In 2025, a survey of 312 US‑based biotech firms revealed that 38% of ADC development delays are directly linked to the linker supply chain. Below are the most common obstacles you likely face:
- High Price Variability – Competing suppliers quote 20‑40% higher prices for the same purity grade, eroding your budget forecasts.
- Inconsistent Purity – Impurities above 0.5 % trigger re‑validation, extending cycle time by an average of 12 days.
- Slow Delivery – Average lead times of 4‑6 weeks in North America cause missed milestones in clinical‑grade production.
- Expensive Shipping & Customs – Freight charges and duties can add $2,500‑$5,000 per kilogram, especially for bulk orders.
- Regulatory Uncertainty – Lack of CE, FDA, ISO‑9001, and GMP certificates leads to additional audit costs.
Imagine the cost of a single delayed batch: $150,000 in lost R&D time, plus opportunity cost for delayed market entry. Act now to prevent these losses.
