Core Insights - The pharmaceutical MNC supply chain has extremely high entry barriers, requiring years for supplier certification through cross-departmental audits in technology, quality, EHS, and compliance. Once included in the qualified supplier list, a strong lock-in effect is formed, making it difficult for new entrants to disrupt the existing supply structure even if they meet technical standards, thus demonstrating a strong first-mover advantage [4][7]. - MNCs demand far more than conventional quality compliance, emphasizing full-process controllability and risk management capabilities. Compliance with guidelines such as EU GMP and ICHQ is required, along with the establishment of traceability systems and safety stock. Any process changes or relocation of production sites must undergo strict and time-consuming certification [4][7]. - In procurement decisions, MNCs are relatively insensitive to price factors, prioritizing the integrity of the supply chain over cost. For MNCs, API costs represent only a small portion of their terminal formulation sales, leading them to pay a premium for stable, traceable, and zero major quality incident supply capabilities, viewing supply chain resilience as a core competitive advantage rather than a cost item. Thus, entering the MNC supply chain often means effectively avoiding "price internalization" [4][7]. - Investment recommendations include innovative drug and device companies such as Furuya Co., Aonlikang, Shutaishen, Weichuang Bio, and others. From the perspective of CXO and raw materials, companies like WuXi AppTec, Jiuzhou Pharmaceutical, Chengda Pharmaceutical, and others are suggested for attention [4][7].
