USMCA nonrenewal does not move the tariff schedule by itself
The July 1 statement keeps the matter on the Article 34.7 review track, and the agreement stays in force while the parties keep talking. A later Article 34.6 withdrawal notice would open a separate international clock, but neither the nonrenewal nor a future notice rewrites the tariff schedule on its own. What an importer pays at entry runs through General Note 11, and that line does not change until a domestic instrument changes it.
So the nonrenewal alone does not terminate USMCA preferential tariff treatment, and it does not lock that treatment in either. Withdrawal, the statutory lapse Congress wrote into the implementing act, an amendment to the tariff schedule, and the way Customs administers entries are separate steps that collapse into one only if Section 621 is read as self-executing, and that reading is contested. If a later withdrawal or termination occurs, the entry treatment will turn on the effective date of termination, Section 621, any HTSUS modification or proclamation, CBP implementation guidance, and the liquidation posture of the relevant entries. Until then, General Note 11 remains the line an importer claims at entry, which makes it an entry, pricing, and protest question well before it becomes a merits holding.
The July 1 statement is a nonrenewal rather than a withdrawal notice
On July 1, 2026 the Office of the U.S. Trade Representative said the United States would not renew the U.S.-Mexico-Canada Agreement in its current form at the first six-year joint review, and said the agreement remains in force pending resolution or termination. That statement runs on the Article 34.7 joint-review track rather than the Article 34.6 withdrawal track, and the two provisions carry different clocks and different domestic consequences. Treating the nonrenewal as a withdrawal is the first mistake to avoid.
Nothing in the statement identifies an Article 34.6 withdrawal notice. If one is filed later, it becomes a separate event that starts the six-month international clock, and even then it does not change the tariff schedule by itself. The question a customs practitioner has to answer is narrower than the political story. Should the President file a notice, or should the process run to a point where the agreement ceases to be in force, does duty-free treatment under General Note 11 end on its own, and can the President end it without Congress. That answer is unsettled, and it drives entry posture, contract drafting, and any refund path an importer might later assert.
The preference sits in the tariff schedule
Congress approved the agreement and its statement of administrative action in the USMCA Implementation Act, Public Law 116-113. The statute defines preferential tariff treatment as the customs duty rate that applies to an originating good of a USMCA country, and it grants the President proclamation authority to carry the agreement into the tariff schedule through duty reductions, continued duty-free treatment, and rules of origin, subject to consultation and layover conditions.
The President used that authority in Proclamation 10053, which modified the Harmonized Tariff Schedule to insert USMCA duty treatment and rules of origin and to reflect the end of NAFTA tariff treatment. What survives today is General Note 11, the part of the tariff schedule that sets the origin rules a good must meet to qualify. The preference an importer claims at entry is therefore a domestic tariff-schedule position, produced by a proclamation and resting on a statute. The agreement is the international instrument and General Note 11 is the domestic one, and the two can move apart.
The treaty exit and the tariff line run on separate tracks
Article 34.6 lets any party withdraw on six months written notice, and the agreement stays in force for the remaining parties. Article 34.7 sets the separate six-year joint review and the term-extension mechanics. Both appear in the USMCA Final Provisions text. A withdrawal notice starts the international clock, but it does not by its own text amend the tariff schedule or remove General Note 11 from domestic law. The importer-facing rate is a schedule position, and the open question is whether Section 621 changes that position when the agreement ceases to be in force or whether a further HTS instrument is still needed.
That separation is not a debating point. It runs through the position an importer actually asserts at entry, which depends on General Note 11 and the origin basis available on the entry date. Customs reads the tariff schedule and any valid instruction that implements it, rather than the treaty text. The importer's strongest position is that a change in international status should not decide a filed entry until a valid domestic instrument changes the schedule or directs Customs to administer the lapse. Which instrument governs the entry decides what the filer may lawfully claim on the day the entry is made, and it shapes whether a later protest or refund claim has a schedule position to stand on.
Section 621 is where the government and the importer divide
Section 621 of the implementing act writes two statutory termination rules. One runs when a country ceases to be a USMCA country. The other runs when the USMCA ceases to be in force with respect to the United States, and on that date the Act and the amendments it made, apart from carved-out provisions, cease to have effect. That second rule is the government's strongest card, because it supports the argument that once the agreement is no longer in force, the statutory basis for USMCA tariff treatment falls away without a new enactment.
