The follow-up management of registered new chemicals plays an essential role in ensuring the overall implementation of new chemical management under MEE Order No. 12. Enterprises handling new chemicals assume primary responsibilities in this regard. They are obligated to fulfill certain post-registration obligations in accordance with MEE Order No. 12 and the Transitional Arrangements for Environmental Registration of New Chemical Substances (a.k.a. Transitional Arrangements). Table 1 below summarizes the major post-registration obligations, application scope, and to whom they apply.
