Polysilicon Price Trend Q2 2026: Reading the Gap Between China and the USA
Polysilicon just posted fresh numbers for May 2026, and the polysilicon price trend right now tells an interesting story. China's sitting at USD 5,263.43/MT FOB. The USA? USD 5,382.19/MT CIF. That's a USD 118.76 gap. Not massive. But not something a solar manufacturer's finance team just shrugs off either.
Polysilicon feeds the entire solar supply chain — wafers, cells, modules, all of it starts here. So when this number shifts, everyone downstream feels it eventually. Panel makers, EPC contractors, even the utilities signing long-term power purchase agreements. All connected to this one raw material.
Current Polysilicon Prices: China vs USA
Numbers first.
| Product | Region | Incoterm Basis | Price | Last Updated |
|---|---|---|---|---|
| Polysilicon | China | FOB | USD 5,263.43/MT | May 2026 |
| Polysilicon | USA | CIF | USD 5,382.19/MT | May 2026 |
USD 118.76 difference per metric ton. Scale that across a multi-hundred-ton order and suddenly it's a real line item.
Quick context before anyone reads too much into that gap:
- China's price is FOB — the buyer picks up cost once goods clear the export port. Freight and insurance aren't included.
- The US figure is CIF, so freight and insurance are already rolled in. That alone explains a chunk of the spread.
- Both numbers reflect May 2026. Polysilicon moves fast — these aren't annual averages, and they won't stay fixed for long.
So is China actually "cheaper"? Kind of. FOB versus CIF isn't a clean comparison — part of that gap is just the shipping terms doing their job. Still a useful reference point though, especially for buyers trying to figure out where the real cost differences sit.
Why Polysilicon Prices Move the Way They Do
A few forces tend to drive this market more than anything else.
Production costs. Polysilicon manufacturing eats a lot of electricity — the Siemens process especially. Regions with cheaper power, like parts of China's Xinjiang and Yunnan provinces, can produce at lower cost. That production advantage shows up directly in the FOB price.
Solar demand cycles. Global solar installation targets drive polysilicon demand more than almost anything else. A strong quarter for panel orders pushes upstream demand for raw silicon almost immediately. Slower installation seasons do the opposite.
Trade policy. Tariffs, import restrictions, anti-dumping measures — polysilicon has seen plenty of all three over the years, particularly between China and Western markets. These policies can widen regional price gaps well beyond what production costs alone would justify.
Supply chain bottlenecks. Polysilicon capacity additions take years to come online. Short-term supply crunches — from plant maintenance shutdowns to raw material shortages for silicon metal — can spike prices quickly, since there's no fast way to add capacity.
A Few Questions Buyers Usually Ask at This Point
Is FOB China really the cheaper option once you factor everything in?
Not always. Add freight, insurance, and import duties to that FOB number, and the landed cost in the US can end up close to — or above — the CIF figure already quoted. Worth running the full math before assuming China wins on price.
Does the quality differ between regions?
Not inherently. Solar-grade polysilicon purity standards (99.9999% or higher, typically) are fairly consistent globally. Quality depends more on the specific producer's process control than on geography.
How much does this number actually move month to month?
Quite a bit, historically. Polysilicon has swung by double-digit percentages within a single quarter before, especially during supply shortages. May 2026's snapshot is useful, but treat it as a moving target, not a fixed benchmark.
What This Means for Buyers and Investors
Solar manufacturers locking in polysilicon contracts should treat this spread as a starting point for negotiation, not the final word. Landed cost varies by shipping route, contract length, and how much volume gets committed upfront.
Investors watching the solar supply chain might read the US premium as a signal — domestic polysilicon capacity in America has been expanding, partly to reduce reliance on imports and partly in response to trade policy pressure. Higher import costs tend to make that domestic buildout look more attractive on paper.
For procurement teams: this data point matters most when paired with forward contracts. Locking in at May 2026 pricing without checking how the market's trending into Q2 could mean overpaying if prices soften, or underpaying if they spike again.
Looking Ahead: Q2 2026 Outlook
Where's polysilicon headed for the rest of Q2? Hard to say with total confidence — this market's had a habit of surprising people.
What does look reasonably stable: the China-US spread, driven mostly by shipping terms and trade policy rather than raw production cost differences. That structural gap probably holds unless something changes on the tariff front.
Demand is the wildcard. Solar installation forecasts for 2026 remain strong across most major markets, and if that demand accelerates faster than new capacity comes online, prices could tighten from here rather than ease.
Conclusion
The polysilicon price trend for Q2 2026 puts China at USD 5,263.43/MT FOB and the USA at USD 5,382.19/MT CIF, both as of May 2026. That USD 118.76 spread reflects shipping terms, trade policy, and regional production costs working together — not just market noise. Anyone buying, selling, or investing around solar-grade silicon needs this number on their radar, because it moves fast and it moves the whole supply chain with it.
FAQ Section
What is the current polysilicon price trend for China and the USA?
As of May 2026, China's polysilicon runs USD 5,263.43/MT FOB, while the USA sits at USD 5,382.19/MT CIF. Shipping terms account for part of that gap, along with production cost differences and trade policy effects between the two markets.
Why is polysilicon cheaper in China?
Lower electricity costs in key production regions give Chinese manufacturers a real cost edge, since polysilicon refining is energy-intensive. The FOB pricing also excludes freight and insurance, unlike the CIF figure quoted for the US — so part of the gap is just shipping terms.
What drives polysilicon prices most?
Production costs — especially electricity — matter a lot, alongside global solar demand and trade policy. Supply bottlenecks can spike prices fast since new capacity takes years to build. Tariffs and anti-dumping measures have historically widened regional gaps too.
How volatile is the polysilicon market?
Quite volatile compared to most commodities. Prices have moved by double digits within a single quarter during past supply crunches. May 2026's numbers are a solid reference, but buyers should check for updates before locking in longer contracts.
What's the outlook for polysilicon prices in Q2 2026?
The China-US spread looks likely to hold through Q2 2026, mostly due to shipping terms and trade policy rather than production costs. Demand is the bigger unknown — strong solar installation growth could tighten supply and push prices up from current levels.
