Wanhua Chemical will start a 60-day maintenance shutdown on October 10, 2026, at its 1.20 million-ton annual-capacity phase II ethylene unit in Yantai. Wanhua Chemical stock was last at CNY 70.20 on the Shanghai Stock Exchange, 27.63 percent below its CNY 97.00 52-week high.

Maintenance starts with phase II

According to Futubull on October 8, 2026, the phase II unit will halt for scheduled maintenance from October 10 for 60 days. The phase I unit will continue operating, and the notice described the work as part of the annual maintenance plan.

The production detail matters because the shutdown affects a 1.20 million-ton ethylene unit rather than the entire Yantai complex. That leaves the company's first phase running while management carries out the planned overhaul.

What changed in the first half?

According to Stockstar on August 26, 2026, first-half revenue reached CNY 119.32 billion, up 31.26 percent from the prior-year period. Net profit attributable to shareholders rose 64.35 percent to CNY 10.06 billion.

The earnings mix also shifted. According to 10jqka on September 9, 2026, petrochemicals generated CNY 47.74 billion of first-half revenue, up 36.65 percent, while fine chemicals and new materials reached CNY 22.55 billion, up 44.28 percent. Polyurethane revenue increased 21.87 percent to CNY 44.96 billion.

Three dated operating signals

On August 18, 2026, Wanhua subsidiary BorsodChem announced increases of EUR 200.00 per ton for MDI, EUR 350.00 per ton for TDI and EUR 300.00 per ton for polyols, as reported by 10jqka on September 9, 2026. On September 9, 2026, the company reported CNY 119.32 billion of first-half revenue and CNY 10.06 billion of net profit. On October 8, 2026, the company announced the 1.20 million-ton ethylene maintenance shutdown.

Next scheduled company date

The next substantiated operating date is October 10, 2026, when the phase II ethylene unit begins its planned maintenance. The 60-day schedule makes production continuity at phase I the key near-term operating detail.

Stock remains below yearly high

Wanhua Chemical was last at CNY 70.20 on the Shanghai Stock Exchange on October 9, 2026 at 3:00 p.m. CST. Its market capitalization was CNY 219.8 billion, while the 52-week range stood at CNY 60.60 to CNY 97.00.
