1. Report Industry Investment Rating - Not provided in the content 2. Core Viewpoints of the Report - The inclusion of large - granular urea in the alternative delivery system in Northeast China since 2027 will improve the precision of corporate hedging and reduce logistics and delivery costs [1][9] - The difference in physical properties between large - and small - granular urea leads to different application scenarios, regional adaptability, and industrial chain positions, which in turn affects the price difference between the two [12][13][14] - The price difference between large - and small - granular urea shows seasonal characteristics and is affected by supply - side disturbances and global export structure differentiation [2][30][31] - The technical transformation of urea plants in Jincheng, Shanxi is a systematic upgrade, and the original production capacity is retained, and the impact on the price difference will gradually converge [43][45][50] 3. Summary of Each Section According to the Table of Contents 3.1 Introduction to Large - Granular Urea - Industry Development Trend: The domestic large - granular urea industry has seen steady expansion of production capacity and high - speed growth of output. The proportion of large - granular urea production capacity in the total domestic urea production capacity has increased from 17% in 2021 to 21% in 2025. In 2025, the output reached 14.35 million tons, with a year - on - year increase of 17% [8] - Policy Adjustment: Since February 16, 2027, qualified large - granular urea can be used as an alternative delivery product in Heilongjiang, Jilin, and Liaoning, with a premium of 20 yuan/ton, which is in line with regional consumption characteristics and helps enterprises carry out hedging [1][9] 3.2 Comparison between Large - and Small - Granular Urea - Physical Properties and Application Scenarios: Large - granular urea has a slow dissolution rate, is suitable for mechanized deep application and the production of high - end compound fertilizers, and is mainly demanded in Northeast China. Small - granular urea dissolves quickly, is suitable for top - dressing, flushing, and spraying, and has strong market liquidity [13][14] - Futures Delivery: Small - granular urea is the benchmark delivery product, while large - granular urea can be used as an alternative delivery product in Northeast China starting from the 2703 contract, with a premium of 20 yuan/ton [15] 3.3 Large - Granular Urea Plants - Regional Distribution: North China is the most concentrated area for large - granular urea production capacity in China, accounting for 44% of the national total, with Shanxi accounting for 28% and Inner Mongolia accounting for 14% [16] - Production Process: The mainstream processes of large - granular urea plants are single - stage granulation and two - stage granulation. Two - stage granulation has better product quality, more flexible production conversion, and higher price [20][23] 3.4 Analysis of the Price Difference between Large - and Small - Granular Urea - Seasonal Characteristics: The price difference between large - and small - granular urea is wide in the fourth quarter due to winter fertilizer storage in Northeast China and narrow from June to August after the spring plowing [30] - Influence Factors: The price difference is affected by supply - side production capacity changes and the differentiation of export market preferences. Different regions in the international market have different preferences for large - and small - granular urea [31] - Historical Price Difference Analysis: In different years from 2022 to 2025, the price difference was affected by factors such as export policies, overseas demand, and production capacity maintenance. For example, in 2022, the price difference increased significantly due to the combination of strong export demand and reduced domestic supply of large - granular urea [37][38][39] 3.5 Technical Transformation Analysis of Urea Plants in Jincheng, Shanxi - Reasons for Transformation: Driven by environmental protection policies, Jincheng's urea enterprises are upgrading their coal gasification technology to meet the requirements of clean production [44] - Transformation Plan: Enterprises have chosen two technical routes: micro - pressurized pure - oxygen continuous gasification furnace and crushed/block coal pressurized gasification (Saiding furnace), and adopted the mode of "producing, transforming, and putting into operation simultaneously" [44][45] - Transformation Progress: The technical transformation project has made substantial progress, and the original production capacity has been retained. The impact on the supply of large - granular urea will gradually weaken [48][50]
