Electronic products sold on the Amazon platform must meet specified standards. If they fail to comply, risks such as fire or explosion can easily occur, endangering consumers' lives and property. Therefore, many customers face issues like product removal or loss of selling rights due to the absence of UL reports. Malicious complaints from competitors can also trigger audits. All powered products listed on Amazon require relevant UL reports issued by ISO17025 accredited laboratories, preferably those recognized by Amazon's official labs, to ensure normal sales and link restoration.
All powered products listed on Amazon US require relevant ul test reports.
