What a batch is
A batch is material produced in one run under one set of conditions. Everything in it shares a history, which is what makes a single analysis valid for all of it.
Where it must appear
On the vial label, on the outer box, and on the Certificate of Analysis. All three must agree. A mismatch means either a labelling error or that the certificate belongs to different material — and both are worth resolving before use.
Why identical codes across boxes are expected
A batch number identifies material, not an individual container. Every box filled from one batch carries the same number, so encountering the same code more than once is normal.
What it enables
Traceability in both directions: from a vial back to its production and analysis records, and from a production record forward to everywhere that material went. Without retained records on the manufacturer's side, a batch number is only a string.
