Al Jazeera - The reimposition of US sanctions on Iranian oil exports is threatening various parts of Iranian society.

But the saffron-exporting sector believes it is virtually sanction-proof and some think the sanctions may have even been good for business.

At a conference of industry experts hosted by the University of Torbat Heydarieh, one saffron trader argued, "We're the main producer and exporter of saffron in the world, there's no alternative ... By legal or illegal means, we're certain our products will be exported."
