New 50% Tariffs Announced on Certain Canadian Imports
Published: July 21, 2026
On July 20, 2026, President Donald Trump signed three proclamations imposing additional tariffs on Canadian imports. The measures were issued under Section 338 of the Tariff Act of 1930 and address U.S. trade concerns involving motor vehicles, alcoholic beverages, and dairy products.
The additional duties are scheduled to take effect at 12:01 a.m. Eastern Time on August 19, 2026. Covered merchandise entered for consumption—or withdrawn from a warehouse for consumption—on or after that time will generally be subject to an additional 50% ad valorem duty.
Importers should use the period before the effective date to determine whether their products are covered, confirm tariff classifications, review country-of-origin determinations, and recalculate anticipated landed costs.
What Has Changed?
The three proclamations apply an additional 50% tariff to separate groups of Canadian products. According to the White House fact sheet, the covered merchandise includes products ranging from wine and hockey sticks to cement.
The specific products subject to the tariffs are identified through the Harmonized Tariff Schedule of the United States classifications contained in the annexes accompanying the proclamations. Importers should not rely solely on general product descriptions when evaluating exposure.
A product’s tariff treatment will depend on its classification and whether it falls within one of the listed provisions.
The White House also stated that the additional duties apply to covered products regardless of whether they qualify as originating goods under the United States-Mexico-Canada Agreement. In other words, USMCA eligibility does not, by itself, exempt a covered product from these Section 338 duties.
Which Products Are Excluded?
The White House fact sheet identifies several broad exclusions. The additional Section 338 tariffs will not apply to:
- Energy products.
- Potash.
- Products subject to Section 232 tariffs.
- Certain fish products.
- Certain critical minerals.
- Other merchandise excluded under the proclamations and accompanying annexes.
The proclamations also provide exclusions for certain civil aircraft articles. Because the exclusions may depend on a product’s HTSUS classification and treatment under other tariff programs, importers should review each item individually rather than assuming an entire product category is exempt.
Why Classification Matters
When a tariff action is tied to specific HTSUS provisions, classification becomes central to compliance and cost planning.
An incorrect classification could cause an importer to:
- Pay duties that do not apply.
- Fail to deposit duties that are legally owed.
- Miscalculate landed costs.
- Provide inaccurate information to customers or purchasing teams.
- Face corrections, penalties, or additional scrutiny after entry.
Importers should compare their existing classifications with the tariff provisions listed in the applicable annexes. Product descriptions, technical specifications, material composition, principal use, and manufacturing information may all be relevant to the review.
This is also an appropriate time to confirm that Canadian origin is properly supported. Country of export and country of origin are not always the same, and tariff applicability generally cannot be determined from the shipping location alone.
Questions Importers Should Ask Now
The August 19 effective date gives businesses a limited period to assess the effect of the new duties.
Importers should begin by asking:
- Do any of our products fall within the covered HTSUS provisions?
- Have our classifications been reviewed recently?
- Are any affected goods currently in transit?
- When are those goods expected to be entered for consumption?
- Are any products stored in a bonded warehouse or foreign-trade zone?
- Do the goods qualify for an identified exclusion?
- Are they already subject to Section 232 duties?
- How will the additional duty affect landed cost and pricing?
- Do purchasing teams, suppliers, customers, and finance departments need updated information?
- Are future purchase orders based on cost assumptions that are no longer accurate?
The proclamations state that covered goods admitted into a U.S. foreign-trade zone on or after the effective date generally must be admitted in privileged foreign status, unless they qualify for domestic status. Importers using foreign-trade zones should review this requirement carefully with their customs and FTZ professionals.
Avoid Making Decisions Based on Headlines Alone
A 50% additional tariff is significant, but the announcement does not mean that every product imported from Canada will receive the new duty.
The first step should not be an immediate change in sourcing or purchasing strategy. It should be a careful analysis of the merchandise.
Importers need to determine:
- The correct classification.
- The correct country of origin.
- Whether the classification is listed in an applicable annex.
- Whether an exclusion applies.
- The date and entry status of affected shipments.
- The combined effect of existing and additional duties.
Only after those questions have been answered can a company accurately evaluate its financial exposure and available options.
Every tariff announcement creates questions, but the first step is not changing your supply chain. It is understanding exactly how the new rules apply to your products. Careful review today helps prevent costly surprises at entry tomorrow.
What Importers Should Do Next
Importers potentially affected by the new tariffs should take several practical steps before August 19:
- Review the annexes and covered HTSUS provisions.
- Confirm classifications and origin determinations.
- Identify open purchase orders and in-transit shipments.
- Review entry dates rather than relying only on departure or arrival dates.
- Recalculate duty exposure and landed costs.
- Notify internal stakeholders of potential pricing changes.
- Preserve supporting classification and origin documentation.
- Monitor CBP instructions and Federal Register notices for implementation details or technical corrections.
The proclamations authorize U.S. Customs and Border Protection to issue guidance, instructions, determinations, and necessary HTSUS modifications. Importers should therefore continue monitoring official developments as the implementation date approaches.
Preparation Provides the Clearest Path Forward
Trade policy can change quickly. Sound import compliance practices provide consistency when it does.
The latest tariffs on Canadian products reinforce the importance of accurate classifications, documented origin determinations, shipment visibility, and early communication among purchasing, finance, logistics, and customs teams.
Importers should avoid making assumptions based on broad product categories or USMCA eligibility. A product-specific review is necessary to determine whether the new duty applies and how it may affect upcoming entries.
Coppersmith’s customs professionals are reviewing the proclamations and related tariff provisions. Importers with potentially affected Canadian merchandise should examine their classifications and entry schedules before the August 19, 2026, effective date.
