Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If sold as a basic alarm set without ionization chamber
Non-ionizing interconnected alarms are under fire alarm systems in 8531, based on electrical signaling rather than radiation.
If part of a smart home automation system with app control
Integrated smart systems may classify under machines having individual functions in 8479 if beyond simple detection.
If for oscilloscopes or monitoring components in industrial kits
Components for radiation monitoring without smoke-specific function go to 9030 for oscillo/printed circuit instruments.
