Selection rules

1. Match dosage form first: solid oral, liquid, sterile, topical, or packaging-only. A listed pharmaceutical plant is not automatically qualified for every form.
2. Confirm FDA registration, license, and the last inspection or quality-system evidence the company will share.
3. Ask which operations stay on site versus get contracted, including testing, serialization, and packaging.
4. Require the same batch size, release-test panel, and change-control rules from every shortlisted site.
5. Separate clinical or development capacity from commercial supply. Those are different operating models.
6. Use state pages when the program needs on-site audits, controlled-substance proximity, or a regional packaging node.

How to source this work

Use a pharmaceutical manufacturer when cGMP, FDA registration, dosage form, contamination control, and batch documentation—not general contract manufacturing capacity—are the buying criteria.
