1. Report Industry Investment Rating No relevant content provided. 2. Core View of the Report The report comprehensively analyzes the PTA, MEG, and downstream polyester industries, covering their basic knowledge, production, trade, and market conditions. It highlights the high concentration of PTA and MEG production in Asia, especially in China, and the significant growth in domestic production capacity in recent years. The report also discusses the trade patterns, profit situations, and market trends of these industries [12][24][43]. 3. Summary by Directory PTA Basics - Definition and Market Introduction: PTA, or purified terephthalic acid, was the first chemical futures variety listed in China in December 2006. It is a raw material for polyester with end - uses mainly in textile, clothing, and soft drinks [12]. - Storage and Transportation: Mainly stored in packaging bags at East China's main port terminals, with storage areas along the Yangtze River, Hangzhou Bay, and Xiamen. Transportation is mainly by sea and inland waterways, with some short - distance transportation by road [14]. - Industry Chain: Produced from crude oil via PX, it is mainly used to produce polyester (PET). One ton of PET requires 0.855 tons of PTA and 0.332 tons of MEG. About 70% of PTA is used for polyester fibers, 24% for bottle - grade polyester, and the rest for film - grade polyester [19][20]. - Production Capacity: Global PTA capacity is mainly in Asia (nearly 90%), with China accounting for over 78% of Asia's capacity. As of November 2025, China's effective PTA capacity reached 9471.5 million tons [24]. - Capacity Distribution: Regionally concentrated in Jiangsu and Zhejiang, with private enterprises being the main suppliers. Yisheng and Hengli account for 41% of the total capacity [27][28]. - Import and Export: China's PTA imports have decreased from 2.74 million tons in 2013 to 18,000 tons in 2024, while exports reached 4.42 million tons in 2024, mainly to other Asian regions and Russia [31]. - Profit Situation: From 2016 - 2019, the industry had high profits due to limited new capacity and downstream recovery. From 2020 - 2024, private large - scale refineries' concentrated production led to compressed processing fees and the elimination of some high - cost small - scale plants [36]. - Trading Patterns: Include long - term contracts (referencing CCF's daily average price with appropriate premiums/discounts), spot trading (futures + price - fixing), and derivative pricing methods (futures price - fixing + monthly/weekly average basis) [38]. MEG Basics - Definition and Application: Ethylene glycol (MEG) is an important petrochemical raw material, mainly used in polyester production. Globally, about 85% of MEG is used in polyester, while in China, over 93% is used in polyester [43]. - Production Process: The main synthesis routes are the ethylene route (including petroleum ethylene, ethane ethylene, and MTO ethylene methods) and the oxalate route. The ethylene method is the global mainstream, while China mainly uses the petroleum ethylene method and the coal - to - ethylene glycol oxalate method [50][51]. - Profitability of Different Processes: Coal - to - MEG's profit has improved significantly this year, with higher operating loads. Ethylene - based MEG has been operating below the break - even point, but losses have narrowed compared to the previous two years [54]. - Production Capacity Development: China's MEG production capacity has reached 30.075 million tons, with ethylene - based capacity accounting for about 64% and coal - based capacity accounting for 36% [58][62]. - Production Distribution: Ethylene - based plants are mainly in Zhejiang, Jiangsu, and Liaoning, while coal - based plants are in Shaanxi, Xinjiang, and Inner Mongolia [62]. - Import and Export: MEG imports peaked in 2020 and have since declined. In 2024, the import dependence dropped to 25%, with the main import sources being Saudi Arabia, Canada, and the United States [65]. Downstream Polyester Basics - PTA/MEG's Downstream Products: The main downstream demand for PTA/MEG is polyester, which is used in textile, clothing, beverages, and film products. Filament has the largest share in polyester, followed by short - fiber and bottle - chips [69]. - Short - Fiber Basics: Polyester short - fiber is made from PTA and MEG. Its trade pattern is mainly from east to west and bidirectional north - south. The main production and sales areas are Jiangsu, Fujian, and Zhejiang, with transportation mainly by road, water, and rail [71][76][77]. - Short - Fiber Industry Chain: It is produced from crude oil via PTA and MEG, with end - uses in filling, non - woven, and spinning. In 2024, spinning accounted for 64% of direct - spun polyester short - fiber production [79]. - Short - Fiber Production Capacity Distribution: Concentrated in Jiangsu and Zhejiang. In recent years, short - fiber exports have increased significantly, with 1.318 million tons exported in 2024, a 9.4% increase year - on - year, and 1.255 million tons exported from January - September 2025, a 31% increase year - on - year [83][88]. - Polyester Bottle - Chips Basics: Made from PTA and MEG, used mainly for packaging. Sales are divided into direct sales (60% - 70%) and distribution (30% - 40%) [91][102]. - Bottle - Chips Production Capacity: Production capacity has increased rapidly, exceeding 20 million tons at the end of 2024, almost doubling since the end of 2022 [105]. - Bottle - Chips Demand: Global demand has been growing steadily, with an average annual growth rate of 6.1% from 2015 - 2024. In 2024, the main downstream consumption areas were soft drinks (39%), exports (42.4%), sheet materials (15.8%), and oil bottles (2.9%) [108]. - Bottle - Chips Export Trade: China is the world's largest net exporter, with exports widely distributed. In 2024, the top five export destinations accounted for only 23% of total exports [112][113].
