As of April 24, 2026, all fuel and diesel sales transactions must include a special complement in their electronic invoices (CFDI). This complement is called the Concept Complement for the Invoicing of Hydrocarbons and Petroleum Products.
What do I need to do?
-
Add the complement to your invoice. Every CFDI you issue for the sale of fuel must include the new Concept Complement for Hydrocarbons and Petroleum Products.
-
Use the correct product code In the ClaveProdServ field of your invoice, enter the code that corresponds to the fuel you are selling:
-
15101505 — Diesel
-
15101514 — Regular fuel (less than 91 octane)
-
15101515 — Premium fuel (91 octane or higher)
-
-
Update your invoicing system Make sure your invoicing provider or internal system is ready to issue CFDIs with this complement before the deadline.
What happens if I don’t comply?
Invoices issued without the complement or with an incorrect product code may be rejected by the SAT. This can create deductibility issues for both you and your clients.
Technical documentation available
The SAT has already published the technical files needed to implement this change (technical standard, XSD schemas, catalogs, and error matrices).
