Tackling Regulatory Challenges: Your Guide to DMF Submission in China
Navigating China’s pharmaceutical market is no easy feat, especially when it comes to API and excipient registration. To sell in China, companies must submit a Drug Master File (DMF) to the National Medical Products Administration (NMPA) — a process known for its regulatory complexities, administrative demands, and language barriers.
Understanding the DMF Process in China
A DMF submission involves more than just sending over a technical file. Foreign manufacturers must appoint a local agent — either a subsidiary or a registered representative — to handle the submission and all related communications with the Centre for Drug Evaluation (CDE) and NMPA.
The main steps include:
- Reviewing the existing DMF for compliance with Chinese guidelines.
- Translating all documentation into Chinese.
- Managing administrative tasks, including registering as an official agent and preparing complete document packages.
- Handling deficiency letters from the CDE and ensuring timely responses.
- Coordinating shipment of required samples and ensuring all additional data requests are met.
Without local expertise, delays, misunderstandings, and compliance failures can easily derail the process.
