Import Tips
• Classify the gearbox as a part of crystal growing machines under 8475.90.00, not as a general gearbox under heading 84.83
• Provide CBSA with the make and model of the crystal puller it is intended for to support the classification
• If the gearbox is imported with other components, ensure it is not part of a complete machine, which would change the tariff classification
