As Amazon's strategic importance in global commerce continues to grow, foreign electronic devices are increasingly entering the US market through Amazon. On September 24, 2017, US authorities issued a law specifically targeting e-commerce, requiring Amazon to notify overseas e-commerce sellers on its platform to provide relevant safety compliance reports. Until a UL standard test report is submitted, Amazon must order the sellers to stop selling their products.

UL certification is a voluntary certification that requires product testing and factory inspections. Factories are inspected quarterly, and the process is costly, time-consuming, and strictly monitored.
A UL test report, on the other hand, is issued after the product passes the relevant UL standard tests.
