The Section 232 Semiconductor Tariff: What Importers and Tech Companies Need to Know

What Is the Section 232 Semiconductor Tariff?

The Section 232 semiconductor tariff is a 25% ad valorem duty imposed on certain advanced computing chips imported into the United States. Issued under Proclamation 11002 on January 14, 2026, it targets a narrow category of high-performance semiconductors — specifically those meeting defined Tensor Processing Performance (TPP) and DRAM bandwidth thresholds — that the Commerce Department determined are imported in quantities threatening U.S. national security.

Who Does the Section 232 Semiconductor Tariff Affect?

The tariff primarily affects importers of advanced AI accelerator chips — such as the NVIDIA H200 and AMD MI325X — along with their derivative assemblies. However, broad exemptions exist for U.S. data centers, startups, R&D operations, and public sector applications, meaning the practical impact falls on a narrow slice of commercial imports that do not qualify for these carve-outs.

The 25% tariff on advanced AI semiconductors is the first product-specific Section 232 action targeting the chip industry. Unlike the blanket steel and aluminum tariffs of 2018, this measure is surgically scoped: it covers only chips meeting precise technical parameters, while exempting most end-use categories that support domestic AI infrastructure buildout.

For importers, compliance teams, and technology companies, the challenge is not just understanding the tariff rate — it is determining whether a specific product falls within the covered technical thresholds, whether an exemption applies, and how to document the end-use claim in a way that survives CBP scrutiny.

How the Section 232 Semiconductor Tariff Works

The Legal Foundation

On April 1, 2025, the Secretary of Commerce initiated a Section 232 investigation into the effects of semiconductor imports on U.S. national security. The Semiconductor Industry Association, ITIF, and dozens of industry stakeholders submitted public comments during the May 2025 comment period.

On December 22, 2025, the Secretary transmitted the final report to the President, concluding that semiconductors, semiconductor manufacturing equipment, and their derivative products "are being imported into the United States in such quantities and under such circumstances as to threaten to impair the national security of the United States."

Three weeks later, President Trump issued Proclamation 11002, imposing a 25% tariff effective January 15, 2026. The White House fact sheet identified NVIDIA H200 and AMD MI325X devices as examples of covered products.

Two-Phase Approach

The proclamation establishes a two-phase strategy:

Phase	Scope	Status
Phase 1 (Current)	25% tariff on narrow category of advanced AI chips meeting specific TPP/DRAM thresholds	Effective January 15, 2026
Phase 2 (Pending)	Broader tariffs on semiconductors, SME, and derivative products — with a tariff offset program for companies investing in U.S. manufacturing	Pending negotiation outcomes; April 14, 2026 update deadline

The Commerce Secretary recommended that the Phase 2 tariff be set "at a rate of duty that is significant" and accompanied by a tariff offset program enabling companies investing in U.S. semiconductor production to obtain preferential tariff treatment.

"The Secretary found that semiconductors, semiconductor manufacturing equipment, and their derivative products are being imported into the United States in such quantities and under such circumstances as to threaten to impair the national security of the United States." — Proclamation 11002, The White House

Which Products Are Covered by the Tariff?

The tariff does not apply to all semiconductors. It targets a technically defined subset of advanced computing chips classified under specific HTS subheadings.

Covered HTS Subheadings

Products are subject to the 25% tariff if they are classifiable under HTSUS subheadings 8471.50, 8471.80, or 8473.30 and contain logic integrated circuits meeting either of these technical parameter sets:

Parameter Set	TPP Range	DRAM Bandwidth Range
Set A	Greater than 14,000 and less than 17,500	Greater than 4,500 GB/s and less than 5,000 GB/s
Set B	Greater than 20,800 and less than 21,100	Greater than 5,800 GB/s and less than 6,200 GB/s

Chapter 99 Tariff Lines

CBP issued CSMS #67400472 with detailed guidance on entry filing. The proclamation created the following HTS 9903 subheadings:

HTS 9903 Code	Description
9903.79.01	Covered semiconductor articles subject to 25% tariff
9903.79.02	Articles classified under covered subheadings but NOT meeting technical parameters (exempt)
9903.79.03	Semiconductor articles for use in U.S. data centers
9903.79.04	Articles for repairs or replacements performed in the U.S.
9903.79.05	Articles for R&D in the United States
9903.79.06	Articles for use by U.S. startups (emerging growth companies)

GingerControl's Tariff Calculator covers the full U.S. tariff stack — base duty, Section 232, Section 301, Chapter 99, and Section 122 reciprocal tariffs across 200+ countries — so importers can model the complete duty impact of semiconductor shipments before they arrive at the port.

