What is a Batch Record?
A batch record is the complete set of Good Manufacturing Practice (GMP) documentation that captures the entire production and control history of a single batch, or lot, of a manufactured product. In pharmaceutical, biotech, and food manufacturing, it’s the documented proof that a batch was made according to approved, validated procedures and actually meets its quality specifications.
Before quality assurance can release or reject a batch, it needs answers to a few essential questions. Which raw material lots were used? Which equipment ran the job? Who performed each step, and who verified it? At what process settings, with what in-process results, and did anything go off-script along the way? A batch record answers all of that. The discipline behind one looks a lot like the rigor of a well-written manufacturing SOP, with one difference: every value gets recorded as it actually happens.
Batch records are a core requirement under FDA 21 CFR Parts 210 - 211, which mandate batch production and control records for every batch a facility makes. Incomplete batch records ranked among the top ten FDA 483 observations in FY2024, and the FDA conducted 989 drug manufacturing inspections that year - a 27 percent increase over FY2023 - making thorough documentation more scrutinized than ever.
Key Characteristics of a Batch Record
- Lot traceability: Links every raw material lot, equipment ID, and process parameter to one specific batch.
- Contemporaneous documentation: Operators record results, signatures, and timestamps as work occurs, not after the fact.
- Built on an approved template: Each record derives from a version-controlled master, keeping production consistent with the validated standard operating procedure.
- QA disposition: Concludes with a documented release or rejection decision before product reaches the market.
Master Batch Record vs. Executed Batch Record
The Master Batch Record (MBR) is the approved, version-controlled “recipe” template: ingredients, target quantities, step-by-step instructions, and acceptance limits, with none of the actual results filled in yet. Changing it isn’t casual. Any change requires formal change control, and the whole thing is governed by 21 CFR 211.186.
The Executed Batch Record (EBR), also called the Batch Manufacturing Record (BMR), is a batch-specific copy of the MBR that gets completed during real production: actual quantities, lot numbers, timestamps, operator signatures, and any deviations. There’s one EBR per batch, governed by 21 CFR 211.188.
| Aspect | Master Batch Record (MBR) | Executed Batch Record (EBR) |
|---|---|---|
| Purpose | Approved instructions and limits | Actual values and event history |
| Content | Blank template, target specs | Real results, signatures, deviations |
| When to use | Defines the validated process | Created for every individual batch |
Batch Record Examples
Example 1: Pharmaceutical tablet production
Picture an operator on the night shift running a tablet batch. Before she touches anything, she pulls the BMR for that product and starts filling it in as she goes: the actual API and excipient lots she weighed out, the granulation and drying parameters she dialed in, the compression machine settings, the in-process hardness and weight results she logged. Every step she performs gets her initials, and every step a second person verifies gets theirs. Months later, if an auditor asks “who made batch 0427 and how do you know it was right?”, the answer isn’t a shrug. It’s that document, ending with QA’s documented decision to release or reject before a single tablet leaves the building.
Example 2: Electronic batch record in supplement manufacturing
Now picture the same kind of work, but on a screen instead of paper. A supplement manufacturer runs an electronic batch record (eBR) system that walks the operator through a nutritional batch one step at a time. Try to skip a step out of order and it won’t let you. Punch in a value that’s out of spec and it blocks the entry instead of quietly letting it slide (which, on paper, happens more often than anyone likes to admit). Equipment data gets captured automatically, and everything stamps into a tamper-evident audit trail that lines up with ALCOA+ data integrity principles and 21 CFR Part 11. The compliance work happens while the work happens, not in a frantic review afterward.
How Glitter AI Helps with Batch Records
Here’s the part nobody warns you about: your eBR system handles the regulated execution layer beautifully, but it doesn’t teach anyone how to actually use it. The know-how for setting up an MBR, navigating the eBR screens, or running a review-by-exception workflow tends to live in one or two people’s heads, and it goes stale the moment a process changes. That’s exactly the gap Glitter AI fills for you. Instead of asking your most experienced QA lead to sit down and write a training manual (which, let’s be honest, rarely happens), they just record themselves doing the work once, and Glitter turns it into a clear, visual step-by-step guide with screenshots and annotations. New quality and production hires get up to speed faster, and everyone follows the same procedure the same way every time. If you want to go deeper, there’s plenty more in our manufacturing SOP best practices guide.

Frequently Asked Questions
What is a batch record?
A batch record is the complete GMP documentation that captures the full production and control history of a single batch of a manufactured product, proving it was made to approved specifications.
What is the difference between a master batch record and an executed batch record?
A master batch record (MBR) is the approved, blank template defining the validated process, while an executed batch record (EBR) is the batch-specific copy filled in with actual results, signatures, and deviations during production.
What is the difference between a batch record and a batch manufacturing record?
They are essentially the same thing. A batch manufacturing record (BMR) is another name for the executed batch record - the completed, batch-specific production document.
What must a batch record contain under 21 CFR 211.188?
It must contain batch and lot identification, materials and quantities used, equipment IDs, step-by-step processing with parameters, in-process and lab results, personnel signatures, deviations, and yield reconciliation.
What is an electronic batch record (EBR)?
An electronic batch record is a digital system that replaces paper records by guiding operators, enforcing limits, auto-capturing data, and creating tamper-evident audit trails to support GMP compliance.
How is an electronic batch record different from a paper batch record?
Paper records are documented and reviewed after the fact, while electronic batch records enforce correct sequence and limits in real time and block out-of-spec entries as work happens.
Who reviews and approves a batch record before release?
Quality assurance reviews the completed batch record against the master batch record and specifications, then makes the documented decision to release or reject the batch.
How does ALCOA+ apply to batch records?
Batch record data must be Attributable, Legible, Contemporaneous, Original, and Accurate - plus Complete, Consistent, Enduring, and Available - to satisfy data integrity expectations.
Is an electronic batch record system required by the FDA?
No. The FDA does not mandate electronic batch records, but they strongly support compliance by reducing human error and enforcing data integrity automatically.
What is review by exception in batch record systems?
Review by exception is an electronic batch record capability where reviewers focus only on flagged deviations and out-of-limit entries rather than checking every value, speeding up batch release.
