Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the scale has a sensitivity of 5 cg or better
Balances with high sensitivity are classified separately under heading 84.23, not as other weighing machinery.
If the scale is integrated into a crystal growth machine
If the scale is a component of a machine performing a specific function, Section XVI Note 4 may classify the whole machine under its principal function.
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
• Confirm the scale's sensitivity is less than 5 cg to avoid classification as a balance under 8423.20.00
• Provide evidence of its use in semiconductor manufacturing to support classification
• Consider if the scale is part of a larger machine for classification purposes
