EU GMP Documentation: Batch Processing and Packaging Records

In short: This guide summarises EU GMP Chapter 4 documentation for manufacturing formulas, processing and packaging instructions, batch records, and supporting procedures. Complete, legible and traceable records help show what happened to each batch and support review, release and recall.

Scope and current source

The European Commission’s current EudraLex Volume 4 index lists Part I Chapter 4, Documentation, as January 2011. This article follows that published chapter and is scoped to EU human medicinal products. The Commission index now lists separate veterinary GMP regulations that took effect on 16 July 2026; readers working with veterinary medicines should use the current veterinary rules rather than assume this chapter is their applicable legal text.

Chapter 4 is guidance for EU GMP documentation. Other jurisdictions may use different terms or requirements. For related reading, see the batch manufacturing record overview, control of documentation and good documentation practice under EudraLex Volume 4.

Document controls

A quality management system should define the documents and record types used, including paper, electronic and hybrid records. Controls should identify the master document, official copies, data handling and record location, and protect record integrity during the retention period. Complex systems should be understood, documented, validated and controlled.

Instruction documents should be approved, signed and dated by authorised people, uniquely identified, clear and linked to an effective date. Procedures and work instructions should use clear, action-oriented wording. Where entries are handwritten, make them legible and indelible. Record actions when they occur; any change should preserve the original information and include a signature and date, with the reason recorded where appropriate (EudraLex Volume 4, Part I, Chapter 4, §§4.1–4.9).

Manufacturing and packaging instructions

An approved manufacturing formula and processing instructions should exist for each product and batch size. Together, these should identify the product, strength and batch size; list materials and quantities; state expected yield limits; and describe the processing location, equipment, preparation, line clearance, step sequence, in-process controls, bulk storage and special precautions (§§4.17–4.18).

Approved packaging instructions should exist for each product, pack size and type. They should identify the product and batch, pack configuration, required packaging materials and their specifications, relevant printed-material examples, line-clearance checks, packaging steps and in-process sampling and acceptance criteria (§4.19).

Batch processing record

Keep a batch processing record for each batch, based on the currently approved formula and processing instructions. EU GMP Chapter 4 §4.20 describes the record content. In practical terms, it should allow a reviewer to trace:

• Product name, batch number, and the dates and times of production and significant stages.
• Who performed and, where appropriate, checked each significant step.
• The identity and actual quantity of each starting material, including any recovered or reprocessed material added.
• Relevant process events and major equipment used.
• In-process controls, results, and the people who performed them.
• Yields at relevant stages.
• Special problems and any authorised deviation from approved instructions.
• Approval by the person responsible for processing.

Where a validated process is continuously monitored and controlled, §4.20 allows automatically generated reports to be limited to compliance summaries and exception or out-of-specification reports.

Batch packaging record

Keep a batch packaging record for each batch or part-batch. Under §4.21, it is based on the approved packaging instructions and should make it possible to review:

• Product name, batch number, and packaging dates and times.
• Operators and, where applicable, the people who checked significant steps.
• Identity checks, conformity with instructions and in-process control results.
• Packaging operations, equipment and line references.
• Samples or examples of printed material, including batch coding and expiry dating, whenever possible.
• Unusual events and authorised deviations.
• The quantities and identifiers of printed components and bulk product issued, used, destroyed or returned, plus the quantity of finished product obtained, so material reconciliation can be assessed.
• Approval by the person responsible for packaging.

Chapter 4 says robust electronic controls may justify not including the listed reconciliation information. That is a conditional provision: the electronic controls and rationale need to support the applicable quality system and records.

Supporting procedures and records

EU GMP Chapter 4 §§4.22–4.28 addresses receipt, storage, sampling, testing, release and distribution records. Receipt records identify the material, supplier and manufacturer, receipt date, manufacturer reference or batch, quantities and containers, the assigned batch number, and relevant comments. Sampling procedures describe the method, equipment, amount and precautions needed to prevent contamination or deterioration. Testing procedures identify methods and equipment, and test execution is recorded.

Written procedures should cover material and product release or rejection, while distribution records should make batch recall possible. Other documented activities include validation and qualification, equipment assembly and calibration, technology transfer, maintenance and cleaning, personnel training, environmental monitoring, pest control, complaints, recalls, returns, change control, deviation investigations, audits and supplier audits (§§4.27–4.29).

Maintain operating procedures for major manufacturing and test equipment. Chapter 4 §4.31 calls for chronological logbook entries, as appropriate, covering use, calibration, maintenance, cleaning or repair, with dates and the identities of people who performed the work. An inventory of quality-system documents should also be maintained (§4.32).

Record retention

For EU batch documentation, retain records for at least 1 year after the expiry date of the respective batch or at least 5 years after Qualified Person certification, whichever is longer (EudraLex Volume 4, Part I, Chapter 4 §4.11). Investigational medicinal product records have a separate minimum tied to completion or formal discontinuation of the last clinical trial. Other legislation or product-specific requirements may require longer periods.

For US records specifically associated with a drug-product batch, 21 CFR §211.180(a) requires at least 1 year after batch expiry. For certain OTC products exempt from expiry dating, the US rule specifies 3 years after distribution. Apply the requirements of the market and product; use longer periods when law or the marketing authorization requires them.

Frequently asked questions

What is the difference between an instruction and a batch record?

Instructions describe the approved process to follow. A batch record documents the actual materials, people, equipment, results, events and decisions for a specific batch.

Can electronic reports replace a batch record?

Not automatically. EU GMP Chapter 4 permits a limited summary and exception-report approach for a validated, continuously monitored and controlled process. The system and reports must still provide suitable control and traceability for the batch.

How long should batch documentation be kept?

Under EU GMP Chapter 4 §4.11, keep it at least 1 year after batch expiry or 5 years after Qualified Person certification, whichever is longer. The US batch-record rule also requires at least 1 year after expiry, with a separate rule for certain expiry-exempt OTC products.
