Two major North American trade deadlines are converging within days of each other, and together they reshape the duty exposure of any company importing across the US, Canada, and Mexico corridor. The USMCA review 2026 is scheduled for July, the first joint review of its kind in any US free trade agreement, and it puts the future of Section 232 steel and aluminium tariffs on Canada and Mexico directly on the table. At the same time, on 30 June 2026, Canada ends a series of temporary tariff remissions that have shielded key imports for over a year. For importers of IT hardware, aerospace components, automotive parts, and manufactured goods moving across North American borders, the planning window is now measured in days, not months.
Together, the July review and Canada’s remission expiry create a near-term duty-repricing event for the North American corridor. The outcomes shape landed cost, duty exposure, and supply chain planning for the second half of 2026. This blog sets out exactly what is happening, the specific dates and measures involved, who is most exposed, and the concrete steps importers should take now to protect their position before the cliff arrives.
Executive briefing:
- The USMCA review (July 2026): the first scheduled joint review of the agreement, where members may assess the future of Section 232 steel and aluminium tariffs on Canada and Mexico
- The Canada cliff (30 June 2026): temporary tariff remissions end, raising costs on affected aerospace, manufacturing, and healthcare imports
- The Section 122 expiry (24 July 2026): surcharges on non-USMCA-compliant Canadian goods are set to expire unless Congress extends, with a possible increase to 15%
What the USMCA Review 2026 Actually Decides
The United States, Canada, and Mexico are scheduled to conduct a joint review of the United States-Mexico-Canada Agreement in July 2026. This is the first review of its kind in any US free trade agreement, which makes it both significant and unpredictable. The mechanics matter: if the parties do not reach agreement to extend the agreement before the review milestone, the USMCA does not end overnight, but it enters a path toward termination in 2036 after a decade of annual joint reviews. The agreement also allows for unilateral withdrawal on six months’ notice. Many trade analysts anticipate the USMCA will be amended rather than abandoned, but the shape of any amendments remains uncertain.
For importers, the most consequential question on the table is the treatment of Section 232 tariffs. As part of the review oversight, members may assess whether the United States should maintain or eliminate Section 232 steel and aluminium tariffs on Canada and Mexico, or exempt USMCA-compliant products. The US Trade Representative, Jamieson Greer, has floated the idea of separate protocols with Canada and Mexico tacked on to the USMCA to resolve bilateral issues, a similar approach to the side letters used to resolve the first round of Section 232 steel and aluminium tariffs in 2018 and 2019. Depending on the outcome, duty exposure for compliant goods could fall, or current tariffs could remain in place. The practical response is to plan for both relief and no-relief scenarios. Our detailed analysis of the review is in our guide to the 2026 USMCA review and what it means for importers.
The 30 June Canada Remission Cliff
While the USMCA review shapes the medium-term picture, a more immediate change lands on 30 June 2026. Canada is ending a set of temporary remissions that have provided relief on selected imports, and the expiry raises costs on affected goods straight away.
As of 30 June 2026, Canada ends the temporary remissions on aluminium goods used for manufacturing, processing, food and beverage packaging, and agricultural production, on goods used for public health, healthcare, public safety, and national security purposes, and on steel goods used for manufacturing motor vehicles, aerospace goods, and their parts. Some steel remissions, covering steel used for general manufacturing, processing, packaging, and agriculture, already expired earlier in 2026, so the 30 June date closes out much of the remaining relief. For companies whose supply chains depend on these categories, the cost increase is not a future risk. It is a scheduled event with a fixed date.
The Other Deadline: Section 122 Tariffs Expire 24 July
A third date completes the picture. Canadian-origin goods that do not qualify as USMCA-compliant are currently subject to a 10% tariff under Section 122 of the Trade Act of 1974, which authorises temporary import surcharges of up to 15% for 150 days to address balance-of-payments concerns. These Section 122 tariffs are set to expire on 24 July 2026 unless Congress votes to extend them, and the administration has signalled it could raise the rate to 15% without yet taking formal action. Critically, the Section 122 tariffs apply in addition to other customs duties, except the Section 232 measures that continue to apply to Canadian auto, steel, aluminium, copper, lumber, furniture, and cabinet exports. The detail of how this surcharge works is in our analysis of the Section 122 tariff and what importers need to know.
The Converging Deadlines at a Glance
| Date | Event | What Changes | Who It Affects |
|---|---|---|---|
| 30 June 2026 | Canada ends temporary import remissions | Costs rise on affected aluminium, steel, healthcare, and security goods | Manufacturers, aerospace, healthcare, and packaging importers into Canada |
| July 2026 | USMCA joint review | Section 232 treatment of Canada and Mexico is assessed; outcome uncertain | All importers on the North American corridor, especially steel and aluminium users |
| 24 July 2026 | Section 122 tariffs expire unless extended | Surcharge on non-USMCA Canadian goods ends, or could rise to 15% | Importers of non-USMCA-compliant Canadian-origin goods |
The pattern across all three is the same: duty exposure on the North American corridor is in flux, and the direction it moves depends on decisions being made in a matter of weeks. The importers who plan for the range of outcomes now will absorb whichever way it lands. Those who wait will be reacting after their costs have already changed.
Why the Section 232 Changes Make This More Complex
The Section 232 regime itself changed substantially earlier in 2026, which raises the stakes of the USMCA review. Under Proclamation 11021 of April 2026, the tariffs now apply to the full value of steel, aluminium, and copper products rather than just the metal content, derivative tariffs were simplified to a flat rate, a 10% tariff was introduced on derivatives containing primarily US-sourced metal, and the inclusions process was eliminated. A reduced rate of 15% on certain industrial and electrical grid equipment was set to run through 2027 to support US production investment.
