Sending a car to Tunis

Your husband has definitely the right  to import a car (may be two) if he traveled with his Tunisian passport and spent at least 2 years abroad. A complicated, but sure administrative procedure should be done. The car must be touristic (private, familial/not commercial). But he also has the right to import a truck if he establishes any kind of company (not difficult). You as well might be eligible to bring a car as a foreigner legally resident in Tunisia if you fit some other conditions.
I advise you to visit the web site of the Tunisian Customs, but unfortunately the English section is still under construction. I assume your husband speaks French and Arabic

Thank you so much for the helpful info. One other question the cars must be no more than three years old?

Thanks again
