There are two separate things happening in U.S.-Canada trade right now, and they are being confused with each other constantly.
The first is the USMCA joint review. On July 1, 2026, the USMCA Free Trade Commission held the agreement's first mandatory six-year review. The United States did not agree to renew the agreement. USTR's statement said plainly that "the USMCA is not renewed."
The second is a new tariff action that has nothing to do with the review outcome and does not care whether your goods qualify under USMCA at all.
Here is the part shippers need to understand.
USMCA did not expire. It remains in force. Preferential tariff treatment continues.
But on August 19, 2026, a separate 50% tariff takes effect on a specific list of Canadian goods, and USMCA origin does not exempt them.
If you move freight from Canada into the United States, the second item is your near-term problem. The first is your planning problem.
The immediate deadline: 50% Section 338 tariffs, effective August 19
On July 20, 2026, the administration signed three proclamations under Section 338 of the Tariff Act of 1930, imposing an additional 50% ad valorem tariff on specified Canadian products.
The details that matter operationally:
Effective date. 12:01 a.m. Eastern Time on August 19, 2026.
What triggers the duty. Goods entered for consumption, or withdrawn from warehouse for consumption, on or after that date. This is not based on when the truck crossed or when the goods arrived. Existing bonded inventory withdrawn for consumption on or after August 19 is subject to the duty.
USMCA does not provide relief. This is the critical point. Covered goods are subject to the 50% duty regardless of whether they qualify under USMCA rules of origin. A valid certification of origin does not exempt a product named in the proclamations. This is a meaningful departure from earlier Canada tariff actions, which generally spared USMCA-originating goods.
Scope. USTR has estimated the three proclamations cover roughly $20 billion in annual Canadian imports across hundreds of eight-digit HTSUS classifications, or about 5% of total U.S. imports from Canada.
Covered categories. The three proclamations address dairy, alcoholic beverages, and automotive discrimination, but the auto-related proclamation reaches well beyond autos. Reported coverage includes dairy and agricultural products, alcoholic beverages including wine, manufactured goods, chemicals, cosmetics, wood and paper products, cement, jewelry, meat, plants, and sporting goods including hockey equipment.
Excluded. Energy products, potash, critical minerals, fish, and goods already subject to Section 232 tariffs are excluded. That Section 232 carve-out covers steel, aluminum, copper, lumber, and autos and auto parts already under Section 232, including those that qualify for duty-free USMCA entry. Civil aircraft and aircraft parts are also excluded.
Foreign Trade Zones. Covered merchandise admitted to a U.S. FTZ on or after August 19 must generally be admitted under privileged foreign status unless eligible for domestic status.
No expiration date. Unlike some other tariff authorities, Section 338 carries no fixed sunset. These duties remain in place unless modified or terminated.
It could still change. The 30-day notice period was built to allow negotiation. Canada has put concessions on the table, including alcohol restrictions, dairy quota treatment, and auto tariffs, though some provincial cooperation remains unresolved. The action may also face legal challenge. Do not assume the tariffs will be withdrawn, and do not assume they will not be.
Section 338 has been on the books since 1930 and has not previously been used to impose tariffs at this scale. There is no established playbook for it. Check the annexes against your Canadian-origin import lines now rather than after the effective date.
What actually happened at the July 1 joint review
USMCA entered into force on July 1, 2020.
Article 34.7.2 requires the Free Trade Commission to conduct a joint review of the agreement on the sixth anniversary of entry into force. The Commission met virtually on July 1, 2026, for that purpose.
The United States did not confirm its intention to extend the agreement for an additional 16-year period. Canada and Mexico both confirmed their support for extending it.
USTR's statement said the United States "did not agree to renew the USMCA in its current form" and that "as a result, the USMCA is not renewed." The same statement confirmed that the agreement "remains in force."
That last sentence is the one that got lost in the headlines.
"Not renewed" does not mean expired
The agreement has neither lapsed nor terminated.
Under Article 34.7.1, USMCA runs a 16-year term from entry into force, through July 1, 2036. What did not happen on July 1, 2026, was the optional decision to extend that horizon by a further 16 years.
The review was a decision point, not an expiration date.
