Canada–US trade relations remain tense after talks between the two countries failed to reach a deal.

From August 22, 2026, the US has applied an additional 50% tariff to certain groups of Canadian goods worth a total of about US$20 billion.

Notably, on August 24, 2026, President Donald Trump also threatened to impose a 50% tariff on Canadian cars, trucks and auto parts from January 1, 2027.

Meanwhile, Canada plans to apply retaliatory measures to certain US goods from September 8, 2026.

For businesses shipping goods between Canada and the US, the question now isn’t just:

“What is the new tariff?”

More importantly:

“Is our shipment affected, and what do we need to prepare next?”

How is the new 50% US tariff being applied?

On August 22, 2026, the US began applying an additional 50% tariff to certain Canadian goods covered by the measures issued under Section 338 of the Tariff Act of 1930.

Affected groups include many consumer and industrial products, such as:

• Dairy and some food products
• Alcohol and beverages
• Electronics
• Furniture
• Cement and some building materials
• Paper and paper products
• Clothing, footwear and luggage
• Toys
• Cosmetics
• Some machinery and industrial products

The total value of goods covered by the new measures is estimated at about US$20 billion, roughly 5% of Canadian goods exported to the US.

Not all Canadian goods face the 50% tariff

The new tariff does not apply across the board to all Canadian goods.

The White House has specified which products fall under Section 338 and has excluded some groups, including energy, potash, some products subject to Section 232 and certain other goods.

So businesses shouldn’t rely on the product name alone to work out the tariff.

Check:

Product → HTSUS classification → country of origin → applicable tariff treatment

Does CUSMA exempt businesses from the 50% tariff?

Not necessarily.

A particularly notable feature of the new measures is that Section 338 tariffs apply to covered goods even if those goods qualify as originating under USMCA/CUSMA.

This means:

“CUSMA eligible” does not mean “automatically tariff-free”.

Businesses need to determine the exact tariff classification and the rules that apply to each shipment before calculating landed cost.

Check goods in transit now

For Canada → US shipments in transit, businesses should check:

• Where is the shipment?
• What is the ETA?
• Has the customs entry been filed?
• What is the HTSUS classification?
• Is the shipment on the affected list?
• What is the expected duty exposure?

In particular, the date the goods left Canada is not the only factor to consider.

Section 338 ties the additional duties to goods entered for consumption, or withdrawn from warehouse for consumption, from the effective time of each measure.

So businesses with goods in transit should work with their customs broker or importer of record to determine the specific tariff treatment.

Update August 25, 2026: the US threatens a 50% tariff on Canadian vehicles

After the 50% tariff on certain Canadian goods took effect, tensions continued to escalate.

On August 24, 2026, President Donald Trump said the US could impose a 50% tariff on Canadian cars, trucks and auto parts from January 1, 2027.

This is a tariff announced or threatened by Trump for 2027, not a 50% rate already applied to the entire Canadian automotive industry today.

Why should businesses care?

The Canada–US automotive industry has a highly integrated cross-border supply chain.

If the new tariff is implemented, the impact could spread to:

• Auto parts suppliers
• Manufacturers
• Warehouses
• Cross-border transportation
• Distribution networks

Businesses in the supply chain should start assessing their:

Tariff exposure → landed cost → inventory → transportation → supply chain

Reuters also reported concerns that the new tariffs could disrupt the integrated Canada–US automotive supply chain.

Note: January 1, 2027 is the date Trump announced for the new automotive policy. Businesses should not read it as a tariff already in force on all Canadian vehicles today.

Canada prepares counter-tariffs from September 8, 2026

Canada plans to apply “dollar-for-dollar” retaliatory measures to certain US goods from September 8, 2026.

The groups mentioned include:

• Steel
• Dairy products
• Household appliances
• Agricultural equipment
• Machinery
• Pulp and paper
• Electronics

Canada is also considering further responses to the latest US automotive announcement. On August 25, Canadian Minister Dominic LeBlanc said new retaliatory measures could be announced that day.

This matters especially for businesses that trade in both directions:

Canada → US and US → Canada

Businesses should assess tariffs and landed cost separately for each direction.

Three dates businesses need to watch

The situation may still change as Canada and the US continue negotiating.

So businesses should track tariff treatment and shipment status rather than relying on a rate announced at a single point in time.

What should businesses do right now?

1. Check your tariff classification

Don’t rely on the product name alone.

Check:

Product → HTSUS → country of origin → applicable tariff

In particular, confirm whether your product falls under the affected tariff lines.

2. Recalculate landed cost

Businesses should assess:

Product cost + shipping + duty + customs fees + other applicable charges

Then consider the impact on:

Landed cost → margin → selling price

An additional tariff can significantly change the profit on each shipment.

3. Review shipments in transit

If you have Canada → US goods on the move, check:

Location → ETA → entry → tariff → expected duty

Reviewing early gives you more time to work with your customs broker and prepare if extra costs or delays arise.

4. Watch both directions of Canada–US trade

If your business ships:

Canada → US and US → Canada, assess each direction separately.

Each direction may have:

• Different tariffs
• Different classifications
• Different customs requirements
• Different countermeasures
• Different cost exposure

5. Prepare for further changes

Current developments show that trade policy can change quickly.

Businesses should set up a simple monitoring process:

Monitor → check → calculate → coordinate → act

instead of waiting until a shipment runs into trouble before checking.
