Warm tips from CCRC

Annex XVII of reach regulation regulates a wide range of restricted substances, including polycyclic aromatic hydrocarbons, o-benzene, organotin, azo, nickel release, etc. CCK suggests that enterprises should first screen test items related to their own products, improve product risk awareness, actively respond to changes and updates of laws and regulations, and then determine the conformity of products through testing or supplier investigation, so as to ensure the smooth export of products to the EU market.
