Proclamation 11032: some aluminum and steel derivatives cut to 25%; USMCA-qualifying Canadian derivatives taxed on non-US content only (15% floor); primary aluminum stays at 50%
Proclamation 11032 (91 FR 34087, cl. 2(d)) adjusts the Section 232 metals regimes: certain derivative products drop to 25%, and USMCA-qualifying Canadian and Mexican derivatives pay 25% on their non-US content only, with a 15% floor. Unwrought primary aluminum, Quebec's largest US export, stays at 50%.

Claims that rest on this event
- US tariffs spare raw resources and hit processed goods. Energy was taxed at 10% or exempt in every round, the potash rate was cut to 10%, and the 2026 Section 338 tariffs exempt energy, potash, critical minerals and fish, while steel, aluminum, copper, autos and lumber took the heaviest tariffs.
A 2026 proclamation cuts some aluminum and steel derivatives to 25%, and Canadian ones that qualify under USMCA pay only on their non-US content, while primary aluminum stays at 50%: here the processed good is spared more than the raw metal.
How it bears on the outcome
| Explanation | Fit | Why |
|---|---|---|
| O0 No meaningful speed-up | Neutral weak | A tariff adjustment says little about the pace of the build-out. |
| O1 Faster, but the extra output goes mostly elsewhere | Fits weak | With primary aluminum still at 50%, continued diversion of Quebec metal away from the US is expected. |
| O2 Faster, and more volume reaches the US (this level or higher) | Against weak | The 50% rate on primary aluminum works against more Canadian volume reaching the US; the derivative relief is partial. |
| O3 Locked-in preferential terms for the US | Against weak | A content-based reduction is a tariff adjustment, not a binding supply guarantee or preference for Canadian resources. |
Tested hypotheses: a thought experiment
Suppose Washington foresaw and wanted this. Would this event look any different than under the rival readings? This is a deliberately contrarian test, explained here, not the author’s belief. Judgments, not measurements.
Judged to fit the plain self-interest reading better than the foresight reading. What this means
| Reading | Fit | Why |
|---|---|---|
| I0a Accident Tested hypothesis (intent) | Neutral weak | A technical adjustment to derivative rates fits equally with ad hoc or deliberate policy. |
| I0b Plain self-interest; Canada's response not considered Tested hypothesis (intent) | Fits weak | Easing derivatives, which are costly to US users, while keeping primary aluminum at 50% to protect US smelting is consistent with plain self-interest. |
| I1 Foreseen and welcomed, not the reason Tested hypothesis (intent) | Neutral weak | The adjustment says nothing about foresight of Canada's build-out. |
| I2 Foreseen and wanted (this level or higher) Tested hypothesis (intent) | Against weak | Keeping Quebec's largest US export at 50% is mildly awkward if Canadian supply to the US were a wanted response, though other goals could explain it. |
| I3 Worked-out plan with specific targets Tested hypothesis (intent) | Against weak | No sign of specific Canadian supply targets; primary aluminum remains penalised. |
| R-annex Annexation Rival reading | Against weak | Giving USMCA-qualifying Canadian derivatives a lower rate is mildly awkward for an aim to subordinate Canada. |
| R-frag Fragmentation Rival reading | Neutral weak | Tariff mechanics say nothing about breaking Canada up. |
| R-weaken Weaken-Canada rivals (annexation or fragmentation) Rival reading | Against weak | Partial relief for Canadian derivatives is mildly awkward for a goal of weakening Canada, though primary aluminum stays penalised. |
