Adipic Acid Price Trend and Forecast 2026-2027

What Is Adipic Acid and Why Does It Matter?

Adipic acid is one of the more widely produced dicarboxylic acids in the world, and most people interact with its downstream products every single day without knowing it. The nylon in a carpet, the foam cushion in a sofa, the plastic housing on a car door, the gelling agent in a soft drink, there is a reasonable chance adipic acid was somewhere in the manufacturing process. It is not a glamorous commodity, but its price movements feed through to a surprisingly wide range of consumer and industrial goods.

Chemically it is hexanedioic acid (C6H10O4), a simple six-carbon diacid with a structure that makes it particularly well-suited as a monomer for polymerisation. The dominant commercial production route involves two oxidation steps. First, cyclohexane is oxidised to a mixture of cyclohexanone and cyclohexanol, known in the industry as KA oil. Second, that KA oil is further oxidised using nitric acid to produce adipic acid. The feedstock chain runs cyclohexane from benzene, benzene from naphtha or coal, making adipic acid prices closely tied to crude oil and benzene market movements (ICIS; ACC).

There is an environmental dimension to adipic acid production that is worth understanding because it directly affects pricing in regulated markets. The nitric acid oxidation step releases nitrous oxide (N2O) as a by-product. N2O is a potent greenhouse gas, roughly 265 times more warming per molecule than CO2 over a 100-year period. European producers have invested heavily in N2O abatement technology and face EU ETS carbon compliance costs that Asian producers largely do not, which is a structural explanation for the persistent premium European adipic acid carries over North East Asian pricing (US EPA; European Commission).

From a market relevance standpoint, the reason adipic acid prices are worth tracking is that nylon 6,6 accounts for the vast majority of global adipic acid consumption. Nylon 6,6 demand is closely correlated with automotive production, carpet manufacturing, and industrial textiles, all of which are sensitive to economic cycles. When those sectors slow, adipic acid demand falls quickly. When they recover, it rebounds just as fast. That cycle sensitivity is why 2025 ended with such a sharp Q4 correction.

Which Sectors Are Driving Adipic Acid Demand?

• Nylon 6,6 Production: By far the largest end-use, accounting for the dominant share of global adipic acid consumption. Adipic acid reacts with hexamethylenediamine (HMDA) to form nylon 6,6, which is used in automotive components, carpet and rug fibre, industrial yarns, airbag fabrics, and engineering plastics. Automotive output cycles and the health of the US and European construction and renovation markets are the key demand drivers for this segment (ACC; ICIS).
• Polyurethane Polyols: Adipic acid is used to produce adipate polyester polyols, which are key raw materials for flexible polyurethane foams, coatings, adhesives, sealants, and elastomers. Furniture, automotive seating, and footwear are the primary downstream markets for this application, and demand in this segment tends to track consumer spending on durable goods (ICIS; European Coatings Association).
• Plasticizers: Dioctyl adipate and related adipate esters are used as plasticizers for PVC, particularly in applications requiring flexibility at low temperatures such as food packaging film, medical tubing, and cold-weather cables. This is a smaller but technically important segment where adipic acid commands premium pricing (ACC; US EPA).
• Food and Beverage: Food-grade adipic acid carries the designation E355 under EU food additive regulations and is approved by the US FDA as a GRAS substance. It is used as an acidulant, leavening agent, and flavour modifier in baking powders, gelatin desserts, fruit juices, and soft drinks. The volumes are modest relative to nylon but the quality specifications and pricing premium are considerably higher (FAO/WHO Codex Alimentarius; US FDA).
• Corrosion Inhibitors and Lubricant Additives: Adipic acid derivatives are used as corrosion inhibitors in metalworking fluids, hydraulic oils, and cooling water systems. This is a niche but consistent demand segment that is relatively insensitive to the broader economic cycles that drive nylon and polyurethane demand (ACC; ICIS).

