Current GMP under 21 CFR Parts 210 and 211 governs pharmaceutical manufacturing. Cosmetic GMP has historically been voluntary — and is becoming mandatory under MoCRA. Andrew explains the practical…

[upbeat music] Let me start with what GMP actually is, because I think it's one of the most consistently misunderstood concepts in manufacturing.
It is not a set of specific rules that once individually satisfied makes you compliant.
It is a quality system philosophy, a framework for managing manufacturing operations in a way that consistently produces products that meet their intended specifications, are safe for their intended use, and can be traced back to every decision made during their manufacturing processes.
The core principles of GMP are actually quite simple, even if the regulatory implementation of those principles are complex.
Every critical step must be documented in a written procedure before it's performed, not reconstructed from memory afterwards.
Second, critical process steps must be validated, meaning you have objective evidence that the process consistently produces a product meeting its specification.
Fourth, appropriate facilities and equipment must be maintained in qualified states.
And fifth, the entire manufacturing process must be documented in real time in batch records that create a complete traceable record of what was done, by whom, with what materials, at what parameters, and with what results.
They sound straightforward, I know, but the difficulty is not in understanding the principles, it's in building and maintaining an operation that consistently lives up to them, batch after batch under the pressure of production schedules, personnel change, equipment variability, and supply chain disruptions.
Now, where GMP gets complicated is in the question of what Defined and controlled means, what validated requires, what qualified entails, and what level of documentation would be considered sufficient.
