However, two non-regulatory bodies, the International Agency for Research on Cancer (IARC) and the U.S. National Toxicology Program (NTP) Report on Carcinogens have issued styrene classifications related to carcinogenicity.

The Styrene Information & Research Center (SIRC) monitors the regulatory activity on styrene to ensure appropriate treatment and provide comments on rulemakings, when relevant. To review SIRC’s stance on current regulatory matters, please refer to SIRC’s statements in the Newsroom section of this website.
