Preparing for a GMP audit: complete checklist for cosmetic laboratories
A GMP (Good Manufacturing Practices) audit can happen at any time — whether triggered by a competent authority, a distributor client or your quality manager. The best preparation is to have nothing to prepare: meaning operating in a compliant manner every day. Here is the complete checklist to assess and strengthen your compliance level.
1Documentation: your first line of defense
Auditors systematically start with documentation. Verify that you have an up-to-date Cosmetic Product Safety Report (CPSR) for every marketed product, that your manufacturing procedures are documented and approved, that your raw material and finished product specifications are formalized, and that your production forms are completed without unjustified corrections. Any correction must be crossed out with a single line, initialed and dated — never erased or covered.
2Batch records: traceability in practice
Randomly select 3 to 5 recent batch records and check for each: the presence of all raw material batch numbers used, consistency between theoretical and actually weighed quantities, presence of in-process control results, operator and quality manager signatures on each critical step, and the batch release status (released or blocked with justification). This is the exercise the auditor will perform.
3Managing non-conformities and complaints
An experienced GMP auditor knows that a laboratory with no recorded non-conformities is either perfect (unlikely) or not detecting its problems (concerning). Show your non-conformity register with associated corrective actions, your customer complaint handling procedure, and your periodic management or quality reviews. The ability to detect, record and correct problems is the hallmark of a mature quality system.
4Personnel training
Every operator in contact with products or raw materials must have traceable training in GMP, manufacturing procedures and hygiene. Verify that you have signed training records for each member of the production team, that qualifications for critical workstations are documented, and that periodic refresher training is planned. The auditor may directly question an operator about GMP — training must be real, not just documented.
5Premises, equipment and hygiene
Walk through your production premises with an external eye: are clean and dirty areas clearly separated? Is equipment cleaned with cleaning records up to date? Are storage temperatures recorded? Is pest control being monitored? Are work clothes appropriate and consistently worn? These elements, often overlooked in daily operations, are systematically checked during an on-site audit.
6Cosmetiqa to stay audit-ready at all times
Cosmetiqa's goal is to keep teams audit-ready without extra effort. Every manufacturing order automatically generates a complete batch record with timestamps, raw material batch numbers, actual quantities and validations. Non-conformity tracking, quality controls and batch release management are all integrated. Whether the audit is announced or unannounced, you can present any batch record within seconds — no need to search through binders or gather scattered files.
