#  Announcing New NIH International Collaborative Project Resources 

 





May 18, 2026

 

 

In September 2025, the NIH released [NOT-OD-25-155](https://grants.nih.gov/grants/guide/notice-files/NOT-OD-25-155.html) establishing a new process for proposals and awards that include NIH-funded international collaborations. Currently, all competing applications that involve an NIH-funded international collaborator must utilize either the PF5 Activity Code for grants or the UF5 Activity Code for cooperative agreements.

[NOT-OD-25-155](https://grants.nih.gov/grants/guide/notice-files/NOT-OD-25-155.html) provides additional information on the new application structure. Funding Opportunity [PA-26-002](https://files.simpler.grants.gov/opportunities/3df028f3-f97a-4cdf-9359-1c6515d091ce/attachments/32095b88-f093-488f-aa71-1b39ce517067/PA-26-002-Full-Announcement.html) outlines application instructions and applicable due dates. Please note that the first applications under the PF5 activity type will be due on May 26th due to the holiday.
