What is Master Batch Record (MBR)?
A Master Batch Record is the definitive, approved recipe and process guide for manufacturing a specific product consistently every time. It specifies exact quantities of raw materials and components, the precise sequence of process steps, and the quality checks that must be performed, so that every batch produced has the same properties and characteristics.
The MBR must go through formal review and approval by the quality unit before it can be used, since it becomes the standard every future batch record is measured against. Any subsequent change to the formula or process requires a formal change to the approved MBR, not just an informal adjustment on the production floor.
Once approved, the MBR serves as the template from which a batch-specific Electronic Batch Record, or EBR, is generated for each actual production run, with the EBR documenting the real-time execution of that specific batch against the MBR's standardized instructions.
Why is Master Batch Record (MBR) important?
The MBR is what makes consistent, repeatable manufacturing possible at scale, ensuring that a product made today has the same quality and characteristics as the same product made months or years earlier.
Because the MBR is the foundation every batch record is built from, keeping it accurate and current is essential; an outdated or incorrect MBR would propagate errors into every subsequent batch produced from it.
Regulatory frameworks including GMP and ICH Q7 specifically require master production instructions like the MBR, reflecting how central this document is to demonstrating consistent, compliant manufacturing.
How does Master Batch Record (MBR) work?
A typical Master Batch Record process includes:
- Development. Draft the formula, process steps and quality checks for the product.
- Review and approval. Route the MBR to the quality unit for formal approval.
- Version control. Maintain the MBR as a controlled document with a defined revision history.
- Batch generation. Generate a batch-specific EBR from the approved MBR for each production run.
- Change control. Route any proposed formula or process changes through formal approval before updating the MBR.
- Periodic review. Reassess the MBR periodically to confirm it remains accurate and effective.
Master Batch Record vs. Electronic Batch Record
| Comparison | Master Batch Record | Electronic Batch Record |
|---|---|---|
| Nature | Approved, standardized template | Batch-specific executed record |
| Changes | Updated through formal change control | Reflects what actually happened for one batch |
Real-world examples of Master Batch Record (MBR)
A pharmaceutical manufacturer's quality unit formally approves a new MBR for a product before the first commercial batch is produced, establishing the standardized reference for all future runs.
A food manufacturer updates its MBR after a formulation change is approved through change control, ensuring every subsequent batch reflects the new, correct recipe.
A contract manufacturer generates a batch-specific EBR from its client's approved MBR for each production run, capturing the real-time execution details unique to that batch.
Regulations and standards related to Master Batch Record (MBR)
ICH Q7 specifies requirements for the production, control and documentation of active pharmaceutical ingredients, mandating the creation of master production instructions such as the MBR alongside executed batch records.
GMP regulations broadly require standardized master production and control records, and ICH Q10 emphasizes documentation, including batch records, as a core element of an effective pharmaceutical quality system throughout the product lifecycle.

Common mistakes with Master Batch Record (MBR)
Common mistakes include allowing informal, undocumented process adjustments on the production floor without updating the approved MBR, creating drift between what is documented and what is actually done.
Other problems include failing to route formula or process changes through formal change control, risking an MBR that no longer reflects a genuinely validated, approved process.
