EXPLAINER: Trump bans 0.3% of Canadian imports, the weight of a warning

Neither tariff nor quota

Tuesday, 12:01 in the morning

The United States will not add a tariff to Canadian whisky, whey or molasses: it will exclude them from its territory on Tuesday, September 29, at 12:01 a.m.

A Windsor distillery has already put its American growth on hold, CBC showed on September 11. It is looking overseas. Somewhere, someone is redoing the winter orders. With one market fewer. Quietly.

The Congressional Research Service ran the numbers. The products hit by the three bans accounted for about 0.3% of American imports from Canada in 2025.

Three-tenths of one percent. That is the weight.

While the American sugar lobby has been demanding higher tariffs on foreign sugar for months, Washington slips Canadian molasses onto the list.

What has been in place since August

This is not a tariff. The 50% tariff has hit these products since August 22.

This is not a quota. No volume is allowed.

This is not a time-limited measure. The proclamation gives no end date.

This is not a measure that weighs on the Canadian economy. Experts cited by CBC consider it negligible at the national scale.

This is not an accident either. A senior White House official told CBC as much: the ban targets something other than volume.

It is a warning. It has addressees.

Not one more weight, one more warning.

A law from 1930

Never cited before July

The legal verb is to exclude. Not to tax. To exclude.

It comes from Section 338 of the U.S. Tariff Act of 1930, the one known as Smoot-Hawley, CBC recalled on September 8.

According to the Congressional Research Service, it is the first time a president has expressly cited that section to impose tariffs. That was on July 20.

The section sets a ceiling of 50%. It also provides for exclusion, if the targeted country has maintained or increased its discrimination.

Two floors. The second one has just opened.

An old law, a rare move

Jonathan Doh teaches international business at Villanova University. According to The Associated Press, he considers import bans extremely unusual. He cannot recall an outright ban in the modern era.

The U.S. International Trade Commission also has a role under that section. On September 4, it asked the public how to exercise it, the Congressional Research Service reports.

Rare, then. And dated.

A law nearly a century old. An institution looking for its user manual. A ban that takes effect on Tuesday.

Old law, rare move, chosen target.

A complaint about cheese

Cheese quotas

Read the so-called dairy proclamation. It opens with a complaint.

On July 20, Donald Trump writes, he concluded that Canada discriminates against American commerce through the way it allocates its tariff-rate quotas on American cheeses of all types.

According to the Congressional Research Service, the precise grievance concerns allocations to retailers: denied under CUSMA, granted for cheese under Canada’s agreement with the European Union.

Cheeses. Retailers. Quotas.

Three products, no cheese

Then comes the list of exclusions. According to EY, which summarized the five proclamations on September 9, it covers whey and modified whey, molasses and non-alcoholic beer.

There is whey, a by-product of cheese. There is molasses, a by-product of sugar. There is non-alcoholic beer, which has nothing dairy about it.

Cheese, the subject of the complaint, is not banned. According to EY, cheeses were instead added to the 50% list on September 15. Taxed. Not excluded.

Three products. Zero cheese.

Why does non-alcoholic beer appear in a proclamation about milk?

Cheese in the complaint, not on the list.

0.3%

Two counts

Back to the number.

According to the CRS, the United States imported about US$967 million of the targeted products in 2025. The Associated Press, citing American trade data, counts US$846.1 million.

According to the CRS, that is about 0.3% of everything the United States buys from Canada.

Two methods. The same order of magnitude. Less than a billion.

Derek Holt heads capital markets economics at Scotiabank. On September 9, he wrote that these bans would be negligible. Canada ships very few dairy products south. Alcohol weighs more. About $1.2 billion last year, CBC specifies.

Billions announced

On September 8, a senior official told reporters the ban would affect Canadian goods on the order of a few billion, CBC reported.

A few billion announced. Less than one billion counted.

According to the CRS, the administration itself argues that its tariffs cover a small share of bilateral trade. It adds that the size of the American economy shields it from Canadian moves.

Too little to weigh, enough to deter.

The calculation is there. It is simple.

This explainer says the September 29 ban is first of all a warning: too small to change a trade balance, chosen to make the next retaliation costly.

Less than a billion, and that is the whole calculation.

Deterrence, they say

Canada and the others

The key sentence in the file is unsigned. It is in no proclamation. It comes from a senior official, reported by CBC on September 27.

The bans, according to that official and trade experts, are designed to discourage any further retaliation by Canada and by the other countries targeted by the administration’s economic policy.

