Import Tips
• Classify this as a gas filtration unit, not as a part of the polisher, to benefit from the specific heading
• Keep records of the HEPA filter grade and particle capture efficiency for CBSA verification
• Consider whether the collector is sold separately or with the polisher, as this affects classification