Global Adipic Acid Price Trend in 2025

Global adipic acid prices in 2025 told a story in two distinct chapters. The first chapter ran from Q1 through Q2: a modest uplift as spring demand from nylon producers and polyurethane manufacturers picked up, with the global average nudging from USD 1.63/KG to USD 1.66/KG. Modest, almost unremarkable. The second chapter was considerably more dramatic. Benzene and cyclohexane feedstock costs softened through the second half of the year. Nylon 6,6 demand from automotive and carpet sectors came in below expectations. Chinese adipic acid capacity kept adding supply to an already well-supplied Asian market. And North America walked into Q4 and promptly shed 19.3% of its price in a single quarter.

The result was a year that ended significantly below where it started for most regions. The global average across four markets fell from USD 1.66/KG at its Q2 peak to USD 1.46/KG by Q4, a 12% decline in just two quarters. The averages below are calculated from the four regional markets covered in this report: Europe, North America, North East Asia, and South America.

The Q4 drop of 9.9% at the global level is the headline number, but it is worth understanding that it was largely driven by North America's outsized correction. Had North America performed more like Europe in Q4, the global average would have looked considerably more stable. The structural divergence between a North America heavily exposed to benzene feedstock swings and a Europe insulated by regulatory cost floors created a global average that masked the very different experiences of buyers in different markets.

European Adipic Acid Price Trends in 2025

Europe's adipic acid market had a steady and relatively unremarkable year by the standards of this report. Prices moved in a USD 0.10/KG range from Q1 through Q4, which in a year when North America shed nearly USD 0.46/KG in Q4 alone counts as exceptional stability. That stability is not accidental. European adipic acid production carries a cost structure that creates a floor under prices regardless of what is happening to feedstock costs elsewhere.

The EU ETS carbon pricing mechanism applies to the nitrous oxide emissions generated during the nitric acid oxidation step of adipic acid production. European producers have invested in abatement technology, but the residual carbon compliance costs remain real and ongoing. On top of that, European benzene and cyclohexane feedstocks are naphtha-derived and priced differently from the refinery by-product streams that feed North American production. REACH compliance adds administrative overhead. The result is a cost base that simply does not compress as quickly as North American pricing does when feedstock markets ease.

The Q2 gain of 5.1% was the most significant quarterly move Europe made all year and reflected genuine spring demand from nylon producers restocking ahead of the summer automotive production season. Q3 added a fractional 0.5%, which is more noise than signal. The Q4 pullback of 3.2% was real but modest, a reflection of the downstream demand softening that hit every region in Q4 rather than any structural change in European production economics. Europe ended the year at USD 1.81/KG, comfortably the most expensive market in this report alongside North America, and likely to maintain that premium through 2026.

North American Adipic Acid Price Trends in 2025

North America's adipic acid market handed out one of the more dramatic price corrections of any petrochemical commodity in Q4 2025. The year started confidently enough at USD 1.92/KG in Q1. Q2 added 6.8% to reach USD 2.05/KG, the highest price recorded across all four regions in any quarter of the year. Then Q3 gave back 3.9% as automotive sector demand signalled weakness. And Q4 simply fell off a cliff: down 19.3% in a single quarter to USD 1.59/KG. That is a USD 0.46/KG drop in three months.

Understanding what drove it means understanding the feedstock chain. North American adipic acid production is heavily tied to benzene, which itself is a by-product of catalytic reforming and steam cracking. US benzene prices are more volatile than European counterparts because the supply side includes significant refinery co-production that can swing sharply with crude oil runs. When benzene prices eased in H2 2025, adipic acid production costs fell, and in a market where North American nylon 6,6 demand from automotive and carpet sectors was already softening, those lower production costs fed through to spot prices quickly. Year-end inventory destocking by nylon producers who did not want to carry high-cost adipic acid into the new year accelerated the Q4 decline further.

North America ended 2025 at USD 1.59/KG, which is 17.2% below where it started the year. That full-year decline is striking, but it is worth noting that the Q4 correction may have over-shot on the downside. Year-end destocking tends to amplify price moves in both directions, and some recovery toward USD 1.70 to 1.80/KG in early 2026 looks reasonable if automotive demand stabilises and benzene feedstock costs stop falling. The structural cost case for North American producers remains intact. It was 2025's unusual combination of timing factors that made Q4 look as bad as it did.

