According to the PriceWatch, the South Korean MMA (Methyl Methacrylate) market with 99.9% purity experienced a 4.4% decline in prices during Q2 2025. The average FOB Busan price for the quarter was recorded at USD 1451 per metric ton.
This methyl methacrylate price trend correction was primarily driven by persistent weakness in regional demand, excess market supply and heightened geopolitical uncertainties including the expiration of the U.S. administration’s 90-day tariff reprieve, escalating tensions between the U.S. and Iran, and new U.S.-China tariff measures.

Despite a steady rise in upstream feedstock prices such as naphtha, acetone, and MTBE, producers were unable to pass on costs as buyers reduced offtake volumes, citing economic caution and expectations of further declines. In China, the ramp-up of new MMA capacities added further pressure to the regional supply landscape, while downstream demand from sectors like PMMA and cast sheets remained lacklustre.
Additionally, currency fluctuations and cautious inventory strategies from buyers limited procurement activity. Given the ongoing supply overhang and muted derivative demand this soft trend is expected to continue in the near term with prices likely to remain under pressure barring a significant rebound in demand or resolution of trade-related tensions.
