YUHAN CDMO
Plant Overview
From development to manufacturing, we bring experience, rigor, and collaboration to every step.
  • icon
    01 / Scale-up
    Seamless scale-up from development
    Our development and manufacturing teams work under one organisation, so processes arrive at the plant already understood. What was learned in the lab carries directly into the first commercial campaign.
  • icon
    02 / Supply
    Reliable supply, campaign after campaign
    Decades of commercial manufacturing have taught us that consistency is the product. Stable yields, disciplined scheduling and continuous process improvement keep your supply predictable over the life of a program.
  • icon
    03 / Quality
    Quality built for global review
    The site operates under cGMP and is approved by major regulatory authorities including the FDA, MFDS and TGA. Client audits and agency inspections are part of how we work, not an exception to it.
  • icon
    04 / Responsibility
    Safe and responsible operations
    Safety and environmental performance are managed with the same rigour as quality. Our commitments through PSCI, the UN Global Compact, Science Based Targets Initiative and Ecovadis hold the site to standards our partners can stand behind.
TRUSTED WORLDWIDE
