Group 1: Report Industry Investment Rating - No relevant information provided Group 2: Core View of the Report - The rubber market is in a wide - range shock state [1] - The tire market is facing cost pressure and profit shrinkage due to rising raw material prices, and the implementation of price - increase policies faces significant resistance [3][4][5] Group 3: Summary of Related Catalogs 1.

Industry News - As of March 30, more tire companies are raising prices, with an increase of 3 - 5% and most price - increase implementation times concentrated on April 1. Some companies have raised prices through recycling policies, and some have restricted shipments to customers who have completed their purchase tasks. However, the overall product supply is tight, and some companies have obvious shortages, which affects the shipment volume to a certain extent [3][4] - In March, due to geopolitical disturbances, the price of crude oil rose significantly, leading to a general increase in the prices of petrochemical raw materials such as synthetic rubber, carbon black, and additives. Although the upstream price - increase policy has driven the downstream replenishment sentiment to some extent, this round of replenishment is mainly a transfer of inventory from manufacturers to channels. The channel inventory is at a high level, and the release of terminal demand still takes time, resulting in significant resistance to the implementation of the price - increase policy [5] - The raw material costs of tires, including natural rubber, synthetic rubber, carbon black, and additives, have increased this month, and the profit of tire products has further shrunk.

Companies with a large proportion of exports to the Middle East may moderately reduce production [4].
