Core Viewpoint - The Ministry of Commerce and the General Administration of Customs have jointly announced export controls on superhard materials and related items, which may significantly impact domestic producers and overseas downstream customers [2]. Group 1: Export Controls - The export controls include superhard materials such as synthetic diamond powders with an average particle size of less than or equal to 50μm, synthetic diamond single crystals with an average particle size between 50μm and 500μm, and related equipment and technologies [2]. - This announcement expands the scope of previous export controls issued on August 15, 2024, which included certain antimony and superhard material items [2]. Group 2: Industry Significance - Superhard materials, particularly diamonds, are essential in high-end manufacturing and strategic industries, solving complex processing challenges in sectors like aerospace, defense, and electronics [3]. - The potential growth point in the superhard materials industry is functional diamonds for semiconductor applications, with significant market demand anticipated if breakthroughs in diamond substrate technology occur [3]. Group 3: Market Response - On October 10, 2023, A-share superhard material stocks surged, with notable increases such as Sifangda rising by 12.29% and Huanghe Xuanfeng hitting the daily limit [5]. - Several listed companies have disclosed their investments in functional diamond applications, indicating a strong market interest and potential for growth in this sector [7]. Group 4: Company Developments - Guojijiangong has made progress in the MPCVD synthetic diamond sector, achieving small-scale sales of diamond heat sinks and optical window pieces [7]. - Sifangda is working on a project to produce high-quality large-size ultra-pure CVD diamonds, while Huanghe Xuanfeng has developed polycrystalline diamond heat sink pieces with competitive thermal performance [7]. - Statistics show that since July, several superhard material stocks have attracted significant net purchases from leveraged funds, indicating strong investor interest [7][8].

Core Viewpoint - The Ministry of Commerce and the General Administration of Customs of China announced export controls on five categories of materials, including superhard materials and rare earth equipment, highlighting the strategic importance of these materials in the industry [1] Group 1: Export Controls - Export controls have been implemented on superhard materials, rare earth equipment, lithium batteries, and artificial graphite anode materials [1] - The scope of the export controls has expanded compared to those set to take effect in August 2024, indicating a stronger emphasis on the strategic nature of superhard materials [1] Group 2: Industry Impact - Short-term export restrictions may hinder superhard material companies, but long-term effects are expected to accelerate the consolidation of the domestic superhard materials industry [1] - Price fluctuations are anticipated to trend upwards in the future, driven by the consolidation and increased demand for functional applications of synthetic diamonds [1] - There are trading investment opportunities in the superhard materials sector, with a recommendation to focus on leading companies in the industry [1]
