1. What is the difference between UL test report and UL certification?
The United States is a country with very strict safety requirements. All electronic product manufacturers in the United States have required relevant safety inspections many years ago. With the continuous improvement of Amazon's strategic position in global commerce, overseas electronic devices continue to flow into the US market through Amazon, and the US does not have mandatory safety inspections for overseas electronic product manufacturers. A series of electronic product fire incidents occurred before. In response to this situation, on September 24, 2017, the relevant US departments issued a law specifically for e-commerce, requiring Amazon to be obliged to notify overseas e-commerce sellers selling on the Amazon platform to provide relevant safety measures. Before submitting the UL standard test report, Amazon must order the merchant to stop selling. And it is required that the test report must be a qualified report issued by a laboratory accredited by the /ILAC ISO 17025 standard.

What is the most serious consequence of failing to make a UL standard test report for electrical and electronic equipment?
The most serious consequence of not reporting North American safety regulations for electronic equipment is not being blocked by Amazon, but being targeted by competitors under the premise that the merchant is selling well. safety report,
Competitors will entrust U.S. lawyers to send letters to Amazon to stop selling the company's products and apply for court proceedings to destroy all of the company's products on Amazon. Not only did merchants lose all their inventory at this point, but they also had to pay attorneys’ letters and destroy the product, which could mean the company was essentially driven out of the North American market.
