Key Players
Competitive Landscape
Producers in the polyamide 6 market include integrated chemical groups, resin compounders and fibre makers. BASF, AdvanSix and DSM Engineering Materials hold the largest shares, followed by Lanxess, Ube and Domo Chemicals. Toray, Asahi Kasei, RadiciGroup, Grupa Azoty, Formosa Chemicals & Fibre, Shenma Industrial and EMS-Chemie complete the list of key players. Strict circular economy targets, low-carbon production rules and closed-loop recycling are expected to increase competition during the forecast period.
During 2025 and 2026, producers faced cost and supply shocks. Chinese caprolactam producers agreed a 20% output cut in November 2025.[1] Envalior raised caprolactam and PA6 resin prices in March 2026.[7] China Risun started a caprolactam-to-hexamethylenediamine plant in May 2026, and Leuna-Polyamid moved towards shutdown in September 2026.[4][8] These developments show that caprolactam access and cost pass-through will remain important factors for company participation.
Company developments mapped to drivers, trends and opportunities (2026-2036)
| Development | Driver | Trend | Opportunity |
|---|---|---|---|
| September 2026: Leuna-Polyamid received no binding offers and moved towards a controlled shutdown. | Weak demand, high energy prices and resin imports were cited in the Domo insolvency. | German caprolactam and polyamide 6 capacity is falling. | Producers with caprolactam units elsewhere may serve displaced converters. |
| August 2026: EU duties of 60% to 67.6% on Chinese polyamide yarn were reported in effect. | Imports of Chinese yarn reached 21,183 tonnes in the investigation period. | Yarn trade flows into the EU are being reset. | Fibre makers outside the duty range may gain EU supply contracts. |
| May 2026: China Risun started a 50,000 ton caprolactam-to-hexamethylenediamine plant. | The plant extends a caprolactam chain of 810,000 tons a year. | Chains link benzene, caprolactam and HMDA. | Integrated chains may supply nylon intermediates. |
| March 2026: Envalior raised prices by EUR 550 a tonne on caprolactam and PA6 base resins. | Geopolitical developments raised upstream product and energy costs. | Producers are passing raw material costs to converters. | Long-term supply contracts may limit exposure to price steps. |

AdvanSix and Ube hold owned caprolactam and polymer positions, but the companies differ by region, feedstock route and exposure to plant reductions. Envalior and China Risun act through cost pass-through and chain extension. The German plants of Domo Chemicals are due to shut down.
Who leads the polyamide 6 market?
Estimated company shares place BASF at 20% to 24%, AdvanSix at 15% to 19%, DSM Engineering Materials at 12% to 16%, Lanxess at 9% to 13%, Ube at 7% to 11% and Domo Chemicals at 6% to 10%. Other companies together hold 18% to 26%. Position in the market follows caprolactam access, polymerisation scale and cost pass-through.
Which producers have documented caprolactam positions?
AdvanSix makes caprolactam at Hopewell and polymerises a share into nylon 6 resin at Chesterfield.[2] The Spanish subsidiary of UBE produces caprolactam and nylon polymers.[6] China Risun operates a caprolactam chain of 810,000 tons a year.[4] Envalior supplies Akulon and Durethan PA6 resins.[7]
What should buyers evaluate before approving a supplier?
Converters require caprolactam origin, polymer grade consistency, delivery reliability and price pass-through terms before approving a supplier. Owned or contracted caprolactam supply and technical support after plant changes are also expected to influence supplier selection. Suppliers with stable feedstock and clear pricing terms receive higher preference.
How is competition expected to change through 2036?
Competition is expected to increase among producers with secure caprolactam, closed-loop recycling and low-carbon production. Plant closures and import duties may restrict supply from some regions. However, backward integration, chemical recycling and bio-based caprolactam open growth opportunities through 2036.
