I don't know about other people, but we had to go here after we got our quarantine stamps to EXIT the country. So if they tell you that you need to go to "Cuatros Altos" or "France Field", here it is. You should have three copies each of your passport, TIP, DIJ letter, vehicle title, and Panama import permit. After this you can go to the port for inspection.
