The Empty Truck Tariff

The U.S.-Canada tariff fight is being sold in the usual sovereign register: resolve, leverage, industrial revival, flags doing calisthenics. But North American commerce has an awkward physical property. Goods must travel in both directions, in equipment that does not become patriotic at the border. Canada is scheduled to impose retaliatory duties on Sept. 8 covering $27.6 billion of U.S. exports, matching U.S. tariff rates of up to 50% on targeted Canadian goods. The measures span more than 700 products, from apparel and appliances to steel, dairy, furniture and aluminum. The underlying dispute is here.

That breadth matters because a tariff is not merely a price wedge on a spreadsheet. It changes which supplier gets an order, which warehouse holds inventory, which broker prepares paperwork, and whether a truck crossing south has enough cargo to finance its trip back north. The Canadian Trucking Alliance warns that weaker Canadian exports to the United States could leave Canadian equipment stranded south of the border without return loads. That is not an abstract inefficiency; empty miles still consume drivers, fuel, capital and somebody’s margin. The logistics risk is reported here.

There is a useful corrective to the instant-apocalypse genre, however. Freight Right Global Logistics said that, as of Aug. 26, booking behavior and shipping activity had not materially changed. Supply chains have inertia: contracts remain live, inventories exist, and managers prefer postponing a disruptive decision until someone can prove it is necessary. But inertia is not immunity. It is often simply the interval in which costs collect their paperwork. The article notes both the muted immediate response and the longer-run risks.

Consumers tend to encounter tariffs as a suspiciously expensive appliance or a grocery receipt that has developed a theory of statecraft. The actual transmission is messier. Import duties raise the cost of specific goods; suppliers and retailers decide how much to absorb, pass through or offset elsewhere; then freight, compliance and rerouting costs arrive to make the arithmetic less photogenic. Yale Budget Lab estimates the current U.S. tariff regime costs roughly $1,100 annually per household, with the newer tariffs on Canadian goods adding about $30. These are estimates rather than observed household bills, but they describe the direction of travel with unwelcome clarity. The estimates and their limits are reported here.

Canada faces its own version of the bill. Oxford Economics estimates the latest reciprocal tariffs could lift Canadian consumer prices by 0.3 percentage points in 2027. That may sound modest when delivered in the soothing dialect of percentage points. Yet the point is not that every shelf suddenly becomes a museum exhibit. It is that an economy built around highly integrated continental production now has to price friction into ordinary exchange. USMCA still underpins nearly $2 trillion in annual U.S. goods and services trade across North America; a tariff contest conducted inside that system is less like closing a gate than charging a toll at every internal doorway. The trade scale and price estimate are here.

Businesses are already behaving as though the customs line has become a permanent operating variable. In a July Purolator survey of 348 U.S. and Canadian logistics decision-makers, 51% reported changing shipping routes, 53% changing suppliers and 52% investing in customs practices because of tariff disruption. Survey responses are not a national accounts release, and their methodology is not fully detailed in the report. Still, they capture the corporate instinct accurately: when policy becomes volatile, firms buy optionality, then send the invoice downstream or accept lower returns. Usually some combination of both. The survey findings are reported here.

The advertised purpose of tariffs is often local production. Their early practical effect can be geographic rearrangement. Among the organizations in the Purolator survey, 19 had moved distribution operations and 23 had moved manufacturing to Mexico during the prior 18 months; further moves were planned. Canadian respondents accounted for a substantial share of those shifts. This does not establish that every move was caused by tariffs, nor does it prove Mexico has solved the industrial-policy puzzle. It does show where firms look when a formerly seamless bilateral route acquires a customs tollbooth and an election-cycle mood swing. The reported relocation figures are here.

For consumers, “reshoring” and “nearshoring” are often treated as interchangeable slogans with reassuring hard hats. They are not. Moving warehousing or processing to Canada, as 43% of Canadian companies in the survey said they had done, may reduce exposure to U.S.-based suppliers. Moving distribution or manufacturing to Mexico changes transport lanes, sourcing relationships and investment plans. Neither automatically means a factory has returned to the town featured in the press conference. The reported adjustments by Canadian firms are here.

The durable lesson is not that trade policy cannot alter supply chains. It plainly can. It is that supply chains answer to incentives with more nuance than a campaign slogan permits. They reroute, stockpile, relabel, relocate and occasionally leave a truck waiting for cargo in the wrong country. Brandon Fried of the Airforwarders Association put the institutional remedy more plainly than most tariff theatre manages: “Both governments need to get back around the negotiating table before this dispute escalates further.” Until then, the border will continue doing what borders do best: turning political gestures into line items. The call for negotiations and the freight consequences are here.
