What decides the code
An ultrasonic humidifier is an electromechanical domestic appliance with a self-contained electric motor, classified under 8509.80.50.70.
- The humidifier is a domestic appliance with a self-contained electric motor, which places it in heading 8509.
- The unit is an ultrasonic humidifier, which is named in the statistical suffix under 8509.80.50.70.
- A humidifier that works without a self-contained electric motor, such as one driven only by heat, would fall outside heading 8509.
Common mistakes
- Classifying the humidifier in 8479 as a mechanical appliance with individual functions is wrong because heading 8509 covers domestic appliances with a self-contained electric motor.