What Is NOT Covered

The tariff does not apply to:

Legacy chips (older-generation semiconductors below the TPP/DRAM thresholds)
Semiconductor manufacturing equipment (subject to Phase 2 consideration, not Phase 1)
Consumer electronics containing covered chips (the tariff applies to the chips themselves, not finished consumer products)
Chips imported for exempt end-uses (see next section)

What Exemptions Are Available?

The proclamation includes broad exemptions tied to end-use — meaning the same chip can be tariff-free or subject to 25% duty depending on how and where it will be used in the United States.

Exemption Category	HTS 9903 Code	Key Requirement
U.S. data centers (100+ MW)	9903.79.03	Must be used in a qualifying U.S. data center facility
Repairs and replacements	9903.79.04	Must be for servicing existing U.S. installations
R&D in the United States	9903.79.05	Must be used specifically for domestic research and development
U.S. startups	9903.79.06	Importer must qualify as an "emerging growth company"
Non-data-center consumer applications	—	Consumer devices not used in data center infrastructure
Non-data-center civil industrial uses	—	Industrial applications outside the data center context
U.S. public sector applications	—	Government and public sector end-uses

Documentation Is Critical

CBP mandates correct HTSUS sequencing, separate duty reporting for each applicable tariff line, and end-use certification to support exemption claims. Importers should:

Determine product coverage — Verify whether the imported semiconductor meets the TPP and DRAM bandwidth thresholds
Classify the end-use — Match the intended use to an exemption category and the corresponding HTS 9903 code
Build documentation — Prepare end-use certifications, purchase orders, and installation plans that demonstrate the exemption basis
Maintain audit trails — CBP and Commerce may scrutinize exemption claims; documentation must withstand review

How Does This Tariff Interact with Other Semiconductor Duties?

Advanced computing chips may be subject to multiple overlapping tariff layers. Importers must understand how the Section 232 tariff stacks with other duties:

Tariff Layer	Applicability to Semiconductors
Base MFN duty	Varies by HTS subheading; many semiconductor headings carry 0% base duty
Section 232 (Proclamation 11002)	25% on covered advanced computing chips
Section 301	Currently applies to certain Chinese-origin semiconductors under List 1–4A
Section 122 (Reciprocal tariffs)	Country-specific rates; may apply depending on origin
Chapter 99 additional	Various product-specific surcharges

A chip imported from a Section 301–covered country that also meets the Section 232 technical thresholds could face compounded duties. This is exactly the kind of multi-layer tariff scenario where manual calculation breaks down.

GingerControl is a trade compliance AI platform that helps importers, exporters, and customs brokers classify products, simulate tariff costs, and track policy changes. Its Tariff Calculator models all five tariff layers simultaneously — base duty, Section 232, Section 301, Chapter 99, and Section 122 — with date-sensitive calculations reflecting which rates apply on the actual entry date.

What Is the Market Impact of the Semiconductor Tariff?

Industry Scale

The global semiconductor market reached $791.7 billion in 2025 — a 25.6% increase year-over-year — and is projected to approach $1 trillion in 2026 according to the World Semiconductor Trade Statistics (WSTS). The United States imports approximately 80% of its semiconductor supply, with top sources including Taiwan ($14 billion), Malaysia ($12 billion), and Israel ($5 billion).

AI Infrastructure Cost Pressures

According to CSIS analysis, a 100% tariff on semiconductors could raise AI server costs by as much as 75%, with current and proposed policies threatening $75–100 billion in additional AI infrastructure costs over five years — equivalent to 15–20 fewer hyperscale data center facilities. Google, Amazon, Meta, and Microsoft collectively planned to spend over $350 billion on AI data centers in 2025 alone.

Supply Chain Responses

NVIDIA has raised prices on AI GPUs by 5–15%, with high-end AI accelerators seeing the steepest increases. Deloitte's 2026 semiconductor outlook notes that tariff uncertainty, combined with AI-driven demand surges, is creating pricing volatility across the entire supply chain — with memory prices projected to rise 30–50% through mid-2026.

