NCTS depends on an EORI number and guarantee data tied to transit volumes. Intrastat depends on commodity codes and statistical values that must match your customs declarations exactly, since Revenue and the CSO cross-check them.</p> <h2> The Practical Problem </h2> <p>Managing these as three separate data entry points means the same fields get typed in multiple times, by different people, in different systems. That's where mismatches happen: a commodity code entered slightly differently in an Intrastat return versus a customs declaration, or a guarantee reference that doesn't update when an MRN is discharged late.</p> <p>The mechanics of each system, including thresholds, deadlines and guarantee types, are detailed in the full <a href="https://www.icustoms.ai/blogs/aeo-status-ireland-ncts-intrastat-reporting-guide/" rel="noopener noreferrer">AEO, NCTS and Intrastat compliance guide</a>.</p> <h2> A Single Source of Truth Approach </h2> <p>Structuring these as one data workflow, where AIS declaration data feeds both NCTS and Intrastat automatically, removes the duplicate entry and keeps everything traceable back to one record. That's the approach iCustoms takes with its iNCTS and iAIS integration.</p> <p><a href="https://www.icustoms.ai/book-a-demo/" rel="noopener noreferrer">Watch a demo</a> of the connected data workflow:</p> ai customscompliance ireland aeo
