I guess there is a move by the International Safety organizations to tighten up commercially sold electrical/electronic equipment.
Here is a link to the full report, excerpt below.
I wonder if China has a copy!!

KEY ELECTRONIC PRODUCT CONFORMANCE MARKS
ALL PRODUCTS MUST MEET VARIOUS REGULATORY COMPLIANCE requirements for safety, emissions, and other criteria before they can be sold globally. All industrial nations require specific marks on products before they can be sold there. Testing and certifying compliance are the keys to getting those marks. For electronic products, safety and electromagnetic compatibility (EMC) and electromagnetic interference (EMI) are key certification issues.
In the U.S., the Federal Communications Commission (FCC) dictates the testing requirements for EMC and EMI. Products can be Class A, marketed for commercial or industrial use and not intended for home use, or Class B, targeting home use. Class B requirements tend to be more strict than Class A requirements.
Stateside, the registered certification marks of Underwriters Laboratories (UL) mean that UL or a nationally recognized testing laboratory (NRTL) has tested and evaluated representative samples of the product and determined that it meets ULÍs specified product safety requirements(a). The negative impact of lacking a UL mark may be more de facto than de jure, but it's just about as crippling.
The Occupational Safety and Health Administration won't let products without the mark be used in businesses. Also, under the National Fire Code, electrical inspectors won't allow the product to be installed in buildings. You may be obligated contractually to have a UL mark on your product, or some customers might not sell it. And, savvy consumers look for the UL mark on products they buy.
In Europe, all products must have a CE or “Conformite Europeenne” mark (b). The CE mark is all-inclusive. It shows that the product complies with the “essential requirements” of European laws or directives. It also indicates the product's conformance to legal requirements with respect to safety, health, the environment, and consumer protection in the European Union.
The CE marking is mandatory for certain product groups, but it can be achieved either by using an external test house like an NRTL in the U.S. or by a company's internal self-certification process. More information is available from the U.S. Department of Commerce at Export.gov - CE Mark.
