Overview
UL Standards & Publications is a program focused on creating safety, security, and sustainability standards for products and services. Founded in 1894, Underwriters Laboratories (UL) started with a focus on promoting safe living. Over the years, UL has developed over 1,500 standards, impacting a wide range of industries from electrical appliances to cybersecurity. UL certification is highly recognized; it ensures products meet safety regulations. The organization collaborates with non-profits, government bodies, and private companies like Whirlpool and General Electric. Statistics show that UL has accredited over 22 billion products worldwide. The non-profit division, UL Research Institutes, continues to conduct studies to improve global safety standards.
Requirements & Verification
Evidence Requirements
Manufacturers must submit product samples and technical documentation for laboratory testing against the applicable UL standard. Testing is conducted by UL Solutions' accredited laboratories, and products must demonstrate compliance with all relevant safety requirements. Follow-up inspections (Follow-Up Services) are conducted at manufacturing facilities to ensure ongoing production consistency with certified samples.
Prerequisites
Assessment Process
Products undergo laboratory testing by UL Solutions' accredited engineers against the applicable UL standard. Testing involves physical, electrical, mechanical, and/or environmental performance evaluations on submitted product samples. Upon passing, manufacturing facilities are enrolled in UL's Follow-Up Services program, which includes periodic unannounced factory inspections to verify ongoing production compliance. Any product modifications trigger re-evaluation.
Renewal & Compliance
UL certification is maintained through UL's Follow-Up Services program, which involves periodic unannounced factory inspections to verify that production continues to meet the certified specifications. Any changes to product design, materials, or manufacturing processes must be reported to UL and may require re-evaluation. Annual fees apply for continued use of the UL Mark.

Consider Alternatives If...
If your product is primarily sold in markets outside North America where other marks (e.g., CE, TÜV) carry more regulatory weight, UL certification alone may not be sufficient. Companies with very limited budgets may find the testing and certification fees significant, particularly for complex or multi-component products.
