It's more about what you *can't* bring back.  

The following items are legal in Mexico and readily available everywhere in the border area, but cannot be brought into the United States: Cuban cigars, turtle products, switchblades, butterfly knives and fireworks. For full customs information, check the U.S. Customs web site. http://www.customs.ustreas.gov
