About UL

Empowering Trust
UL helps create a better world by applying science to solve safety, security and sustainability challenges. We empower trust by enabling the safe adoption of innovative new products and technologies. Everyone at UL shares a passion to make the world a safer place. All of our work, from independent research and standards development, to testing and certification, to providing analytical and digital solutions, helps improve global well-being. Businesses, industries, governments, regulatory authorities and the public put their trust in us so they can make smarter decisions. 

Our offerings are designed to reduce testing complexity and manage risk
UL’s comprehensive testing, certification, assessment and regulatory compliance services are designed to foster innovation, enhance product and process quality, enable safety and, most importantly, help you meet your business goals.

Our broad capabilities enable us to help you address a wide variety of key business needs that may arise throughout your product development life cycle and deployment phase. Working with one provider allows you to take advantage of our cost- and time-saving service bundles, and our integrated testing and certification plans allow you to achieve your go-to-market plans in a timely manner.

Our technical experts can also help you align your products to the appropriate UL Certification category and applicable standards. This enables manufacturers of UL Certified products to easily source components that demonstrably meet their compliance needs and project specifications.


UL tests and certifies standardized, engineering and high performance polymeric materials for compliance to global standards intended to mitigate the risks of fire, electric shock, personal injury and environmental hazards.

Gaskets & Seals
UL’s certification program evaluates non-metallic gasket and seal materials such as elastomers, composite gasket material, flexible cellular material, thermoplastics and thermoplastic elastomers for use as components and parts of end products.

UL’s certification program covers the evaluation of organic and metallic corrosion protection coatings of steel enclosures. UL might conduct a salt-spray (fog) test, moist carbon dioxide-sulfur dioxide-air test, and/or a light and water test for clear coatings, among other tests.

Marking & Labeling
UL tests and certifies marking and labeling systems and materials for adherence to established performance requirements. Typical evaluations include comprehensive testing for permanency—such as curling, wrinkling, shrinkage or loss of adhesion.

Electrical Insulations Systems (EIS)
An electrical insulation system (EIS) is any uniquely specified combination of two or more insulating materials used in electrical equipment. Materials can be evaluated individually (EIM; electrical insulation materials) but are often evaluated as a complete EIS.

With our OEM approvals in the automotive industry backed by technical expertise, we support you along the entire product development and automotive supply chain: From the planning and design phase, to material selection and the final Production Part Approval Process (PPAP), for an optimized time to market.

Electrical & Electronic
Materials and end-product manufacturers find solutions in UL’s services portfolio that lead to high-performance products. Working with both sides of the industry, UL also helps match optimal materials to the right end-products.

The UL Recognition Mark
Your customers want to know one thing: your products are safe. That’s why our UL Recognition Mark is so important. It says a plastics material has been tested not just against minimum standards of safety, but against the highest standards in the industry: UL Standards.

Our expertise of the plastics industry enables us to help you ensure that your standardized, engineering and high-performance polymeric materials comply with global standards. Our tests and certifications aim to mitigate the risks of fire, electric shock, personal injury and environmental hazards. We work with companies involved in compounding, extrusion and injection molding as well as raw material producers and automotive manufacturers and their suppliers
