Liberation Day Tariffs: One Year Later — What Importers Learned the Hard Way

What Actually Happened on April 2, 2025

The White House had telegraphed a major trade action for weeks, but the scale of what came on April 2, 2025 still caught most importers off guard. President Trump signed an executive order invoking the International Emergency Economic Powers Act (IEEPA) — a national security statute originally designed for sanctions and asset freezes, not tariffs — to impose the broadest set of new import duties in the modern era.

The legal mechanism was novel and immediately controversial. IEEPA grants the President expansive authority to regulate international commercial transactions during a declared national emergency. The Trump administration had declared an economic emergency based on persistent U.S. trade deficits, which it argued constituted an "unusual and extraordinary threat" to national security and the economy — the statutory threshold IEEPA requires.

The tariff structure had two layers. First, a universal 10% baseline tariff applied to all imports from all countries worldwide, effective April 5, 2025 — three days after the announcement. This was historic: no administration had ever applied a universal tariff to all countries simultaneously using executive authority. Second, higher country-specific "reciprocal" rates were announced for major trading partners, effective April 9, 2025. These were framed as matched responses to the tariffs those countries charged on U.S. exports — hence "reciprocal." The actual rate methodology, critics noted, bore little relationship to trading partners' actual tariff schedules, but the legal authority to set them did not require economic precision.

The 90-Day Pause — What It Meant and What It Did Not

Seven days after Liberation Day, on April 9, 2025, the administration announced it was pausing the higher country-specific reciprocal rates for 90 days for most trading partners — while explicitly excluding China. The markets responded with a historic single-day rally. For importers, the picture was more complicated.

During the 90-day pause, importers from paused countries paid the 10% universal baseline only, not the higher country-specific rate. This was significant for EU and Vietnamese goods, where announced rates of 20% and 46% respectively were paused back to the baseline 10%. But the pause did not eliminate the baseline — and 10% on top of existing MFN rates was still a substantial new cost for many product categories.

China was not paused. Chinese goods faced the full escalating rate schedule: initial 34% IEEPA duties that quickly escalated to higher levels in subsequent executive actions as a trade negotiation escalated. Importers of Chinese goods paid effective tariff rates of 145% or more on many products throughout 2025.

The pause also created an operational problem: uncertainty. Importers could not confidently model their full-year duty costs. Purchasing decisions froze. Supply chain diversification accelerated but couldn't be completed in 90 days. When the pause expired, most country-specific rates resumed — though bilateral negotiations produced partial agreements with some partners that modified individual rate schedules.

Lesson One from Year One: The pause taught importers that tariff rates can change on days or weeks of notice. Companies that had locked in long-term supplier contracts without tariff adjustment clauses found themselves absorbing costs they could not pass through. Build contractual tariff flexibility into all supply agreements going forward.

The CIT Court Battles — Section 122 and IEEPA Challenges

Legal challenges to the Liberation Day tariffs began within weeks of the executive order. The primary battleground was the U.S. Court of International Trade (CIT), which has exclusive jurisdiction over customs and trade law matters.

The core legal argument was deceptively straightforward: the Constitution grants Congress, not the President, the power to lay and collect duties (Article I, Section 8). IEEPA, challengers argued, does not and cannot transfer this constitutional power to the executive branch. Invoking IEEPA to impose tariffs on trade deficits — an ordinary economic condition, not an emergency — exceeded the statute's scope.

The CIT agreed. The court found that IEEPA's authority to "regulate...importation or exportation" of goods did not encompass the power to levy tariffs, and that in any event the declared emergency — a trade deficit — did not qualify as an "unusual and extraordinary threat" as required by the statute. The court ordered CBP to stop collecting IEEPA tariffs and issued injunctive relief.

The Department of Justice sought an emergency stay from both the Federal Circuit and the Supreme Court. The Federal Circuit declined. The Supreme Court granted a temporary administrative stay while it reviewed the case — keeping duties flowing for several additional months — before ultimately affirming the CIT's ruling in its decision in Learning Resources v. Trump. The ruling established the constitutional basis for the refund claims that importers can now pursue.

Lesson Two from Year One: The courts remain a viable check on executive tariff authority, but litigation takes time — and during that time, importers keep paying. The fastest protection remains proactive filing: protest every liquidated entry within the 180-day window, preserving your refund rights while litigation proceeds.

Current Tariff Status — Where Things Stand on April 2, 2026

As of the one-year anniversary, the tariff landscape looks like this:

• • IEEPA reciprocal tariffs: Declared unconstitutional; CBP collecting refunds under court order on valid protest claims
• • Universal 10% baseline: Also under the IEEPA order; subject to the same refund right
• • Section 301 China tariffs: Remain fully in force; separate legal authority; no refund right from IEEPA ruling
• • Section 232 steel and aluminum: Remain in force; separate legal authority; separate refund analysis required
• • Country-specific bilateral deals: Several trading partners reached partial agreements during the 90-day pause and its extensions; specific product exclusions negotiated may affect classification and duty rates
• • New executive tariff actions: The administration has pursued alternative tariff mechanisms under other legal authorities; importers should monitor HTS schedules for new tariff lines

The key practical point: the IEEPA ruling created a refund right, not automatic refunds. You must affirmatively file a CBP Form 19 protest within 180 days of each entry's liquidation to preserve your claim.