The importer's answer is narrower and turns on what Section 621 leaves out. It does not name an HTS amendment, a liquidation rule, or a CBP filing instruction, and the implementing statute elsewhere uses proclamation mechanics for tariff and origin changes. Section 621 makes the unilateral path more plausible than treaty text alone, but it does not by its terms rewrite the schedule, and that gap is what a challenge would turn on.
Timing sharpens the point, because an Article 34.6 notice and the Section 621 date are different events. The notice starts the international clock, while Section 621 speaks to the later date on which the agreement ceases to be in force. A filing instruction issued during the notice period would have to say whether Customs is being told to prepare for a future lapse, to change treatment at once, or to change treatment only after a completed withdrawal, and each of those is a different entry position. The same split appears at liquidation. An importer that keeps claiming USMCA treatment while General Note 11 still sits in the schedule is not ignoring the withdrawal process. It is taking the position that the schedule supplies the filing rule until a valid instrument changes it, and the statutory lapse still has to be administered through the schedule and Customs guidance before it can decide a live entry.
Section 125 supplies a model of separate clocks
Section 125 of the Trade Act of 1974 lets the President terminate a proclamation made under the Trade Act chapter, and for agreements within its coverage it keeps duties and import restrictions in effect for one year after termination or withdrawal unless the President restores rates by proclamation. Whether that power reaches a proclamation issued under the USMCA statute rather than under the Trade Act chapter is a real question, because the authority for Proclamation 10053 runs through the implementing act.
Section 125 does not decide the USMCA result, and it should not be read as an automatic one-year survival rule for USMCA preferences. Its value is structural. It shows that Congress has, in other settings, let agreement termination and domestic tariff treatment run on different clocks, which supports the importer's sequencing argument without settling whether Section 621 supplies a different rule here.
Learning Resources raises the bar on thin tariff authority
Learning Resources, Inc. v. Trump held that the International Emergency Economic Powers Act does not authorize the President to impose tariffs. The Court treated the tariff power as part of Congress's taxing power and rejected the government's reliance on IEEPA's regulate-importation language. The decision does not reach Section 621, Section 125, General Note 11, or USMCA withdrawal, so it is not controlling here. It matters because it makes a thin tariff-authority chain harder to defend when the practical result is a duty increase, and an importer that suddenly lost General Note 11 treatment would have a live argument that the increase needs a clear domestic authorization and cannot rest on the withdrawal decision alone.
If the preference does end, the baseline is not a single published number. Canadian and Mexican originating goods would fall outside any USMCA-specific preference and would look to the tariff schedule's General rates, plus any independent trade-remedy measures then in force. The duty change for a given importer should be modeled from that importer's own tariff lines, origin status, and applicable measure stack rather than from an average-rate proxy.
The Section 122 surcharge is a separate question
Section 122 of the Trade Act of 1974 caps a temporary import surcharge at 15 percent ad valorem for a period that may not exceed 150 days unless Congress extends it. That ceiling is the fixed point. The live application in 2026 is Proclamation 11012, which imposed a 10 percent ad valorem surcharge for 150 days, effective February 24, 2026 through July 24, 2026. That proclamation matters here for one reason. It excludes articles entered free of duty as a good of Canada or Mexico under General Note 11, so the current surcharge regime leans on the same tariff-schedule line this analysis turns on.
The surcharge has also been challenged in court, and any importer relying on the current surcharge posture should confirm the operative court orders and CBP guidance before pricing an entry. Beyond the statutory cap, the effective dates, and the General Note 11 exclusion set out above, any further claim about the surcharge rate, scope, or enforceability needs the operative proclamation and the implementing CBP guidance.
Section 621 is what makes this new
The joint-review outcome is not what makes this worth watching. The new element is that Section 621 hands the government a statutory lapse argument that treaty text alone would not supply. Because the Act and its amendments cease to have effect when the agreement ceases to be in force with respect to the United States, unilateral termination is more plausible than it looks from the treaty side. That same text also exposes the fight, because the tariff schedule still moved through a proclamation, and the question of what instrument Customs applies at entry does not answer itself.
