USMCA Exemption From Section 122 Tariff Extended Indefinitely: What Importers Need to Know
USMCA Exemption From Section 122 Tariff Extended Indefinitely
On April 2, 2026, the administration extended the USMCA exemption from the Section 122 universal tariff indefinitely, removing the previous expiration date that had been set for that same day. Simultaneously, the exemption covering automobile imports was also extended indefinitely. For importers sourcing from Canada or Mexico, this is significant: USMCA-qualifying goods remain fully exempt from the 15% Section 122 surcharge for the foreseeable future.
### Background: The Section 122 Tariff Landscape
Section 122 of the Trade Act of 1974 (19 U.S.C. § 2132) grants the President authority to impose a temporary surcharge of up to 15% on imports to address balance-of-payments deficits. Following the Supreme Court's February 2026 ruling striking down IEEPA-based tariff authority, the administration invoked Section 122 as a replacement framework, imposing a 10% universal tariff effective February 24, 2026. That rate was subsequently raised to its statutory maximum of 15% on February 22, 2026.
Section 122 tariffs carry a hard statutory limit: they expire after 150 days unless Congress acts to extend them. That places the current expiration date at July 24, 2026. Whether Congress will vote to extend the authority — or allow it to lapse while new permanent tariff mechanisms take shape — remains the central trade policy question for the second half of 2026.
### What the USMCA Exemption Means in Practice
From day one of the Section 122 regime, goods that qualify for preferential treatment under the United States-Mexico-Canada Agreement have been exempt from the surcharge. That exemption was structured as temporary, with an initial expiration of April 2, 2026. Today's proclamation removes that expiration date, making the USMCA exemption effective for the full remaining duration of the Section 122 period.
In practical terms, this means:
Canada-origin goods qualifying under USMCA: No Section 122 tariff applies. The landed cost calculation for Canadian imports is unchanged from pre-February 2026 levels, subject only to base MFN rates and any applicable Section 232 duties (which continue to apply to steel and aluminum from all countries, including Canada and Mexico, at 50%).
Mexico-origin goods qualifying under USMCA: Same treatment. Zero Section 122 exposure on USMCA-qualifying goods. Note that Section 232 on steel and aluminum still applies; those are separate tariff actions that predate and are explicitly excluded from Section 122 stacking.
Non-USMCA goods from Canada or Mexico: If goods do not meet USMCA rules of origin (insufficient regional value content, wrong tariff classification shift, no certificate of origin), they are NOT exempt. They face the standard 15% Section 122 surcharge. Documentation compliance is critical.
### Landed Cost Example: Canadian Auto Parts (USMCA-Compliant)
Consider a shipment of suspension components sourced from a Canadian manufacturer, customs value of $50,000, HTS 8708.80.
Without USMCA exemption (hypothetical): - Base MFN duty: 2.5% = $1,250 - Section 122 (15%): $7,500 - Total duties: $8,750 (17.5% effective rate)
With USMCA exemption confirmed today: - Base MFN duty: 0% (USMCA preferential rate for qualifying auto parts) - Section 122: $0 (USMCA exempt) - Total duties: $0
The exemption represents a $8,750 savings on a $50,000 shipment. For high-volume importers moving $5M/year in Canadian automotive goods, the annual duty exposure difference between qualifying and not qualifying for USMCA is roughly $875,000.
### Verifying USMCA Eligibility: What to Check Now
The indefinite extension increases the stakes for USMCA compliance. Importers who have been treating Mexican or Canadian origin loosely should take this opportunity to verify their documentation is in order.
Certificate of Origin: A valid USMCA Certificate of Origin (or the importer's certification of origin under the self-certification model) must be on file for each entry. CBP audits are increasing; ensure certifications cover the correct date ranges and are updated annually for ongoing shipments.
Rules of Origin: The product must meet the applicable rule of origin — typically a tariff classification change rule, a regional value content (RVC) threshold (usually 75% net cost or 60% transaction value for most goods), or a combination of both. Auto parts face particularly stringent requirements under USMCA's automotive rules. Verify that your supplier's RVC calculations are current and documented.
