PVC仓单注销，烧碱主力下游继续提高采购价

1. Report Industry Investment Rating - Not provided in the content 2. Core Viewpoints of the Report - For PVC, geopolitical conflicts lead to increased volatility in the market. Overseas ethylene - based PVC supply is tightened, while domestic ethylene - based enterprises also face raw material supply issues. The demand side is gradually recovering, but the spot supply pressure from the cancellation of March PVC warehouse receipts is large. The cost - side pressure is still being transmitted, and the social inventory pressure has been somewhat alleviated [3]. - For caustic soda, international geopolitical conflicts lead to an expected passive reduction in overseas chlor - alkali plant loads, increasing export inquiries for domestic chlor - alkali products and raising export quotes. The price of 50% caustic soda has weakened, while the 32% caustic soda price has followed the upward trend. The supply - side operating rate has slightly increased, and the demand - side non - aluminum industry has seen an increase in rigid demand procurement, with alumina production showing a slight improvement [3]. 3.
