Terephthalic acid (TPA) is an aromatic dicarboxylic acid produced from paraxylene through catalytic oxidation, used as the primary feedstock for polyester fiber, PET resin, and polyester film manufacturing. Paraxylene feedstock costs, and polyester and PET resin demand all feed into the price.
Global terephthalic acid prices in Q1 2026 stood at USD 0.992 per KG in North America, the highest among tracked markets, USD 0.766 per KG in Southeast Asia, USD 0.735 per KG in Europe, and USD 0.706 per KG in Northeast Asia, the most competitively priced tracked market. North America held the highest tracked price on elevated domestic paraxylene feedstock and logistics costs, while Northeast Asia benefited from ample regional production capacity. Steady polyester fiber and PET resin demand continued to underpin consumption across all tracked regions.
Terephthalic acid prices held close to Q1 2026 levels through August 2026, tracking regional paraxylene feedstock cost differentials, as steady polyester fiber and PET resin demand continued to support the market across all tracked regions.
The rest of the year of 2026 looks stable to slightly firmer. Ample capacity caps any rally, but a firmer paraxylene backdrop and the steady PET demand put a floor under the prices, and the forecast bands sit a touch above current levels. A crude or paraxylene spike, or a PET restocking wave, would lift prices. A fresh round of Chinese capacity, or weak textile demand, would push them back down.
| Region | 2026 Price Range (USD/KG) | Outlook |
| Global Average | 0.805 - 0.940 | Stable; ample capacity meets steady polyester demand |
| North America | 0.994 - 1.182 | Highest; tighter regional supply holds a premium |
| Southeast Asia | 0.768 - 0.882 | Firming; restocking and paraxylene costs lift prices |
| Europe | 0.738 - 0.863 | Easing; soft polyester demand pulls prices down |
| Northeast Asia | 0.720 - 0.833 | Lowest; vast Chinese capacity anchors the floor |
North America had eased into a value of 3.7% to USD 0.992/KG in Q1 of the year 2026. It had been slipping below the dollar mark for the first time in the period. Softer paraxylene costs and steady but unspectacular PET demand pulled prices down. The region kept its premium over the rest, just by a narrower margin.
Why did the price of Terephthalic Acid (TPA) change in Q1 2026 in North America?
Softer paraxylene costs and steady PET demand eased prices 3.7% to USD 0.992/KG.

Terephthalic acid held a tight range across the six quarters, the global average moving from USD 0.798/KG in Q1 2025 to USD 0.800/KG in Q1 2026, a net change of just 0.3%. Ample capacity and steady polyester demand kept the market balanced, with a soft patch in late 2025 and a firm rebound to start 2026. Paraxylene costs set the backdrop throughout.

Terephthalic acid was broadly flat in 2025, the global average easing from USD 0.798/KG in Q1 to USD 0.785/KG by Q4, down 1.6%. Three forces shaped the year. Ample and still-growing Chinese capacity kept the floor down. Steady but unspectacular polyester and PET demand gave the market a base. And a soft paraxylene backdrop held the cost side in check. The regions diverged only modestly around the flat headline.
North America held the top of the table, barely moving from USD 1.029/KG in Q1 2025 to USD 1.030/KG by Q4, up 0.1%. Tighter regional supply sustained the premium all year. Balanced supply and demand was the dominant driver, keeping the market steady near a dollar.
Southeast Asia eased through the first three quarters, from USD 0.734/KG in Q1 2025 to a USD 0.700/KG Q3 low, before recovering to USD 0.726/KG by Q4. Soft polyester demand drove the dip, restocking the recovery. Polyester demand swings were the dominant driver.
Europe eased from USD 0.762/KG in Q1 2025 to USD 0.743/KG by Q4, down 2.5%, after a brief Q2 firming. Weak polyester and PET demand pressed prices lower through the second half. Soft demand was the dominant driver.
Northeast Asia held the global floor, ranging from USD 0.642/KG to USD 0.668/KG through 2025 before a sharp early-2026 rebound. Vast Chinese capacity capped the market, with soft demand pressing it lower late in the year. Structural overcapacity was the dominant driver, keeping the region the cheapest source.