North East Asian Adipic Acid Price Trends in 2025

North East Asia is where global adipic acid pricing finds its floor, and 2025 pushed that floor lower every single quarter. Prices dropped from USD 1.13/KG in Q1 to USD 0.98/KG by Q4, a full-year decline of 13.3% that left the region sitting below USD 1.00/KG for the first time in recent memory. The structural reason is not complicated: China has been adding adipic acid production capacity consistently, and the pace of new supply additions has been running ahead of regional nylon and polyurethane demand growth throughout the year.

The Q2 drop of 8.8% was the sharpest single-quarter move in North East Asia all year and reflected new Chinese capacity hitting the market just as seasonal demand from nylon producers was at its softest point between the New Year procurement cycle and the summer automotive season. Q3 and Q4 continued lower but at a more measured pace, suggesting the worst of the supply overhang had been priced in by mid-year and the remaining declines were driven by a combination of ongoing supply pressure and demand-side softness rather than any new shock to the market.

USD 0.98/KG in Q4 is the lowest price recorded across all four regions and all quarters in this report. For nylon and polyurethane producers in the region with the flexibility to buy on spot terms, that is a genuinely attractive input cost level. For Chinese adipic acid producers who have been running new capacity into a softening price environment, the margin picture is considerably less comfortable. Whether prices stabilise near USD 1.00/KG or push further lower in 2026 will depend on how aggressively Chinese producers are willing to run at current margins and whether nylon demand growth in regional end markets finally begins to absorb the supply overhang.

South American Adipic Acid Price Trends in 2025

South America's adipic acid market barely moved in the first half of 2025 and then gave back most of its ground in the second half. Prices held exactly flat at USD 1.71/KG through Q1 and Q2, a pattern that suggests a market in reasonable supply and demand balance, absorbing import cost signals from global markets without dramatic movement in either direction. Brazil accounts for the large majority of regional adipic acid demand, with consumption driven by polyurethane foam production for furniture and automotive seating, nylon engineering plastic compounders, and a modest food-grade segment.

The H2 deterioration followed a familiar pattern for an import-dependent region. As global adipic acid prices softened on the back of falling benzene costs and Chinese supply additions, lower-priced material from Asia and North America started arriving at South American ports at progressively cheaper landed costs. Local buyers, who had little reason to pay up for inventory in a falling market, waited rather than restocked. Prices dropped 5.8% in Q3 and a further 9.9% in Q4 as that competitive import pressure intensified and end-use demand from Brazilian automotive and furniture manufacturers softened in line with broader regional economic conditions.

South America closed 2025 at USD 1.45/KG, 15.2% below its Q1 opening price. That is a sharper full-year decline than Europe managed and only slightly less severe than North East Asia. For an import-dependent market, it was essentially a pass-through of the global price easing rather than a domestically driven correction. Brazilian automotive production and furniture manufacturing cycles will be the primary demand variables to watch in 2026, along with the direction of freight costs on trans-Atlantic and trans-Pacific import lanes that determine how quickly global price moves feed into South American landed costs.

What Factors Drove Adipic Acid Costs in 2025?

