The July 24 Tariff Cliff: What Happens When Section 122 Expires

In nine days, the 10% global tariff that's hit every import since February disappears — by operation of law, not by choice. But if you think your duty bill is about to drop, think again. The administration has spent five months building replacement tariffs under Section 301 and Section 232 that are broader, higher, and permanent. Here's exactly what's changing, what's replacing what, and what you need to do before July 24.

The number that matters right now is 150. That's the maximum number of days Congress allows a Section 122 balance-of-payments surcharge to remain in effect without explicit legislative extension. President Trump imposed the 10% global surcharge on February 24, 2026 — hours after the Supreme Court struck down his IEEPA tariff authority — and the constitutional clock started ticking immediately.

On July 24, 2026, that clock runs out. No extension legislation is pending. No executive workaround exists. The surcharge dies automatically at 12:01 a.m. EDT.

But here's what every importer needs to understand: the administration hasn't been sitting idle for 150 days. It's been building a permanent replacement tariff architecture using authorities that have no expiration date, no rate ceiling, and no 150-day clock. The Section 122 sunset isn't a reprieve — it's a transition.

The Legal Timeline: How We Got Here

The current tariff landscape is the product of an extraordinary six months of legal and executive action:

• February 20, 2026: The Supreme Court rules in State of New York v. Trump that IEEPA does not authorize tariff imposition. Approximately $166 billion in collected IEEPA duties are immediately in legal limbo.
• February 24, 2026: Within hours, President Trump imposes a 10% global surcharge under Section 122 of the Trade Act of 1974 — a balance-of-payments authority last used by President Nixon in 1971.
• April 2, 2026: The administration announces Section 232 tariffs of 100% on patented pharmaceuticals and APIs, effective July 31 for large manufacturers and September 29 for others.
• April 6, 2026: Section 232 metals tariffs are overhauled — steel, aluminum, and copper articles move to a flat-rate structure at 50% assessed on content value.
• May 7, 2026: The Court of International Trade rules Section 122 tariffs exceed statutory authority — but limits relief to named plaintiffs only. The tariffs remain in effect for everyone else.
• June 2, 2026: USTR announces proposed Section 301 tariffs on 60 countries (10-12.5%) based on forced labor enforcement failures. Public comments closed July 6; hearing held July 7.
• July 24, 2026: Section 122 expires by operation of law.

What Section 301 Replaces: The Forced Labor Framework

The most significant replacement for Section 122 is USTR's proposed Section 301 action targeting 60 countries — including major trading partners like Canada, the EU, Mexico, Japan, and South Korea — for allegedly failing to enforce prohibitions on forced-labor-produced goods.

The proposed rates break into two tiers:

Key exemptions (listed in USTR's Annex A):

• Agricultural products
• Aviation parts and equipment
• Industrial inputs and minerals
• Pharmaceutical goods
• Goods already subject to Section 232 tariffs

Unlike Section 122, Section 301 tariffs carry no statutory expiration date and no rate ceiling. Once imposed, they remain until the President determines the underlying trade practice has been eliminated — which, in past Section 301 cases (like the China tariffs imposed in 2018-2019), has meant years or decades.

No specific effective date has been announced, but multiple law firms — including Thompson Coburn, Dorsey & Whitney, and Crowell & Moring — expect these tariffs to coincide with the Section 122 sunset on July 24.

Section 232: The Pharma Tariff Shock

Running in parallel is a separate Section 232 action that imposes 100% ad valorem tariffs on patented pharmaceuticals and active pharmaceutical ingredients (APIs) — the steepest Section 232 rate ever applied to a product category.

Companies that executed Most Favored Nation (MFN) agreements before April 2, 2026, are exempt entirely — making tariff exposure a function of company-level deal status rather than country of origin.

The Commerce Department found that 53% of patented pharmaceutical products distributed domestically are manufactured abroad, with only 15% of patented APIs produced in the United States. That finding underpins the national security rationale.

The IEEPA Refund Pipeline: $166 Billion in Play

While new tariffs stack up, the refund process for the struck-down IEEPA tariffs is finally gaining momentum. CBP's Consolidated Administration and Processing of Entries (CAPE) system is now processing refunds in two phases:

Phase 1 (launched April 20, 2026):

• Covers unliquidated and recently liquidated entries
• Accessible through the ACE Secure Data Portal
• CBP estimates processing within 45-60 days of accepting a CAPE Declaration
• Covers approximately 63% of eligible entries

Phase 2 (launched June 29, 2026):

• Expands eligibility to reconciliation-flagged entries (types 01, 02, and 06)
• Only where related reconciliation entry (type 09) has not yet been filed
• Importers must file their reconciliation entry after CAPE acceptance

Refunds are not automatic. You must actively file a CAPE Declaration through ACE. CBP has stated refunds "will generally be issued within 60-90 days following acceptance," though compliance reviews can extend that timeline.

