For the North American market, UL or ETL certification is essential to ensure electrical safety. For the European Union, the CE mark and RoHS compliance are mandatory to verify that the product meets health, safety, and environmental protection standards. If you are sourcing for the UK, ensure the product carries the UKCA mark. Always request official test reports from the supplier to confirm the internal wiring and plug configurations meet the destination country's specific voltage (e.g., 110-120V for US, 220-240V for EU/UK).
