Hand Warmer Amazon UL499 Compliance Certification

Why is the UL Test Report necessary for Hand Warmers on Amazon?

What is UL499 Certification?

UL499 Certification is a safety standard established by UL (Underwriters Laboratories) in the United States for hand warmers. It is aimed at ensuring consumer safety through compliance with safety regulations, especially for products sold on Amazon. Amazon requires hand warmers and related products to have a UL499 report in order to continue selling them. Unlike domestic e-commerce platforms, which require testing reports to be submitted before listing products, Amazon requests the UL499 report after listing the product. If this report is not provided, popular products could be suddenly delisted, resulting in significant losses for many businesses. Therefore, it is essential to obtain the UL499 certification in advance to avoid having your product listing removed.

What is the difference between a UL Test Report and UL certification?

- UL Certification: This is a voluntary certification that involves product testing and factory audits. The audit is conducted quarterly, and it requires high fees, long processing times, and strict factory inspections.

- UL Test Report: This is a test report issued after a product is tested according to the relevant UL standards. It is more affordable, has a shorter processing time, and does not require a factory audit. However, it is only valid for use on Amazon and cannot be used for customs clearance.

Why is a UL Test Report required?

For any powered product listed on Amazon, a UL report is required. The test report must be issued by a laboratory accredited with ISO 17025 to ensure that the product can be legally sold and its link reinstated if removed. Amazon sellers typically receive a review email like this one (this particular email pertains to power bank sellers; different products have different standards).
