Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If incorporating sound recording or reproduction functions
Devices with primary audio recording capability shift to heading 8519 sound recording apparatus.
If for instruments measuring electrical quantities with generation
If primary function becomes measurement rather than generation, classifies under Chapter 90.
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
• Specify audio frequency range (20Hz-20kHz) to distinguish from RF generators
• Include distortion and noise specs to validate precision signal generator classification