If you paid IEEPA tariffs between April 2, 2025 (when they first took effect) and February 20, 2026 (when the Supreme Court struck them down), you are likely eligible. The total pool is estimated at $166 billion across all importers of record.

The Net Effect: What Your Duty Bill Looks Like After July 24

Here's the math that matters. For a typical importer bringing goods from a Tier 2 Section 301 country (say, Vietnam or India) that isn't covered by a specific exemption:

For most importers, the replacement tariffs are higher than what they replace. The Section 122 surcharge was 10% across the board. The Section 301 replacement is 10-12.5% — and unlike Section 122, it stacks on top of existing Section 232 duties for metals, with no anti-stacking executive order covering the new framework.

Country-Specific Section 301 Investigations: Vietnam and Beyond

Beyond the broad 60-country action, USTR has initiated targeted Section 301 investigations that could layer additional tariffs on specific trading partners:

• Vietnam (initiated May 29, 2026): Investigating persistent failures in intellectual property protection and enforcement
• Additional country-specific actions: Expected based on USTR's stated framework of bilateral trade negotiations

These investigations run on independent timelines and could result in country-specific tariff rates significantly exceeding the baseline 10-12.5%.

What Importers Must Do Before July 24

You have nine days. Here's your action list:

1. File your CAPE Declaration now — If you paid IEEPA tariffs and haven't filed, you're leaving money on the table. Access the CAPE system through your ACE Portal account. Phase 2 expanded eligibility on June 29, so entries previously ineligible may now qualify.

2. Audit your HTS classifications for exemption eligibility — The Section 301 proposal includes specific product exemptions in Annex A. If your goods fall under aviation parts, industrial inputs, minerals, or pharmaceutical categories, you may be exempt from the replacement tariffs. Proper classification is the difference between 0% and 12.5%.

3. Map your supply chain to the two-tier country list — Know whether each sourcing country falls in the 10% or 12.5% tier. This changes your landed cost calculations immediately upon the Section 301 effective date.

4. Check Section 232 exposure for pharma — If you import patented pharmaceutical products or APIs, the July 31 effective date for large companies is one week after Section 122 expires. Review whether your products qualify for exemptions (generics, orphan drugs, cell/gene therapies) or reduced rates (approved onshoring plans).

5. Review anti-stacking provisions — The April 2025 executive order removing tariff stacking applied to the IEEPA/Section 122 regime. It is unclear whether this protection extends to the new Section 301 framework. Plan for the worst case: full stacking of Section 301 + Section 232 + MFN duties.

6. Document everything for potential future refund claims — The CIT struck down Section 122 tariffs as exceeding statutory authority on May 7, but relief was limited to named plaintiffs. If the Federal Circuit affirms on appeal, nationwide refund eligibility could follow — but only for importers who can document their entries.

What's Coming Next

The July 24 expiration is not an endpoint — it's the starting gun for a permanent tariff regime:

• July 31, 2026: Section 232 pharma tariffs take effect for large companies (100% on patented drugs and APIs)
• Late July/Early August: Section 301 forced labor tariffs expected to take effect (10-12.5% on 60 countries)
• September 29, 2026: Section 232 pharma tariffs take effect for smaller manufacturers; reduced 20% rate begins for companies with approved onshoring plans
• Fall 2026: Vietnam-specific Section 301 investigation results expected
• Ongoing: CAPE Phase 3+ for remaining IEEPA refund entries (reconciliation entries already filed, drawback claims)

The administration has also established a Board of Trade to manage U.S.-China trade relations separately, suggesting China-specific tariff rates will continue to operate outside the broader framework.

The Bigger Picture

What's happening on July 24 is not a tariff reduction — it's a tariff transformation. The temporary, legally vulnerable Section 122 surcharge is being replaced by permanent authorities that have survived decades of legal challenges. Section 301 has been upheld by the Federal Circuit. Section 232 has been upheld by the Supreme Court. The new framework is built to last.

For customs brokers and importers, this means the compliance challenge is actually increasing. Instead of one flat 10% surcharge, you're now navigating country-specific tiers, product-specific exemptions, company-level MFN agreements, and potential stacking across multiple programs. Classification accuracy has never mattered more — because the wrong HTS code doesn't just change your duty rate, it determines which tariff programs apply at all.

TariffLens tracks all active tariff programs and maps them to your specific HTS classifications, so you can see exactly which duties apply to every product in your portfolio as the framework shifts.
