Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported within complete automatic data processing test system
Modular components of complete ADP systems classify under 8471 rather than separate electrical machines.
If as parts of oscilloscopes or spectrum analyzers
If designed specifically as replacement part for Chapter 90 instruments, classifies there instead.
Not sure which classification is right?
The Tariff Assistant works through the GRI rules on your specific product to reach the right HTS code — and can price the duty on it in the same conversation.
Import Tips & Compliance
• Document PXI chassis compatibility but emphasize standalone signal generation function
• Avoid common error of declaring under 8471.80 as ADP unit; focus on electrical signal generator role
• Calibrated units require proof of recent calibration for valuation purposes
