Yes small world indeed (croc world) 
The problem is not with CITES regulations but rather with USFWS and the ESA regulations which are backwards to CITES.
You should be able to get Osteo's from africa to Mexico as long as they are CITES I/D (which is same as CITES II) .... good luck finding a legit seller over there though as 99.9% are fake scammers!
