An import ban on certain Canadian dairy products has been in force since September 29, replacing a 50 percent additional duty on the same goods. President Trump signed the measure, Proclamation 11062, on September 8, and the Federal Register published it September 14. It bans the goods outright rather than taxing them.
What the proclamation does
The operative language says certain products of Canada, as listed in an annex, “are excluded from importation into the United States.” The ban applies to covered goods imported on or after 12:01 a.m. eastern time on September 29, 2026. The proclamation’s full title says it responds to “continued discrimination against the commerce of the United States with respect to dairy.”
The annex that lists the covered products is attached to the White House text as a file named for dairy, and a KPMG tax summary describes the proclamation as one that “excludes certain Canadian dairy products from importation into the United States.” The proclamation names no individual product and puts no dollar figure or quantity on the ban.
For a household, the pocketbook question is whether the dairy case will cost more. Nothing in the proclamation answers that. It sets no price, estimates no effect on grocery bills, and does not say which products on a store shelf, if any, come from the covered Canadian goods. The practical change is on the import side: covered goods that arrive on or after September 29 are barred, and goods that were imported but not yet entered for consumption or withdrawn from a warehouse before that date remain subject to the 50 percent duty instead.
A grocery bill can move for reasons a household cannot control, and an import ban on Canadian dairy is one more of them.

How it got here
The ban follows a duty fight that started in July. Proclamation 11047, dated July 20, 2026, found that Canada discriminates against U.S. commerce through “tariff-rate quota allocation measures imposed on U.S. cheeses of all types.” It set additional duties of 50 percent ad valorem, meaning 50 percent of the goods’ value, under section 338 of the Tariff Act of 1930.
A later proclamation suspended those duties for three days in August after Canada expressed a commitment to remove the discrimination. The proclamation says Canada then “reneged on its commitment” on August 21 and “ceased negotiating in good faith.” The suspension lapsed at 12:01 a.m. on August 22, and the duties took effect. Officials later reported that Canada had not revoked its dairy quota allocation measures, the finding on which the new ban rests.
Who enforces the ban
The proclamation hands the details to Customs and Border Protection. Its commissioner, consulting the Treasury Department, the Commerce Department and the U.S. Trade Representative, may issue rules and guidance to carry out the ban. CBP will also work out any needed changes to the Harmonized Tariff Schedule, publish them in the Federal Register and can make technical corrections to the annex. Where rules need presidential approval, the proclamation gives that approval authority to the U.S. Trade Representative.
The proclamation also anticipates a legal challenge. It says that if the ban is invalidated for any import, the 50 percent duty from Proclamation 11047 applies to that import instead. Section 338 is the legal basis; the proclamation cites it as allowing duties of up to 50 percent ad valorem and the exclusion of a country’s goods if its discrimination continues. The KPMG summary adds that section 338 duties apply in addition to section 232 duties and apply whether or not goods qualify under the USMCA, the trade agreement among the United States, Canada and Mexico.
Two companion bans on the same day
Dairy was one of three Canadian import exclusions published September 14. The Federal Register listing for that stretch of presidential documents shows proclamations excluding Canadian motor vehicles and alcoholic beverages as well, along with two proclamations modifying which products face the additional duties. The motor vehicle and alcohol bans also take effect September 29, according to KPMG.
The proclamation sets no end date and no review date.
Keeping up with a grocery bill that moves
The proclamation text and any later changes are posted at the Federal Register, where CBP’s follow-up notices on the tariff schedule will also appear. A reader who wants the covered products can look for the annex to Proclamation 11062, whose product list is an image on the Federal Register page and a separate file on the White House site.
A household that watches its grocery spending can start with its own receipts. Comparing a month of dairy purchases against the following month is the plain way to see whether any price change shows up in the cart, since the proclamation puts no price on the ban. Benefit programs that help with food costs are separate from trade policy and have to be applied for.
Proclamation 11062 itself says what changes and when: covered Canadian dairy goods entering on or after September 29, 2026 are excluded, and earlier entries stay under the 50 percent duty of Proclamation 11047.
A dairy ban the grocery bill can’t dodge
Trade fights between Washington and Ottawa can move prices at the dairy case, and household budgets absorb the change. The Benefits Checklist covers 11 benefit programs, including SNAP and heating help, with the 2026 income limits and a printable tracker that comes with the download, so a household can see which programs to apply for.
