We (both this facility and our other global facilities) do not send our inspection/audit reports to customers. The executive committee felt as you do, that it's none of their business. We provide the passing score sheet only.
Pro: I don't have random 2 pallet per year buyers asking to see proof of all abatements from findings and then arguing that even though the certifying body accepted it, they don't, and 'require' me to do X/Y/Z.
Con: I have that same random 2 pallet per year buyer now asking me to complete a 20 EXCEL tab 500+ questionnaire because we don't provide them the report.
I feel it still works out better for us this way, but we're a bit different in that we manufacture HUNDREDS of thousands of pounds per week of product and our most vocal customers are the ones that buy 2-20 pallets per year.
