No Australia-Portugal FTA exists, so MFN general tariff rates apply to all Chapter 73 iron and steel articles; a commercial invoice or EUR.1 movement certificate confirming Portuguese non-preferential origin is essential, and structural steel products must carry mill certificates demonstrating AS/NZS 3678 or 3679 compliance before ABF will release the goods.
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.
