Deploy a shared, verified tariff schedule that all member states reference, eliminating disputes about which tariff rate applies to a given product. Cerulea Studio assembles it from Compliance Attestations, Provenance Notary, and Audit Logs, anchoring the agreed schedule as a single verified reference every customs authority uses.
Turn divergent national tariff applications into one shared, verified schedule every member state customs authority reads.
01.
Fix the agreed rates. The Provenance Notary anchors the agreed tariff schedule as a single verified reference, so member states apply one shared source rather than divergent copies.
02.
Bind rate to product code. Each tariff line ties a rate to a product classification, so customs authorities resolve the correct rate for a given product unambiguously.
03.
Align every state. Because all authorities read the same schedule, the rate applied to a product is consistent across member states, cutting trader disputes.
04.
Track schedule changes. Each amendment is anchored with its provenance, so authorities always reference the correct version and history is auditable.
05.
Catch divergence. A rate applied that does not match the shared schedule is flagged, surfacing inconsistent application for resolution.
06.
Give a verifiable source. Audit Logs let traders and authorities confirm which rate the agreement specifies, resolving disputes against the ledger.
Follow a single tariff line from shared anchoring through consistent application to a flagged discrepancy.

Cerulea decomposes tariff verification into modular contracts. Each layer anchors, resolves, amends, and flags so every member state applies one agreed schedule.
A shared tariff schedule is a horizontal capability. Here is how different actors put the tariff ledger to work.
Apply one agreed rate per product from a shared schedule, ending the inconsistent tariff application that generates trader disputes across member states.
Key Asset Types
Maintain and amend the agreed schedule with version provenance, so every authority references the correct, current tariff at once.
Key Asset Types
Confirm the rate the agreement specifies for a product from a verifiable source, resolving disputes over applied tariffs against the ledger.
Key Asset Types
Whether you are bridging legacy national customs tariff systems or serving traders through a lookup portal, Cerulea routes both into one shared tariff schedule ledger.
For national customs and secretariat systems. Schedule and application events are translated into anchored on-chain tariff records through the API gateway automatically.

Building a tariff verification network with a shared schedule, product-rate binding, and discrepancy detection from scratch requires specialised engineers and long integration cycles. Calculate your exact deployment speed using Cerulea.

The legacy timeline reflects trade agreement integration benchmarks. Wiring national customs systems, building a shared schedule, and shipping discrepancy detection for an average tariff 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 schedule and application rules into pre-audited WebAssembly binaries and provisions the shared tariff ledger instantly.
