C9 (also written as C9 aromatic fraction or C9 aromatics) is a complex mixture of aromatic hydrocarbons containing predominantly nine carbon atoms per molecule, obtained as a co-product during the steam cracking of naphtha or gas oil for ethylene production, or from catalytic reforming of naphtha in refineries. The main components include trimethylbenzenes (1,2,3-, 1,2,4-, and 1,3,5-trimethylbenzene), indane, indene, cumene (isopropylbenzene), propylbenzenes, and small amounts of C8 and C10 aromatics. In its raw form it is a yellowish to colorless liquid with a characteristic aromatic odor, boiling roughly in the range of 155–180°C. C9 aromatics are widely used as feedstock for hydrocarbon resins (C9 petroleum resins), as solvents in coatings and adhesives, and as blending components in gasoline. The term 'C9' can also refer specifically to individual pure components such as mesitylene (1,3,5-trimethylbenzene) or pseudocumene (1,2,4-trimethylbenzene) when isolated by distillation or extraction.

Price Trajectory, latest 12 months (2025-08 to 2026-07)
The monthly customs export unit value for HS 270750 moved from USD 696.44/ton in 2025-08 to USD 991.33/ton in 2026-07 (+42.3% across the window). The window high was USD 1,047.36/ton in 2026-06 and the low USD 665.29/ton in 2026-01. Three-month averages put the latest quarter +17.3% against the previous one, which is classified here as bullish.
The same panel reported USD 3,201.5 million of export value on 3,800,211 tonnes over the twelve months, an average of 316,684 tonnes a month. Values are customs returns for the stated HS heading, so they capture the traded mix of that heading rather than a single quoted grade.
The EU side of the same market is one month fresher than the panel above: Eurostat Comext records EU27 imports of HS 270750 from outside the EU at USD 1,117.83/ton in 2026-08 (EUR 964.22/ton at the ECB monthly reference rate), +14.2% against 2026-07, on 140,229 tonnes; the twelve months to 2026-08 totalled 1,385,296 tonnes. On the 11 months the two datasets share (2025-09 to 2026-07), three-month blocks that far apart moved +41.2% on the export panel and +30.0% on the EU import side, so the two agree on direction. Import values are recorded on a CIF-type basis by a single bloc, so the level is not comparable with the export panel — the comparison above is directional.
2026-08 is not used yet: 6 of the listed reporters had filed both value and net weight for this heading when this page was rebuilt, against the 11 that make up the locked panel used here, and 2026-09 had no filings at all. Mixing a partly-filed month into a fixed panel would move the unit value through composition alone, so the window is held at 2026-07 until the panel for 2026-08 is complete.
HS 270750 covers aromatic hydrocarbon mixtures of which 65% or more by volume distils below 250 C, so this is a cut rather than a molecule; it also carries non-C9 aromatic solvent mixtures, and the C9 resin feedstock grade is not separated inside the heading.
Supply-side factors
- Fixed reporting panel of 11 economies: BRA (76), CAN (124), CZE (203), DNK (208), DEU (276), MYS (458), NLD (528), PRT (620), IND (699), SWE (752), USA (842). The panel is held constant in every month of the window so month-to-month movement is not a composition effect.
- Monthly unit value range over the window: USD 665.29 to USD 1,047.36/ton.
- Latest month, 2026-07: USD 991.33/ton, -5.3% against the previous month, on 389,554 tonnes.
Demand-side factors
- C9 aromatics demand is set by C9 petroleum resin for adhesives, rubber and coatings, by aromatic solvent use, and by the residual value as a cutter stock or fuel component, so resin plant run rates matter more than solvent demand.
- Related market pages on this site: C9 Petroleum Resin, Blended Solvent Oil and Xylene — C9 Petroleum Resin for the main upgrade outlet; Blended Solvent Oil for the solvent outlet for the same cut; Xylene for the lighter aromatic cut.
