Car Cigarette Lighter Power Supplies (Item 3): CNS 15936 (2016), CNS 15598-1 (2020).
All Four Categories: Additionally, CNS 15663 Section 5 (2013 edition) for restricted substance labeling.
Conformity Assessment Procedures:
Items 1, 3, 4: Registration of Product Certification (Type Test Mode + Declaration of Conformity Mode).
tem 2 (Wireless Chargers): Type Approval with Batch Inspection OR Registration of Product Certification (Type Test Mode + Declaration of Conformity Mode).
Hazardous Substance Labeling (RoHS-like): All listed products must comply with CNS 15663 (2013 edition) Section 5, requiring specific labeling on the product, packaging, label, or manual regarding the content of restricted substances (Pb, Cd, Hg, Cr+6, PBB, PBDE). markings are mandated, including optional webpage disclosure if the URL is clearly marked
BSMI Mark: Products must bear a BSMI inspection mark, including an identification number with applicant code and hazardous substance content information.
Transition for Item 4 (Static Converters): Products already certified under IEC 61558-1 (2009) may undergo differential testing by the original designated laboratory for conversion to the new standard. Existing certificates remain valid until expiry. However, renewals or new applications submitted from July 1, 2027, must demonstrate compliance with the new CNS 61558-1 (2026) standard.
