Despacho Previo Changes

Despacho Previo was implemented in the early 1990’s to alleviate congestion at the border and to comply with Mexican Customs law requiring documentation and payment of duties prior to the railcar entering Mexico. The rules, as spelled out in BNSF Rules book 6100-A, Item 3140E, govern the amount of time that is allowed for a car to be documented for entry into Mexico. If the free time allowed is exceeded, the tariff specifies the amount of document delay charge that is owed.

Although the vast majority of Mexico traffic is documented prior to arrival at the border, to achieve velocity and throughput improvements on Mexico traffic, it is critical that all traffic be documented in a timely manner.

Changes to Late Documentation Charges
and a New Charge for Undocumented Railcars

On December 11, 2006, the penalty for late documentation will increase to $75 per car, per day, or fraction thereof for the first three days, subsequent to the free time. Thereafter, the document delay charge will be $150 per car, per day.

In addition, on January 1, 2007, a new charge will be assessed for undocumented railcars that are located within 50 miles of the border provided the free time allowed has been exceeded. The charge will be $500 per railcar. This charge is in addition to any document delay charges and must be paid at the time of release along with any document delay charges due.
