Hi Anika ,
Yes , you are right .
COA is for product , and it is batch specific ,so it is for each batch or lot not only once .
it is required in 9.2,9.3 ISO 22002-1
In this case we have different systems ,no inter-company supply will not help since system is not integrated or unified between different plants , you are like different plants with different schemes , you should follow ( BRC 220.127.116.11 and 18.104.22.168) and 9.2,9.3 ISO 22002-1
So I think if you need ( according to BRC 7 and FSCC ) :
- Copy of the GFSI certificate .
-COA sent with each batch.
-A successful site audit which as a minimum covers product safety, traceability, HACCP and good manufacturing processes. This audit must be completed by an appropriately experienced and
