The U.S. import ban on Canadian goods took effect on September 29, 2026, covering specific products of Canada. The list includes alcoholic beverages, whey products, molasses, nonalcoholic beer, and motorcycles with engines over 800 cc.
For businesses buying these products, the change affects whether a shipment can enter the country. Covered goods imported on or after the cutoff are prohibited, while certain goods already imported remain subject to an additional 50% duty. Alcohol packaging also affects which treatment applies.
The restrictions took effect at 12:01 a.m. Eastern on September 29, following proclamations issued on September 8. This article brings together the complete product list, the tariff treatment, and the rules for goods already imported, based on the official annexes and U.S. Customs and Border Protection guidance.

What the ban covers
The three official annexes list 68 tariff and statistical lines: 53 for alcoholic beverages, 14 under the dairy proclamation, and one for motor vehicles. Several lines describe different forms of the same product, so this figure represents customs classifications.
| Product group | Lines listed | Main scope |
|---|---|---|
| Alcoholic beverages | 53 | Specified beer, wine, cider, spirits and other beverages, with packaging and classification limits |
| Whey products | 8 | Specified whey protein concentrates, modified whey, fluid whey and dried whey |
| Molasses | 5 | Invert, cane and other listed molasses |
| Nonalcoholic beer | 1 | HTSUS 2202.91.00 |
| Motorcycles | 1 | HTSUS 8711.50.00, covering reciprocating internal-combustion piston engines over 800 cc |

By the numbers
The scope is narrower than the broad labels suggest. The dairy proclamation includes molasses and nonalcoholic beer, but its exclusion list does not establish a general ban on Canadian milk, cheese or butter. The motor-vehicle exclusion is limited to the single motorcycle classification above.
The Canadian import restrictions apply to products of Canada. A product's customs origin, classification and any stated scope limitation determine coverage. Goods outside the exclusion lists can still face other tariffs and import requirements.

Why the restrictions were introduced
The administration invoked Section 338 of the Tariff Act of 1930. It says Canada continued discriminatory treatment of U.S. commerce after earlier tariff actions concerning alcohol, dairy and motor vehicles. USTR's September 8 statement sets out that position.
The additional 50% U.S. duties had taken effect on August 22, as covered in the earlier Canada tariff update. Canada introduced counter-tariffs on September 8, covering C$27.6 billion in U.S. imports. Canada's Finance Department describes those measures as a dollar-for-dollar response to the U.S. Section 338 tariffs. Canada's official counter-tariff list.
The United States issued the exclusion proclamations on September 8, alongside separate changes to its tariff lists. Those tariff changes became effective September 15; the import bans began September 29. CBP's tariff-modification notice.
What rates apply to affected imports?
The treatment depends on the goods and when they were imported. The rules create three distinct situations:
| Situation | Treatment under the September 29 restrictions |
|---|---|
| Listed Canadian products imported on or after the cutoff and meeting the relevant scope conditions | Importation prohibited; payment of the additional 50% duty does not authorize entry |
| Covered goods imported before the cutoff but still awaiting entry for consumption or withdrawal from a warehouse | The applicable additional 50% Section 338 duty remains in place under the transition provisions |
| Listed alcohol that falls outside an applicable scope limitation | CBP says the import exclusion does not apply and the applicable additional 50% duty remains |
Sources: CBP implementation guidance and the alcohol exclusion proclamation.

What a 50% additional duty means in dollars
The Section 338 duty is an ad valorem charge, calculated as a percentage of the customs value. In an illustrative case where the additional 50% duty applies to the full $10,000 customs value, that additional duty is $5,000. The goods' customs value plus this one duty would total $15,000, before other applicable duties, taxes, fees, freight or related costs.
That calculation applies only where importation remains permitted and the duty is applicable. It does not provide a price at which a prohibited shipment can enter.
The 50% figure also does not represent a universal total tariff on Canadian goods. CBP's tariff guidance preserves other applicable charges and sets out specific exceptions. The final amount depends on the product's classification and entry treatment. CBP tariff guidance.
What this means for customer prices
The proclamations establish import restrictions and customs treatment. They do not set wholesale or retail prices, and a 50% additional import duty does not establish a 50% increase in the price paid by a customer.
Where the duty still applies, it increases the import cost on the relevant customs value. How much of that cost reaches a customer depends on the seller's pricing and the other costs included in the selling price. Where importation is prohibited, the immediate effect is that covered new shipments cannot enter. The official notices do not provide a fixed percentage increase for replacement stock or consumer prices.
Does USMCA qualification change the position?
The White House states that the Section 338 duties apply to covered goods regardless of USMCA qualification. CBP's exclusion guidance provides no blanket USMCA exemption for the banned products. A preferential tariff claim therefore does not establish that a listed, covered shipment is admissible. White House fact sheet and CBP guidance.
What other sourcing options do businesses have?
Businesses can buy U.S.-produced goods, source products made in another country, or purchase inventory already lawfully available through U.S. distributors. These alternative sourcing options have different cost structures. Buying from a U.S. distributor can simplify the purchasing process, but imported stock may already include tariffs and freight in its price.

