developer chemicals require special handling declarations under Canadian transport regulations