By Canada. And by the others.

So the addressee goes beyond Ottawa. Read here. Read elsewhere.

The shelf precedent

On September 8, a senior official explained to CBC why a ban was chosen over a tariff. Provinces had pulled American alcohol from their stores. Canada, he said, set that precedent.

Barry Appleton, of New York Law School, sees it as a way to needle Canada. Washington wants to turn up the pressure a little, he tells CBC.

In other words, the measure is aimed at retaliation, not at trade.

Ottawa reads the warning, and so do other capitals.

Shelves first

Saskatchewan, August 27

Alcohol has its own proclamation, and its own complaint. Same method.

In it, the White House accuses Canada of banning the purchase, distribution or sale of American alcohol, without targeting alcohol from other countries.

It cites a dated example. On August 27, Saskatchewan, one of the two provinces that had not banned American alcohol, announced a 50% surtax starting September 8.

Shelf for shelf. According to The Associated Press, Jonathan Doh sees it as tit for tat.

Half of all spirits

For distillers here, the number is nothing like 0.3%.

About half of the $2 billion in spirits produced each year in Canada is sold in the United States, according to Cal Bricker of Spirits Canada, cited by CBC.

Half. Not three-tenths.

A national number smooths things out. An industry counts in halves.

The clink of bottles being put away, the box taped shut with one pull: in a warehouse, half a market makes a sound.

For Washington, one line; for a distiller, half.

Bulk whisky spared

More than four litres

One detail in the proclamations says more than the speeches. It is measured in litres.

On September 15, according to EY, bulk whisky and liqueurs, in containers larger than four litres, came off the list of products taxed at 50%.

On the 29th, bottled whisky will be banned. Some lines are targeted, EY specifies, only in consumer packaging.

In bulk, Canadian whisky gets through more easily than in August. In the bottle, it no longer gets through.

The liquid, yes. The label, no.

A calibration, says Greer

U.S. Trade Representative Jamieson Greer described the package as “targeted import bans” combined with “a calibration” of the tariffs, according to EY.

Targeted. Calibrated. Both words are accurate.

Who benefits from Canadian whisky in bulk?

The Canadian brand leaves the shelf. The contents can still cross the border.

The bottle is punished, the contents get through.

Negligible, so what

Good news, says Holt

The other reading deserves its full strength. It holds up.

For Derek Holt, these moves serve to save face for the American administration. They are not substantial, he writes, and that is good news.

He is right about the weight. He is right to say the move protects first the image of the one who signs it.

I admit this reading bothers me. It is more reassuring than mine, and I have no number to refute it.

The 50% was already doing the job

An Ontario producer told CBC as much. Matt Johnston, of the Collective Arts brewery in Hamilton, believes that with a 50% tariff, selling to the United States had already become extremely difficult.

For many businesses, the ban would not change much. The tariff was already as good as a moratorium, according to that producer.

That is true, and it does not change the reading: if the ban adds almost no weight, it is because it is not meant to weigh. Its weight lies elsewhere.

And yet a warning has an address. It lands somewhere.

Nothing more to weigh, everything to deter.

Windsor’s whey

A protein in short supply

Whey is a by-product of cheese. It is used to add protein to other foods.

Demand has exploded. So have prices. According to CBC, it has caused shortages of food-grade whey protein and pushed prices to record highs.

Nearly half of the $73 million in whey and modified whey imported by the United States last year came from Canada, according to American data cited by CBC. The eight targeted types make up only a fraction of that.

At the eleventh hour

Dan Crosby runs BioSteel Sports Nutrition, in Windsor. He sells to professional teams and athletes.

So many resources, so much money and time spent adapting, he told CBC, and all of it pulled back at the eleventh hour.

Pulled back. At the last minute.

The scoop in the tub. The powder sticking to your fingers. It is a gym gesture, north and south of the border.

And yet whey is not the subject of the complaint. Cheese is.

In the middle of a shortage, Washington cuts off a supplier.

The molasses that no longer comes

A flow projected at zero

I admit the molasses made me smile at first. Then I read the file.

American sugar producers accuse Canadian refineries of importing a mix of raw sugar, molasses and water, passed off as pure molasses, to get around tariffs and quotas, CBC reports.

On its website, Sugaright, a division of a Connecticut refiner, wrote in August about “closing the spigot completely.”

The spigot. The word is theirs.

