Recently, the Department of Foreign Trade under Thailand’s Ministry of Commerce issued an announcement, launching an anti-dumping investigation into polyvinyl chloride (PVC) originating from Chinese mainland and Chinese Taiwan, in response to applications filed by domestic Thai enterprises.
In recent years, China’s PVC exports have mainly flowed to Southeast Asia and neighboring regions. Driven by steady domestic demand and infrastructure development in Thailand, China’s PVC shipments to the country have grown continuously. Export volumes surged from 30,000 metric tons in 2022 to roughly 120,000 metric tons in 2025. Even so, Thailand only accounts for a small share of China’s total PVC exports, standing at 3% to 3.5%.
Looking at China’s PVC export performance from January to May 2026, March recorded the highest shipment volume to Thailand at approximately 40,600 metric tons, making up 5.94% of China’s overall PVC exports that month.
The newly initiated Thai anti-dumping probe is likely to push up export costs for Chinese PVC suppliers targeting Thailand. It is projected that China’s PVC export volumes to Thailand will decline, and small and medium-sized manufacturers may exit the Thai market. Meanwhile, domestic enterprises will accelerate expansion into non-Southeast Asian markets including the Middle East, Africa and Latin America. Some suppliers may shift to exporting finished PVC products such as pipes and profiles manufactured in Thailand, facilitating an upgrade of China’s export mix from raw material supply to high-value finished goods.
Last Friday, domestic chemical futures posted broad gains: pure benzene rose 2.31%, polypropylene (PP) climbed 1.95%, polyethylene (PE) increased 1.92%, propylene gained 1.74%, PVC edged up 1.39%, general plastics rose 1.06%, and staple fiber advanced 1.05%. Paraxylene, PTA and PET bottle chips also registered varying degrees of price hikes.
