Methyl methacrylate (MMA) under IECSC

C5H8O2 · 甲基丙烯酸甲酯

Status: Listed. MMA is on the IECSC public portion. New-substance notification under MEE Decree No. 7 (2010) is NOT required. **MMA IS on China's Catalog of Hazardous Chemicals** (Flam. Liq. 2 plus Skin Sens. 1 classification). Hazardous Chemicals Operation Permit IS required for production / storage / distribution. NOT on Highly Toxic Chemicals Catalog. NOT on Easily-Made Drugs Catalog. **0% China VAT export rebate** for MMA (HS 291614) reflects Beijing aromatic-petrochemical export-discouragement signal (similar to acrylic acid batch 39 plus acetone batch 15 pattern). China dominates global MMA capacity (verify percent-of-global share against ICIS or S&P Commodity Insights before quoting; prior industry reports cited approximately 35 percent at ~2.5 to 3 Mt/yr) led by Hengyi Petrochemical, Sinopec, Sumitomo Chemical Shanghai, Mitsubishi Chemical Performance Polymers China, LG MMA China.

MMA is comfortably IECSC-listed but IS on Catalog of Hazardous Chemicals (Hazardous Chemicals Operation Permit chain required). NOT on Highly Toxic Chemicals Catalog. NOT on Easily-Made Drugs Catalog. **0% China VAT export rebate**. China dominates global MMA capacity led by Hengyi Petrochemical, Sinopec, Sumitomo Chemical Shanghai, Mitsubishi Chemical Performance Polymers China, LG MMA China. Production: ACH (~50 percent) plus C4 oxidation (~25 percent) plus BAMM ethylene Lurgi (~25 percent and growing).