The shift to full-value assessment is the change that matters most for landed cost, because it widened the base on which the tariff is calculated. For importers of derivative products containing steel or aluminium, including a great deal of IT hardware, machinery, and manufactured equipment, this means the duty exposure is larger than it was under the old metal-content method. Our breakdown of this change is in our analysis of Section 232 tariffs on full customs value. The USMCA review now sits on top of this, which is why the outcome for USMCA-compliant goods is so consequential.
Who Is Most Exposed
The convergence hits some sectors harder than others. The most exposed include the following.
- Aerospace and automotive: The Canada remission expiry directly affects steel used for motor vehicles, aerospace goods, and their parts, and Section 232 applies to Canadian automotive exports. Companies in these sectors face change from multiple directions at once
- IT hardware and machinery importers: The full-value Section 232 assessment on derivative products containing steel and aluminium raises landed cost on a wide range of equipment, and the USMCA review will determine whether compliant goods get relief
- Healthcare and medical equipment: The Canada remission on goods used for public health and healthcare purposes ends on 30 June, directly affecting importers in this category
- Manufacturers using aluminium and steel inputs: The remission expiry on aluminium and steel for manufacturing, processing, and packaging raises input costs for a broad base of producers
- Importers of non-USMCA-compliant Canadian goods: These face the Section 122 surcharge question on top of everything else, and the possibility of an increase to 15%
The common thread is that USMCA compliance status is now the single most valuable lever an importer has. Goods that qualify as USMCA-compliant stand to benefit most from any relief the review produces, and are already shielded from the Section 122 surcharge. Confirming and documenting USMCA origin is the highest-value action most importers can take right now.

USMCA Review 2026: What North American Importers Should Do Now
- Confirm your USMCA compliance status for every product. This is the most important step. USMCA-compliant goods are best positioned for any relief from the review and are already exempt from the Section 122 surcharge. Verify and document origin for your full product range now, not after a decision lands
- Model your landed cost under multiple outcomes. Build the duty picture for each scenario: remissions expired, Section 232 maintained, and Section 232 relief for compliant goods. Knowing your exposure under each lets you act immediately when the outcome is clear. Use our landed cost guide to structure this
- Identify your exposure to the 30 June remission expiry. Map which of your imports fall into the affected aluminium, steel, healthcare, and security categories, so you know exactly what changes on that date
- Review your Section 232 derivative exposure. With the tariff now assessed on full value, confirm how your steel and aluminium derivative products are classified and valued, because the base has widened
- Audit your bill of materials, HTS classification, and origin documentation. Trace the steel, aluminium, and component origins in your bill of materials, confirm the HTS classification of each affected product, and make sure your supplier origin certificates support a USMCA claim. This is the documentation that determines whether a product qualifies for compliant treatment, and it is the first thing scrutinised if challenged
- Get your import of record and compliance structure right. A period of duty change is exactly when accurate classification, valuation, and a compliant import structure protect you.

Frequently Asked Questions
What is the USMCA review 2026 and when does it happen?
The USMCA review 2026 is a joint review of the United States-Mexico-Canada Agreement scheduled for July 2026, the first review of its kind in any US free trade agreement. It will assess the future of the agreement, including whether Section 232 steel and aluminium tariffs on Canada and Mexico are maintained, eliminated, or modified for USMCA-compliant goods.
If the parties do not agree to extend the agreement at the review, the USMCA enters a path toward termination in 2036 after a decade of annual joint reviews. The widely expected outcome is amendment rather than termination, but the specific changes are uncertain, which is why importers should plan for a range of outcomes now.
What changes for Canadian imports on 30 June 2026?
On 30 June 2026, Canada ends temporary remissions on aluminium goods used for manufacturing, processing, food and beverage packaging, and agriculture, on goods used for public health, healthcare, public safety, and national security, and on steel goods used for manufacturing motor vehicles, aerospace goods, and their parts. Costs on these affected imports rise from that date.
Some steel remissions covering general manufacturing and processing use already expired earlier in 2026, so 30 June closes out much of the remaining relief. Importers in the affected categories should map their exposure before the date so the cost change does not catch them unprepared.
How does USMCA compliance affect my tariff exposure?
USMCA compliance status is the single most valuable lever for North American importers right now. USMCA-compliant goods are best positioned to benefit from any Section 232 relief the review produces, and they are already exempt from the Section 122 surcharge on non-compliant Canadian-origin goods. Confirming and documenting USMCA origin can materially lower duty exposure.
This is why verifying compliance across your full product range is the highest-priority action ahead of the deadlines. Goods that cannot demonstrate USMCA origin face the broadest exposure to the converging tariff changes, while compliant goods have the strongest position whatever the review decides.
What should importers do before these deadlines?
Confirm USMCA compliance for every product, model landed cost under multiple tariff outcomes, identify exposure to the 30 June remission expiry, review Section 232 derivative classification under the new full-value assessment, and ensure the import of record and compliance structure is accurate. These steps let an importer act immediately once the outcomes are known.
The common mistake is waiting for certainty before acting. Because the deadlines are days away and the outcomes are uncertain, the advantage goes to importers who have modelled their exposure in advance and can move the moment a decision lands, rather than starting the analysis afterwards.
For companies importing IT hardware, aerospace components, automotive parts, medical equipment, and manufactured goods across the North American corridor, Carra Globe’s Importer of Record services provide the classification discipline, landed-cost planning, and compliant import structure to navigate the converging deadlines. With tighter US enforcement also taking effect this year, covered in our analysis of the 2026 customs enforcement changes, getting the structure right has never mattered more.
