Group 1: Report Industry Investment Rating - Not provided Group 2: Core Views of the Report - The export expectation of PVC has improved, with increased export prices and more new order transaction price increases for ethylene - based PVC. Although there is pressure from spot supply due to the cancellation of export tax rebates and high - level warehouse receipts, factors such as supply contraction, continuous exports, and the recovery of downstream operations have alleviated the inventory pressure. The market sentiment is strong, and the price trend is expected to be oscillating upward [3]. - The export inquiry of domestic chlor - alkali products has increased due to the expected reduction of overseas chlor - alkali plant loads. The price of 50% caustic soda has risen rapidly, and the price of 32% caustic soda has followed. The supply - side operating rate has decreased slightly, and the demand - side has increased rigid procurement. The supply - demand situation of caustic soda has improved month - on - month, and the price trend is expected to be oscillating upward [3].

Core Viewpoints - PVC: After the cancellation of the export tax rebate on April 1st, due to the ongoing geopolitical conflicts, the overseas cracking units have reduced their loads. The supply of raw materials for ethylene - based PVC has tightened, and the export prospects have improved with a sharp rise in export prices. Some domestic ethylene - based enterprises also face raw material supply limitations, with an increasing expectation of load reduction. The profit of calcium carbide - based PVC has improved, and the load may increase. Although the downstream demand is gradually recovering, the social inventory is accumulating, and the inventory pressure in March will be effectively alleviated. The market sentiment has improved, and attention should be paid to geopolitical conflicts, export orders, and enterprise load changes [3] - Caustic Soda: Affected by geopolitical conflicts, overseas chlor - alkali plants may reduce their loads, increasing the domestic export inquiries. The load reduction of domestic ethylene - based PVC enterprises has increased the expectation of load reduction for integrated caustic soda. The supply is slightly increasing, and the demand from non - aluminum industries has increased, but the long - term demand from the aluminum oxide industry is under pressure. The current supply - demand situation has slightly improved, and attention should be paid to export orders, the price trend of 32% caustic soda, and price fluctuations [3] 3.
