BPA Actual Transaction Price Crashes to CNY 9,100/tonne

As a Hong Kong-based resin and valve import/export trader, Loonwan raised the "cost collapse" scenario probability from 45% to 55% just yesterday (Sep 29), and today's actual transaction data provides immediate validation. Juhua Digital Mall's latest Sep 30 quotes show Shandong Xima Supply Chain and Shandong Qiangsen Chemical both listing bisphenol A premium grade at CNY 9,100/tonne, CNY 2,090 below the SunSirs benchmark of 11,190. Toocle's same-day data shows Jiangsu Xile Energy's domestic premium ex-factory price at CNY 9,300/tonne, while Kumho Korea imported BPA holds at CNY 11,200/tonne — the domestic-import spread has widened to CNY 2,100/tonne. Loonwan judges this is not "quote volatility" but an actual BPA price crash: the 11,190 benchmark is a severely lagging "paper price," and the real market has already fallen back to early-September levels (Sep 1 benchmark was 9,310) or below. This means epoxy resin cost support is rapidly eroding, and E-51 prices may see a sharp correction in the first week of October.

Analysis across dimensions is as follows:

Unprecedented Price Gap: Benchmark 11,190 vs. Actual Ex-Factory 9,100 — Who Still Believes the Benchmark?

• SunSirs Benchmark: CNY 11,190/tonne on Sep 29, up 20.19% from Sep 1's 9,310. But the benchmark has been flat for days, reflecting "inertia" from the early-month surge.

• Juhua Digital Mall Actual Quotes (Sep 30):

  • Shandong Xima Supply Chain: CNY 9,100/tonne (premium grade, Zibo, Shandong)

  • Shandong Qiangsen Chemical: CNY 9,100/tonne (premium grade, Shandong)

  • CNY 2,090 below benchmark

• Toocle Actual Quotes (Sep 30):

  • Jiangsu Xile Energy: domestic premium ex-factory CNY 9,300/tonne

  • Kumho Korea imported: market CNY 11,200/tonne

  • Domestic-import spread CNY 1,900–2,100/tonne

• Loonwan's Assessment: A CNY 2,090/tonne gap between the 11,190 benchmark and 9,100 actual ex-factory price is extremely rare in BPA market history. This means: first, the benchmark severely lags the actual market; second, domestic BPA producers are already selling far below "official quotes" — due to inventory buildup and insufficient orders. Any buyer still using the 11,190 benchmark for procurement decisions is overpaying by CNY 2,000/tonne for a "paper price."

Cost Transmission Chain: BPA Crash → Epoxy Cost Support Collapses → October Price Correction

• BPA Share of Epoxy Cost: approximately 60–65%. BPA actual transaction price moved from 9,300 (early month) → 11,190 (mid-month benchmark peak) → 9,100 (current actual), a swing of over CNY 2,000/tonne.

• Epoxy Theoretical Cost: Based on BPA 9,100 + epichlorohydrin 7,650 + processing ~2,500, E-51 theoretical cost is approximately CNY 13,500–14,000/tonne — far below the current 15,650 benchmark.

• Other Feedstocks: Epichlorohydrin at CNY 7,650/tonne on Sep 29 (flat); propylene oxide 10,700→11,200 (slight increase) — other feedstocks haven't fallen in lockstep, but BPA is the largest component and its decline is enough to pull overall costs down.

• SunSirs August Forecast: "Wants to rise but can't, easy to fall and hard to rebound" — this judgment has fully materialized in September.

• Loonwan's Assessment: BPA at 9,100 actual means epoxy producers' feedstock costs have dropped sharply. While producers may try to maintain 15,650 quotes (digesting high-priced BPA inventory bought early in the month), newly purchased BPA costs have already fallen, giving producers ample room to cut prices after mid-October. Loonwan expects E-51 to test CNY 14,500/tonne in the first week of October, potentially falling to CNY 13,500–14,000/tonne by mid-October.

