Bisphenol A price movements have picked up noticeably over the past two weeks, and the shift is already showing up in feedstock costs for epoxy resin used across FRP, coatings, and composite tooling applications. For overseas buyers sourcing epoxy resin, curing systems, or bulk chemical intermediates from Chinese suppliers, the bisphenol a price trend is one of the more reliable early signals for where epoxy resin quotations are headed next.
This article looks at what the latest public price data shows, why bisphenol a price swings flow through to epoxy resin costs, and four practical questions buyers should ask before locking in their next purchase order.

Understanding the Latest Bisphenol A Price Data
According to SCI99 (Zhuochuang Information), the national mainstream market average price moved from RMB 9,350 per ton on August 27 to RMB 9,900 per ton on September 4, 2026 — a gain of RMB 550, or roughly 5.9%, in seven trading days.
The daily breakdown shows this was not a single spike: price held flat at RMB 9,350 for two sessions, then rose RMB 125 (1.33%) on September 1, RMB 150 (1.58%) on September 2, RMB 200 (2.07%) on September 3, and a further RMB 50 (0.51%) on September 4. Four consecutive daily increases point to sustained upward pressure rather than a one-off adjustment.
What’s Behind the Move
Bisphenol A sits upstream of epoxy resin production, and its cost is tied to feedstock inputs such as phenol and acetone, along with plant operating rates. The same public monitoring page also lists related commodities moving in the same window, including propylene oxide and ethylene oxide, part of the same upstream chemical cluster.
A rising bisphenol a price alongside firmer related feedstocks is generally read by buyers as a sign that resin producers have room, and possibly reason, to revise their own epoxy resin quotations upward in the near term.
Why This Matters for Epoxy Resin Buyers
Bisphenol A is a primary feedstock for standard liquid epoxy resin, so a sustained bisphenol a price increase typically works its way into epoxy resin quotations within days to a few weeks, depending on how much forward inventory a given producer is carrying.
For FRP fabricators, pultrusion operators, filament winding shops, and other buyers who purchase epoxy resin on a recurring basis, this upstream indicator is worth checking before confirming a new purchase order — not because it guarantees a specific price change, but because it narrows the range of likely outcomes.
Reading the Signal Without Overreacting
A single week of gains is not, by itself, proof that epoxy resin costs will rise by the same percentage. Currency movements, regional supply, and individual producer inventory positions all play a role.
What the current data does support is a reasonable case for buyers to review open quotations sooner rather than later, and to ask suppliers directly whether the recent bisphenol a price movement has already been factored into current epoxy resin offers.
Four Questions to Ask Before Your Next Epoxy Resin Order
- Has the increase already been priced in? Ask whether your quoted rate already reflects the latest bisphenol a price data, or whether it is still pending a producer revision.
- Is your price fixed or floating? Confirm whether your supplier’s epoxy resin quotation is fixed for a set validity period or subject to change at the time of shipment.
- Would splitting the order help? If your volumes allow it, ask whether placing a smaller confirmed batch now, with a follow-up order later, reduces your exposure if the trend continues.
- Are there comparison options? Ask your supplier whether alternative resin grades, or recommended international brand products such as those from Dow, can be quoted alongside your current option for comparison.
Is This a Lock-In Window?
Based on the public data through September 4, the trend has been upward for four straight sessions. Buyers commonly treat this kind of pattern as a reason to confirm near-term requirements rather than delay — though this is a directional read of published market data, not a guarantee of future pricing or a specific discount.
Buyers with flexible delivery schedules may still find it useful to request a firm quotation validity window from their supplier so their epoxy resin price is protected against further upstream movement.

Frequently Asked Questions
What is driving the current bisphenol a price increase?
Public data points to firmer upstream feedstocks such as phenol, acetone, and propylene oxide, combined with tighter plant operating rates, though the full breakdown of drivers is not disclosed in the free monitoring data.
Does a higher bisphenol a price always mean epoxy resin prices rise by the same amount?
Not necessarily. Epoxy resin pricing also depends on individual producer inventory, regional supply, and currency factors, so the relationship is directional rather than one-to-one.
How often is this price data updated?
SCI99 publishes daily monitoring figures for bisphenol A on its public price pages, which is the data referenced in this article.
Should I lock in my epoxy resin order now?
That depends on your inventory position and order timeline. Reviewing your open quotations against the current trend, and asking your supplier the questions above, is a reasonable first step before deciding.