What Article 34.7.4 now triggers
Because the United States did not confirm an extension at the joint review, Article 34.7.4 is now active. Two things follow.
Annual joint reviews. The Free Trade Commission must now conduct a joint review every year for the remainder of the agreement's term, meaning annually through July 1, 2036.
An "at any time" extension pathway. The parties can still extend the agreement for an additional 16 years at any point before expiry by confirming that intention in writing through their respective heads of government. No formal renegotiation is required for that step.
The practical read is that the extension is deferred, not lost. It also means shippers now face a recurring annual decision point rather than a single settled outcome.
What did not change
This is the section your transportation and finance teams need.
Preferential tariff treatment continues. Goods that qualify under USMCA and CUSMA rules of origin can continue to receive applicable preferential treatment.
Rules of origin remain relevant. The qualification standards did not disappear.
Certification requirements continue. Businesses claiming preferential treatment still need proper origin documentation.
Investment protections and dispute settlement remain operative.
July 1, 2036 remains the end point of the current term unless the parties extend under Article 34.7.4.
What actually changed for shippers
1. The long-term planning horizon is less certain, and now resets annually
Companies making multi-year decisions on North American sourcing, manufacturing, warehousing, or distribution have more policy uncertainty to model, and a new review cycle to track every year through 2036.
That matters for decisions such as inventory positioning, dual-sourcing of components, long-term supplier commitments, manufacturing investment, distribution-center location, and cross-border network design.
Those are strategic decisions. Your truck still needs to cross the border this week.
2. USMCA preference is no longer a reliable shield against tariff exposure
This was always true in principle. The Section 338 action made it concrete.
Shippers need to run two separate analyses:
Does the product qualify for USMCA preference?
Are there other tariffs or trade measures that apply to the product anyway?
Answering the first question does not answer the second. In 2026, a product can be fully USMCA-originating and still carry a 50% additional duty.
3. The tariff authority landscape shifted in February
On February 20, 2026, the Supreme Court held 6-3 in Learning Resources, Inc. v. Trump that the International Emergency Economic Powers Act does not authorize the President to impose tariffs. All IEEPA-based tariffs terminated on February 24, 2026, including the Canada tariffs imposed from March 2025.
The Court did not resolve refunds. That question went back to the Court of International Trade, where refund litigation and claim processes are still working through. Importers who paid IEEPA duties should be talking to counsel or their broker about preserving refund rights if they have not already.
Section 232 tariffs on steel, aluminum, copper, lumber, and autos were not affected by that ruling and remain in force.
The net effect is that the tariff picture on Canadian freight has changed twice in six months, in opposite directions. Landed-cost models built at the start of the year are not reliable now.
4. Documentation discipline matters more, not less
Trade-policy uncertainty is not a reason to become less careful with origin documentation.
Preference claims still need to be supportable. A certification that cannot be substantiated can create duties, penalties, verification requests, delays, and retroactive adjustments.
Assume the documentation behind any claim should be strong enough to withstand review.
Rules of origin: the part shippers often misunderstand
A product does not qualify for USMCA preference simply because it was shipped from Canada to the United States, or from the United States to Canada.
Origin is not determined by where the truck picked up.
It depends on how and where the product was produced, and on the rules applicable to that tariff classification.
Depending on the product, qualification may involve wholly obtained goods, tariff-shift requirements, regional-value-content thresholds, product-specific rules, or additional sector-specific requirements.
The exact rule depends on the product.
Practical checks before claiming preference
Confirm the HS classification
Identify non-originating inputs
Determine the applicable product-specific rule
Keep supporting records
Reassess qualification when suppliers, materials, or manufacturing processes change
If the analysis is unclear, involve a qualified customs broker or trade adviser before making the claim.
Why classification matters more this month than last
Rules of origin begin with classification. The product-specific rule you apply depends on the HS classification.
A classification error creates two problems at once: the wrong duty treatment and the wrong origin analysis.
As of August 19, it can create a third. The Section 338 annexes are classification-based. Whether a Canadian-origin shipment carries an additional 50% duty depends on where it lands in the tariff schedule, not on whether it is USMCA-qualifying.
Classification is not administrative housekeeping. It is landed-cost accuracy.
Where the negotiations actually stand
The United States has pursued separate bilateral tracks rather than a single trilateral process.
