North American CDMO Manufacturing
North America is the largest pharmaceutical market by revenue and home to hundreds of contract manufacturers. The US alone has over 500 FDA-registered drug manufacturing facilities. For US-based sponsors, domestic CDMOs reduce supply chain risk, simplify regulatory interactions, and shorten shipping timelines for temperature-sensitive biologics.
The BIOSECURE Act is reshaping outsourcing decisions. Companies that previously relied on certain Chinese CDMOs are actively reshoring manufacturing to North American and European partners. This has tightened capacity in biologics and cell therapy manufacturing, making early CDMO engagement more important than ever.
Where are the manufacturing clusters? The Boston-Cambridge corridor leads in biologics and cell therapy. The Research Triangle (NC) has strong small molecule and drug product capacity. San Francisco and San Diego anchor West Coast biologics. Canada offers competitive pricing through federal SR&ED tax credits, with hubs in Montreal and Toronto.

Frequently Asked Questions
Why choose a North American CDMO?+
Proximity to the FDA simplifies regulatory interactions and inspections. Shorter supply chains reduce risk for temperature-sensitive products. Time zone alignment improves project communication. For US-market products, domestic manufacturing avoids import complexities and potential trade disruptions. The BIOSECURE Act may also require US government-funded programs to use non-restricted CDMOs.
How does the BIOSECURE Act affect CDMO selection?+
The BIOSECURE Act restricts US government agencies from contracting with companies that use certain foreign biotechnology companies of concern for manufacturing. While primarily targeting government-funded work, it signals broader supply chain decoupling. Pharma and biotech companies are proactively shifting manufacturing to North American and European CDMOs to avoid future restrictions and supply disruptions.
