Ultrasonic essential-oil diffusers and aroma humidifiers designed for home use are classified under 8509.80. Although they use a piezoelectric transducer rather than a rotary motor, customs authorities in the US, EU, and UK have consistently placed household ultrasonic diffusers under 8509.80 as 'other' electromechanical domestic appliances (CBP Ruling N243896 and related). Nebulising diffusers (using an air pump rather than ultrasound) are also 8509.80. Candle-warmer diffusers using a heat lamp without a motor are 8516.79 (other electro-thermic appliances). Reed diffusers (no electricity) are classified under the product they contain — typically 3307.49 (preparations for perfuming rooms). Car diffusers that plug into the 12V socket are 8516.79 or 8543.70 depending on heating/ultrasonic function. Smart WiFi-enabled diffusers remain 8509.80 — the app control is ancillary.
