Two numbers tell most of the story this month. USD 1,467.32 per metric ton in China. USD 1,659.04 in the USA. Both logged for September 2026, both feeding into how October’s propylene glycol price trend is shaping up. A gap of USD 191.72 per ton isn’t small change once you’re buying in bulk.

Propylene glycol doesn’t get much attention outside industry circles, but it’s everywhere. Antifreeze, cosmetics, food additives, pharmaceutical formulations. A derivative of propylene oxide, produced mainly through hydration, and tightly linked to how oil and gas feedstock markets are behaving at any given time.

Propylene Glycol Latest Prices October 2026

• Propylene Glycol – China: USD 1,467.32/MT (FOB), September 2026

• Propylene Glycol – USA: USD 1,659.04/MT (CIF), September 2026

Price Source: Procurement Resource

China’s figure is FOB, pricing at the point of export, before freight or insurance get added. The USA figure is CIF, landed cost with freight and insurance already built in. So part of that USD 191.72 difference comes from the incoterm structure itself, not just raw production economics.

Still matters though. Buyers comparing supplier quotes across regions need to know which basis they’re actually looking at. Mixing up FOB and CIF numbers leads to bad sourcing decisions more often than people admit.

What’s Pulling the Prices Apart

Feedstock costs sit at the center of this. Propylene glycol tracks propylene oxide pricing closely, and propylene oxide tracks crude oil and natural gas. China’s domestic feedstock access, plus its scale of petrochemical production, tends to keep export pricing on the lower end.

The USA runs a different setup. Energy costs there have their own rhythm, shaped by domestic gas prices and refinery output. Add CIF freight and insurance on top, and the landed cost climbs.

Demand plays a role too. China exports heavily into Asian manufacturing supply chains. The USA serves a market with strong pharmaceutical and food-grade demand, categories where buyers often pay a premium for certified purity and tighter quality control.

Currency swings matter here as well. Propylene glycol trades globally in dollars. When regional currencies move against the dollar, delivered costs shift even if nothing changes at the production level.

Why This Trend Matters for Buyers

Sourcing teams watching the propylene glycol price trend aren’t just tracking numbers for curiosity. Contract timing, supplier negotiations, inventory planning. All of it depends on knowing where prices stand and where they’re likely headed.

China’s lower FOB price looks appealing at first glance. But freight costs from China to Western markets can eat into that advantage fast. Lead times stretch longer too, which matters for anyone running lean inventory.

USA-sourced propylene glycol costs more upfront. For buyers needing pharmaceutical or food-grade material with strict documentation, the shorter supply chain and tighter regulatory alignment can offset the price gap.

Investors tracking petrochemical derivatives should note something else. A sustained China-USA spread like this one often signals capacity differences that take years to close. Not a short-term blip.

What to Expect Going Forward

Nobody can call exact numbers for next month. Feedstock volatility makes that a losing game. But the structural gap between China and the USA looks likely to hold through the rest of 2026, barring a major shift in crude oil pricing or a sudden capacity expansion somewhere.

Buyers locking in long-term contracts should build in room for movement. Treating September 2026 figures as fixed for the next six months would be a mistake. Petrochemical pricing shifts faster than that, often on short notice.

Keeping tabs on both FOB and CIF benchmarks, region by region, stays the smarter approach. One number alone rarely tells the full picture.

Final Word

Propylene glycol’s October 2026 trend comes down to a clear split: China at USD 1,467.32/MT FOB, the USA at USD 1,659.04/MT CIF, both reported for September 2026. Incoterm differences explain part of the gap. Feedstock access, regional demand, and currency movement explain the rest. For sourcing teams and anyone watching petrochemical markets, this spread is worth tracking closely heading into Q4.

FAQ Section

Q: What is the current propylene glycol price trend between China and the USA? A: As of September 2026, China’s propylene glycol is priced at USD 1,467.32/MT FOB, while the USA sits at USD 1,659.04/MT CIF. The difference reflects both incoterm basis and underlying feedstock and freight cost structures.

Q: Why is propylene glycol more expensive in the USA than in China? A: The USA price includes CIF costs, freight and insurance bundled in, unlike China’s FOB figure. USA feedstock economics and demand from pharmaceutical and food-grade buyers also push pricing higher.

Q: What drives propylene glycol prices overall? A: Propylene oxide costs drive most of it, since propylene glycol is derived from it. Crude oil and natural gas prices, regional production capacity, and currency fluctuations all factor in as well.

Q: How often do propylene glycol prices change? A: Prices can shift monthly or even more frequently depending on feedstock swings. The September 2026 figures here serve as a reliable benchmark, but buyers should confirm current rates before finalizing contracts.

Q: What’s the outlook for propylene glycol prices heading into Q4 2026? A: The China-USA price gap is expected to persist through Q4 2026, tied to structural differences in feedstock access and regional demand. Sudden shifts in crude oil pricing could narrow or widen that spread.