• Benzene and cyclohexane feedstock prices: Benzene is the starting material for cyclohexane, which is the starting material for adipic acid. Benzene prices move with crude oil, naphtha, and refinery run rates, and they are the most important short-term driver of adipic acid production costs globally. The H2 2025 easing in benzene prices was the primary catalyst behind North America's Q4 correction and the broader second-half softening across all four markets (ICIS; US EIA; European Commission).
• Chinese adipic acid capacity expansion: China has been the most consequential supply-side story in global adipic acid for several years. Domestic producers, including several large-scale operations in Liaoning, Henan, and Chongqing, continued to add capacity through 2025. That additional supply put consistent downward pressure on North East Asian spot prices throughout the year and, through the mechanism of competitive imports, added to the price softness in South America and parts of North America in H2 (USGS; China Customs GACC; ICIS).
• Nylon 6,6 demand from automotive and carpet sectors: Nylon 6,6 accounts for the vast majority of global adipic acid consumption, and its demand tracks automotive production and construction activity closely. Both sectors faced headwinds in 2025: global automotive output was affected by continued inventory management by OEMs, and US carpet and flooring demand softened as housing market activity remained constrained by mortgage rate levels. When nylon producers reduce their run rates, adipic acid demand falls quickly (ACC; World Steel Association; US Census Bureau Housing Data).
• EU ETS N2O compliance costs in European production: The nitric acid oxidation step of adipic acid production releases nitrous oxide, a potent greenhouse gas. European producers are subject to EU ETS compliance costs on these N2O emissions, which adds a per-tonne production overhead that North East Asian producers do not carry. This structural cost difference is the primary explanation for the persistent premium European adipic acid holds over North East Asian pricing, and it creates a floor under European prices that does not respond to feedstock market softening in the same way (European Commission; Eurostat; ECHA).
• Year-end inventory destocking: The sharp Q4 correction, particularly in North America and South America, was amplified by deliberate inventory reduction by nylon producers and polymer compounders who did not want to enter 2026 holding high-cost adipic acid purchased at Q2 peak prices. Year-end destocking is a recurring pattern in intermediate chemical markets, and in 2025 it coincided with genuine feedstock cost easing and demand softness, making the Q4 decline steeper than underlying market fundamentals alone would have produced (ICIS; ACC).
• Polyurethane demand from furniture and automotive seating: Adipate polyester polyols are used in flexible polyurethane foams for furniture, automotive seating, and footwear. Consumer spending on furniture and durable goods moderated through H2 2025 in several major markets, contributing to lower polyurethane polyol demand and reducing the pull-through for adipic acid beyond the nylon segment (ICIS; European Coatings Association; IEA).

Adipic Acid Market Forecast for 2026

The 2026 adipic acid market forecast does not point to a straightforward recovery, but it does not point to continued freefall either. The Q4 2025 correction, particularly in North America, looks partly like a year-end overshoot driven by inventory destocking behaviour rather than a pure reflection of underlying demand. Some price recovery in Q1 2026 is a reasonable expectation as that destocking works through and nylon producers return to market for routine replenishment.

The structural picture is more nuanced. Chinese capacity additions are not stopping. The North East Asian price floor at USD 0.98/KG sends a signal that regional supply is ample and that any significant demand recovery will need to be substantial to move the needle on pricing. European prices, protected by EU ETS compliance costs and naphtha-based feedstock pricing, are unlikely to fall as sharply as North America did in Q4 even if demand stays soft. South America's trajectory in 2026 will be almost entirely determined by two variables: Brazilian automotive and furniture demand, and the direction of global benzene feedstock costs.

North American pricing has the most recovery potential from its Q4 low, but that recovery will be capped by how quickly benzene feedstock costs stabilise and whether automotive sector demand picks up meaningfully through Q1 and Q2.

Expected Adipic Acid Price Range (2026):

North America carries the widest forecast range, reflecting genuine uncertainty about whether Q4 2025 represented a floor or a stepping stone to further declines. Europe's range is the narrowest of the higher-cost markets, anchored by structural production costs. North East Asia's ceiling is limited by ongoing Chinese supply additions, and the floor is somewhere around current levels unless domestic Chinese demand growth accelerates meaningfully.

Key Analyst Insights for the Adipic Acid Market

Adipic acid's 2025 price story was really two stories running in parallel. Europe had a stable year anchored by structural cost floors. North America had a year that started strong and ended dramatically. North East Asia declined quietly but consistently. South America tracked global feedstock moves with a lag. The divergence between those experiences tells you a lot about how differently the same commodity trades in markets with different feedstock structures and regulatory environments. Here is what matters most heading into 2026:

