Summary of Key Points from Conference Call Industry Overview - The conference call discusses the chemical industry, specifically focusing on the supply and pricing dynamics of H acid and active dyes, which are critical intermediates in the dye manufacturing process [1][2]. Core Insights and Arguments - **H Acid Supply Tightness**: Major H acid production facilities, including Dabaidan Leqing Technology Co., Ltd. and Dabaidan Hexin Technology Co., Ltd., have undergone maintenance, leading to a supply shortage. The average market price of H acid increased by 0.63% (+250 CNY/ton) to 40,300 CNY/ton, while the average price of active dyes rose by 4.55% (+1,000 CNY/ton) to 23,000 CNY/ton [1]. - **Environmental and Safety Pressures**: The production of H acid faces significant environmental and safety challenges due to difficult wastewater treatment and hazardous reactions, resulting in the gradual elimination of many small and outdated production capacities [1]. - **Cost Transmission Mechanism**: Historical data indicates that during the 2019 Q1 incident, H acid prices reached 80,000 CNY/ton, causing active dye prices to spike to 33,000 CNY/ton. H acid consumption in active dye production is substantial, accounting for 30-50% of production costs, which facilitates effective cost transmission [2]. - **Production Capacity Concerns**: Current effective H acid production capacity is below 60,000 tons, with a supply gap exceeding 10%. The recent maintenance of two major H acid manufacturers may further reduce effective capacity by over 25% [2]. Potential Investment Opportunities - **Jinji Co., Ltd.**: With an active dye production capacity of 45,000 tons and H acid capacity of 5,000 tons, the company has a market capitalization of approximately 4.3 billion CNY. A 10,000 CNY/ton increase in active dye prices could contribute an estimated 400 million CNY to performance [3]. - **Runtu Co., Ltd.**: The company has an active dye production capacity of 100,000 tons and a disperse dye capacity of 118,000 tons, with a market capitalization of around 13.6 billion CNY. A 10,000 CNY/ton increase in active dye prices could yield an estimated 880 million CNY in performance [3]. - **Zhejiang Longsheng**: This company possesses 70,000 tons of active dye capacity and 140,000 tons of disperse dye capacity, along with H acid and related reductants. A 10,000 CNY/ton increase in active dye prices could lead to an estimated 620 million CNY in performance [3]. Additional Important Information - The ongoing environmental inspections and incidents, such as the fire at the Yadong Fine Chemical Plant in Inner Mongolia, may exacerbate supply pressures for H acid, further impacting the active dye market [2].