Five Hard Lessons from Year One — and What to Do About Them

Lesson 1: File CBP Protests Immediately — Refund Claims Are Time-Barred

The single most costly mistake importers made in Year One was failing to file CBP protests promptly after the Supreme Court ruling. Under 19 USC 1514, the protest deadline is 180 days from an entry's liquidation date — and it is absolute. There are no exceptions for ongoing litigation, financial hardship, or good-faith ignorance.

On April 2, 2026, entries liquidated in October 2025 have protest deadlines expiring this week. November and December 2025 entries still have open windows — but they are closing fast. Do not wait for perfect documentation or legal certainty. File the protest now to preserve your rights; supporting documentation can follow in supplemental submissions.

Use our Refund Impact Estimator to prioritize which entries to protest first based on duty amount and window urgency.

Lesson 2: Duty Drawback Is Underutilized

Duty drawback under 19 USC 1313 refunds up to 99% of duties on goods that are subsequently exported. Despite being one of the most powerful tariff recovery tools in the U.S. Customs toolkit, most importers either do not know about it or have not pursued it systematically.

Year One created massive drawback opportunities. Manufacturers that imported components subject to IEEPA duties, incorporated them into finished products, and exported those products are likely eligible for manufacturing drawback. Retailers that imported merchandise, could not sell it domestically, and exported it are eligible for unused merchandise drawback.

Drawback claims have a three-year filing window from import — so 2025 entries remain fully eligible. See our Duty Drawback Calculator to estimate your drawback refund potential before you engage a drawback specialist.

Lesson 3: Tariff Classification Can Legally Reduce Your Duty Bill

Many importers used HTS classifications suggested by suppliers or applied by customs brokers under time pressure — not classifications that minimized duty exposure within legal limits. A formal tariff classification review by a licensed customs attorney frequently identifies lower-rate alternatives that are legally defensible.

Classification opportunities differ by product: components may qualify differently than finished goods; multi-function products may be classifiable under the provision with the most essential function; goods with U.S. content or manufacturing may qualify for reduced rates under specific rules of origin.

For past entries where a more favorable classification is available, an amended entry or prior disclosure can recover excess duties paid — subject to time limitations. For current and future entries, an upfront classification review pays for itself many times over at elevated tariff rates.

Lesson 4: First-Sale Valuation Reduces the Base on Which Tariffs Are Calculated

Tariffs are calculated as a percentage of the declared customs value. The lower the declared value, the lower the tariff dollar amount — even at identical tariff rates. The first-sale valuation method (19 CFR 152.103) allows importers in multi-tier supply chains to declare the earliest transaction price rather than the final price paid to their supplier.

For example: a Chinese manufacturer sells goods to a Hong Kong trading company for $50/unit. The trading company sells to a U.S. importer for $70/unit. Under standard transaction value, duties apply to $70. Under first-sale valuation, duties apply to $50 — a 29% reduction in the dutiable base. At a 145% effective tariff rate on Chinese goods, this difference is enormous.

First-sale valuation requires documentation: commercial invoices at both tiers, proof of payment, evidence that the first-sale was an arms-length transaction destined for U.S. export. Many importers failed to maintain this documentation in 2025. Going forward, establish documentation practices at origin before goods ship.

Lesson 5: Free Trade Zones Provide Structural Tariff Advantages

Foreign Trade Zones (FTZs) are federally designated areas where goods may enter the United States under CBP supervision without being formally "imported" until they leave the zone for U.S. commerce. Key advantages:

• • Duty deferral: No duty payment until goods enter U.S. commerce — cash flow advantage for large inventories
• • Inverted tariff relief: Manufacture finished goods in the FTZ; pay the finished-goods tariff rate rather than the higher component rate (or vice versa, whichever is lower)
• • Re-export exemption: Goods re-exported from an FTZ pay no U.S. duties
• • Merchandise processing fee reduction: FTZ weekly entry procedures reduce MPF costs for high-volume importers

Many high-volume importers accelerated FTZ applications in the wake of Liberation Day. While establishing FTZ status takes time, working with an existing FTZ operator (most major ports have activated FTZ operators) can begin providing benefits within weeks.

Note: the de minimis exemption under Section 321 — which allows $800-or-under shipments to enter duty-free — was significantly complicated by Liberation Day orders, particularly for Chinese-origin goods. See our De Minimis Exemption Calculator for current eligibility analysis.

Your Practical Action Plan — Right Now

Looking Ahead — Tariff Risk Management for Year Two

Liberation Day did not end tariff risk — it transformed it. The lesson of Year One is not that the tariff threat has passed. The Supreme Court ruling resolved IEEPA. It did not resolve Section 301 authority, Section 232 authority, or whatever new legal mechanisms an administration might invoke under renewed national emergency declarations.

The importers who came through Year One in the best position were not those who predicted the tariff landscape correctly — no one did. They were the ones who had systems in place: classification reviews that ensured they weren't overpaying, first-sale documentation practices that reduced their dutiable base, FTZ access that gave them structural flexibility, and drawback programs that systematically recovered duties on exports.

These are not crisis responses. They are ordinary good practice that becomes essential during tariff shocks. If Liberation Day did not force you to implement them, use Year Two to get there before the next one.
