Not sure which classification is right?
The Tariff Assistant works through the GRI rules on your specific product to reach the right tariff item — and can price the duty on it in the same conversation.
Import Tips & Compliance
• Ensure the quartz blanks are classified as piezo-electric quartz and not as other synthetic stones, as this determines the applicable duty rate
• Provide detailed product specifications, including cut type (AT-cut) and intended use, to CBSA to support the classification
• Verify that the goods are not mounted or set, as that would change the tariff classification
