The US cyclohexanone price trend softened into mid-October 2026 after a September uptick, according to ChemAnalyst, even though refinery outages and firmer benzene had pushed costs up. In short, feedstock is tight but buying is not: downstream users are purchasing close to immediate need, and ChemAnalyst's outlook points to modest further softness in November before prices turn upward toward March 2027. For procurement teams in Southeast Asia, this looks less like a shortage and more like a window to review cover before the spring.
What is driving the cyclohexanone price trend in the US?
Two forces are pulling in opposite directions. On the cost side, ChemAnalyst links September's rise to firmer benzene benchmarks and refinery outages. On the demand side, it describes routine post-summer offtake and hand-to-mouth purchasing, which has limited spot activity and let prices slip back.
The headline "tug-of-war" matters because the two sides operate on different timescales. Weak buying can take the premium out of a market within weeks. A feedstock constraint can sit underneath that market, unnoticed, until buyers come back at the same time.
Why refinery outages reach cyclohexanone at all
Cyclohexanone is usually made in one of two ways: by oxidising cyclohexane into a cyclohexanone and cyclohexanol mixture known as KA oil, or by hydrogenating phenol. Both routes trace back to benzene. Cyclohexane is produced by hydrogenating benzene, and phenol is commonly made from benzene through the cumene process.
A large share of benzene comes from refinery and petrochemical aromatics streams. When a refinery runs below plan, aromatics availability can fall and benzene firms, and that cost reaches a cyclohexanone producer whether or not its own customers are buying. This is why producer margins can tighten while the delivered market looks quiet.
Thin merchant volumes make cyclohexanone supply harder to read
The most useful detail for an importer is structural. ChemAnalyst puts roughly three-quarters of production as captive to caprolactam and adipic acid, meaning most of the output never reaches the open market. The remaining merchant volume serves solvent, coatings and intermediate users.
That split also explains why a merchant buyer and an integrated producer can read the same market differently. The producer is deciding where its own molecules earn the most. The merchant buyer only sees what is left, so the first sign of a change is often a shorter offer list rather than a higher quote.
A thin merchant pool behaves differently from a large one:
- Small changes carry further. If an integrated producer keeps more for its own caprolactam line, merchant buyers feel it more sharply than the overall supply figure suggests.
- Quiet markets can mislead. Soft prices during hand-to-mouth buying say little about how much material would be available if several sectors restocked together.
- Grade matters. A replacement offer only helps if the grade, purity and documents fit your process, and requalifying takes longer than a quote.
What the cyclohexanone price trend means for buyers in Southeast Asia
A US market reading does not set prices in Bangkok or Ho Chi Minh City, where much of the regional supply comes from Asian producers. It is still worth tracking, because benzene is a global signal and product can be reallocated when regional price gaps open. The effect depends on how each user buys:
| Buyer segment | How cyclohexanone is used | What to watch |
|---|---|---|
| Paints, coatings and inks | Strong solvent for vinyl and nitrocellulose resins | Whether formulations can tolerate a solvent blend change if supply narrows |
| PVC adhesives and processing | Solvent for PVC systems | Purity and water content when a supply origin changes |
| Chemical and agrochemical synthesis | Intermediate in selected synthesis routes | Requalification time for a new source |
| Nylon chain | Precursor to caprolactam and adipic acid | Integrated producers' operating rates, which decide how much reaches the merchant market |
The practical question for each of these buyers is not where the US index sits this month. It is how long the plant could keep running on current stock and approved sources if one supplier reduced its offer, and whether that answer still holds if the spring upturn arrives on schedule.
A cyclohexanone planning checklist for the next two quarters
- Track benzene and cyclohexane alongside cyclohexanone. The feedstock moved first in September, while buying weakness masked it later.
- Use the softer period to confirm safety stock against your actual lead times rather than average conditions.
- Qualify at least one alternative source now, including grade, COA and packaging, while there is no pressure to switch.
- Note planned refinery and aromatics turnarounds into the first quarter of 2027, since a forecast upturn toward March leaves little slack if restocking and outages coincide.
- Treat any single report as one reading. Published indices for this material can differ by basis and period, so compare direction over time rather than single figures.
Cyclohexanone FAQ
Are cyclohexanone prices rising or falling?
According to ChemAnalyst, US prices rose in September 2026 on firmer benzene and refinery outages, then softened into mid-October as buying stayed thin. Its outlook points to modest softness in November and an upward direction toward March 2027.
Is there a cyclohexanone shortage?
The reporting does not describe a shortage. It describes feedstock-driven tightness beneath weak demand. The risk is that thin merchant volumes leave limited room if several sectors return to buying together.
Why do refinery problems affect cyclohexanone?
Both main production routes depend on benzene, and a large share of benzene comes from refinery and petrochemical aromatics streams. Lower refinery output can raise feedstock cost before it shows up in cyclohexanone demand.
What is cyclohexanone used for?
Most of it goes into caprolactam for nylon 6 and adipic acid for nylon 6,6. It is also used as a strong solvent in coatings, inks and PVC systems, and as an intermediate in chemical synthesis.
How DIC approaches cyclohexanone supply planning
A soft market is the easiest time to build a supply plan, and the hardest time to feel you need one. DIC works with manufacturers in Thailand, Vietnam and across Southeast Asia on inventory planning, including VMI programs for steady draw-down and an IBC drum channel that lets order size follow actual consumption rather than ISO tank logistics. Availability and grades are confirmed per lot. To talk through your cyclohexanone requirements for 2027, contact our team through the inquiry form.
