 "title": "What Can a Mill Test Certificate Prove for a Steel Digital Product Passport?",
 "description": "What a steel mill test certificate can establish, what multi-heat and date fields do not prove, and where current melt-and-pour rules use MTC evidence.",
 "territory": "dpp",
 "category": "iron-steel",
 "direct_answer": "A mill test certificate is useful only at the scope its identifiers and rows actually support. Where the certificate and the relevant row are correctly bound to a heat, batch, product or item, it can establish substantial governed data. Where that binding is missing, the right answer is to keep the value at the scope the document supports or leave the downstream field unresolved.",
