1. Report Industry Investment Rating - No information provided 2. Core Viewpoints - The global natural rubber production areas are in the tapping season. In the Yunnan production area, rainfall disruptions still exist, and with strong purchasing demand from processing plants, raw material prices remain firm. In the Hainan production area, the weather is favorable for tapping operations, and raw materials are being produced normally. Although Typhoon "Hikaa" is approaching, local processing plants are not actively competing for raw materials due to average orders and profit margins.
