Trump signs a proclamation changing the list of Canadian goods under the 50% Section 338 tariffs, effective 30 October: 22 tariff lines out (thin hardwood plywood, some paper and plastic packaging, machinery), 100 in (carpets, valves, waste, cocoa powder, thin MDF and other goods)
On 23 October 2026 President Trump signed a proclamation further modifying the Canadian goods covered by the Section 338 duties on motor-vehicle grounds (Proclamation 11048 of 20 July, as amended on 8 September), for goods entered from 12:01 a.m. eastern time on 30 October. Its annex removes 22 tariff lines, among them seaweed, plastic and paper packaging, seven lines of plywood sheets no more than 6 mm thick with a hardwood face, refrigerating equipment and some machinery, and adds 100, among them cocoa powder, paints, shampoos, municipal and clinical waste, vinyl flooring, about 50 carpet lines, thin MDF and other wood products, kraft paper, window air conditioners, valves and canoes. The 50% rate, its stacking on Section 232 duties and its application to goods that qualify under the USMCA do not change, and the alcohol and dairy lists are untouched. Wood products other than lumber stay covered: 66 wood lines after the change, against 64 before. Neither the White House nor Ottawa gave a value for the trade affected.

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.
Non-discriminating: this event fits the plain self-interest reading and the foresight reading equally. It does not tell them apart. What this means
| Reading | Fit | Why |
|---|---|---|
| I0a Accident Tested hypothesis (intent) | Fits weak | A mixed list of product removals and additions, with a senator crediting herself for exemptions for her state's farm products, is consistent with domestic lobbying shaping the tariff list. |
| I0b Plain self-interest; Canada's response not considered Tested hypothesis (intent) | Fits weak | Removing inputs US buyers use (plywood, paper, packing crates) while adding other goods is consistent with plain US self-interest; it fits I1 and I2 equally since nothing in it concerns Canada's build-out response. |
| I1 Foreseen and welcomed, not the reason Tested hypothesis (intent) | Fits weak | Fits equally with I0b and I2: product-level adjustments that serve US buyers say nothing about whether Canada's build-out response was foreseen or welcomed. |
| I2 Foreseen and wanted (this level or higher) Tested hypothesis (intent) | Fits weak | Fits equally with I0b and I1: no resource-sector targeting and no timing tied to a Canadian permitting or building step is observed in the list changes. |
| I3 Worked-out plan with specific targets Tested hypothesis (intent) | Neutral weak | The goods moved on and off the list (plywood, carpets, valves, shampoo) are not named resource projects and show no targeting of a specific build-out. |
| R-annex Annexation Rival reading | Neutral weak | A technical scope change that keeps the 50% rate while easing some goods says nothing either way about absorbing or subordinating Canada. |
| R-frag Fragmentation Rival reading | Neutral weak | The list changes are by product, not by province or region, so nothing in them bears on breaking Canada up. |
| R-weaken Weaken-Canada rivals (annexation or fragmentation) Rival reading | Neutral weak | Partial easing driven by US buyers and constituencies is what you'd expect under most readings and does not single out a weaken-Canada goal. |
