Inspection & Test Plan (ITP)
Inspection & Test Plan (ITP)
- Inspection & Test Plan (ITP) can be prepared per order and submitted for buyer review before production release.
- Hold points for dimensional, chemical, mechanical, and packing checks can be aligned with buyer QA.
- Mill Test Certificate EN 10204 3.1 (or project-required equivalent) is prepared against heat/batch traceability.
Third-party inspection coordination

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
