This point of BRC states that the site must test traceability across a group of products, including primary packaging.
So I have contacted our supplier of primary packaging to conduct a trace and they have rejected this, because they are only a wholesaler/distributor and are not willing to give details of their manufactures. the only things they are willing to share are migration reports, specifications and BRC certificate.
My question is where do I stand with this / will the migration reports, specs and BRC certificate suffice?
