Build a verified rules-of-origin certificate showing a product qualifies for preferential tariff treatment, with the underlying production data anchored for audit. The Provenance Notary, Compliance Attestations, and Traceability Ledger modules carry the core, anchoring production and sourcing data so certifying authorities issue on evidence and importing customs can trust the certification.
Turn unverifiable origin claims into certificates backed by anchored production and sourcing data.
01.
Anchor the inputs. The Traceability Ledger records the origin of each input, so the local and imported content of a product is verifiable rather than asserted.
02.
Compute the qualifying value. Local content is calculated from anchored sourcing data against the agreement's threshold, so qualification is provable.
03.
Certify on data. The certifying authority issues the rules-of-origin certificate from anchored production data, replacing certificates based on unretained records.
04.
Keep the basis. The Provenance Notary anchors the production data used to determine origin, so the certificate can be audited long after issuance.
05.
Clear at destination. Customs in the importing country verify the certificate and its underlying data, granting preferential treatment with confidence.
06.
Deter false claims. Because origin rests on anchored data, a false local-content claim is detectable, protecting the preference regime from abuse.
Follow a single product from sourcing provenance through local-content calculation to a verified origin certificate.

Cerulea decomposes origin certification into modular contracts. Each layer anchors, calculates, certifies, and verifies so a preference rests on auditable evidence.
Evidence-based origin certification is a horizontal capability. Here is how different actors put the certification ledger to work.
Issue rules-of-origin certificates from anchored production data, replacing certification based on records exporters may not retain in an auditable form.
Key Asset Types
Prove local content with verifiable sourcing data, earning preferential tariff treatment and passing audits without reconstructing production records.
Key Asset Types
Verify origin certificates and their underlying data, granting preference with confidence and detecting false local-content claims.
Key Asset Types
Whether you are bridging legacy certificate-of-origin systems or capturing sourcing from exporter ERP, Cerulea routes both into one evidence-based origin ledger.
For certificate-of-origin and chamber systems. Sourcing and certificate events are translated into anchored on-chain records through the API gateway automatically.

Origin Certification Ledger
For exporters anchoring sourcing. A signed connector records each product's sourcing data from the exporter ERP and routes it directly to the ledger.

Evidence-Based Origin Record
Building an origin certification network with sourcing provenance, content calculation, and evidence-based certificates from scratch requires specialised engineers and long integration cycles. Calculate your exact deployment speed using Cerulea.

The legacy timeline reflects trade certification integration benchmarks. Wiring exporter ERP, building content calculation, and shipping evidence-based certification for an average origin network takes a baseline of 8 months. Building the same architecture on Cerulea takes a baseline of 2 weeks, because Cerulea Studio visually translates your sourcing and content rules into pre-audited WebAssembly binaries and provisions the shared origin ledger instantly.
