More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the pan assembly is presented with a complete weighing machine
If imported together with the scale as a complete unit, the entire machine may be classified under the weighing machinery heading rather than as a part.
If the pan assembly is used in a machine performing a specific function other than weighing
If the assembly is integral to a wafer processing machine and not solely for weighing, it may be classified as a part of that machine under heading 84.79.
If the pan assembly is specifically designed for semiconductor manufacturing equipment
Parts solely or principally used in machines for manufacturing semiconductors may fall under heading 84.86, which takes precedence over other headings.

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 pan assembly is declared as a part of weighing machinery, not as a separate weighing device, to avoid misclassification
• Provide a detailed technical description and diagrams to the CBSA to support the classification
• Verify if the pan assembly qualifies for duty-free treatment under a free trade agreement by confirming the origin of the goods
