It hasn't been made legal.
Trafficking in human organs is illegal in the US and much of Europe. There are some places where it is allowed.
The actual situation is a little more complicated than that, but basically, yes, the US does not allow trafficking in ivory. (There are some exceptions for antiquities and the like.)
Ideally? It has slowed illegal immigration and drug trafficking from Mexico into the US. In reality? Nothing. Many illegal aliens no longer try to enter the United States as it is in the middle of an economic recession, and the drug trafficking into the US has continued unabated, even spilling some of the Mexican War on Drugs violence into Arizona, New Mexico and some counties of Texas.
Felony.
