On May 3, 2021, in the Diario Oficial, Mexico announced the entry into force date of June 1, 2021 for the requirement to have the Complemento Waybill for all mode of transportation. The Complemento Waybill supports the movement of goods within Mexico and provides temporary legal custody to carriers.
For the 120 calendar days following the enforcement date, the obligated parties issuing the Digital Tax Receipt Online or Electronic Invoice (CFDI) may do so without issuing the Complemento Waybill; however, at the end of this period, the issuance of the CFDI with the Complemento Waybill for all modes of transportation will be mandatory.
