Hi Chuck, my understanding of the Chinese regulation for CCC is that it is only applicable to finished products that are listed in the catalogue (like an external switch mode power supply that may be brought to market as a separate product) or parts of finished products that are accessible to the end user (like cord and plug). Therefore I assume that CCC is not required for internal switch mode power supplies that are not accessible to the user during normal use. In case of doubt, I recommend to check with your local representative or distributor/importer in China.

Should they have CCC as it is a requirement for that category code?

CHINA QUALITY CERTIFICATION CENTRE-Notice and Bulletin (cqc.com.cn)<https://www.cqc.com.cn/www/english/c/2023-02-09/559801.shtml>). This means even if your product is exempt from mandatory CCC certification (i.e. is not included in the product catalogue cited in the web page), but has a cord and plug, these have to be CCC certified. Details on certification rules can be found at CHINA QUALITY CERTIFICATION CENTRE-Certification Scope and Rules (cqc.com.cn)<https://www.cqc.com.cn/www/english/c/2014-09-05/511131.shtml> and 康捷 (cqc.com.cn)<https://cqc.com.cn/www/chinese/rootfiles/2014/09/05/1409864510109129-1409864510261077.pdf>, that references Chinese standard GB 15934 which is the Chinese adoption of IEC 60799.

Do not click links or open attachments unless you recognize the sender. All, I was talking with a client recently about shipping line cords to various countries around the world and how some do not allow the incorrect cords within a shipment while others do. Brazil, as far as I know, does not permit incorrect cordage. Argentina, Australia, and China (PRC) are all mutually exclusive. South Africa and India are mutually exclusive. Japan, Taiwan, and the United States are all mutually exclusive. If not prohibited, it is frequently cheaper to include multiple cords rather than create multiple regional SKUs when products are in low-volume production. That said, apparently the China market often likes to use US-style receptacles (types A or B), even though they use 220 V (😬). The US-style plug has better density (twice as many receptacles in the same space as the China receptacle (Type C, or I ?), and with the US receptacles, there are many more aftermarket cable options available. So I suppose that's my question: "Is this usage typical in China?" Of course, the big issue is that the US plug is not rated for the higher voltages, even though historically some people may say it works. I even fouind a website that shows this, https://www.travelchinaguide.com/essential/electricity.htm I believe it is critical for manufacturers to not condone the use of the US plug in this manner, which appears to be common practice. And I usually advise that this type of usage should never be described, recommended, or mentioned in any manuals, brochures, or other written material produced by a company, either externally or internally. If anyone is injured and an investigation reveals agreement with this usage, the company may be held liable.
