March 4 (Reuters) - According to data monitoring, on March 4, the price of adipic acid from Hualu Hengsheng increased, with the ex-factory price reaching 8,700 yuan per ton, a rise of 400 yuan per ton. The price hike is attributed to rising costs, leading to a continuous upward trend in the adipic acid market. Chempricehub analyzed adipic acid, giving a bullish-bearish score of +1. The report highlights that Hualu Hengsheng's ex-factory price for adipic acid increased by 400 yuan per ton to 8,700 yuan per ton, driven by cost pressures, which has sustained the upward momentum. This indicates tight supply in the spot market for adipic acid or rising raw material costs, pushing prices higher and significantly benefiting spot prices. The score of +1 (moderately bullish) reflects the substantial and sustained price increase, though attention should be paid to future cost changes and market supply-demand dynamics to avoid excessive optimism.
