01Classify the intended use
State what the device does, where it contacts hair, skin or the body, who uses it, duration, dry or wet environment and prohibited uses. Confirm whether the product remains a household appliance or enters another regulatory category. Shape and marketing language cannot decide classification.
02Normalize electrical and model fields
Request model and revision, rated voltage, frequency, power, plug, cord or adapter, battery and charger, controls, modes, heating or motor system, firmware, attachments, contact materials, cleaning method and package contents. Quote different destination configurations separately.
03Separate existing and custom work
Identify standard housing, color, logo, attachments, prompts, firmware, manual and carton options. Record tooling, engineering, sample rounds, quantities, lead time and evidence impact for every change. A new attachment or heating control can matter beyond appearance.
04Run controlled sample observations
Inspect ratings, construction, cord entry, ports, controls and attachments before power. Then test only applicable functions with defined supply, setting, tool, distance, time and rest interval. Compare multiple units and stop for abnormal heat, odor, noise, vibration, smoke, swelling or intermittent power.
05Match technical evidence
Create a destination matrix for electrical safety, EMC, radio, battery, ingress, contact materials, labels and instructions. Ask qualified laboratories to confirm applicable standards and whether reports cover the exact hardware, firmware, power supply and attachments. Do not borrow evidence from a visually similar model.
06Review claims and customer instructions
Tie temperature, airflow, speed, charge, runtime, waterproof, salon, wellness or health statements to a named method and evidence. Keep cosmetic experience separate from therapeutic claims. Check that instructions explain setup, safe use, attachments, cleaning, storage and destination-specific warnings.
07Pilot quality and return handling
Inspect pilot units for configuration, cosmetics, controls, attachments, charging, package contents and instruction version. Track no-power, intermittent, heat, odor, noise, attachment, cleaning and damage returns separately. Quarantine safety symptoms and require declared-change review before reorders.