What an importer should do before the schedule moves
USMCA withdrawal and the end of General Note 11 treatment are separate analytical steps, even if the government argues that Section 621 makes them coincide once the agreement ceases to be in force. Section 125's separate-clock model and the clear-authority pressure from Learning Resources keep automatic tariff reversion a litigation-grade question rather than a settled outcome, so an importer should not assume the preference disappears the day a notice is filed and should not assume it is safe either.
The practical work follows from that uncertainty. Re-confirm origin qualification and tariff classification on the lines that depend on General Note 11, because a preference fight is won or lost on whether the good actually qualified. Model the duty exposure on those lines against the General rates and the independent measure stack so the downside is a number rather than a guess. Review force majeure, change-in-law, and duty-allocation clauses, because drafting rather than the tariff schedule decides which party carries a mid-stream duty increase. Preserve entry documentation and watch the liquidation and protest windows, because a preference that is removed and later restored, or removed without valid domestic authority, is recovered through timely protests and preserved entries. Track the Federal Register, USTR, and CBP for any proclamation or implementation notice, because the domestic instrument rather than the treaty notice is what actually moves the rate.
Two files carry most of that weight. The origin file has to show the good met General Note 11 on the entry date, which answers the product-specific compliance question. The legal file has to preserve why the importer believed the domestic schedule still controlled the entry, which answers the government-action question and supports a protest or refund if Customs later denies the preference on withdrawal grounds rather than on qualification. A contract clause that assigns duties only when goods fail to qualify may say nothing about who pays if the goods still qualify but the preference is gone, so the clause should treat classification change, origin determination, new duty imposition, loss of preference, and refund recovery as separate events.
What would turn planning into entry exposure
A written Article 34.6 notice would move the issue from planning to exposure. A Federal Register proclamation that cites Section 621, Section 125, or both would become the domestic trigger to analyze. A CBP implementation message would show the entry treatment importers must follow at filing. A Federal Circuit ruling on General Note 11 termination would supply controlling appellate law, while a CIT ruling would be important authority and binding at least as to the case before it, with its broader reach depending on posture and appeal.
The hardest posture arrives if the government issues no domestic tariff instrument at all. The challenge then is not only whether the United States has withdrawn from the agreement. It is whether Customs may disregard the tariff schedule entry position without a valid domestic change to the schedule. The form of any instrument matters too. A proclamation that modifies the schedule under the implementing act tests whether Section 621 and that act supply the modification power once the agreement is no longer in force, while a proclamation that reaches the same goods under a separate tariff authority tests whether that independent statute can carry the rate change on its own. An importer that reads only the headline rate would miss the authority question that decides how durable the change is and whether a refund path survives.
Timing against liquidation is the last variable. Entries filed during the notice period, entries filed after a completed withdrawal, and entries filed after a domestic instrument takes effect sit in different postures. The date of entry, the date of the instrument, and the date the agreement ceases to be in force each bear on whether a given entry keeps General Note 11 treatment or loses it, and mapping those dates against the liquidation calendar is what turns the legal question into an entry-by-entry exposure.
Caveats
The confirmed facts here are limited to the official records linked in this draft, which are the USMCA Final Provisions text, the USMCA Implementation Act, Proclamation 10053, the tariff schedule, the Learning Resources holding, the statutory text of Sections 122 and 125, Proclamation 11012, and the July 1 USTR statement. The interpretive claims are the separation of the treaty notice from the tariff line, the two-rule reading of Section 621, the structural use of Section 125, and the importer reading that a valid domestic tariff instrument remains necessary.
The inferences are the read-across from Learning Resources to Section 621 and the likely non-preferential rate baseline. Publication risk covers any current Section 232 rate, any Section 122 detail beyond Proclamation 11012 and its General Note 11 exclusion, current utilization figures, average effective-rate figures, and any litigation reference not tied to a docket or order. The official materials reviewed here identify the July 1 action as a joint-review nonrenewal with the agreement remaining in force and do not identify an Article 34.6 withdrawal notice, and that point should be rechecked against USTR, the White House, the Federal Register, and CBP before approval.