The examples below identify existing production sources and possible category substitutes. They do not establish available capacity, a vendor's willingness to take new orders, or an identical replacement for a Canadian product. The cost considerations explain how these purchases work. The separate food prior-notice requirements and import licensing requirements remain relevant to replacement purchases where applicable. Actual savings depend on the transaction.
Domestic and international alternatives by product group
| Affected products | Domestic options | International options | What changes the cost comparison |
|---|---|---|---|
| Beer, wine, cider and other fermented beverages | U.S. breweries and wineries offer locally produced alternatives. Matching a particular style, brand or recipe is a separate question. | Mexican-produced beer and French or Italian wine are established examples of non-Canadian supply. Specialty products, including sake, prune wine and vermouth, require a producer offering the particular category. | Delivered case price, bottle or keg size, alcohol content, excise tax, freight and distribution terms. A different brand or appellation can change the selling proposition as well as the purchase price. |
| Whiskies, brandies, rum, gin, vodka, liqueurs, bitters and beverage alcohol | U.S. distillers and licensed distributors offer alternatives within many of these categories. | Examples include whisky produced in Scotland or Ireland and tequila produced in Mexico. Other listed specialty spirits require their own product-specific source. | Age, proof, formulation, brand, package size and tax treatment affect comparability. An American whiskey cannot be sold as Canadian whisky merely because it fills the same place in a distributor's range. |
| Nonalcoholic beer | Athletic Brewing identifies production facilities in Connecticut and Southern California. | ERDINGER produces beer in Erding, Germany, and offers nonalcoholic products. | Case price, packaging, shipment size, freight and remaining shelf life. An imported alternative can have a lower factory price yet a higher delivered cost. |
| Whey protein concentrates, modified whey and dried whey | The U.S. Dairy Export Council's vendor directory includes U.S. producers of whey concentrates, sweet whey powder and demineralized whey. | Arla Foods Ingredients identifies whey processing at Danmark Protein in Denmark. Suitability depends on the exact ingredient specification. | Protein concentration, mineral content, functionality, testing, freight and contract volume. A price per pound for ordinary dry whey does not provide a comparable price for a higher-protein concentrate. |
| Fluid whey | Supply from a domestic cheese or whey processor is a potential route where the required liquid product is available. | Overseas dry ingredients may offer a reformulation route where technically suitable; the cited dry-whey sources do not establish a direct overseas replacement for fluid whey. | Liquid transport, handling and storage have a different cost basis from powder. Reformulation can add processing and validation costs, so the two forms cannot be treated as equivalent purchases. |
| Invert, cane and other molasses | Florida Crystals documents molasses production at its Florida mills. This establishes a domestic cane-molasses source, with suitability depending on grade and use. | Belize Sugar Industries documents molasses export infrastructure in Belize. This does not establish availability of every listed molasses type. | Sugar concentration, food or feed specification, tank or container handling and inland freight. Cane molasses, beet molasses and invert molasses are separate specifications; one source does not automatically replace all five tariff lines. |
| Motorcycles over 800 cc | Harley-Davidson's York, Pennsylvania, plant produces Touring and Trike models. | BMW's Berlin plant produces motorcycles including the R 1300 GS and S 1000 RR. | Model and equipment, dealer terms, freight, applicable duties, warranty and servicing arrangements. A replacement brand may require a different dealership relationship and parts inventory. |

How domestic and overseas costs differ
For a U.S.-produced finished product purchased domestically, the buyer has no import entry or customs duty on that purchase. The price can still reflect the producer's imported inputs, manufacturing costs and domestic transportation. Domestic availability alone does not establish a lower delivered price.
For a non-Canadian import, the cost can include the vendor's price, international freight and insurance, customs duties, clearance charges and delivery within the United States. The applicable tariff depends on the actual origin, classification and entry date. The Canadian exclusion does not establish a zero-duty rate for replacement goods from Mexico, Europe or elsewhere. Routing Canadian goods through another country does not by itself establish a different origin.
Alcohol also has a separate federal excise-tax layer. TTB lists general rates of $18 per barrel of beer, $1.07 per wine gallon for still wine at 16% alcohol or below with no more than 0.392 grams of carbon dioxide per 100 milliliters, and $13.50 per proof gallon of distilled spirits. These rates apply to specified volume or proof-volume units. Reduced rates or credits may apply, including through qualifying assignments from foreign producers. Domestic alcohol can also bear federal excise tax, so replacing imported stock does not remove that cost automatically. TTB tax rates.
