📘 Pharmaceutical Manufacturing Certifications
Pharmaceutical manufacturing is one of the most regulated industries in the world, with strict requirements to ensure drug safety, efficacy, and quality. From raw material handling to sterile production, every process must comply with Good Manufacturing Practices (GMP) and international guidelines set by authorities like WHO, FDA, EMA, ISO, USP, and ICH.
This guide provides a comprehensive overview of pharmaceutical certifications and guidelines that every pharma professional, QA/QC specialist, and regulatory compliance manager should know.
1. HVAC Qualification in Pharma
Heating, Ventilation, and Air Conditioning (HVAC) systems play a critical role in sterile and non-sterile pharmaceutical environments. Proper qualification ensures contamination control and compliance with cleanroom classifications.
- ISO 14644 – Cleanroom standards
- WHO TRS 961 – Annex 5 – Commissioning of HVAC systems
- WHO TRS 1010 – Annex 8 – Qualification guidance
- WHO TRS 986 – Annex 2 – GMP compliance in HVAC systems
👉 Importance: HVAC qualification ensures particulate and microbial contamination is controlled, maintaining cleanroom grades (A, B, C, D).
2. Cleaning Validation
Cleaning validation ensures that equipment surfaces are free from active ingredients, residues, and microbes to prevent cross-contamination.
- WHO TRS 1019 – Annex 3
- WHO TRS 1033 – Annex 2 & Annex 4
👉 Importance: This certification is crucial in multi-product facilities where changeovers occur frequently.
3. Equipment Qualification
Pharmaceutical manufacturing equipment must undergo qualification before being used in production.
- WHO TRS 986 – Annex 2
- WHO TRS 961 – Annex 9
- ISO 8573-1 – Compressed air quality
👉 Stages include IQ (Installation Qualification), OQ (Operational Qualification), PQ (Performance Qualification).
4. Compressed Air Validation
Compressed air is often in direct contact with APIs and excipients.
- WHO TRS 986 – Annex 2
👉 Ensures compressed air is free of oil, particulates, and microbial contaminants.
5. Thermal Mapping
Thermal mapping studies temperature distribution in controlled storage areas (warehouses, refrigerators, cleanrooms).
- WHO TRS 961 – Annex 2
- WHO TRS 992 – Annex 5
👉 Ensures uniform storage conditions for raw materials and finished products.
6. Supplier Audits
Supplier qualification ensures raw materials and packaging components are from GMP-compliant sources.
- USP 44, General Chapters
- WHO TRS 937 – Annex 4
- USP Chapter 1083
👉 Reduces the risk of counterfeit or substandard raw materials.
7. Automated System Validation (CSV)
Computerized systems in pharma (ERP, LIMS, eQMS, SCADA, MES) must undergo validation.
- WHO TRS 961 – Annex 7
- WHO TRS 986 – Annex 2
- EU GMP – Annex 11
👉 Ensures data integrity, audit trails, and compliance with 21 CFR Part 11.
8. Personnel System & Training
Personnel must be trained, qualified, and monitored.
- WHO TRS 986 – Annex 2
- WHO TRS 957 – Annex 1
👉 Covers gowning, aseptic practices, and contamination prevention.
9. Premises and Facility Qualification
Facilities must be designed for GMP compliance.
- WHO TRS 957 – Annex 1
- WHO TRS 986 – Annex 2
👉 Includes segregation of sterile vs. non-sterile areas.
10. Good Practices in QC Labs
QC laboratories are audited for compliance.
- WHO TRS 986 – Annex 2
- WHO TRS 957-2010 – Annex 1
👉 Covers sample handling, testing, OOS (Out of Specification) management.
11. Pharmaceutical Quality System (PQS)
A PQS integrates GMP, QMS, and risk management.
- WHO TRS 986 – Annex 2
- WHO TRS 957 – Annex 3
- ICH Q10
12. Self-Inspection & Internal Audits
- WHO TRS 986 – Annex 2
- WHO TRS 961 – Annex 2
👉 Ensures ongoing compliance readiness for regulatory audits.
13. Documentation & Record Management
- WHO TRS 986 – Annex 2
- WHO TRS 957 – Annex 1
👉 Covers BMR (Batch Manufacturing Records), SOPs, logbooks, and eQMS.
14. Good Production Practices (GPP)
- WHO TRS 961 – Annex 5
👉 Covers API, formulations, packaging, labeling, and storage.
15. Sampling & Holding Time Studies
- WHO TRS 992 – Annex 4
- WHO TRS 1019 – Annex 2
👉 Defines sample integrity and stability.
16. Sterile Manufacturing
- Eudralex – Annex 1
👉 Strictly governs aseptic filling, terminal sterilization, isolators, and RABS.
17. GMP Principles & Process Validation
- Eudralex 9 Chapters
- WHO TRS 1019 – Annex 3
👉 Ensures reproducible processes with validated methods.
18. Product Quality Review (PQR) & Annual Product Review (APR)
- 21 CFR 211.180(e) – APR (US FDA)
- EU GMP Volume 4, Chapter 1 – PQR
19. Hazardous Materials & Risk Management
- WHO TRS 957 – Annex 3
- ICH Q9 – Risk management
👉 Focus on cytotoxic, oncology, and high-potent APIs.
20. GDP & GSDP Certifications
- WHO TRS 1025 – Annex 7
- EU GMP – Annex 11
👉 Covers logistics, storage, and distribution integrity.
Pharmaceutical manufacturing certifications are not just regulatory checklists. They form the backbone of product quality, patient safety, and global market compliance.
Companies that strictly follow WHO TRS, FDA, EMA (Eudralex), ISO, and ICH guidelines build trust with regulators and patients worldwide.
Whether it’s HVAC qualification, cleaning validation, sterile manufacturing, or CSV compliance, these certifications ensure a robust pharmaceutical quality system ready for audits and inspections.
