Some brands do. Morton's kosher salt contains sodium ferrocyanide to
prevent caking.

Kosher salt is crushed into little flakes, so it measures different than
table salt (it's fluffier, therefore it is less dense and you get less
salt per volumetric measure.) Other than that, it is no different than
non-iodized table salt. (and there is no reason it couldn't be iodized,
it just isn't)
