How should we view the A-share market performance on April 7, 2025?

Two major events occurred on Monday: U.S.-China trade tariffs and DuPont’s sanctioning. DuPont’s antitrust investigation triggered a butterfly effect in the A-share market: Who is capturing the 'market share cake' of multinational giants? I. The Capital Logic Behind DuPont’s Stock Plunge On the evening of April 4, the State Administration for Market Regulation (SAMR) launched an antitrust investigation into DuPont China, sending shockwaves through the capital markets. By the close of U.S. trading, DuPont’s (DD) stock plummeted 12.75%, wiping out over $10 billion in market value. This event—akin to dropping a boulder into the A-share pond—not only shook the market position of foreign chemical giants but also sent ripples across sectors such as semiconductor materials and environmental technology. From a financial perspective, DuPont China holds a pivotal role in its global operations. In 2024, DuPont China’s semiconductor materials business accounted for 21% of its global revenue, with products including CMP polishing pads and photoresists commanding over 70% domestic market share. The antitrust probe could force a contraction of its core business, while domestic firms are rapidly filling the resulting void via a dual-pronged strategy of 'technological substitution + policy incentives'. II. The 'Domestic Substitution Feast' in Semiconductor Materials 1. CMP Polishing Pads: Dinglong Co., Ltd.’s 'Comeback Story' DuPont’s monopoly in CMP polishing pads directly threatened China’s chip industry security. As the only domestic company mastering the full production process, Dinglong Co., Ltd. (300054) has surpassed 30,000 wafers in monthly sales of polishing pads; its Q3 2024 revenue surged 90% year-on-year. Its Wuhan facility’s annual capacity will expand to 480,000 wafers by 2025, potentially lifting its market share from 10% to 25%. More notably, Dinglong has achieved full self-sufficiency in critical raw materials—including prepolymers and microspheres—effectively breaking DuPont’s supply-chain blockade. 2. Photoresists: Jingrui Electronic Materials and Nanjing University Optoelectronics’ 'Dual-Leader Rivalry' DuPont’s extensive patent portfolio in photoresists once severely constrained domestic players. Jingrui Electronic Materials (300655) has achieved large-scale mass production of i-line photoresists and now supplies top-tier wafer fabs including SMIC and ChangXin Memory; its domestic market share rose to 15% in 2024. Meanwhile, Nanjing University Optoelectronics (300346) developed ArF photoresists supported by China’s National Integrated Circuit Industry Investment Fund—the first domestically produced high-end photoresist to pass customer validation. With expanded capacity coming online in 2025, it aims to capture 10% of the market. 3. Semiconductor Packaging Materials: Qingyun New Materials’ Path to Becoming an 'Invisible Champion' Unlisted Qingyun New Materials’ flash-spinning ultra-material Kunlun™ has already replaced DuPont’s Tyvek® in medical packaging, capturing 12% of the global market. Its Nantong facility boasts 15,000 tons of annual capacity, and its 2024 revenue exceeded RMB 1 billion, making it the world’s second-largest supplier after DuPont. Holding 56 core patents, this 'unicorn' enterprise is challenging DuPont’s dominance in semiconductor packaging materials. III. 'Ecosystem Restructuring' in Environmental Technology 1. Water Treatment Technology: Beijing OriginWater’s 'Membrane-Based Breakthrough' DuPont’s long-standing monopoly in China’s water treatment market is being challenged amid growing concerns over PFAS contamination.

Raw material prices rose by 40%; DuPont reversed course and raised its full-year targets—what justifies specialty plastics’ pricing power?

Facing this situation, DuPont’s response was direct: it fully passed on approximately $90 million in incremental costs to downstream customers via surcharges and price hikes—expected to be fully implemented starting in Q2. CFO Antonella Franzen explicitly stated on the earnings call that about 1% of DuPont’s full-year organic growth would stem from pricing actions, entirely offsetting rising input costs. Notably, this is not ordinary 'demand-driven inflation', but rather a deeper mechanism of risk-cost reallocation—when the entire cost structure faces uncertainty, large materials suppliers redistribute risk through commercial terms, and the direction of redistribution flows downstream. What does this mean for downstream procurement? Going forward, material quotations will increasingly feature 'temporary surcharges', 'energy surcharges', 'logistics surcharges', and 'raw-material volatility adjustments'. The traditional procurement model—based on quarterly or annual fixed-price contracts—is giving way to more flexible, dynamic pricing mechanisms. This trend is especially pronounced in the specialty materials sector. Specialty Plastics: Structural Advantages Amid Cost Shocks Not all materials companies possess such pricing confidence. DuPont’s ability to raise prices rests on a crucial premise: it sells specialty—not commodity—materials. Looking at DuPont’s Q1 segment performance: its Healthcare & Water Technologies segment posted net sales growth of 5.6% to $806 million, driven strongly by medical packaging and biopharmaceutical markets; its Multi-Industrial segment saw sales rise 3% to $875 million, underpinned by robust aerospace and automotive demand. Both segments share a key trait: customers prioritize performance, certification, and supply stability far more than price sensitivity. Source: DuPont This stands in stark contrast to commodity chemical producers. Standardized general-purpose materials—such as PE and PP—face abundant alternatives; customers can easily switch suppliers, meaning price hikes risk losing orders. Specialty materials operate under the opposite logic: once certified and embedded in a customer’s supply chain, switching entails prohibitively high costs—granting suppliers inherent pricing leverage. In April, DuPont also sold its aramid business to Arclin for $1.8 billion, further sharpening its portfolio toward higher-value, higher-margin, and more resilient businesses. This divestiture—coinciding with its pricing strategy—signals DuPont’s clear understanding: in an era of volatile costs, corporate resilience hinges on where you sit along the value chain. The 'Moat' Behind Specialty Plastics Specialty materials’ pricing power is fundamentally a structural advantage, rooted in three core pillars. First, certification barriers. Certification cycles for materials used in healthcare, aviation, semiconductors, and new energy often span one to three years—or longer. Once a given material passes end-product validation, customers rarely switch—because doing so means repeating the entire certification process, incurring massive time and R&D costs. Second, irreplaceable performance. Consider several common specialty engineering plastics in the plasticization industry: PEEK’s (polyether ether ketone) exceptional heat resistance, chemical corrosion resistance, and mechanical strength; LCP’s (liquid crystal polymer) outstanding dielectric properties and dimensional stability; PVDF’s ultra-high purity and corrosion resistance—none of these materials have economically viable commodity substitutes in extreme application environments.
