High price volatility – Many vendors quote USD > 250 per gram without clear cost breakdown, eroding your R&D budget.
Inconsistent purity – Batch‑to‑batch variations (≥ 98% vs. 99.5%) cause assay failures, leading to costly repeat experiments.
Slow logistics – Ocean freight from China often exceeds 45 days; air freight spikes to USD 5 per kg, inflating total landed cost.
Regulatory uncertainty – Lack of GMP, FDA, or ISO certifications can stall import clearance, risking project timelines.
Limited customization – OEM/ODM requests are rejected or delayed, forcing you to source from multiple suppliers.
Data point: A 2025 survey of 312 US biotech firms reported a **37 % increase** in project overruns directly linked to API supply issues.
