Baled hay would probably mimic baled/bundled fibers just as you said, potential for deep seated fire, smoldering, etc.
Baled natural fiber rags are Class III so being a natural material that could absorb water it looks like Class III is probably closer to a realistic classification. Craig L.

I'm not sure it would burn like a standard class III. You could have the potential for a deep seated fire that sprinklers might not be able to easily contain. To fully extinguish a fire, you would probably have to remove the burning (or more likely smoldering) bales from the building, break them apart and wet them down. In that way, it may behave more like a commodity such as piled wood chips. Anybody with first-hand hay fire experience out there?
