Removing Regulatory Roadblocks
Expediting Market Access
> If a substance is listed in China’s Inventory of Hazardous Chemicals but has not been listed in the IECSC, does the substance need to be notified?
> Are manufacture or import activates of new chemical substances in Free Trade Zones subject to MEP Order 7?
> Copper Clad Laminate (CCL), is made of wood pulp paper or glass fabric, etc. (as reinforcing materials), immersed with resin, and clad with copper foil on single side or double sides under heating pressure. Prepreg is made of resin matrix, impregnated with continuous fiber or fabric under strictly controlled conditions. It will result in a composition of resin matrix and reinforcements, which is an intermediate material for producing composite material. The prepreg and CCL will be used for electronic substrate. Are they exempt from China NCSN as they are articles?
> A company intends to use the dihydrate of substance B as accessory for preparing products. The dihydrate of substance B is not listed in the IECSC, while substance B itself is an existing substance. Does the dihydrate need to be notified under China NCSN?
> Product A need to be added with stabilizer and chelating agent, neither of which is new chemical substance. However, they will react with product A and produce new chemical substance B. In this case, does substance B meet the exemption condition that “chemical substance which is produced from uninitiated chemical reactions during the final usage of other substances, mixtures or articles”, as specified in the Guidance Document?
> A biodegradable fiber A is used in improving oil production in oil field operation. It will be mixed with fracturing propping agent and other completion fluids and pumped to the underground, during which no chemical changes occur to the fiber. However, when it is sent to the predetermined position underground of well shut-in modes, it can rapidly degrade and dissolve in down hole temperature and becomes a partial acidic liquid without hazards. This partial acid liquid can react with calcium minerals in surroundings and get a liquid that is close to being neutral which is rich in calcium and magnesium. The liquid will flow back to the ground when the well resumes production. Will the fiber A be categorized into “Article” and exempt from China new chemical substance notification according to the use process description?
