Batch number and Batch Manufacturing Record are two of the most important parts of pharmaceutical and Ayurvedic manufacturing documentation.
Every medicine, Ayurvedic product, supplement, syrup, tablet, capsule, oil, cream, or other dosage form manufactured in a licensed unit should be traceable from raw material to finished product. This traceability is mainly maintained through the batch number and batch manufacturing record.
A properly maintained batch record helps the manufacturer prove:
What was manufactured
When it was manufactured
Which raw materials were used
Who performed the manufacturing steps
Which machines were used
What quality checks were performed
How much product was produced
Whether the batch passed quality standards
In simple words, a batch number identifies the product batch, and the Batch Manufacturing Record explains the complete history of that batch.
What Is Batch Number?
A batch number is a unique identification number assigned to a specific quantity of product manufactured in one manufacturing cycle.
It helps identify and trace a particular batch from manufacturing to distribution.
A batch number may help track:
Date of manufacturing
Product name
Batch size
Raw materials used
Manufacturing process
Quality control results
Packing details
Expiry details
Distribution details
Complaint or recall history
If any quality complaint arises in the market, the batch number helps identify which batch is involved and where that batch was supplied.
Simple Definition of Batch Number
A batch number is a unique code given to a specific batch of product so that its complete manufacturing, testing, packing, and distribution history can be traced.
Example of Batch Number
Suppose a company manufactures 5,000 bottles of an Ayurvedic liver syrup on 10 August 2026.
The batch number may be written as:
Batch No.: ALS-0826-01
This can be understood as:
ALS = Ayurvedic Liver Syrup
08 = Month of manufacturing
26 = Year of manufacturing
01 = First batch of that month
This is only an example. Every company should follow its own approved Batch Numbering SOP.
What Is Batch Manufacturing Record?
Batch Manufacturing Record, commonly called BMR, is a controlled document that contains the complete manufacturing history of a particular batch.
It records every important step from raw material dispensing to manufacturing, in-process checks, yield calculation, quality control sampling, packing, and batch release.
A BMR is not the same as a Master Formula Record.
The Master Formula Record is the approved standard formula and process for a product.
The Batch Manufacturing Record is the actual record of one specific batch manufactured according to that Master Formula Record.
Simple Definition of BMR
Batch Manufacturing Record is a document that records all manufacturing activities, raw material details, process steps, in-process checks, yield, deviations, and approvals related to one specific batch of a product.

What Is Lot Number?
In many companies, batch number and lot number are used in a similar way. However, technically, a lot may sometimes refer to a specific quantity or subdivision of a batch.
For practical purposes in many pharma and Ayurvedic companies, batch number and lot number both help identify and trace a manufactured quantity of product.
Why Is Batch Number Important?
Batch number is important for:
Product traceability
Quality control
Market complaint investigation
Product recall
Stock management
Expiry tracking
Distribution records
Regulatory inspection
Legal compliance
Customer confidence
Without batch number, it becomes difficult to identify which product was manufactured when and under what conditions.
Why Is BMR Important?
BMR is important because it provides documentary proof that the product was manufactured according to approved process and quality standards.
A BMR helps verify:
Correct raw materials were used
Correct quantities were dispensed
Manufacturing process was followed
Equipment was cleaned and used properly
In-process tests were conducted
Yield was within acceptable limit
Deviations were recorded
Product was approved before release
In pharmaceutical manufacturing, if it is not recorded, it is generally treated as not done.
Contents of Batch Manufacturing Record
A BMR may vary according to dosage form and company procedure, but generally includes the following details:
1. BMR Control Details
This section identifies the document.
It may include:
BMR number
Product name

Permissible yield limits
5. Raw Material Details
This section records every raw material used in the batch.
It may include:
Name of raw material
Grade

11. Yield Calculation
Yield is the quantity of product obtained after manufacturing.
Maintains raw material, packing material, and finished goods movement records.
BMR in Third-Party Manufacturing
In third-party manufacturing, the actual BMR is maintained by the manufacturer because manufacturing is carried out at the manufacturer’s licensed premises.
The marketing company should ask for:
Batch number
Manufacturing date
Expiry date
Certificate of Analysis
Product label specimen
Invoice details
Dispatch details
Testing report, where applicable
For internal records, the marketing company should maintain batch-wise purchase, sale, complaint, and recall details.
Final Thoughts
Batch number and Batch Manufacturing Record are essential for traceability, quality assurance, compliance, and product safety.
A batch number identifies the product batch, while the BMR records the complete manufacturing history of that batch.
Every licensed pharmaceutical and Ayurvedic manufacturer should maintain accurate batch records, follow approved SOPs, record entries at the time of activity, and review BMR before batch release.
Good documentation is not only a regulatory requirement. It is also a strong foundation for quality, trust, and long-term business growth.
