As electrical heating appliances, these products must meet strict safety standards. For the US market, UL (Underwriters Laboratories) or ETL certification is essential. For the European market, CE marking, RoHS (Restriction of Hazardous Substances), and GS (Geprüfte Sicherheit) certifications are required. Additionally, verify that the SAA certification is present if shipping to Australia. Always request test reports for the power cord and plug to ensure they match the destination country's voltage (e.g., 110V for US, 220V for EU/UK).
