Removing Regulatory Roadblocks
Expediting Market Access
> Is it required to submit a GPC (Gel Permeation Chromatography) report for polymer Simplified Notification?
> In the notification of polymers, companies are required to provide the information of additives. Then how detailed the information on additives should be? Does it include CAS number, substance name, concentration, feed ratio and information of whether listed on IECSC, etc.?
> One Chinese domestic company W produces and also imports certain polymer formed by substance A and B, C and D. The non-Chinese exporter Y uses A, B, C and D as initial reactants in his production (all four substances are added into the reaction container). Due to reasons of process confidentiality, Company Y exports the polymer AB formed by A and B to Company W who further adds C and D in the polymer production (C, D and polymer AB are added to the reaction container). So when W applies for the special case of simplified notification, which monomers should he fill up in the application form, four substances (A, B, C and D) or three substances (C, D and polymer AB)?
> In the simplified notification for polymers, if feed ratios of all the monomers vary and produce several polymers with distinct molecular weight yet of the same chemical name, is it acceptable to notify all these polymers as one new chemical substance?
Company A and B are both foreign companies. Company A has obtained the registration certificate of the new chemical substance P. Company A will sell substance P to company B, and B will re-sell it to company C. Does company C need to obtain the registration certificate?
We have a product reagent in small bottles wrapped by outer boxes. How should we label it in this case?
How to determine the hazard classification of mixtures?
What chemicals need to be registered?
If the new chemical substances has already been notified under SEPA Order 17 (predecessor of MEP Order 7), is it necessary to comply with the scientific research record notification under MEP Order 7?
