Mexico tightened freight Carta Porte on 13 January 2026 — every truck movement is an SAT compliance event.

Mexico's Complemento Carta Porte 3.1, the SAT's (federal tax authority) electronic waybill, has been the only accepted schema since 17 July 2024. A fresh ratchet landed on 13 January 2026: ~3,912 new customs combinations under c_NumPedimentoAduana, hazard codes aligned to IATA's 67th Edition (including UN 3551 for sodium-ion batteries), and IEPS (Mexico's federal excise) reset to 72.160500. Every commercial movement on a federal road now needs a CFDI (Mexico's e-invoice) that declares the SICT (transport-ministry) permit, the tractor plate, the RFC (taxpayer ID) of every owner and lessor, the driver's licence, product codes with weight and hazard flags, the civil-liability insurer, and origin and destination postal codes. Every field is cross-validated against catalogs that keep moving. Article 84-IV of the CFF (federal tax code) sets fines at $19,700–$112,650 MXN per infraction. An incorrect waybill makes the freight bill non-deducible. A missing one triggers presumption of smuggling, administrative embargo, and vehicle seizure at the next checkpoint. The carrier is jointly liable for what the shipper declared.

01The pain

Tuesday, 13 January 2026. A loaded tractor at a Querétaro bay, the driver's licence in the cab, the SICT permit on the door. The dispatcher asks the PAC (the SAT-licensed e-invoice stamper) to certify the waybill. It bounces. A customs key under c_NumPedimentoAduana that cleared the previous Friday no longer exists in the catalog the SAT pushed that morning. Until somebody downloads the new catalog and reloads the issuer, the truck does not move.

Carta Porte 3.1 has been the only legal waybill since 17 July 2024.⁴ The 13 January 2026 release added ~3,912 new customs combinations, aligned hazard codes to IATA's 67th Edition (UN 3551 covers sodium-ion batteries), and reset IEPS to 72.160500.³ EdifactMx is plain on the failure mode: a postal-code mismatch paralyses the unit, and a wrong waybill cannot be reissued without first cancelling the old one.² Fines under Article 84-IV of the CFF run $19,700–$112,650 MXN per infraction. Simetría Legal worked the example: a haulier with $10M MXN of annual freight loses the deduction outright. That is roughly a thirty-percent swing on the tax bill.¹

Then comes the criminal exposure. A missing waybill is presumption of smuggling: cargo embargo and vehicle seizure at the next federal checkpoint. Standard cargo policies exclude confiscation tied to tax non-compliance. The carrier is jointly liable for whatever the shipper declared.¹

$19,700–$112,650 MXN per shipment, under CFF Art. 84-IV.¹

02Who solves this today

Three Mexican-market vendors that publicly self-market on Carta Porte 3.1 issuance — PAC-grade tools whose product pages explicitly address waybill generation, SAT-catalog handling, and the per-shipment validation flow. Each entry verified live on the date of writing. Inclusion is not endorsement. The list is intentionally narrow.

Facture App — Complemento Carta Porte 3.1

Mexican CFDI issuer with a dedicated Carta Porte 3.1 page pitched at the version cut-over: "¡Cumple con el Complemento Carta Porte 3.1 Sin Costo Extra!" ("comply with no extra charge"). Path of least resistance for a small haulier or shipper already running CFDI 4.0 from the same account.

Facturador.com — Carta Porte 3.1 en el PAC

Mexican PAC and CFDI issuer with a Carta Porte page positioned as PAC-native: "Facturador.com ya cuenta con la versión actualizada del Complemento de Carta Porte". The route a haulier or shipper takes when they want CCP generation certified by the same PAC that already stamps their CFDI, without bouncing between issuer and stamper.

Listed providers publicly market to Mexican hauliers and shippers on the Carta Porte 3.1 / Complemento Carta Porte / CFDI 4.0 niche from their own product pages. Inclusion is not endorsement. Adjacent vendors were considered and excluded — Bind ERP's Carta Porte URL returned a bot-verification page with no visible product copy on the date of writing, FiscalPOP and Solución Factible homepages did not surface any verbatim Carta Porte self-marketing line, and Contpaqi / Facturama / Aspel-Siigo lacked an accessible Carta Porte landing page or returned 404 / redirect at published paths. All were dropped under the precedent that three verified entries beat a longer list with weak links. The Simetría Legal / EdifactMx / IDNube / Senhub citations above are operator-side trade-press and legal-advisory sources, not solution providers.