Country of Origin Marking: Goods must be properly marked with country of origin. For goods manufactured in Mexico or Canada using inputs from third countries, ensure the substantial transformation analysis supports Canadian or Mexican origin.
### Auto Imports Exemption Also Extended
The proclamation also extended the exemption covering automobile imports indefinitely. Passenger vehicles and light trucks from all origins had been granted a temporary exemption from the Section 122 surcharge when the tariff launched. That exemption, like the USMCA exemption, was originally set to expire April 2. Today's action keeps auto imports exempt through the Section 122 period. This is particularly relevant for importers of complete vehicles (HTS Chapter 87) and aftermarket automotive components that fall outside Section 232 scope.
### What the Indefinite Extension Does Not Change
It is worth being precise about what has not changed:
- The Section 122 rate remains 15%. No rate reduction occurred. - The Section 122 expiration remains July 24, 2026. Only Congress can extend it beyond 150 days. - Section 232 tariffs on steel and aluminum continue to apply at 50% to imports from all countries, including Canada and Mexico. The USMCA exemption does not override Section 232. - Section 301 tariffs on Chinese goods (25% on Lists 1–3, 7.5% on List 4A) are unaffected and continue to apply on top of Section 122 for Chinese-origin goods.
### What Importers Should Do Right Now
First, audit your USMCA certifications. If you have active shipments from Canada or Mexico and have not recently confirmed that your certificates of origin are current and that your products still qualify under USMCA rules, do that this week. A failed USMCA claim on a CBP audit means retroactive duty liability plus potential penalties.
Second, run your landed cost scenarios. If you are sourcing a product from multiple origins — for example, from both China and Mexico — now is an excellent time to quantify the duty differential. Use our Duty & Tariff Calculator to compare landed costs across origins side by side, using the same HTS code. The spread between Chinese-origin and Mexican-origin goods (Section 301 + Section 122 vs. zero) can easily exceed 40 percentage points.
Third, consider supply chain adjustments for goods currently importing from non-USMCA origins where Mexico or Canada manufacturing is feasible. The USMCA exemption eliminates Section 122 exposure entirely, while the Section 122 framework remains in place through at least July 24.
Fourth, watch July 24. If Congress does not act to extend Section 122 authority, all current Section 122 duties — including any that have been stacking on non-USMCA goods — would terminate. That would change the landed cost math significantly for importers from Vietnam, India, Germany, and other countries currently absorbing the 15% surcharge.
### Monitoring Going Forward
The USTR has also opened new broad Section 301 investigations targeting overcapacity in manufacturing sectors across 16+ countries, with a completion target aligned to the Section 122 expiration in late July 2026. These investigations could result in new permanent tariff actions that take effect when or shortly after Section 122 expires. Importers should track USTR dockets and Federal Register notices through mid-2026.

Frequently Asked Questions
Common questions about usmca exemption from section 122 tariff extended indefinitely
Are all goods from Canada and Mexico now exempt from Section 122?
Only goods that qualify for preferential treatment under USMCA are exempt. Goods that do not meet USMCA rules of origin are still subject to the 15% Section 122 surcharge. Proper certification of origin is required.
Does the USMCA exemption also cover Section 232 tariffs on steel and aluminum?
No. Section 232 tariffs on steel and aluminum apply to all countries including Canada and Mexico at 50%. The USMCA exemption only applies to Section 122. These are separate tariff programs.
When does the Section 122 tariff expire?
Section 122 has a statutory 150-day limit from the date of implementation (February 24, 2026), placing the expiration at July 24, 2026. Only an Act of Congress can extend it beyond that date.
How do I verify that my goods qualify for USMCA treatment?
You need a valid Certificate of Origin (or self-certification) and must confirm your product meets the applicable USMCA rule of origin — typically a tariff classification shift, a regional value content threshold, or both. Consult a licensed customs broker for a formal origin ruling if you are unsure.
