Industry Overview - Calcium carbide, primarily used for producing acetylene and acetylene-based chemical products, is defined as a key component in organic synthesis [1] - The industry can be categorized into industrial-grade, agricultural-grade, and laboratory-grade calcium carbide based on preparation methods and applications [1] Industry Chain Analysis - The upstream of the calcium carbide industry includes raw materials such as lanthanum, coke, and limestone, while the midstream focuses on calcium carbide manufacturing [2] Industry Development History - The calcium carbide industry in China has evolved from its inception in the late 19th century to a robust sector, with significant technological advancements and challenges such as environmental pollution and overcapacity [5] Policy Background - The industry faces stringent regulations aimed at promoting green development, with policies limiting new capacity and encouraging the use of calcium carbide slag in cement production [9][10] Current Industry Status - China's calcium carbide production capacity decreased and then increased from 2020 to 2023, reaching 41.64 million tons in 2023, a 1% year-on-year growth [14] - The capacity utilization rate was approximately 68.5% in Q4 2023, indicating a relatively low level of operational efficiency [14] - The production volume of calcium carbide exceeded 20 million tons in 2023, with a year-on-year growth rate of 49.1% [15] - The apparent consumption of calcium carbide in 2023 was around 19.55 million tons, reflecting a 46.44% year-on-year increase [17] - The market size of the calcium carbide industry in 2023 was approximately 59.64 billion yuan, showing a recovery trend after a decline from 2018 to 2023 [18] Competitive Landscape - Major domestic producers include ST Zhongtai, Xinjiang Tianye, and Ordos, with ST Zhongtai holding the largest capacity at 2.6 million tons, accounting for 6.2% of national capacity [21] - The Northwest region is the most concentrated area for calcium carbide production, representing 55.1% of total capacity [23] Future Development Outlook - The market size is projected to exceed 61 billion yuan by 2029, with a stable growth rate of 4% annually from 2024 to 2029 [27] - The demand for calcium carbide will be supported by the steady development of the PVC industry and continuous optimization of supply and demand [29]

Group 1 - The electric carbide market is experiencing intense supply and demand dynamics, with prices showing volatility. On June 15, prices in the Wuhai region increased by 50 yuan per ton to 2400 yuan, but just two days later, on June 17, prices fell back to 2350 yuan due to weak price support and supply-demand battles [1] - Starting from June 13, the Inner Mongolia region implemented production limits due to electricity cost pressures, leading to a rapid contraction in supply, which initially supported price increases. However, several manufacturers have resumed production, significantly increasing market supply [2] - The demand side is showing weakness, particularly in the BDO industry, which is facing oversupply issues. It is projected that domestic BDO capacity will exceed 7 million tons by 2025, with utilization rates around 50%, severely limiting BDO's demand for electric carbide [3] Group 2 - The electric carbide market is currently in a phase of increasing supply, with several manufacturers resuming production and some downstream manufacturers undergoing maintenance, which has led to a passive increase in electric carbide supply [2] - There is a noticeable downward price linkage in the electric carbide market, driven by individual manufacturers' pricing strategies and the overall market dynamics. For instance, the Inner Mongolia Junzheng Chemical Company announced a price reduction of 50 yuan, prompting other manufacturers to follow suit [5][6] - The current market is also facing low raw material prices for Lantan, which has limited the cost support for electric carbide prices. The overall market sentiment suggests that the downward price trend may continue until a new equilibrium between supply, demand, and prices is established [7]
