Procurement Strategies and Risk Considerations

Diversification of Suppliers

Relying on multiple suppliers minimizes supply chain disruptions, especially in light of global manufacturing disturbances caused by pandemics or geopolitical issues.

Due Diligence and Validation

Ensuring supplier credibility involves auditing manufacturing practices, reviewing quality documentation, and assessing compliance certificates. Engaging third-party quality assessment agencies can streamline validation.

Pricing and Lead Times

Price competition among Chinese and Indian manufacturers can offer cost benefits. However, lead times might vary based on production capacity and regulatory approval status, necessitating proactive purchasing.

Traceability and Documentation

Comprehensive documentation, including Certificates of Analysis (CoA), Certificates of Compliance (CoC), and stability data, facilitates regulatory adherence and product integrity.
