After approximately 4.2 million metric tons of PET resin capacity was added in 2024 and 2.0 million tons in 2025, only about 500,000 tons per year came onstream during H1 2026.
Major Chinese producers, including Yisheng, Sanfangxiang, CRC and Zhejiang Wankai, have maintained operating-rate reductions of around 20% since July 2025. Combined with slower capacity growth and geopolitical disruption, this discipline supported a significant recovery in PET resin prices and producer margins.
An additional 700,000 tons per year of capacity is expected to start in H2, while several plants return from extended shutdowns. This will renew pressure on processing margins unless producers continue to restrain operating rates.
China exported approximately 2.7 million metric tons of PET resin from January through May 2026, up just 0.2% year on year. Stronger shipments to Southeast Asia, up 15.6%, supported the total. Vietnam expanded exports rapidly to South Korea and Taiwan, emerging as the fastest-growing supplier and increasing competition in regional trade.
The timing of operating-rate increases by China’s major producers will be decisive. A rapid return of capacity could weaken margins, while continued production discipline would help absorb new supply and preserve pricing stability.
