1. What is UL499 certification?

UL499 certification is the UL safety test standard formulated by the United States for hand warmers, and it is also a safety inspection performed to protect the safety of consumers. Especially on the Amazon platform, it is required that related products such as hand warmers must apply for UL499 reports before they can continue to be sold. , Unlike domestic e-commerce, domestic e-commerce must first provide a test report before entering the platform, while Amazon will ask you to provide a UL report after it has settled in, otherwise the popular products sold will be suddenly removed from the shelves. For enterprises, it is undoubtedly the biggest loss, so be sure to apply for UL499 certification in advance, otherwise the link will be deleted directly from the shelves.

2. What is the difference between UL test report and UL certification?

UL certification is a voluntary certification, which requires testing products and auditing factories, and auditing once a quarter. The cost is high, the time is long, and the auditing of factories is very strict.

The UL test report is to issue a qualified test report after selecting the corresponding UL standard for the product to pass the test. Low cost, short cycle, no need to audit the factory. Can only be used on Amazon, customs clearance is invalid.

3. Why do UL test report

The electronic products sold on the Amazon platform must meet the specified standards. If they are not qualified, it is easy to cause fire, etc., which will endanger the safety of consumers' lives and properties. Therefore, many customers have been removed from the shelves due to the lack of UL reports, and their sales rights have been removed. In addition to other problems, malicious reports among peers are also indispensable to trigger audits.

For live products to be listed on Amazon, relevant UL reports are required, and test reports issued by ISO 17025-qualified laboratories are required for normal sales and restoration of links.
