As Cancun is in Mexico, yes, it's an international flight. I suspect your real question is whether Cancun has preclearance where you go through US immigration/customs at the point of origin. Cancun does not have that (nor does any airport in Mexico). You do indeed have to clear immigration, collect your bags, and clear customs in Houston, then recheck your bags to Nashville.
