I've actually heard from some back a few months ago when LOC had initially been patched, that items were in fact tagged as well. The method of cloning used duplicated the card/item's serial, and Applibot supposedly found a way to distinguish these copies, ban the cookers, and plug the exploits being used.

Now it seems the cloners are back and stronger than ever. I don't know for sure how Applibot's tagging system works, but the fact that cards can be cloned suggests that an ID system isn't a deterrent anymore, meaning that it may be irrelevant whether potions are tagged or not. The only reason cards aren't cloned more often is likely because it works to their disadvantage.