The United States and Mexico have completed multiple negotiating rounds, beginning in Mexico City in late May, continuing in Washington in June, and returning to Mexico City in late July. Those discussions have covered automotive rules of origin, steel and aluminum, economic security, agriculture, labor, and environment.
Canada participated in the July 1 joint review meeting but had not begun substantive text-based negotiations with the United States as of late July. Canada's stated priority has been addressing U.S. sectoral tariffs on steel, aluminum, autos, and lumber. Following the Section 338 proclamations, both governments agreed to intensify discussions.
For shippers, the asymmetry between the two tracks is the thing to watch. The Canada relationship is the less settled of the two.
What this means for cross-border capacity
Trade policy is landing on top of a freight market that has already tightened.
Truckload capacity has contracted meaningfully through 2026, driven more by supply-side pressure than demand recovery. Carrier exits, driver availability, and enforcement activity have all reduced available capacity.
The numbers are not subtle. ACT Research reported aggregate spot rates excluding fuel up 43% year over year in June, with contract rates up 13%. Second-quarter shipper spending rose 28.1% year over year even as shipment volumes fell. Tender rejection rates have reached their highest levels since 2022.
When contract rates move like that, the pressure is structural rather than seasonal.
Cross-border freight carries an additional constraint. Not every carrier is genuinely equipped to run the border.
Successful U.S.-Canada freight may require appropriate carrier credentials, border experience, accurate documentation, eManifest processes, customs-broker coordination, driver eligibility, understanding of crossing procedures, and realistic timing around customs clearance.
The number of carriers willing to quote a cross-border load is larger than the number capable of executing it reliably. That difference matters more in a tight market than a loose one.
Carrier selection has also drawn more scrutiny in 2026 following litigation over broker responsibility in carrier vetting. Whatever the eventual outcome of that line of cases, the direction of travel favors documented, disciplined carrier qualification over the widest possible net.
Seven things shippers should do now
1. Check your Canadian-origin lines against the Section 338 annexes this week
This is the time-sensitive item. Pull your Canadian import lines by HTS code and cross-check them against the annexes of all three proclamations. Do not assume USMCA qualification protects you. Do not assume your product is out of scope because it is not dairy, alcohol, or an automobile.
2. Decide what moves before August 19 and what does not
The duty attaches on entry for consumption or withdrawal from warehouse. If you have covered goods, the timing of entry matters. So does bonded inventory you were planning to withdraw later this month.
3. Audit preference claims
Start with your highest-volume cross-border SKUs. Confirm HS classification, applicable origin rule, supporting documentation, supplier information, and certification process.
4. Re-model landed cost by classification
Separate USMCA preferential treatment from Section 232 exposure from Section 338 exposure. Do not collapse every trade-policy variable into one assumption. In 2026 they behave differently and change on different schedules.
5. Talk to your customs broker before the shipment
Border preparation starts before the truck reaches the crossing. Engage the broker early enough to identify missing or incorrect documentation before pickup, or while corrective action is still possible.
6. Map your cross-border carrier bench
Know which providers on your lanes are genuinely equipped for cross-border freight. Border experience matters, and it matters more when capacity is tight.
7. Build scenarios instead of forecasting policy
You do not need to predict every outcome. You do need to know what your network does under several plausible ones.
Model what happens if the August 19 tariffs take effect as written, if they are withdrawn or narrowed, if a further sectoral measure lands, if a supplier no longer qualifies, or if a sourcing lane stops making sense.
Scenario planning is more useful than pretending the answer is certain.
How Varstar Alliance supports cross-border shippers
U.S.-Canada freight is a core service area for Varstar Alliance.
PARS/PAPS coordination built into the workflow. Shipment information can be prepared and coordinated before the truck reaches the border.
Documentation readiness before pickup. The goal is to catch operational documentation issues early rather than discovering them at the crossing.
Access to dedicated and vetted cross-border capacity. Border-capable carrier relationships can be planned around recurring freight instead of relying solely on last-minute spot coverage.
Lane planning based on real market conditions. Cross-border capacity and pricing shift. Planning needs to consider execution risk alongside rate.
Varstar Alliance is not a customs broker and does not provide legal or trade advice.
