Summary by Directory 4.1 Futures Market - **Contract行情**: On September 18, 2025, synthetic rubber fluctuated and declined. The BR2511 contract opened at 11,570 yuan/ton, reached a high of 11,590 yuan/ton, a low of 11,355 yuan/ton, and closed at 11,415 yuan/ton, down 205 yuan/ton or 1.76% from the previous trading day's settlement price.

However, trader inventories have increased for four consecutive weeks, and there is still pressure on total social inventory. Butadiene port inventory has dropped to 25,600 tons, but 50,000 tons of shipments are expected to arrive in October, weakening cost - side support [6] - **Policy and market dynamics**: According to data released by the General Administration of Customs on September 18, China's rubber tire exports in August were 870,000 tons, a 2.6% year - on - year increase. The cumulative export volume from January to August was 6.5 million tons, a 5.1% year - on - year increase [6] 4.3 Market Outlook - The Fed's interest rate cut has led to a rebound in the US dollar index, putting pressure on commodities. Although there are disruptions in the natural rubber tapping process due to rainfall and high raw material prices, the spot trading sentiment has weakened. Supply and inventory pressures dominate the market. The short - term synthetic rubber futures market is expected to continue its weak performance, and future price movements need to pay attention to pre - National Day stocking, device maintenance, butadiene prices, and tire production data [7][8]

Core Viewpoint - The article discusses the complexities and ambiguities in the prospectus of Yuan Chuang Co., a company specializing in rubber track products, raising concerns about its production capacity, research and development (R&D) capabilities, and overall transparency in its IPO process [1][12]. Production Capacity - Yuan Chuang Co. claims that after the completion of its fundraising project, its rubber track production capacity will reach 550,000 units, which raises questions since its actual capacity was already 609,300 units at the end of 2022 and is projected to increase to 679,400 units by 2024 [2][3]. - The prospectus does not clearly explain whether the stated 550,000 units is an addition to existing capacity or the total capacity, leading to confusion [3][4]. - The company has been quietly expanding its production capacity over the years, but the lack of clear communication in the prospectus creates ambiguity [5][6]. Environmental Compliance - Concerns are raised regarding the compliance of the company's production with environmental regulations, as it is listed among key monitored units by the local environmental authority, yet no environmental impact assessment documents for the new capacity could be found [7]. Research and Development - The article highlights issues with Yuan Chuang's R&D efforts, noting that the company has only filed 13 patents since 2022, which is fewer than its competitor Jin Li Long [8]. - There are questions about the legitimacy of a named inventor on the patents, as this individual does not appear to be part of the company's staff, raising doubts about the authenticity of its R&D claims [8][9]. - The company has faced criticism for product quality, with significant returns reported and specific complaints from agricultural machinery departments regarding product failures [9][10]. High-tech Enterprise Status - Yuan Chuang claims to be a high-tech enterprise, but the article points out that it does not meet the criteria for such a designation, including insufficient R&D expenditure relative to sales and a lack of qualified technical personnel [10][12]. - The company’s self-identified status as a high-tech enterprise appears to be misleading, as it has not been listed as such since 2016 [10]. Market Positioning - The company aims to list on the main board, which typically favors larger, more established firms, yet its market position in the niche rubber track sector is questioned, especially in comparison to industry giants like Zhongce Rubber [11][12]. - The article suggests that Yuan Chuang's focus on a narrow market segment may not justify its ambitions for a main board listing, raising concerns about its overall viability and transparency [12].
