Wanhua Chemical (ISIN CNE0000016J9) plans a 60-day shutdown of its 1.20 million-tonne-per-year Phase II ethylene plant from October 10, 2026, according to Sina Finance on October 8, 2026. The company said the annual planned maintenance should not have a material impact on operations, while the Phase I ethylene plant will continue operating.

Ethylene maintenance starts October 10

The shutdown gives the maintenance plan a defined 60-day duration and separates the affected Phase II unit from the continuing Phase I operation. For investors, the key issue is therefore the effect on production volumes and margins rather than a permanent capacity change.

The maintenance notice follows a strong first-half operating picture. According to Futubull, Wanhua Chemical reported first-half 2026 revenue of CNY 119.316 billion, up 31.26 percent year over year, and net profit attributable to shareholders of CNY 10.063 billion, up 64.35 percent.

Profit growth sets the operating context

The second quarter supplied the sharper comparison. Revenue reached CNY 65.264 billion, up 36.44 percent year over year and 20.74 percent from the first quarter, while net profit rose 108.68 percent year over year to CNY 6.345 billion, according to the same interim-report analysis.

The figures show why the maintenance period matters for the next operating update: Wanhua enters the shutdown with strong year-over-year growth, but a planned production pause can alter quarterly volume and cost comparisons. The company operates across polyurethanes, petrochemicals, fine chemicals and new materials, according to its investor-relations information.

Market value and Shanghai range

Wanhua Chemical had a market capitalization of CNY 218.5 billion on October 8, 2026. Its 52-week range was CNY 60.60 to CNY 97.00, placing the market value against a wide trading history for the Shanghai-listed shares.

The company's investor-relations page identifies Wanhua Chemical Group Co., Ltd. as listed on the Shanghai Stock Exchange under ticker 600309, with the listing dating to January 5, 2001. The next material operating marker is the planned October 10 start of the ethylene maintenance program and its scheduled 60-day duration.
