Cannot ship certain products to certain states

Is there a way to restrict shipping certain products to certain states? We have a few items that we'd prefer not to ship to Hawaii or Alaska due to shipping cost as well as some items we're not allowed to ship to California (emissions control).  Only a few items can't be shipped so I don't want to restrict across the board. Some customers don't read the product info or hope that we'll notice and still ship.
Any suggestions?

Shipping Director can do it.

For example, you can put your restricted products in an unpublished category:

ErrorExit
"AK,HI".Contains(State) and Items.Any(Product.HasCategory("Shipping Restricted"))
"Sorry, we can’t ship restricted products to Alaska or Hawaii"

Thanks for the suggestion! I've heard a lot of talk about Shipping Director but wasn't sure what it was all about.
