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 micro-embossing does not constitute 'further working' beyond cutting into rectangles, as per chapter note 10
• Declare the sheets as stock material, not as finished diagnostic devices
• Verify the sheets are not coated with reagents, which could shift classification to Chapter 38
