Incorrect or Inactive Operator RFC
Fine: $17,020 - $97,330 MXN
The RFC of the operator (driver) must be active in the SAT and match exactly with their official identification.
Consequence
The SAT may consider the shipment as merchandise of illicit origin.
How to Avoid It:
- Validate the operator's RFC before each trip on the SAT portal
- Maintain an updated catalog of operators with verified RFC
- Use systems that automatically validate the RFC
Declared Weight vs. Actual Weight
Fine: $17,020 - $51,060 MXN
The weight of the merchandise on the Carta Porte must match the actual weight. Discrepancies greater than 10% generate problems.
Consequence
SAT audits and possible detentions of merchandise on the road.
How to Avoid It:
- Weigh the merchandise before generating the Carta Porte
- Include realistic tolerances in your processes
- Train shipping personnel on the importance of accurate weight
Locations with Incorrect Coordinates
Fine: $17,020 - $97,330 MXN
The GPS coordinates of origin and destination must correspond to the registered tax addresses.
Consequence
Inconsistencies between the declared route and the actual location of the facilities.
How to Avoid It:
- Use location catalogs with validated coordinates
- Verify that the coordinates correspond to the tax address
- Update locations when facilities change
Lack of Cargo Insurance Information
Fine: $17,020 - $51,060 MXN
The carrier's civil liability insurance is now mandatory and must be included in the Carta Porte.
Consequence
The Carta Porte is considered incomplete and not valid to cover the transfer.
How to Avoid It:
- Request a current policy from each carrier before assigning trips
- Verify that the policy covers the type of merchandise transported
- Keep track of expirations and renew on time
Expired or Incorrect SCT Permits
Fine: $17,020 - $97,330 MXN + vehicle retention
The federal motor transportation permit must be valid and correspond to the type of cargo transported.
Consequence
Vehicle stopped on the road and fines for both the carrier and the shipper.
How to Avoid It:
- Check SCT permissions before each assignment
- Maintain permit expiration calendar
- Do not accept units without a valid permit
Carta Porte 3.1 is mandatory in Mexico. Errors can generate fines of up to $97,330 MXN.
