Re: CorMedix Inc. (CIK: 0001410098) Form S-3 Filed on September 30, 2025 File No. 333-290636 

Pursuant to Rule 477 under the Securities Act of 1933, as amended, CorMedix Inc. (the “Registrant”) hereby requests the withdrawal, effective immediately, of Registration Statement on Form S-3, File No. 333-290636 (the “Registration Statement”), which was originally filed by the Registrant with the Securities and Exchange Commission (the “Commission”) on September 30, 2025. The Registration Statement was mistakenly filed on EDGAR with an “S-3” tag, when the filing should have tagged the Registration Statement as an “S-3ASR.” The Registration Statement will be refiled on EDGAR promptly, with the correct “S-3ASR” tag.

The Company confirms that no securities have been sold under the Registration Statement and that the Registration Statement has not been declared effective by the Commission. The Company understands that, pursuant to Rule 477(b) under the Securities Act, this application for withdrawal will be effective at the time filed with the Commission unless, within fifteen calendar days after the filing, the Commission notifies the Company that the application for withdrawal will not be granted.

Please direct any questions or comments regarding this correspondence to Andrew Marmer of Willkie Farr & Gallagher, LLP, at (212) 728-8847. Thank you for your assistance in this matter.