The affair goes back to the 1990s, CBC recalls. A Michigan company mixed molasses, sugar and water at an Ontario facility. The process was legal and approved by Washington, then lawsuits and laws shut it down in the 2000s.

And yet, according to CBC, the August report of the U.S. Department of Agriculture describes molasses imports for sugar extraction as in rapid decline. It projects them at zero next year.

Sucro has already stopped

Don Hill chairs Sucro Can Sourcing, whose largest refinery is in Hamilton. The company shipped about 50,000 tonnes of refining molasses a year to the United States, he says, a fraction of 1% of the American market. U.S. customs had approved those imports in 2020, according to CBC.

Then Sucro stopped importing molasses into the United States, he says, after its new $135 million refinery in Hamilton was completed in April.

In April, the molasses stops leaving. In September, Washington bans it.

For Washington, 0.3% of imports. For this particular flow, almost nothing, even before the signature.

The Department of Agriculture told CBC that the study on the purity of that molasses had not been officially published. It had nothing else to share.

Nothing else.

An unpublished study. A published ban.

Banning a flow that was already drying up.

Who knows where to push

The Sugar Alliance applauds

The American Sugar Alliance, the main lobby of American sugar producers and refiners, welcomed the ban in a statement to CBC.

It thanks the president for ensuring that imported products are what they claim to be.

CBC asked the Office of the U.S. Trade Representative why molasses. No answer.

An alliance applauds. An office stays silent.

Rum and cows

Drew Fagan, a professor at the University of Toronto’s Munk School, reminds CBC that molasses is used to make rum and to feed dairy cows. Two possible links to alcohol and milk.

He adds that an interest group can carry a lot of weight if it knows which buttons to push. It is not unusual, he says, for a group to use a trade dispute to push through changes it has long wanted.

David Singerman, a historian at the University of Virginia, talks about sugar’s special status in the American trade system: quotas, a guaranteed minimum price, high import tariffs.

A warning to Canada can also be a gift to someone else. Sugar knows how to wait.

Behind the molasses, a patient lobby.

What is left on the shelf

The Cuban cigar

On the other side, NorthJersey.com asked the question on September 26: will Canadian whisky become a Cuban cigar?

For fans of Canadian whisky, the Cuban cigar could be a good historical example, answers Lawrence White, an economics professor at New York University’s Stern School.

Stock already in stores can be sold after the ban takes effect, says Patrick Penfield, of Syracuse University.

In the week of September 7, New Jersey liquor stores had not seen a rush on Canadian whisky.

The state imports $8.3 billion from Canada, according to figures from the Consulate General of Canada in New York cited by the paper. Whisky is just one line.

One way or another

Jason Miller, of Michigan State University, advises travellers not to bring back anything on the list.

Arthur Guarino, of Rutgers Business School, expects Canadian products to get in anyway, one way or another. At a steep price for the American consumer.

The last bottle on the last shelf will eventually go. Nobody will replace it at the same price. Then the empty shelf.

The American customer will pay for the warning sent to Ottawa.

Harder to lift

No waiver announced

That leaves the question of the exit. It is narrow.

The law firm Winston Taylor noted it on September 23. No general waiver or exception procedure has been announced, either for the bans or for the September 16 memorandum on public procurement.

That memorandum, at least, provides a way out: the trade representative can recommend reinstating Canadian products if Canada changes its policy.

Back to the tariff, by design

The ban proclamations write no such exit. They only provide for what happens if they are struck down: a return to the 50% tariff.

No date. No lifting clause.

According to The Associated Press, Barry Appleton sees nothing in these measures that serves economic efficiency or affordability. Less choice for the consumer. Disrupted supply chains.

Who in Washington will sign off on lifting it?

If nobody calls for it out loud…

With no exit in writing, the warning settles in.

A warning to everyone

Tuesday, the shelves

On Tuesday, at 12:01 a.m., the targeted products will no longer be admitted. Those already waiting in warehouses, not yet cleared, will still be taxed at 50%.

Bottled whisky, whey, molasses, non-alcoholic beer; on another list, big motorcycles, including those built in Valcourt, Quebec.

Less than half a percent of trade. A message to Canada and to everyone thinking of retaliating.

Small volume. Big address.

What we answer

A warning does not ask to be liked. A warning does not ask to be paid dearly. It asks you to hesitate.

Will we retaliate anyway against a move designed so that the next retaliation never happens?

The 0.3% does not answer that question. It asked it.

Too light to weigh, heavy enough to warn.
