Alcoa and Rio Tinto redirect Canadian primary aluminum to customers outside the US after the 50% tariff
Alcoa 'redirected certain Canadian production to customers outside the U.S.' in Q2 2025; about 30% of its Canadian output is available for spot sales; historically about 70% of its Canadian metal went to the US; its Canada-to-US tariff cost was about US$20m in Q1 and US$115m in Q2 2025 (10-Q Q2 2025). Rio Tinto: shipping destinations 'flexed'; its US-destination shipments fell from 723 kt (H1 2025) to 630 kt (H2 2025) and 585 kt (H1 2026), with tariff costs of US$321m, US$709m and US$773m (US$1.03bn in 2025); the Midwest duty-paid premium averaged US$855, 1,731 and 2,406/t, which Rio says came to fully compensate the 50% tariff. Quebec HS 7601 exports to the Netherlands reached 63 kt in June 2025.

Claims that rest on this event
- Europe is a real but small diversification channel, made of defence and resources. The binding items are Canada's agreement to join the EU's SAFE defence-procurement programme, the CPTPP trade pact now in force with the UK, Uniper's LNG contract and Germany's purchase of Lockheed Martin Canada's CMS 330 combat system; the rest (EU associate membership, the German submarine choice, SEFE's LNG deal) is non-binding. Canadian aluminum hit by US tariffs also went to the Netherlands and Italy in 2025. The EU took about 5.8% of Canada's goods exports in January-July 2026.
Alcoa and Rio Tinto redirected Canadian aluminum to customers outside the US after the 50% tariff: the companies' own filings behind the shift to Europe.
How it bears on the outcome
| Explanation | Fit | Why |
|---|---|---|
| O0 No meaningful speed-up | Neutral weak | Company redirection concerns destination, not the pace of the build-out. |
| O1 Faster, but the extra output goes mostly elsewhere | Fits moderate | Alcoa and Rio Tinto redirected Canadian metal outside the US and US-bound shipments fell, consistent with output going to other buyers. |
| O2 Faster, and more volume reaches the US (this level or higher) | Against weak | Falling US-destination shipments are awkward for rising US volume, but the Midwest premium now offsets the tariff, so flows could return. |
| O3 Locked-in preferential terms for the US | Against weak | Producers paying over US$1B a year in tariffs shows no preferential US terms in force. |
