It may be a concern for Tier-2, Tier-3 suppliers, but it does not mean that this requirement is not applicable. IATF does not know what is a structure of product we supply. In most cases full risk will be in Tier-1, but sometimes Tier-2 product itself can be used, so both organization has to consider how it should be managed. If external company is picking our "unrendered" scrap, so how do we confirm they render it. There is a documented process required here, so even we persuade it to one auditor as "non-applicable", still we do not meet requirement in other one opinion. It is worth to think about it seriously.
