SCOTUS Strikes Down IEEPA Tariffs 6-3, Trump Signs 15% Global Surcharge Under Section 122 — Ecuador's $6.6B Export Channel Faces New Uncertainty

SCOTUS Decision Reshapes US Trade Architecture

The US Supreme Court ruled 6-3 on February 20, 2026 that tariffs imposed under the International Emergency Economic Powers Act (IEEPA) are unconstitutional, finding that the statute — originally designed for financial sanctions and asset freezes — does not grant the executive branch authority to levy import duties. The majority opinion, joined by Justices across ideological lines, held that tariff authority remains vested in Congress under Article I of the Constitution.

The ruling immediately invalidated the reciprocal tariff structure that had imposed combined levies of up to 18.78% on certain Ecuadorian exports — comprising a 15% reciprocal tariff and a 3.78% countervailing duty (CVD) specifically targeting shrimp imports.

The Section 122 Pivot

Within hours of the ruling, President Trump signed an executive order invoking Section 122 of the Trade Act of 1974, which permits the president to impose tariffs of up to 15% for 150 days to address large and serious balance-of-payments deficits.

Action	Date	Mechanism	Rate
IEEPA tariffs struck down	February 20	SCOTUS ruling	0% (invalidated)
Section 122 global tariff signed	February 20	Trade Act of 1974	10%
Section 122 rate increased	February 21	Executive order amendment	15%
Effective date	February 24	Applied to all imports	15% global

The escalation from 10% to 15% within 24 hours signals the administration's intent to maximize the tariff ceiling under Section 122. Legal scholars note that the 150-day statutory limit creates a ticking clock — the surcharge expires in mid-July 2026 unless Congress acts to authorize a permanent replacement.

Impact on Ecuador's Export Portfolio

Ecuador's total merchandise exports to the United States reached $6.6 billion in 2025, representing a 30.3% year-over-year increase and making the US Ecuador's largest single-country trade partner. The new 15% blanket tariff applies across the full export basket.

Product	Est. Monthly US Exports	Previous Tariff (IEEPA)	New Tariff (Section 122)	Net Change
Shrimp	~$20 million	18.78% (15% + 3.78% CVD)	15% + 3.78% CVD*	-3.22%
Bananas	~$35 million	15% reciprocal	15%	Neutral
Cacao/chocolate	~$18 million	15% reciprocal	15%	Neutral
Cut flowers	~$12 million	15% reciprocal	15%	Neutral
Tuna	~$15 million	15% reciprocal	15%	Neutral

Note: The 3.78% CVD on shrimp was imposed separately under countervailing duty law and was not part of the IEEPA framework — it likely survives the SCOTUS ruling.

For shrimp exporters, the net tariff position may actually improve slightly if the IEEPA-specific reciprocal rate is replaced by the lower Section 122 blanket rate. However, the CVD component remains a separate legal question that the shrimp industry continues to contest through the US International Trade Commission.

Reciprocal Trade Agreement in Limbo

The timing creates acute uncertainty for the US-Ecuador Americas Reciprocal Trade (ART) agreement, which was finalized in late 2025 as one of the first bilateral trade deals under the Trump administration's reciprocal framework. Key questions include:

• Legal basis: The ART was negotiated under the assumption that IEEPA tariffs provided the baseline leverage. With that legal authority invalidated, the agreement's enforcement mechanism is unclear.
• Rate arbitrage: If Ecuador's ART preferential rates were designed to offset IEEPA levies, the Section 122 replacement may require renegotiation of specific tariff schedules.
• Congressional action: Any permanent trade deal must now secure Congressional approval, which was not required under the IEEPA executive authority framework.

Ecuador's Ministry of Production (MPCEIP) and the US Trade Representative's office have not issued formal statements on the ART's status following the SCOTUS ruling.

Broader Market Context

The SCOTUS decision affects all US trading partners simultaneously, creating a global recalibration:

| Country/Region | 2025 US Imports | Exposure | |---|---|---|---| | China | $438 billion | Highest exposure; separate tariff regime | | European Union | $553 billion | Major retaliation risk | | Mexico | $467 billion | USMCA provides partial shield | | Ecuador | $6.6 billion | Mid-tier; commodity-dependent | | Colombia | $14.8 billion | Regional competitor for US market share |

Ecuador's position is complex: while the country is a relatively small US trade partner in absolute terms, its commodity concentration means the tariff impact falls disproportionately on a handful of export sectors that employ hundreds of thousands of workers.

Legal Analysis: Section 122 Vulnerabilities

Constitutional law experts have identified several potential challenges to the Section 122 tariff:

• Balance-of-payments justification: Section 122 requires a finding of "large and serious" balance-of-payments deficits. The US trade deficit, while large, has existed for decades — courts may question whether it constitutes the emergency the statute envisions.
• 150-day limit: The statute caps tariffs at 150 days, creating an automatic sunset in mid-July 2026. Extension requires Congressional action.
• 15% ceiling: Section 122 caps tariffs at 15%, meaning the administration cannot escalate rates further without a different legal basis.
• WTO compatibility: Global blanket tariffs may violate Most Favored Nation principles under WTO rules, inviting retaliatory measures.

Ecuador's Strategic Position

Ecuador faces a bifurcated risk scenario:

Scenario	Probability	Ecuador Impact
Section 122 tariff expires in July, no replacement	Low	Positive — tariff-free window
Congress passes permanent tariff legislation	Medium	Depends on Ecuador exemptions/rates
Section 122 challenged and struck down	Medium	Temporary positive, then uncertainty
ART renegotiated under Congressional authority	Medium-High	Potential for better terms if bipartisan

The Federacion Ecuatoriana de Exportadores (Fedexpor) has urged the government to accelerate direct negotiations with US congressional trade committees, bypassing the now-weakened executive tariff authority.

What to Watch

Track the Section 122 legal challenges — at least three lawsuits are expected within weeks, potentially reaching the Supreme Court on an expedited basis. Monitor USTR statements on ART status — any indication the bilateral deal requires renegotiation would signal months of additional uncertainty for Ecuadorian exporters. Watch Congressional trade legislation — several bills proposing permanent tariff frameworks are circulating in the Senate Finance Committee. Track shrimp CVD proceedings — the countervailing duty on Ecuadorian shrimp operates independently of the IEEPA/Section 122 framework and remains a significant cost burden for the aquaculture sector. Monitor Ecuadorian export volumes in March-April 2026 — the first months under the new tariff regime will reveal whether buyers accelerated purchases ahead of the February 24 effective date or are redirecting supply chains.
