iPIC is a voluntary and informal mechanism of information exchange on intended trade between countries in ozone depleting substances (ODS) and hydrofluorocarbons (HFCs), mixtures containing these as well as products and equipment. It enables countries to share details of eligible importers and exporters with other member countries through a secure online platform. iPIC has become a global voluntary initiative used by more than 100 like-minded states who wish to strengthen the implementation of their national licensing system for ODS and HFCs.