We support the freight side of the shipment, including carrier coordination, timing, communication, and documentation readiness. Customs classification, tariff exposure analysis, and trade advice should come from qualified customs and legal professionals. That is especially true for the Section 338 action, where scope is determined line by line in the tariff schedule.
The bottom line
USMCA was not renewed at the July 1, 2026 joint review. It also did not expire. The agreement remains in force through July 1, 2036, with annual reviews now required and a written extension still available at any time.
Separately, a 50% tariff on a specific list of Canadian goods takes effect on August 19, 2026, and USMCA origin does not exempt covered products.
Those are two different problems on two different clocks.
The strategic one is about how you plan the next several years. The operational one is about what enters the United States next week.
Tighten what you control: classification, origin analysis, documentation, customs coordination, landed-cost modelling, and cross-border carrier planning.
Trade policy will keep moving. Your freight still needs to cross the border this week.
Frequently Asked Questions
Did USMCA expire in 2026?
No. The 2026 joint review did not terminate the agreement. USMCA remains in force under its existing 16-year term, which runs through July 1, 2036.
USTR said the USMCA "is not renewed." What does that actually mean?
It means the United States declined the optional decision to extend the agreement for a further 16 years beyond its current term. The same USTR statement confirmed the agreement remains in force. Not renewed is not the same as expired or terminated.
Do qualifying goods still receive USMCA preferential treatment?
Yes. Goods that satisfy the applicable rules of origin can continue to receive applicable preferential tariff treatment while the agreement remains in force.
What are the Section 338 tariffs and when do they start?
They are an additional 50% ad valorem duty on a specified list of Canadian products, imposed by three proclamations signed July 20, 2026 under Section 338 of the Tariff Act of 1930. They take effect at 12:01 a.m. Eastern on August 19, 2026, for goods entered for consumption or withdrawn from warehouse for consumption on or after that date.
Does USMCA qualification exempt my goods from the Section 338 tariffs?
No. This is the detail most importers miss. Covered goods are subject to the duty regardless of USMCA origin. A valid certification of origin does not exempt a product named in the proclamations.
What is excluded from the Section 338 tariffs?
Energy products, potash, critical minerals, fish, and goods already subject to Section 232 tariffs, which includes steel, aluminum, copper, lumber, and autos and auto parts under Section 232. Civil aircraft and parts are also excluded. Scope is determined by tariff classification, so confirm your specific lines against the annexes.
Could the August 19 tariffs be delayed or withdrawn?
Possibly. The 30-day notice period was intended to allow negotiation, and discussions between the two governments are active. The action may also face legal challenge. Plan for the tariffs taking effect as written while monitoring for change.
What happened to the IEEPA tariffs on Canada?
The Supreme Court ruled on February 20, 2026 that IEEPA does not authorize the President to impose tariffs. Those tariffs terminated on February 24, 2026. Refund questions were sent back to the Court of International Trade and remain in process. Section 232 tariffs were not affected and remain in force.
How often will USMCA be reviewed now?
Annually. Because the parties did not confirm an extension at the first joint review, Article 34.7.4 requires the Free Trade Commission to conduct a joint review every year for the remainder of the term, through July 1, 2036.
Can USMCA still be extended?
Yes. Under Article 34.7.4 the parties can extend the agreement for an additional 16 years at any point before expiry by confirming that intention in writing through their heads of government. No formal renegotiation is required for that step.
Should I change my cross-border freight strategy?
Not because the July review happened. Possibly because of the August 19 tariffs, depending on what you move. Use both as a reason to audit classifications, origin claims, landed-cost assumptions, customs processes, and cross-border capacity.
Why can cross-border capacity be harder to find?
Because not every carrier is equipped or experienced enough to execute U.S.-Canada freight reliably. Cross-border moves add documentation, customs coordination, credentials, and operational procedures that reduce the effective carrier pool. Overall truckload capacity has also tightened through 2026.
Does Varstar Alliance provide customs brokerage?
No. Varstar Alliance is a freight brokerage and logistics partner. We support transportation execution and cross-border coordination. Customs entries, classification advice, tariff exposure analysis, and legal or trade advice should come from your qualified customs broker or adviser.
