No Australia-Spain FTA exists so MFN general tariff rates apply to all Chapter 73 iron and steel articles, and importers must verify the Anti-Dumping Commission register before each shipment as transshipment via Spain does not eliminate anti-dumping exposure if goods originate from a country subject to active measures.
Import tip
Always obtain the overseas mill's test certificate tied to the actual heat or batch number of your shipment — not a generic product certificate — because ABF and state building inspectors increasingly cross-reference MTCs against shipment quantities, and a mismatch can trigger a hold or non-conforming product notice that is far more costly than chasing the paperwork upfront.
