I did read that a US survey team on the ground after the attack in 1988 concluded that the type of biological/chemical weapons used were of Iranian origin. It's not something easily found with Google though.

"Iran overran the village and its small Iraqi garrison on 15 March 1988. The gassing took place on 16 March and onwards; who is then responsible for the deaths - Iran or Iraq - and how large was the death toll knowing the Iranian army was in Halabja but never reported any deaths by chemicals?

The best evidence to answer this is a 1990 report by the Strategic Studies Institute of the US Army War College. It concluded that Iran, not Iraq, was the culprit in Halabja."
