The United States has very strict safety requirements. All electronic product manufacturers in the United States have required relevant safety testing many years ago. As Amazon’s strategic position in global commerce continues to increase, overseas electronic equipment continues to pour into the U.S. market through Amazon. The United States does not have mandatory safety inspections for overseas electronic product manufacturers. There have been a series of electronic product fires. In response to this situation, on September 24, 2017, relevant US departments issued laws specifically targeting e-commerce, requiring Amazon to notify overseas e-commerce companies selling on the Amazon platform to provide relevant safety measures. According to regulatory reports, Amazon must order merchants to stop sales before submitting a UL standard test report. And the test report must be a qualified report issued by a laboratory accredited by ISO17025/ILAC ISO 17025 standard.
UL certification requires product testing and factory audits, which are conducted every quarter. It is also expensive and takes a long time.
The UL test report is a qualified test report issued after the product has been tested according to the corresponding UL standards.

As long as the U.S. UL testing standards are not updated, they are valid for a long time.
