1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - This week, there was insufficient positive driving force, and the rebound of rubber prices was limited. The import rubber market had active restocking by early buyers, and factory inquiries were based on rigid demand. The spot offer of domestic natural rubber followed the upward trend of the market, but the downstream buying enthusiasm was average, and the actual transactions in the market were mainly based on rigid demand [6]. - Global natural rubber producing areas are in the tapping season. Continuous rainfall in Yunnan has significantly hindered tapping operations, and the purchase price has remained high and volatile. The weather in Hainan is favorable, and raw material supply has maintained seasonal output. However, the spot market has faced difficulties in price - adding transactions, and some processing plants have become more cautious about high - priced raw materials, with the purchase price of latex stabilizing after rising [6]. - Recently, the total spot inventory at Qingdao ports has been decreasing, with both bonded and general trade warehouses showing inventory reduction. The arrival and warehousing of overseas supplies have remained low, and the overall warehousing rate has decreased month - on - month. The decline in rubber prices has stimulated downstream tire enterprises to replenish inventory at low prices to some extent, and the overall outbound volume has increased month - on - month [6]. - In terms of demand, the capacity utilization rate of domestic tire enterprises has fluctuated slightly this week. Some semi - steel tire enterprises have stopped or reduced production, dragging down the overall capacity utilization rate. Some overhauled all - steel tire enterprises have resumed work and moderately increased production, driving up the overall capacity utilization rate. However, some enterprises have still arranged overhauls, limiting the increase in the overall capacity utilization rate.
