Diethanolamine Pricing, Demand and Supply Overview
Diethanolamine (DEA) is an ethanolamine compound produced from ethylene oxide and ammonia, used extensively in surfactant and detergent formulations, gas sweetening and treatment processes, and herbicide intermediates. Ethylene oxide and ammonia feedstock costs, and surfactant and gas treatment demand all feed into the price.
Global diethanolamine prices diverged by region through Q1 2026 into June, with Europe easing to USD 1.50 per KG in June, down 6.8 percent, on weakened surfactant and personal care demand, while Northeast Asia fell to USD 0.81 per KG, down 12.0 percent, on softening surfactant and agrochemical demand. North America held near USD 1.02 per KG, broadly unchanged, supported by strong surfactant, gas treatment, and agrochemical sector demand, while the Middle East rose sharply to USD 1.14 per KG, up 18.8 percent, on firming export demand even as South America fell 25.4 percent to USD 0.85 per KG.
What is Diethanolamine Price in August 2026?
Diethanolamine prices held a mixed tone through August 2026, tracking close to June 2026 levels across tracked regions, as diverging surfactant, gas treatment, and agrochemical demand continued to drive sharp regional divergence in pricing.
- North America: North American diethanolamine prices held near USD 0.97 to USD 1.07 per KG, close to the USD 1.02 per KG recorded in June 2026, as strong surfactant, gas treatment, and agrochemical sector demand continued to support the region's pricing.
- APAC (Northeast Asia): Northeast Asian diethanolamine prices held near USD 0.77 to USD 0.85 per KG, close to the USD 0.81 per KG recorded in June 2026 following a 12.0 percent decline, as softening surfactant and agrochemical demand continued to weigh on the region's pricing.
- Europe: European diethanolamine prices held near USD 1.43 to USD 1.58 per KG, close to the USD 1.50 per KG recorded in June 2026 and the highest among tracked markets, though weakened surfactant and personal care demand continued to ease the regional premium.
Diethanolamine Price Forecast for 2026
Having approached 2026 near multi-year lows in most regions, the DEA market is expected to stabilise gradually. Ethylene oxide feedstock costs had reached a near-term floor, limiting further downside. Gas treatment demand from the natural gas processing sector provides a structural demand base. Europe is expected to remain the highest-priced region in the USD 1.100 to 1.220/KG range. Northeast Asia and the Middle East face continued capacity overhang and are expected at the lower end of the range. The 5-region average is forecast in the USD 0.940 to 1.020/KG range for 2026.
| Region | 2026 Price Range (USD/KG) | Outlook |
| Global Average | 0.940 - 1.020 | Gradual stabilisation expected; gas treatment and personal care demand provide a demand floor |
| Europe | 1.100 - 1.220 | Gas treatment demand and supply discipline expected to sustain the highest regional price |
| Middle East | 0.820 - 0.940 | Partial recovery expected after 2025 correction; ethylene oxide cost stabilisation supports pricing |
| North America | 0.920 - 1.020 | Natural gas processing activity and personal care sector demand expected to support partial recovery |
| Northeast Asia | 0.810 - 0.920 | Capacity overhang limits recovery pace; ethylene oxide cost floor prevents further sharp declines |
| South America | 0.960 - 1.060 | Gas treatment sector demand expected to sustain prices near Q1 2026 levels |

Diethanolamine Prices in Europe
European DEA had eased 2.4% in Q1 2026 to USD 1.174/KG from USD 1.203/KG in Q4. Europe had retained the highest regional price by a considerable margin. Gas treatment demand from the natural gas processing sector had remained firm and personal care sector procurement had continued at steady volumes. The gradual decline had reflected the mild pass-through of global ethylene oxide cost reductions.
Why did the price of diethanolamine change in Q1 2026 in Europe?
Mild ethylene oxide feedstock cost pass-through had produced the 2.4% Q1 2026 ease while firm gas treatment and personal care demand had kept Europe at the highest regional price.
Diethanolamine Prices in the Middle East
Middle Eastern DEA had eased 2.2% in Q1 2026 to USD 0.861/KG from USD 0.880/KG in Q4. The market had been consolidating after the sharp 28.3% full-year 2025 decline. Ethylene oxide feedstock costs had stabilised, limiting further downside, though the capacity additions from 2025 had continued to weigh on the pricing structure.
Why did the price of diethanolamine change in Q1 2026 in the Middle East?
Ethylene oxide feedstock stabilisation had limited further decline to a modest 2.2%, with 2025's capacity additions continuing to weigh on the Middle East pricing structure.
Diethanolamine Prices in North America
North American DEA had recovered 3.4% in Q1 2026 to USD 0.962/KG from USD 0.930/KG in Q4. Natural gas processing sector activity had picked up in early 2026, increasing gas treatment demand for DEA scrubbing applications. The Q1 recovery had partially reversed the 13.7% full-year 2025 decline and represented the strongest Q1 2026 regional gain.
Why did the price of diethanolamine change in Q1 2026 in North America?
Increased natural gas processing sector activity had driven gas treatment demand recovery, producing the 3.4% Q1 2026 gain - the strongest among the five reporting regions.
Diethanolamine Prices in Northeast Asia
Northeast Asian DEA had eased 2.5% in Q1 2026 to USD 0.852/KG from USD 0.874/KG in Q4, holding near the reporting period's lowest regional level. Chinese production capacity that had come online through 2025 had continued to suppress pricing. The ethylene oxide input cost floor had prevented further sharp declines of the kind seen in Q3 and Q4 2025.
Why did the price of diethanolamine change in Q1 2026 in Northeast Asia?
Continued Chinese capacity overhang had produced the 2.5% Q1 2026 ease, though the ethylene oxide cost floor had limited the decline relative to 2025's sharper quarterly falls.
Diethanolamine Prices in South America
South American DEA had recovered 2.2% in Q1 2026 to USD 1.009/KG from USD 0.987/KG in Q4. Gas treatment sector procurement had firmed, with natural gas processing operations in Brazil and Argentina increasing DEA demand for acid gas removal. The Q1 recovery had followed the 6.3% Q4 2025 decline.
Why did the price of diethanolamine change in Q1 2026 in South America?

