Batch traceability: why batch numbers matter
Batch traceability means every product carries a unique batch number that points to one production run and its lab report. That lets you trace exactly which batch you received and which CoA belongs to it. RetaEU records the batch number on your order so the link survives after purchase.
- Per batch
- 1 CoA
- On your order
- Batch number
- Failed
- Never sold
One batch, one report
Each production run gets its own batch number and its own CoA. The relationship is one-to-one: the report belongs to that batch and no other.
The reported measurements relate to the stated batch and quantity; they do not automatically apply to other variants.
Why a failed batch is not sold
A failed batch is not sold. The public register shows only published reports; a failed result does not mean its report is public.
From order to CoA
The shipped batch number is recorded on your order. Later you can look that number up and find the exact CoA that belongs to your delivery.
