Practical guidance for API registration
Concise, practitioner-oriented notes on how APIs are registered and qualified across major markets — free for formulators, registrants and procurement teams.
CEP (Certificate of Suitability): what it is and why it matters
A CEP certifies that an API's quality is suitably controlled by the European Pharmacopoeia monograph. For EU formulators it can replace a full ASMF review and dramatically shorten qualification.
EDMF / ASMF: the open part and the closed part explained
The EU Active Substance Master File splits into an Applicant's Part (open) and a Restricted Part (closed). Understanding the split is key to smooth API registration in Europe.

ICH Q7: the global GMP guideline for APIs
ICH Q7 is the international good manufacturing practice guideline for active pharmaceutical ingredients. It defines the quality system every serious API maker must run.
US DMF: registering an API with the FDA
A Type II Drug Master File lets an API manufacturer submit confidential manufacturing details to the FDA, which US formulators reference in their own applications.