Diethanolamine Prices in Europe
European DEA had held flat in Q4 2025 at USD 1.203/KG, unchanged from Q3's level. After the Q3 decline, the market had found a near-term floor as gas treatment demand and personal care sector procurement had balanced available supply. Europe had been the only reporting region where prices had stabilised in Q4 rather than continuing to fall.
Why did the price of diethanolamine change in Q4 2025 in Europe?
Gas treatment and personal care demand had balanced available supply, producing price stability and keeping Europe at the highest regional level in Q4 2025.
Diethanolamine Prices in the Middle East
Middle Eastern DEA had fallen 9.3% in Q4 to USD 0.880/KG from USD 0.970/KG in Q3. The capacity additions that had come online during 2025 had continued to press prices lower, and export demand had remained subdued. The Q4 decline had extended the particularly sharp Q3 fall of 18.2%.
Why did the price of diethanolamine change in Q4 2025 in the Middle East?
Continued pressure from 2025 capacity additions and subdued export demand had driven the 9.3% Q4 2025 decline, extending the Middle East's H2 2025 correction.
Diethanolamine Prices in North America
North American DEA had fallen 5.9% in Q4 to USD 0.930/KG from USD 0.988/KG in Q3. After a brief Q3 stabilisation, the downward trend had resumed as natural gas processing sector DEA demand had moderated and ethylene oxide feedstock costs had continued to ease. The Q4 price had reached the 2025 cycle low.
Why did the price of diethanolamine change in Q4 2025 in North America?
Moderating gas treatment demand and continued ethylene oxide feedstock cost easing had driven the 5.9% Q4 2025 decline in North America.
Diethanolamine Prices in Northeast Asia
Northeast Asian DEA had fallen 9.2% in Q4 to USD 0.874/KG from USD 0.963/KG in Q3. New Chinese DEA capacity had been running at high utilisation rates, maintaining oversupply pressure. Regional buyers had held back discretionary purchasing amid the declining price environment. The Q4 result had extended the full-year decline to 20.8%.
Why did the price of diethanolamine change in Q4 2025 in Northeast Asia?
High Chinese capacity utilisation and buyer caution amid declining prices had driven the 9.2% Q4 2025 decline in Northeast Asia.
Diethanolamine Prices in South America
South American DEA had fallen 6.3% in Q4 to USD 0.987/KG from USD 1.053/KG in Q3. After the Q3 recovery, the market had given back gains as import supply had arrived at competitive prices from Middle Eastern and Northeast Asian producers. The Q4 decline had returned South America near its Q2 2025 level.
Why did the price of diethanolamine change in Q4 2025 in South America?
Competitive import supply from Middle Eastern and Northeast Asian producers had driven the 6.3% Q4 2025 decline, reversing South America's Q3 recovery.
Quarterly Diethanolamine Price Trends
The 5-region DEA average had followed a consistent downward path through 2025 before stabilising in Q1 2026. From USD 1.164/KG in Q1 2025, the average had declined each quarter to USD 0.975/KG in Q4, then held near-flat at USD 0.972/KG in Q1 2026. The cumulative Q1 2025-to-Q1 2026 decline was 16.5%.

What was Diethanolamine Price in 2025?
All five reporting regions had declined in 2025, making it a year of broad-based correction for DEA. The 5-region average had fallen 16.2% as ethylene oxide feedstock cost easing and capacity additions across key producing regions had compressed production margins. Three factors had defined the year:
- Ethylene oxide feedstock cost declines had reduced DEA production economics across all reporting regions, with the effect most acute in the Middle East and Northeast Asia where feedstock links were most direct
- Production capacity additions in the Middle East and Northeast Asia had created regional oversupply that had accelerated the price decline beyond what feedstock cost movements alone would have implied
- Gas treatment and personal care sector demand had provided a structural support in Europe and South America, producing the most moderate regional declines of 7.9% and 10.4% respectively
Diethanolamine Prices in Europe in 2025
From USD 1.307/KG in Q1 to USD 1.203/KG in Q4, a 7.9% full-year decline - the most moderate among the five regions. Gas treatment demand had provided a structural floor. Europe had held the highest regional price throughout 2025.
Diethanolamine Prices in the Middle East in 2025
From USD 1.228/KG in Q1 to USD 0.880/KG in Q4, a 28.3% full-year decline and the steepest in the dataset. Production capacity additions had compounded ethylene oxide feedstock cost easing, producing the most severe regional price correction.
Diethanolamine Prices in North America in 2025
From USD 1.078/KG in Q1 to USD 0.930/KG in Q4, a 13.7% full-year decline. A brief Q3 stabilisation had been followed by renewed Q4 weakness as natural gas processing demand had moderated and feedstock costs had continued to ease.
Diethanolamine Prices in Northeast Asia in 2025
From USD 1.104/KG in Q1 to USD 0.874/KG in Q4, a 20.8% full-year decline. New Chinese DEA capacity additions had maintained consistent oversupply pressure through the year, with Q3 and Q4 recording the sharpest quarterly declines at 14.0% and 9.2% respectively.
Diethanolamine Prices in South America in 2025
From USD 1.101/KG in Q1 to USD 0.987/KG in Q4, a 10.4% full-year decline. Gas treatment sector demand had supported a Q3 recovery, but competitive import supply from Middle Eastern and Northeast Asian producers had reversed those gains in Q4.
