CJEU: claiming the wrong tariff quota does not justify double duties

What happens if an importer claims the wrong tariff quota? Can customs charge both safeguard and anti‑dumping duties on the same shipment because of it? A seemingly minor procedural error raised an important question about the interaction between two EU trade defence instruments – and a recent Court of Justice ruling has now drawn the line. This article explains how the mistake arose, what the Court was asked to decide, and the reasoning behind its answer, then sets out what it means in practice for importers and their representatives: the importance of selecting the correct tariff quota order number, monitoring quota availability before declaration, and the potential implications where both anti‑dumping and safeguard duties have been charged. A practical guide for anyone managing trade defence exposure or handling declarations where tariff quotas apply.
