For tracking purposes, each pro-forma should include the name of your production and/or production entity. It must also have a Shipping Manifest Number. The shipping manifest number, along with the pedimento number will be what identifies each shipment coming in and going out of México; and these I.D. numbers will be kept in your files, your brokers’ files and in Custom’s files (and computers).
You can devise your own system to use as a shipping manifest number, but one that has proved to be the successful is an eight digit number, followed by a two or three letter department code.
An example would be: 05-09-27-01-PD
05 = the year
09 = the month
27 = the day
01 = first shipment for that day
PD = Production Department (department code)
Suggested department codes are:
