New-mill trust is verifiable process — not retail promo slogans. Shipment lots can align heat/batch IDs, shipping-mark fields, loading photos, and EN 10204 3.1 MTC as ordered. Final documents follow the contracted lot.
- Heat/batch: keep MTC identity aligned with bundle/plate marks when ordered
- Shipping marks: confirm PO, size, heat, destination and handling icons before packing
- Loading evidence: packing/loading photos can be archived for buyer QA or third-party inspectors
