For cross-border trade, compliance is non-negotiable. Ensure the product carries UL, ETL (for North America), or CE and RoHS (for Europe) certifications. Since these mirrors are often installed in bathrooms, an IP44 or IP65 waterproof rating for the entire unit is mandatory. Technically, check for flicker-free drivers and integrated defogging pads with auto-off timers. If the mirror includes 'Smart' features (Android OS or Bluetooth), verify FCC or RED (Radio Equipment Directive) compliance to avoid customs seizures.
