▍What is WERCSmart REGISTRATION?

WERCSmart is the abbreviation of World Environmental Regulatory Compliance Standard.

In the processes of selling, transporting, storing and disposing products among retailers and registered recipients, products will face increasingly complicated challenges from federal, states or local regulation.

From the JIS standard website, we noticed that JIS C 62133-2 “Safety requirements for portable sealed secondary cells, and for batteries made from them, for use in portable applications-Part 2: Lithium systems” was released on Dec. 21st 2020. This standard was established according to not only IEC 62133-2 2017, but also the Attached 9-Lithium Battery in the Electrical Appliance and Material Safety Law ”DENAN”, especially the testing items which are mainly from the content of DENAN Attached 9.
The mainly technical differences between JIS C 62133-2 and IEC 62133-2 are shown below:
Consumer Product Safety Commission (CPSC) is a U.S. government agency that protects the American
public from products that may present safety hazards. This independent regulatory body focuses on
consumer items that pose an unreasonable risk of fire, chemical exposure, electrical malfunction, or
mechanical failure. Products that expose children to danger and injury are a particularly high priority for
the CSPC. In addition to investigating complaints from consumers concerning unsafe products, this
group also issues recalls of products that may be defective or that violate mandatory standards.
