According to Claight market monitoring, domestic formaldehyde plants underwent maintenance shutdowns in early September 2026, leading to lower inventory levels. Claight market monitoring shows that the price of raw material methanol rose, driving a cost-driven surge in the domestic formaldehyde market.
ECHEMI reported on September 24, 2026 that downstream plate factories engaged in pre-holiday inventory replenishment, providing support for a strong formaldehyde market finish. The combination of reduced inventories after the maintenance shutdowns, higher methanol costs and buying from plate factories ahead of the holiday period accompanied the month's rise of 27.8% to USD 261.42/tonne.
