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 required relevant safety inspections many years ago. With the continuous improvement of Amazon's strategic position in global commerce, electronic equipment from abroad has continuously flooded into the US market through Amazon. The United States does not have mandatory safety inspections for overseas electronic product manufacturers. There have been a series of fire incidents in electronic products before. In response to this situation, on September 24, 2017, relevant departments in the United States issued a law specifically for e-commerce, requiring Amazon to be obliged to notify overseas e-commerce vendors selling on the Amazon platform to provide relevant security. 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 ISO17025/ILACISO17025 standard.
UL certification requires testing products and auditing factories, which are audited every quarter, which costs a long time.
The L test report is a qualified test report issued after the product is selected according to the corresponding UL standard and passed the test.
