Regulatory and Supply Chain Considerations
- API Market Regulation: API manufacturing is regulated by the FDA (US), EMA (Europe), and respective national agencies. Stringent quality controls are mandatory, especially for antibiotics.
- Global Shortages: Occasional shortages stem from capacity constraints, regulatory delays, or supply chain disruptions. Several suppliers have expanded capacities since 2020.
- Pricing Dynamics: Prices vary based on purity standards, batch size, and regulatory approvals; API costs range from $200-$400 per kg for Chinese producers, while European suppliers often price higher.
