In addition, the permitted usage applications of the four new toxic substances (Listed No. 174, Serial No. 01-04) have been specified and only allow these substances for R&D purposes and the manufacture of EPS and XPS. Starting from 1 Jan 2016, chromated copper arsenate (Listed No. 055, Serial No. 25) will be prohibited to be manufactured, imported, sold or used in wood preservative. For PBDEs (Listed No. 091, Serial No. 02-08), prohibitions will be imposed on the manufacture of flame retardants for electronic products on 1 Jan 2016. Permits already obtained for these substances will be valid until the expiration date.
