Propylene glycol (PG), a versatile colorless liquid with the formula C₃H₈O₂, is a vital chemical widely used across industries. It serves as a key raw material for unsaturated polyester resins, antifreeze solutions, cosmetics, food additives, and pharmaceutical formulations. Thanks to its low toxicity and excellent solvency, PG has maintained stable global demand in recent years.

China has emerged as the world’s leading PG producer and exporter, with capacity expanding steadily to meet both domestic and international needs. In 2024, China’s PG exports reached 249,300 tons, up 21.38% year-on-year, and the growth continued into 2025. The first half of 2025 saw exports hit around 140,000 tons, a 31.09% year-on-year increase.

Southeast Asia remains the largest export destination, accounting for over 40% of China’s total PG exports, followed by India and Turkey. The RCEP agreement has boosted exports by reducing tariffs, making Chinese PG more competitive in regional markets. While industrial-grade PG dominates exports, demand for high-purity USP/EP grade for pharmaceuticals and cosmetics is rising, though it still faces competition from Western manufacturers.

Overall, China’s PG export outlook remains positive, driven by robust overseas demand and improved product quality. With ongoing technological upgrades and expanding global market access, China’s PG exports are expected to maintain steady growth in the near future.