What Happens Next: Phase 2 and the Negotiation Timeline

The Proclamation 11002 framework includes specific deadlines that importers should track:

Deadline	Action
April 14, 2026	Commerce Secretary and USTR must update the President on status/outcome of trade negotiations
July 1, 2026	Commerce Secretary must report on the market for semiconductors used in U.S. data centers; President may modify the tariff
TBD	Phase 2 broader tariffs on all semiconductors and derivative products, with tariff offset program

The Phase 2 tariff offset program is designed to reward companies investing in U.S. semiconductor manufacturing — a concept that parallels the CHIPS Act's 25% investment tax credit (Section 48D), which is set to expire for facilities where construction begins after December 31, 2026.

For compliance teams, the practical implication is clear: the current narrow tariff may expand significantly in the second half of 2026. Companies importing any semiconductor products — not just advanced AI chips — should be preparing classification and documentation systems now.

How GingerControl Helps

Correctly classifying semiconductor products under the HTS is the foundation of any tariff compliance strategy. GingerControl's HTS Classifier follows the same reasoning process a licensed customs broker uses — GRI analysis, Section/Chapter Note review, and cross ruling research — but at the speed and scale that semiconductor supply chains demand.

GingerControl is a pre-classification research tool. It produces audit-ready documentation that supports the classification decision; it does not provide legal advice or replace licensed customs expertise. For semiconductor imports, the Classifier can help determine whether a product falls under the covered HTS subheadings (8471.50, 8471.80, 8473.30) and generate the documentation needed to support an exemption claim.

FAQ

What is Section 232 and how does it apply to semiconductors?

Section 232 of the Trade Expansion Act of 1962 authorizes the President to adjust tariffs on imports that threaten U.S. national security. After a Commerce Department investigation concluded in December 2025 that semiconductor imports posed a national security threat, President Trump imposed a 25% tariff on a narrow category of advanced computing chips via Proclamation 11002, effective January 15, 2026.

Which specific chips are subject to the 25% semiconductor tariff?

The tariff covers logic integrated circuits classified under HTS subheadings 8471.50, 8471.80, or 8473.30 that meet specific Tensor Processing Performance (TPP) and DRAM bandwidth thresholds. The White House identified NVIDIA H200 and AMD MI325X as examples. Chips that do not meet the technical parameters — including most legacy and mid-range semiconductors — are not covered.

Are semiconductors imported for U.S. data centers exempt from the tariff?

Yes. Semiconductors imported for use in U.S. data centers above 100 MW are exempt under HTS 9903.79.03. Additional exemptions apply for chips used in R&D, by U.S. startups, for repairs, for public sector applications, and for non-data-center consumer and industrial uses. Importers must file under the correct HTS 9903 code and maintain end-use documentation.

How does the Section 232 semiconductor tariff stack with Section 301 duties?

The tariffs can compound. A covered chip imported from a country subject to Section 301 duties (e.g., China) may face both the 25% Section 232 tariff and the applicable Section 301 rate, in addition to any base MFN duty. GingerControl's Tariff Calculator models all tariff layers simultaneously to give importers a complete landed cost picture.

What documentation do importers need for a semiconductor tariff exemption?

CBP requires correct HTSUS sequencing, separate duty reporting for each tariff line, and end-use certification supporting the exemption claim. Importers should prepare purchase orders, installation plans, and end-use statements that demonstrate the chips will be used for an exempt purpose. Contact CBP's Trade Remedy Branch at TradeRemedy@cbp.dhs.gov for filing questions.

Will the semiconductor tariff expand beyond advanced AI chips?

The Commerce Department recommended Phase 2 tariffs covering broader semiconductor categories, including semiconductor manufacturing equipment and derivative products, at a "significant" rate. The President must receive a negotiations update by April 14, 2026, and a data center market report by July 1, 2026, before deciding on expansion. A tariff offset program for companies investing in U.S. manufacturing is expected to accompany any broader action.

How can importers classify semiconductor products for Section 232 compliance?

Semiconductor classification under the HTS requires analyzing whether a product meets the specific TPP and DRAM bandwidth thresholds defined in Proclamation 11002. GingerControl's HTS Classifier follows GRI logic and asks clarifying questions about product specifications before assigning a classification — producing audit-ready reports grounded in Section Notes, Chapter Notes, and relevant cross rulings. It is a pre-classification research tool that supports, rather than replaces, licensed customs expertise.

Navigating the Section 232 semiconductor tariff requires accurate HTS classification, end-use documentation, and real-time tariff calculations across multiple duty layers. GingerControl's Tariff Calculator models the full U.S. tariff stack — including Section 232, Section 301, Chapter 99, and Section 122 — so your team can see the complete duty picture before goods arrive at the port.
