Verify mill certs, COAs, and spec sheets against your standards in seconds
Quality teams sit in a bottleneck of their own making. Every incoming shipment of regulated material — steel, alloys, pharma APIs, food-grade inputs — arrives with a paper trail of mill test certificates and certificates of analysis. The data inside is what determines whether the material gets accepted, rejected, or quarantined. But that data is locked in PDFs of varying layouts, and every shipment needs a human to read it. DocumentIQ extracts chemistry, mechanical properties, lot numbers, and certifications from MTCs and COAs in seconds, then cross-checks against your spec library so the only thing your QC team reviews is exceptions.
The Challenges
Manual MTC and COA review
QC inspectors read PDFs line-by-line, transcribing chemistry results and mechanical properties into spreadsheets. A single shipment takes 15-30 minutes per certificate.
Layout variance across mills
Each producer issues MTCs in their own format. Tabular chemistry in one, prose in another, attached photos in a third. Template-based OCR fails the moment a new mill ships material.
Spec comparison happens too late
The compare-against-spec step usually waits until material is at the dock. If chemistry is out of range, the rework cost is already incurred — sometimes it has already been used in production.
Audit-grade traceability gaps
Regulatory audits demand a defensible chain from received doc → extracted value → acceptance decision. Spreadsheet-based workflows can not produce this without weeks of forensic reconstruction.
How DocumentIQ Solves This
Mill- and lab-specific annotations
Annotate 5-10 MTCs per major producer to teach DocumentIQ the layout. The model generalizes across new revisions and works on photographed/scanned originals.
Automatic spec comparison
Define your acceptance specs once. Every extracted MTC is auto-compared against those specs and flagged green/yellow/red. QC only reviews flagged certificates.
Chemistry + mechanical extraction
Extract element percentages, yield strength, tensile, hardness, elongation — whatever the spec demands. Even when tables span pages or use unit suffixes inconsistently.
Audit-grade evidence chain
Every extracted value links back to the source PDF page and bounding box. Confidence scores are preserved. Auditors get a complete, queryable record of why every shipment was accepted or rejected.
