Introduction: The global dietary supplement market is projected to reach $230 billion by 2027. For brands looking to capture their share of this growth, China remains the world’s largest manufacturing hub for supplements. However, navigating the Chinese supply chain is fraught with challenges that can make or break your business. This comprehensive guide will walk you through the 7 critical factors that separate successful supplement brands from those that struggle.
I、 GMP Facility Certification – Your First Line of Defense
Good Manufacturing Practice (GMP) certification is non-negotiable for any reputable supplement manufacturer. But here’s what most brands don’t realize: not all GMP certifications are created equal. The certification must cover your specific product type (capsules, tablets, powders, softgels) and be current, not expired.

Key verification steps:
1、Request the certificate directly from the manufacturer
2、Verify through the issuing body’s official website
3、Check that the scope covers your specific product formats
4、Confirm the certificate is current, not expired
II、GMP Facility Certification – Your First Line of Defense

1、What is your actual monthly output for my product format?
2、What are your standard lead times for production runs?
3、How do you handle scalability during peak demand periods?
4、What happens if there are delays?
