The ratio the schedule implies is the place to start: $20 billion of covered goods [2] against the $451 billion Canada shipped into the United States in 2025 [3] is 4.4% of the flow [5], and a 50% rate on that slice collects roughly $10 billion if volumes hold, which is 2.2% of the total [6], though volumes will not hold. Kent Jones, the Babson economist who wrote the analysis for The Conversation, puts the covered share at about 4% [4] [15], and the gap between his rounding and mine is noise; what matters is that a 50% duty on furniture, textiles and hockey equipment [2] is a quantity instrument dressed as a revenue one, so $10 billion is a ceiling that falls as the tariff does its work.
The number the piece cannot supply, and neither can I, is on the demand side. US spirits came off provincial shelves in Canada and sales plunged, and when Washington asked for that reversed, the provinces' own backlash pushed the concession off the table [12]. Yves Smith, introducing the article, points at the same mechanism in travel: Canadian tourism to upstate New York fell after the Liberation Day round, with hotels and restaurants absorbing it [14]. Duty on imports at least lands in the Treasury; a hotel's lost revenue never reaches anyone's ledger.
This authority shows what the administration is withholding, not what it is offering. Canada came for relief on metals and vehicles, claiming a preliminary deal to take steel and aluminum from 50% to 25% [9], a 25-point cut that would have halved the rate [16]; when Commerce Secretary Howard Lutnick, lobbied by domestic steel and aluminum producers, held that line and withdrew the auto and truck reductions [10], Canada pulled its offer to reopen the Keystone pipeline that Biden cancelled in 2021 [11]. A deal was reportedly very close days earlier [17], but what emerged was a 50% tax on hockey equipment, with the pipeline off the table.
This is probably wrong, but I read the $20 billion as an opening position rather than a calibrated one, because Section 338 as described carries no dollar limit: it lets a president impose 50% duties on his own authority on a finding that another country discriminated against US products, and it sat unused from 1930 until July 2026 [7]. Once used, the constraint on the next list is political rather than statutory. The counter-thesis is respectable, or rather it is the more interesting version of the same fact: the scope is small precisely so it can be lifted inside a week once metals are traded, and $20 billion of furniture is a cheap signal to send. The Depression analogy Jones reaches for cuts against both readings, since the two-thirds collapse in US trade between 1929 and 1932 came out of a global retaliation cascade [8] and this is, so far, two countries taxing each other's whiskey [1] [2]. What would change my read: the covered list growing past $20 billion, or steel and aluminum settling at 25% with Keystone back on the table, in which case the statute was a lever rather than a policy.
