Import Tips & Compliance
• > Ensure the basket is declared as a part of a centrifuge, not as a general semiconductor manufacturing machine, to avoid misclassification
• Provide technical specifications and a clear description to the CBSA to support the tariff classification
• Consider obtaining a ruling from the CBSA in advance for high-value or frequent shipments
