Mill Certificate Traceability
with EPC PO Matching

EN 10204 is the European standard for material certificates. 3.1 is a mill certificate issued by the manufacturer's quality department, validated by an authorised representative independent of production. 3.2 adds a third-party inspection (e.g. by TÜV, Lloyd's, DNV) and is required for safety-critical applications, IBR-scoped pressure equipment, and most O&G EPC procurement above defined size / pressure thresholds. Pathnovo extracts and validates both, flags 3.1 used where 3.2 is required, and tracks third-party inspector identity per cert.

Every PO line item carries a tag, a material grade, a size, and an order quantity. Every mill cert carries heat number, material grade, size, and shipped quantity. Pathnovo cross-references heat to PO using a multi-attribute match (grade + size + quantity + delivery date). Where heat is not on the PO line directly, the upstream supplier shipping document (mill packing list, bill of lading) bridges the gap. Output: every PO line item linked to one or more heat numbers with quantity rollup, and every cert linked to the PO line(s) it supplies.

A heat number is the unique identifier of a single batch of molten steel poured into a casting or forging. Every plate, pipe, fitting, and bar from that heat shares the same chemistry and mechanical properties certified once on a single mill cert. Heat traceability matters because regulatory codes (ASME, IBR, PED, NACE) require provenance from heat to installed component. Without heat traceability, no IBR registration, no PESO certification, no safety case for sour service, no forensic investigation. The pressure-equipment industry runs on heat numbers; without a structured register, every project is exposed.

Yes for any IBR-scoped pressure equipment in India (boilers, pressure vessels, piping above IBR thresholds). Yes for ASME Boiler & Pressure Vessel Code-stamped equipment globally. Yes for PED (European pressure equipment directive) Category I and above. Yes for NACE MR-0175 sour service applications in the petrochemical and oil & gas industries. Yes for any project with EN 10204 3.2 specified procurement requirements. The mill cert register is also typically a contractual handover deliverable from EPC to owner-operator. Pathnovo automates the workflow that is otherwise done manually in spreadsheets.

GoSmarter and Certivo serve metals manufacturers and distributors: they extract mill certs at the producer side. They do not handle EPC PO matching, IBR Form IV registers, PESO compliance, or multi-vendor reconciliation. Pathnovo is built for the EPC + owner-operator side: matching incoming mill certs to issued POs, generating gap reports before inspection, and producing the regulatory views that Indian and ASME-scope projects require. Different industry, different output, different workflow.

Pathnovo handles them natively. The training corpus includes mill certs from Chinese steel mills (Baowu, Ansteel, HBIS), Korean producers (POSCO, Hyundai, Seah), Japanese mills (Nippon Steel, JFE, Kobe Steel), Indian (SAIL, Tata, JSW, Jindal), German (TKS, Salzgitter), French (Vallourec), Russian (TMK, ChelPipe), and Middle Eastern producers. Translation is automatic; ASTM / EN / JIS / GB / IS material grade equivalences are built in. Output is in English with original-language source citations.

Mill certificate processing is included on every paid tier of the credit-based pricing model. Each certificate page consumes 2 credits, so a typical 100-200 certificate batch fits comfortably inside Starter (₹40,000/$1,200 per month, 1,000 credits). Larger batches (5,000+ certs) sit on Professional or Scale. Indian PSU rate-card compatibility available. Free 14-day trial with 100 credits to validate up to 50 certs before any commitment.

IBR Form IV is the material identification record required for every IBR-registered pressure-equipment item in India. It captures heat number, chemistry, mechanical properties, and certification chain. Pathnovo extracts every IBR-scoped cert, validates against IBR chemistry / mechanical requirements, and auto-populates Form IV per item. The output integrates with /compliance/ibr for IBR registration, IBR welder qualification (Form VIII), and Chief Inspector of Boilers stamping workflows.
