Brazil's Section 301: a 25% tariff built to outlast IEEPA
USTR's June 1, 2026 Brazil determination proposes a 25% tariff with sweeping exemptions. The real story is structural: with IEEPA struck down and Section 122 legally impaired, Section 301 is becoming the durable tariff workhorse, and Brazil shows it stretching into anti-corruption, platform compliance, digital market access, and environmental enforcement.

Brazil's Section 301 is a tariff built to outlast IEEPA, and to stretch what counts as "trade"
USTR's June 1, 2026 determination on Brazil reads, on its surface, like a conventional unfair-trade case: six investigated areas, affirmative findings in all six, a proposed 25 percent tariff. The more important point is structural. With the Supreme Court having struck down every IEEPA tariff on February 20, 2026, and the Section 122 bridge tariff already legally impaired at the Court of International Trade, Section 301 is becoming the administration's durable tariff vehicle, and the Brazil action shows what it is being asked to carry. It is among the first known Section 301 actions aimed directly at a country's anti-corruption enforcement, and among the first known to build a digital-trade prong around foreign court orders compelling US platforms to remove political content. The case is less a Brazil story than a preview of how far the "unreasonable" standard can travel.

What USTR actually found
The investigation, self-initiated on July 15, 2025 at the President's direction (docket USTR-2025-0043), covered six areas in USTR's own order: digital trade and electronic payment services; preferential tariffs; anti-corruption enforcement; intellectual property protection; ethanol market access; and illegal deforestation. On June 1, 2026, USTR determined Brazil's acts, policies, and practices in all six are actionable under Section 301(b).
One framing point will be quoted often, so it should be stated precisely. The operative statutory language is "unreasonable or discriminatory," but USTR rested most prongs (anti-corruption, IP, ethanol, deforestation, and digital trade) on the "unreasonable" limb alone. Only the preferential-tariffs prong is expressly characterized as "unreasonable or discriminatory." It is accurate to say USTR found Brazil engages in unfair practices that burden US commerce across all six areas. It is not accurate to say every prong was found "discriminatory." The "unreasonable" limb reaches conduct that, in the statute's words, is "not necessarily in violation of … the international legal rights of the United States" but is "otherwise unfair and inequitable." That standard is what lets corruption, court orders, and forest policy be fitted inside "trade."
The two prongs that break new ground
**Anti-corruption: a rare, possibly first, use.** No prior Section 301 action is known to have rested on a target country's failure to enforce its anti-bribery laws. USTR's finding leans on the OECD Working Group on Bribery's 2023 Phase 4 report, the September 2023 annulment of Operation Car Wash (Lava Jato) evidence by Justice Dias Toffoli, Brazil's falling Transparency International score (34/100 in 2024, its lowest since 2012), and reported harassment of Transparency International's Brazil chapter. The competitive-harm theory is that weak enforcement lets non-compliant firms underbid FCPA-bound US companies. This is the most novel prong in the case, and, strictly, an argument from absence: there is no contrary precedent in USTR's published case list, so it is best carried as the first known use rather than an absolute first.
**Digital trade and platform compliance.** The FRN's first and most detailed prong targets Brazilian court orders directing US platforms (X, Meta, and Google are named) to take down political content and suspend US residents' accounts, sometimes globally, while barring disclosure to affected users. It cites Rumble, suspended in Brazil since February 2025, and X, blocked from late August to October 2024 by Justice Alexandre de Moraes; X's access was restored only after it paid roughly $5 million in fines, with X's and Starlink's assets frozen and payment processors blocked. A second sub-prong targets Pix, the central bank's instant-payment system, on national-champion grounds.
This is not simply a free-speech claim, and framing it as one understates the sovereignty problem. What USTR has done is convert platform liability, court-order compliance costs, asset restrictions, payment blocking, and market-access risk into a Section 301 "burden on commerce" theory. The notice is also deliberately narrow in one respect: in a footnote, USTR declined, for now, to make an actionability finding on the Brazilian Supreme Court's June 26, 2025 ruling partially striking down Article 19 of the Marco Civil framework, or on Brazil's personal-data transfer restrictions. The digital finding therefore rests on specific court orders and penalties, not on the Supreme Court ruling or the data-localization regime directly. That reads as a deliberate hedge against the sovereignty objection: that the First Amendment binds the US government, not Brazil, and that a foreign state is under no obligation to host speech originating on US soil. Critics including Public Citizen have called the content-removal theory legally and diplomatically fraught; Lula has reframed the dispute as one of sovereignty over foreign digital platforms. The footnote suggests USTR is aware of that exposure.
The 25 percent rate is post-IEEPA engineering
The rate is best read against the ones it replaces. The April 2025 universal "reciprocal" IEEPA tariff was 10 percent. The Bolsonaro-related IEEPA tariff added under Executive Order 14323 (effective August 6, 2025) was 40 percent, stacking to a 50 percent cumulative rate. The proposed Section 301 rate is 25 percent, set between the two.
