Static converters (HS code(s): 850440)

Proposal for Amendments to the Legal Inspection Requirements for Three Power Supply Equipment, Including Uninterruptible Power Supplies; (6 page(s), in English), (4 page(s), in Chinese)

The proposed amendments cover three product items: uninterruptible power supplies (UPS), static converters, and other switch mode power supplies. For UPS, the amendments update the applicable inspection standards by adopting the latest version, with a view to enhancing product safety and aligning with current international standards. No substantive change is proposed for static converters; they are included in the amended scope solely as a result of product regrouping and to provide business operators with a more comprehensive overview of the applicable requirements. For other switch mode power supplies, the amendments introduce alternative inspection standards which business operators may use to demonstrate compliance with the regulatory requirements.
