The updated CADIFA Manual for Administrative Procedures by ANVISA was published in February 2025 and is available in Portuguese and English on the agency’s website.

First introduced in August 2020, this manual outlines the requirements for “Active Pharmaceutical Ingredient” (API) dossiers. The DIFA holder must submit an API dossier (DIFA) to obtain a CADIFA (Letter of Suitability), confirming regulatory compliance. Both a valid CADIFA and a GMP certificate are required for marketing authorization or post-approval changes.
