U.S. Adipic Acid Technical Grade DEL Houston prices increased by 1.56% during the week ending 22 May 2026, primarily driven by reduced Chinese export availability following maintenance shutdowns at Henan Shenma’s adipic acid facilities. Tightened global spot supply conditions strengthened pricing leverage for domestic U.S. producers and reduced competitive pressure from low-cost imports. Stable downstream demand from nylon, automotive, polyurethane, and engineering plastics sectors supported healthy procurement activity throughout the week. Ongoing freight volatility and tighter replacement economics further reinforced bullish market sentiment. The near-term outlook remains moderately positive as prolonged Chinese production disruptions may continue supporting firm adipic acid pricing across the U.S. market.
Adipic Acid Technical Grade DEL Houston prices in the United States increased by 1.56% during the week ending 22 May 2026, supported by tightening global supply conditions and reduced competitive pressure from Chinese exports. The market strengthened as maintenance shutdowns at major Chinese production facilities constrained international spot availability, allowing domestic U.S. suppliers to implement higher offers amid stable downstream consumption across key industrial sectors.
On the supply side, the primary bullish driver for the U.S. adipic acid market was the reduction in Chinese export availability following production disruptions at Henan Shenma, one of China’s major adipic acid manufacturers. The company shut down its 60,000-ton/year adipic acid facility for maintenance while also initiating a scheduled shutdown at its larger 150,000-ton/year plant, with no confirmed restart timeline announced during the reference week. This significantly reduced Chinese export cargo availability into the global market and tightened spot supply conditions internationally. As Chinese material became less accessible, replacement costs for import-dependent buyers increased, strengthening pricing leverage for domestic U.S. producers. American suppliers consequently revised offers upward to capitalize on reduced overseas competition and firmer import economics. Additionally, ongoing freight volatility and cautious shipping conditions across international trade routes continued to limit aggressive import activity into North America.
Downstream demand for adipic acid on a DEL Houston basis remained stable and constructively supportive throughout the reference week, with procurement activity sustained across all principal consuming sectors. Nylon 6,6 resin producers — the dominant end-use channel — maintained consistent call-off volumes for engineering polymer and textile applications, supported by intact automotive and electrical component manufacturing schedules. Polyurethane intermediate manufacturers sourcing adipic acid-based polyols for flexible foam and elastomer applications reported stable offtake. Automotive and engineering plastics sectors demonstrated measured but reliable procurement against a backdrop of a 17.3-million-unit U.S. SAAR and ongoing lightweighting programme activity. Buyers accepted the 1.56% DEL Houston advance as consistent with the improved supply-demand balance rather than as an opportunistic price push, with no substitution or demand destruction observed during the week.
Looking ahead, the near-term outlook for U.S. adipic acid prices remains moderately bullish as global supply conditions are expected to remain tight until Chinese production normalizes. Market participants anticipate that any prolonged shutdown period at Henan Shenma facilities could continue restricting export volumes and sustaining higher replacement costs for U.S. adipic acid buyers. Stable downstream demand from nylon and polyurethane sectors is also likely to support domestic pricing sentiment through early June. Additionally, persistent freight market volatility and cautious global trade flows may further limit competitive import pressure. However, if Chinese facilities resume operations earlier than expected or global logistics conditions improve significantly, adipic acid pricing momentum may gradually stabilize in the coming weeks.
