II. Confidential Part

There are 3270 substances in the confidential section of IECSC (2013). They are shown in category names. No CAS numbers or molecular structures are given for those confidential substances. Companies have to submit a formal inquiry to the Solid Waste and Chemicals Management Center of MEE (MEE-SCC) to check whether a substance is listed in the confidential section of IECSC or not.
