Listing Services


A2LA72dpiTEi-Listing Services is a Product Certification Body, accredited to the requirements of ISO/IEC 17065 by the American Association for Laboratory Accreditation (A2LA, cert #2946.01), and accepted by the Recreational Vehicle Industry Association (RVIA) as a third-party listing agency. We specialize in listing Recreational Vehicle components, and we’re accredited to certify compliance with many standards published by ASME, ASTM, CSA, IAPMO, NSF, and UL, among others. We can list many other different kinds of products to standards not in our scope of accreditation, as long as your governing body does not require listing by an accredited certification body.

Why Get Listed?

In the public interest, some industries and government bodies require certain products to meet standards of safety and quality.  These standards are written and made publicly available by reputable organizations.  Your product is not allowed to be sold in the marketplace unless it meets the specified standards, and has been proven to do so by an independent third party.

Once we have certified that your product meets all the necessary requirements, we add it to our list of certified products; thus, your product is said to be listed.  You are also granted a license to use our certification mark on your product, as a demonstration that you have received third-party certification and listing.  Having this mark adds value to your product, because your customers will know that it has been independently tested and they can have confidence in its quality.

How To Get Listed

checklistDownload, fill out, and return the Listing Application. Please be as thorough as possible. We’ll need a set of technical documentation for each product you want listed. That includes things like drawings, bills of materials, etc. The more information we have, the less time it will take to evaluate your product. You then submit the completed form and documentation to us, and we’ll get started!

Once we’ve received your complete application and supporting documentation, we’ll begin our evaluation. Our Listing Compliance Engineer will review your paperwork and make sure everything is present and in order.  He will contact you if he needs any additional data.  He will arrange for the necessary product testing and facility inspections to be completed.

Once everything has been completed, we will send you an Evaluation Report describing the results of the evaluation, and describe any deficiencies you need to address before receiving certification.  Once any concerns are resolved, your application will be presented to the Listing Review Committee.  Once they grant your certification, we’ll send you an official Listing Sheet, documenting that you have been certified and listed by TEi-LS. Congratulations!

After You’re Listed

Once you’re listed with TEi-LS, you have a license to use our certification mark on your listed products, as long as you continue to meet the requirements for listing and pay your invoices on time. We’ll do follow-up inspections and selected testing every year to verify your ongoing good standing.

If you want to make changes to your listing (add new products, change a product’s design, or change suppliers), we need to approve and document the change. Just complete a Listing Amendment Application, and we’ll handle that for you right away.
