The Qualified Person (QP) & EU Batch Certification
How the European Qualified Person certifies batches for the medicinal market, what Thai exporters should pre-build in batch folders, analytical packages, and impurity narratives before QP review.
Every batch placed on the European Union medicinal market under the human medicines framework must be supported by Qualified Person (QP) certification appropriate to the product class and import pathway. The QP is not a cosmetic signature—they personally attest that manufacturing and testing occurred in accordance with EU GMP and the marketing authorization (or equivalent framework for unlicensed specials where applicable). Thai exporters succeed when they stop imagining the QP as a distant bureaucrat and instead design batch folders that make QP review boringly straightforward.
Disclaimer: QP obligations are EU-side. Your job as origin is to supply complete, consistent, verifiable evidence. Never substitute this article for importer legal advice.
What “QP-ready” documentation looks like
A complete batch manufacturing narrative spans from starting materials (your herbal substance) through processing, packaging, labelling (as applicable), and QC release at the EU site if further processing occurs. Gaps in Thailand-origin sections force the QP to assume risk or block release.
The analytical package should align with monograph-style thinking where invoked: identity, assay, impurities, microbial, and foreign matter—each tied to validated methods or justified alternates.
Impurity and microbiological narratives should explain not just pass/fail but trend, upstream controls, and specification rationale linked to patient safety.
Anatomy of a batch folder (origin section)
- Cover index with batch ID, manufacturing dates, quantity, storage conditions during hold
- Bill of materials tied to approved suppliers and COAs for inputs (where applicable)
- Master batch record execution with signatures, timestamps, in-process results
- Equipment log excerpts for critical steps (dryers, blenders)
- Deviation and investigation packets (even “minor” ones)
- Lab package with chain of custody, methods, raw chromatograms or data as contractually required
- Release authorization at origin prior to export
- Packing list alignment to actual seals and counts
Partnering note: importer and contract manufacturer structures
Many EU importers and contract manufacturers provide QP services as part of their technical package. That does not reduce your origin obligation—it concentrates scrutiny on your Thailand batch records. Operators who arrive with inspector-grade folders shorten technical transfer from months to weeks.
Governance: who requests what from whom
Publish an RACI (responsible, accountable, consulted, informed) for batch folder assembly:
- Thai QA accountable for completeness at release
- EU QP accountable for EU certification decision
- Regulatory affairs consulted on label and classification changes
- Logistics informed before any repack that touches batch identity
Batch record hygiene that QPs praise
- Page numbering and version control on every controlled form
- Cross-references from master batch record fields to annexed COAs
- Clear reconciliation of labels printed, used, and destroyed
- Deviation narratives that state impact assessment and final disposition in one place
- No handwritten corrections without initials, date, and reason—prefer controlled electronic systems
- Consistent time zone notation on timestamps when teams span continents
Analytical storytelling for complex cannabis matrices
Full-spectrum flower has hundreds of analytes in trace amounts. QP teams still expect rational subset testing justified by risk and regulatory precedent in the target member state. Document why each panel item exists and what happens if a non-spec result appears—retest rules, sampling error checks, investigation triggers.
OOS (out-of-specification) preparedness
- Predefined investigation tree (lab error vs. process vs. sampling)
- Quarantine hold rules until disposition
- Customer notification timelines in quality agreement
- CAPA linkage when trend suggests drift, not one-off noise
QP review meetings: how to run them efficiently
Send pre-read index 48 hours ahead. Highlight novelties (first SKU, new supplier, process limit change). Never surprise a QP with undisclosed reprocessing on export day.
Long-term relationship management with EU QP teams
Quarterly quality reviews should include trending COA parameters, customer complaints (even if zero), change control log, and CAPA aging. Transparency on Thailand-side challenges builds trust faster than polished silence until failure.
FAQ
Can a Thai site have its own EU QP?
Usually no in the practical sense—QP functions are tied to EU manufacturing authorization structures. Your path is to support the EU QP with complete data.
What is the #1 reason QP release stalls?
Missing or conflicting batch ID linkage between Thailand and EU relabeling steps. Fix ID mapping in your technical agreement.
How much stability data do QPs expect?
Depends on product, packaging, and claims. At minimum, show you have a stability program with protocols, chambers, and early trending—even if long-term data is still maturing.
Should we translate records to English?
Yes for EU review, with certified translations where your importer requires them. Bilingual master data reduces interpretation errors.
What role does the QP play versus the RP (Responsible Person)?
They are different roles in the EU regulatory landscape; your importer will map which person covers batch certification vs. pharmacovigilance vs. regulatory correspondence. Do not conflate them in export paperwork.
How do we train staff for QP expectations?
Run mock QP reviews internally: a QA lead pretends to reject any record missing signatures, dates, or test references. Gamify first-time-right documentation.
What if the QP requests raw instrument data?
Expect it for flagship batches or disputes. Archive data in tamper-evident repositories with audit trails where possible.
How do we handle split processing between Thailand and EU?
Define transfer testing and ownership of intermediate hold times. QP will ask whether Thailand release was final or conditional.
Should batch records mention equipment calibration due dates?
Yes where equipment is critical. Expired calibration is an automatic finding in many audits.
What about subcontract labs in third countries?
Importer may require audit rights or accreditation evidence. Document subcontract scope and data ownership clearly.
Can marketing attend QP meetings?
Usually not helpful unless discussing label claims only. Keep commercial pressure away from release decisions.
How fast should we respond to QP queries?
Define SLA in agreement (e.g., 48h for routine, 24h for safety-adjacent). Missed SLAs compound distrust.
What is a “technical agreement” minimum attachment list?
Specs, audit cadence, change notification, OOS rules, recall roles, data retention, confidentiality, subcontractor approval process.