• The Q4 2025 North American correction of 19.3% is the most important data point for any adipic acid buyer or producer thinking about 2026. That kind of quarterly move is not purely a demand story. It is a combination of benzene feedstock easing, demand softness, and year-end destocking all arriving at the same time. Understanding which of those three factors will reverse in Q1 2026 matters enormously for contract timing. Benzene direction is the most critical variable to monitor.
• Chinese adipic acid capacity is the structural ceiling for global pricing in the medium term. North East Asian prices below USD 1.00/KG in Q4 reflect a market where supply has consistently been running ahead of demand growth. Unless Chinese capacity additions slow materially or nylon and polyurethane demand in Asia accelerates significantly, North East Asian prices are unlikely to recover to 2023 levels any time soon.
• Europe's structural premium over North East Asia held through 2025 and will continue to hold in 2026. The EU ETS N2O compliance cost for adipic acid production is real, ongoing, and growing as the ETS price trajectory trends upward. European buyers should plan for prices to remain above USD 1.70/KG as a base case and build contracts accordingly rather than waiting for parity with Asian pricing that is structurally impossible to achieve without a complete overhaul of European production economics.
• South America's H2 correction of 15.2% from Q2 to Q4 was largely imported rather than domestically driven. The region's full-year direction will continue to track global feedstock moves and import pricing from Asia and North America more than any domestic demand or supply factors. Brazilian automotive production and furniture sector activity are the local demand signals worth monitoring, but they will matter less to pricing than what happens in Shandong and Houston.
• Nylon 6,6 is the demand story that matters most for adipic acid. Automotive production volumes globally, US and European carpet and flooring demand, and the pace of engineering plastics substitution in industrial applications are the variables that determine whether the Q4 2025 correction was a market finding its level or the beginning of a prolonged soft period. The automotive sector's recovery trajectory in 2026, particularly in the US and Germany, will be the most important demand signal to track.
• The food-grade and plasticizer segments of the adipic acid market are worth monitoring as distinct pricing stories. Both trade at a premium to nylon-grade and both are less sensitive to the automotive and carpet demand cycles that drove the 2025 volatility. Producers who have diversified into food-grade and specialty plasticizer applications have a more stable revenue base than those concentrated in nylon feedstock supply.

Key Takeaways for Buyers and Manufacturers

For Buyers

• Watch benzene and cyclohexane prices as the leading indicators for adipic acid direction in North America and Europe. Both benchmarks moved ahead of adipic acid in 2025, and the Q4 correction was visible in benzene markets before it showed up in adipic acid spot prices. Buyers who track upstream feedstock markets have a one to two quarter window to adjust procurement strategies before the price moves reach them.
• North American buyers who locked in long-term contracts at Q2 peak prices paid a meaningful premium over what was available by Q4. The 19.3% intra-year swing between Q2 and Q4 is a strong argument for building quarterly price review mechanisms into supply agreements rather than annual fixed pricing in volatile feedstock environments.
• European buyers should treat USD 1.75 to 1.85/KG as the realistic pricing band for the foreseeable future. EU ETS N2O compliance costs are not going away, and the structural gap between European and North East Asian pricing reflects real production cost differences that will not close through market forces alone. Optimising within that cost reality, through specification management and supplier diversification, is more productive than expecting European prices to fall to Asian levels.
• South American buyers with flexible import sourcing should be evaluating whether Asian supply routes offer a meaningful cost advantage over North American or European suppliers given current price levels. With North East Asian adipic acid at USD 0.98/KG and South American landed prices at USD 1.45/KG in Q4, the import cost differential minus freight and duties is worth calculating for buyers who have not run that comparison recently.

For Manufacturers

• North American producers should resist the temptation to read the Q4 2025 correction as a structural market change rather than a cyclical and partly seasonal event. Year-end destocking amplified the decline beyond what feedstock fundamentals alone would have produced. The underlying demand base for nylon 6,6 in North America is not collapsing, and a measured recovery in Q1 and Q2 2026 is the more likely scenario than continued freefall.
• European producers' EU ETS N2O compliance costs are both a burden and a competitive moat. They create a cost floor that keeps European pricing above Asian levels, which benefits producers who have domestic European customers who cannot easily switch to imported Asian product. Maintaining that compliance position and demonstrating its environmental credentials to customers is increasingly a commercial argument in European industrial markets where sustainability sourcing matters.
• Chinese adipic acid producers adding capacity in a market where spot prices have already fallen below USD 1.00/KG should be modelling margin scenarios carefully. Volume for volume's sake at current price levels does not build a sustainable business. Differentiation into downstream nylon salt or finished nylon product, or into specialty adipic acid applications for food and cosmetics grades, offers better margin protection than commodity adipic acid spot sales at cycle lows.
• Producers supplying the South American market should be building supply chain reliability and local technical support relationships ahead of any demand recovery. In an import-dependent market where buyers have multiple origin options, suppliers who are known quantities in terms of documentation, logistics reliability, and technical service tend to hold better pricing power than those competing purely on spot rates.
