GMP compliance checklist relevant to compounded supply compounding quality:
- Clean room environment with HEPA filtration
- Environmental monitoring (viable and non-viable)
- Personnel training and competency assessment
- Validated analytical methods for testing
- Stability testing program
- Complete batch records and traceability
- Quality management system with deviation handling

Agreed, and the enforcement dates were staggered by category — 503A first, 503B a few weeks later — because outsourcing facilities have manufactured inventory and clinic contracts to unwind while a 503A makes to order.
