Chain-of-Custody Proof
Low-Cost Datalogging
GDP-compliant chain-of-custody documentation generated from logger data at the destination. Provides tamper-proof temperature records with timestamps and signed compliance reports for regulatory export documentation and trade lane verification.
GDP Chain-of-Custody Documentation
Pharmaceutical exporters and wholesalers must prove that the temperature chain was maintained by every party who held a shipment — not just their own warehouse — to satisfy GDP requirements and respond to regulatory inspections or importer audits. Without a continuous, signed record tied to each physical handover, any party in the chain can dispute responsibility for an excursion. This offering converts raw logger data into signed, legally defensible chain-of-custody documentation.
How it's deployed
Logger data uploaded at the destination is processed through the Seemoto compliance engine, which cross-references device timestamps against pre-registered handover events to map temperature history to each custodian leg. Digital signatures from each custodian are captured at the point of handover using a web-based confirmation workflow that requires no app installation.
Evidence & Reporting
The output is a GDP Annex-compliant chain-of-custody report with individual signed sections for each custodian, a complete timestamped temperature graph, and an excursion table identifying which custodian held the shipment during any out-of-specification period. Reports are stored immutably in the Seemoto audit vault and exportable as a digitally signed PDF for submission to national competent authorities or trade lane verification bodies.

Frequently Asked Questions
The system records the handover event with or without the counterparty signature, and the shipper's own confirmation timestamp is preserved as a primary record. A non-signature flag is visible in the final report, which places the burden of proof on the refusing party and gives the shipper a documented record that the handover request was made.
A standard excursion report shows when and how far temperature went out of range; a chain-of-custody report additionally maps each temperature segment to the named party responsible at that time. This is the critical distinction required by GDP Chapter 9 for trade lane documentation and enables you to pursue claims against the correct entity.
Yes — the reports are formatted to align with the documentation expectations of EU GDP guidelines and include all mandatory fields: product reference, shipper and consignee details, custodian signatures, temperature record with calibration reference, and excursion log. They can be submitted directly as annexes to inspection responses.
