Qualified Products List

Due to the administrative restructuring of the Pacific Northwest Snowfighters (PNS) organization, Clear Roads has assumed responsibility of the Qualified Products List for dieicing products. The product testing and administration of the QPL will remain essentially the same with a few process improvements.


The mission of the Clear Roads QPL is to “strive to serve the traveling public by evaluating and establishing specifications for products used in winter maintenance that emphasize safety, environmental preservation, infrastructure protection, cost-effectiveness and performance.”

Guidance for Vendors

To begin the process of getting your product approved and listed on the QPL, please complete the Product Submission Form. Test results from a third-party lab are necessary prior to completing the form. Submitted paperwork will be reviewed and if test results are within specifications, Clear Roads will ask for product samples. The Guidance Document for Material Qualified Products List, Specifications, Test Methods, and Product Purchasing (see Document section to the right) has additional information about the process, qualifications, and how to send your product.
