Mexico’s Tax Administration Service (SAT) has announced an update to the CFDI 4.0 catalogs, a relevant change for companies managing tax operations—especially those involved in foreign trade processes.

What changed in the CFDI 4.0 catalogs?

The update focuses on the following catalog:

c_NumPedimentoAduana

This catalog is related to customs declaration (pedimento) codes, which are essential for the correct issuance of tax invoices in import and export operations.

Key changes:

  • 12 new records have been added to the catalog
  • No changes to the XSD schemas, meaning the technical structure remains the same
  • Updates are focused on customs broker licenses and valid combinations

New records added

Below are the newly incorporated values:

When do these changes take effect?

These new records will be valid starting on:

April 24, 2026

How does this impact your business?

Although the update does not modify the technical structure of CFDI, it may affect:

  • Tax invoice validation processes
  • Integration with ERP systems such as Microsoft Dynamics 365 Business Central
  • Electronic invoicing processes linked to foreign trade
  • Tax compliance with SAT

If your system is not updated with these new values, you may face stamping errors or CFDI rejections.

Key recommendation

  • Keeps catalogs automatically updated
  • Allows quick adaptation to SAT changes
  • Prevents manual rework and compliance risks
