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 have 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 ISO17025/ILAC ISO 17025 standard.

UL certification requires testing products and auditing factories, which are audited every quarter, which is expensive and time-consuming.

The UL test report is to issue a qualified test report after selecting the corresponding UL standard for the product to pass the test.
