On February 1, 2021, TDI transitioned to a paperless product submittal process.
TDI continues to review product submittals in the order they are received.
Submit Product Evaluation Requests via Email
Use the following guideline to prepare your submittal:
Your submittal must be complete and include all required documents in one email. TDI will accept only one submittal per email. Send your submittal requests to:
ProductEvaluationSubmittals@tdi.texas.gov
In the subject line of your email, please indicate the product type, whether it is impact or non-impact resistant, and if it is a request for a new product listing or an update to an existing evaluation report by including the product evaluation report number. As an example, for new product evaluation reports: Casement Wood Windows, Impact, New Evaluation; or, for an update to an existing product evaluation report: Casement Wood Windows, Impact, WIN-"xxx".