Domestic vs. Import Spread of CNY 2,100: Trade Arbitrage Window Opens

• Domestic BPA: CNY 9,100–9,300/tonne (actual ex-factory from Shandong, Jiangsu producers)

• Imported BPA: Kumho Korea CNY 11,200/tonne (market price)

• Spread: CNY 1,900–2,100/tonne

• Loonwan's Assessment: A CNY 2,100/tonne domestic-import spread is a clear arbitrage signal for traders. For epoxy and PC producers using BPA as feedstock, now is the time to prioritize domestic BPA over imports — quality differences are narrowing (domestic premium grade already meets most epoxy production needs), but the price gap is CNY 2,100/tonne. For Loonwan's clients, if your epoxy supplier is still quoting based on imported BPA, you have every reason to demand a price cut — their feedstock cost has already dropped by CNY 2,000/tonne.

Last Trading Day Before National Day Holiday: Pre-Holiday Effect Amplifies Price Volatility

• Timing: Today is Sep 30, the last trading day before the National Day holiday. Domestic market closed Oct 1–7.

• Pre-Holiday Effect: Producers typically cut prices before holidays to raise cash and reduce inventory; buyers wait and watch for post-holiday prices.

• Historical Reference: On Sep 30, 2022, East China BPA market "fell 明显，market quotes down 500 to 15,600/tonne, pre-holiday restocking ended, trading turned thin, center of gravity declined" — pre-holiday declines are normal.

• Loonwan's Assessment: During the 7-day holiday, international crude and chemical prices may continue to fluctuate. If international oil prices fall during the holiday (US-Iran easing or OPEC production increase), BPA and epoxy may gap down after the holiday. Buyers should not chase high prices to restock before the holiday; wait for the Oct 8 opening to observe price direction before deciding.

Practical Procurement & Trade Guidance: Immediately Adjust Procurement Strategy

• Domestic Procurement Advice (updated):

  • BPA actual price at 9,100, epoxy theoretical cost down to 13,500–14,000.

  • Loonwan lowers the E-51 restock trigger from yesterday's 13,500 to CNY 13,000/tonne — because BPA's actual crash exceeded expectations.

  • If E-51 falls below 14,000 in the first week of October, small trial orders; below 13,500, normal restocking; below 13,000, increase inventory.

• Export Perspective:

  • Rapidly falling domestic BPA and epoxy prices are positive for exporters — FOB quote competitiveness improves.

  • But note: US epoxy Q2 prices also fell 8.17% QoQ, global synchronized weakness. Export arbitrage depends on whether domestic declines outpace international declines.

  • Now is a good time to quote for export — domestic costs are falling fast but overseas customers haven't yet realized China's price crash; lock in orders before overseas prices adjust.

• Scenario Probability Update (vs. Sep 29):

  • Cost collapse: 70% (sharply up from 55%) — BPA actual at 9,100 has validated

  • High-level oscillation: 20% (down from 30%) — benchmark may stay flat but actual has crashed

  • Demand surge: 10% (down from 15%) — pre-holiday demand weak, no catalyst

• Loonwan's Assessment: Yesterday we said "October's main theme is correction," and today's data shows the correction has already begun — faster and deeper than expected. BPA actual at 9,100, CNY 2,090 below benchmark, is not "may fall" but "has already fallen." The benchmark's lag gives buyers a time window: before the benchmark adjusts down, negotiate with suppliers using actual transaction prices and secure purchase prices far below the benchmark.

Loonwan advises global resin procurement clients: BPA actual transaction prices have crashed to CNY 9,100/tonne, CNY 2,090 below benchmark — cost collapse is actually happening, adjust procurement strategy immediately. Key actions: first, stop using the 11,190 benchmark for procurement decisions — actual ex-factory is already 9,100–9,300; second, lower the E-51 restock trigger to CNY 13,000/tonne, with small trial orders if it falls below 14,000 in the first week of October; third, prioritize domestic BPA over imports — the CNY 2,100/tonne spread more than covers quality differences; fourth, do not chase high prices to restock before the National Day holiday, wait for the Oct 8 opening to observe direction. For export traders, this is a window to lock in export orders — domestic costs are falling fast but overseas customers haven't yet perceived it, so competitive FOB quotes can secure orders before overseas prices adjust. Loonwan will continue tracking international crude and BPA overseas prices during the National Day holiday, and provide post-holiday price forecasts and procurement advice immediately after the Oct 8 opening.
