SunSirs: China Natural Rubber Market in September first Rose and then Fell

According to the Commodity Market Analysis System of SunSirs, the domestic natural rubber spot market in September first rose and then fell. As of September 30th, the spot rubber market in China's natural rubber market was around 14,666 RMB/ton, a decrease of 1.95% from 14,958 RMB/ton at the beginning of the month and a decrease of 4.86% from the high point of 15,416 RMB/ton during the cycle. As of September 30th, the mainstream price for 24 years of Guangken, Baodao, and Haibao latex in Qingdao area is 14,550-14,850 RMB/ton.

In early September, on the one hand, the downstream tire industry gradually entered the peak season with a slight increase in production, and on the other hand, the domestic and foreign raw material markets remained strong at a high level, providing strong support for natural rubber. In mid to late September, with the weakening of typhoon weather, the supply in foreign markets gradually increased and prices slightly fell. In addition, as the downstream stocking stage came to an end near the end of the month, market transactions were light, and the natural rubber market fell from a high position.

In September, the price of natural rubber raw materials fell slightly from a high level. As of September 30th, the price of Thai glue was 54.80 baht/kg, a decrease of 1.17% compared to 55.45 baht/kg at the beginning of the month. In early September, the main rubber producing areas at home and abroad were affected by rainfall and typhoons, resulting in lower than expected new rubber production and high raw material prices; In mid to late September, with the improvement of weather conditions, the supply of raw materials has been restored, and the high level of natural rubber raw materials has slightly fallen, which has slightly weakened the support for the Tianjin rubber market.

The significant drop in natural rubber inventory in September has provided strong support for the natural rubber market. As of September 28, 2025, the total inventory of Tianjiao bonded and general trade in Qingdao area was 456,500 tons.

The overall stability and slight increase in downstream tire production in September provided strong support for the natural rubber market's essential needs. As of September 28th, the construction of semi steel tires by domestic tire companies has started at around 73%; The construction of all steel tires by tire companies in Shandong Province has slightly increased to around 66%.

The current high prices of natural rubber raw materials have fallen, and the downstream pre holiday stocking stage has ended. However, the overall inventory of Tianjiao Port continues to decline, and it is expected that the natural rubber market will fluctuate narrowly in the later period.
