The link to documentation
A batch (or lot) code identifies a specific production run of a material. Because documentation such as a certificate of analysis is batch-specific, the code is what connects the vial in your hand to the correct records. Without it, a certificate cannot be matched with confidence.
Traceability in practice
Recording the batch code when you receive and label a material means you can always trace it back to its documentation. This is the practical basis of traceability from receipt through to use.
What to do if it’s missing
If a batch reference is missing or does not match, treat that as a reason to pause and query before proceeding. Documentation and material should agree.
Frequently asked questions
What’s the difference between a batch and a lot?
The terms are often used interchangeably; both identify a specific production run.
Why record the batch code on receipt?
So the material can always be matched to its batch-specific documentation later.