Both IEEPA rates lost their legal basis after Learning Resources. On February 20, 2026, the Supreme Court held 6-3 in Learning Resources, Inc. v. Trump, consolidated with Trump v. V.O.S. Selections, that IEEPA does not authorize the President to impose tariffs. Both Brazil IEEPA tariffs fell with it. Within hours the administration imposed a Section 122 tariff (10 percent, rising toward 15 percent), which itself drew a CIT ruling on May 7, 2026 invalidating it as to the named importer plaintiffs, a decision now on appeal, with other importers still liable in the meantime. Refunds of roughly $160 billion to $179 billion in collected IEEPA duties remain unresolved and will be litigated for years. This is why the Brazil 301 exists: it is the legally durable replacement vehicle, and at 25 percent it is leverage calibrated for a moment when the maximalist rates have been struck down and the bridge is contested.
The exemptions tell you it is calibrated for negotiation
The proposed action applies 25 percent to "all goods of Brazil," then exempts a sweeping list in the Annex: crude oil and petroleum products, coffee, beef and bovine offal, orange juice, cocoa, large numbers of fruits, nuts and spices, minerals and ores including iron ore, rare earths, fertilizers, organic and inorganic chemicals, and pharmaceuticals. The proposed exclusions also cover goods already subject to Section 232 (steel, aluminum, copper and derivatives; autos and parts), along with informational materials and donations. Wood pulp is effectively spared. This list is materially broader than EO 14323's IEEPA exemption Annex.
How much is exempt? A rough HTS-level screen against 2024 import values (about $42.3 billion in total Brazil-origin imports, per CRS and Census data) suggests a large majority of import value may be exempt, likely around three quarters. That figure should be carried as a Traverse estimate pending a line-by-line Annex match, not as a finding: no firm or think tank has published a Section-301-specific exempt share. The big swing factor is machinery and electrical machinery (HS 84/85, perhaps $4 billion to $5 billion combined), which are neither on the Annex nor under Section 232; on the likeliest reading they are covered, which pulls the exempt share down. The exemptions skew toward consumer-sensitive, inflation-driving goods (oil, coffee, beef, juice), the same categories the administration carved out of the IEEPA 40 percent in November 2025. That is cost-management, not maximal punishment.
The coverage choices are equally deliberate. Ethanol, a named grievance, is covered precisely because tariffing it advances the case. Stone and granite countertops (HS 68), footwear (HS 64), and machinery (HS 84/85) round out the likely-covered set. USTR's stated exemption logic in the FRN is internally consistent: it spares raw materials, goods that would cause economy-wide disruption, goods unavailable elsewhere, and goods whose tariffing would not contribute substantially to changing Brazil's behavior.
Where Section 301 is heading
The environmental prong is the thread to watch. USTR's Vietnam illegal-timber case (initiated October 2020, resolved by a 2021 agreement with no tariffs) was, in Ambassador Tai's words, "the first 301 investigation to address environmental concerns." Brazil's deforestation prong is the second environmental 301, but the first to pair an environmental harm with an actual tariff remedy, built on competitiveness harm to US timber, beef, and soy producers. The next step is already visible in the record: comments on the March 2026 overcapacity 301 urged USTR to act against "foreign pollution" that burdens US commerce, and the initiation itself cites "lax or inadequate environmental standards" abroad. The legal hook would again be the "unreasonable" limb. A USTR climate or pollution 301 would turn that from a projection into a live case, with the Brazil deforestation prong as the template.
The Brazil case is not isolated. USTR self-initiated a structural-overcapacity 301 on March 11, 2026 covering 16 economies across roughly 21 sectors, and a forced-labor 301 on March 12 covering 60 economies (the largest single 301 by country count), plus a new Vietnam IP investigation in late May. Treasury Secretary Bessent has said combining Sections 122, 232, and 301 "will result in virtually unchanged tariff revenue in 2026." Together they are the structural replacements for IEEPA, and are likely to produce country-specific tariffs near IEEPA magnitudes by roughly late July 2026.
What to do before July
The 25 percent action is a proposal, not final. USTR must still take responsive action by July 15, 2026 (twelve months from initiation), and an eleventh-hour bilateral deal could suspend it, as happened with the France digital-services-tax case and the Vietnam timber case. The near-term calendar: requests to appear due June 22; written comments due July 1; a Section 301 Committee hearing (held at the USITC) on July 6.
If your product is covered (ethanol, granite and stone, footwear, machinery, electrical equipment, or anything off the Annex and outside Section 232), file comments by July 1 and build the record around the FRN's own exemption criteria: that the good is a necessary raw material, that tariffing it causes supply dislocation, that it is unavailable from non-Brazil sources at reasonable price and quantity, and that tariffing it "would not contribute substantially" to changing Brazil's behavior. Company-specific cost and supply-chain evidence carries more weight than coalition letters and preserves standing for a later challenge.
If your product is exempt, monitor but do not assume permanence. Scope can shift between the proposal and the July 15 decision, and the four-year Section 301 sunset plus periodic review mean exemptions can be revisited. Re-engage on any Annex modification, any Brazilian retaliation (which could prompt a rate increase), or a negotiated US-Brazil framework that reshuffles coverage. And if you source from any economy named in either the 16-economy overcapacity 301 or the 60-economy forced-labor 301, map that exposure now: those dockets, not Brazil, are where the largest post-IEEPA tariff bill is most likely to land.
