If you're looking to Download F3DX Carta Porte on your Chromebook laptop Then read the following guideline.

As of January 1, 2023, Mexican authorities require all transportation carriers—including FedEx—to collect and provide additional details about each package they intend to transport. This applies to packages shipped to, from, and within Mexico, across all modes of transportation. This extra information is called a Complemento Carta Porte (Carta Porte for short, or waybill supplement in English). This app helps users provide the information requested in the domestic waybill in addition to the information requested through the several applications FedEx has made available. The additional information must comply with the SAT’s requirements, and it has to be consistent with the pertinent catalogues the Tax Authority has published for that purpose. This app helps all customers hiring FedEx services, whether they are frequent/occasional customers, or individuals/legal entities with or without a FedEx account, must provide the requested information using FedEx open API. Otherwise, FedEx may not be able to accept their packages for carriage.
