There are different timeframes for USML shipment and Non-USML shipments. The timeframes vary by method of transportation. See below for both non-USML and USML shipments.

Note: Used self-propelled vehicles must be filed 72 hours prior to export. Shipments between the United Stated and Puerto Rico are exempt from the advanced filing timeframes highlighted in the FTR section 30.4(b)(3). However, the proof of filing, post-departure, AES downtime, exemption, or exclusion citation must be presented to the carrier prior to the arrival of goods at the port of unloading for shipments between the United States and Puerto Rico.
