Regulations require a manufacturers to apply for China Compulsory Certification (CCC) from the nation's Certification and Accreditation Administration (CNCA). From 1 March, toy producers in China have been able to apply to three certification agencies nominated by the CNCA to certify their products. Toys are subject to inspection and certification review. Since 1 June 2007, no toy products without CCCs has been be allowed to leave factories, be sold or be imported into China. It is hoped this measure will mitigate the increasing international pressure on environmental protection, as well as further expand the nation's toy export market.
