Section 232 Semiconductor Tariffs 2026: What Importers Need to Know

As of January 15, 2026, a new 25% tariff applies to certain advanced semiconductors under Section 232 of the Trade Expansion Act. While the scope is narrow—targeting high-performance AI chips—the implications for importers, tech companies, and the broader semiconductor supply chain are significant.

Here's what you need to know.

Key Takeaways

25% additional duty on specific advanced logic semiconductors effective January 15, 2026
Narrow scope: Only chips meeting specific TPP and DRAM bandwidth parameters are covered
Named products: Nvidia H200 and AMD MI325X chips explicitly included
Use-based exemptions available for data centers, R&D, consumer products, and more
No drawback permitted for these tariffs
Broader tariffs may come: Negotiations ongoing; more expansive measures possible

What Are Section 232 Semiconductor Tariffs?

Presidential Proclamation 11002, issued January 14, 2026, imposed 25% ad valorem tariffs on a narrow set of advanced logic semiconductors. This action follows the Commerce Department's Section 232 investigation into the national security effects of semiconductor imports.

Unlike the broad IEEPA tariffs that apply country-wide, these Section 232 tariffs target specific products based on technical specifications—making HTS classification critical for determining duty liability.

Which Semiconductors Are Affected?

Covered HTS Subheadings

The tariffs apply to products classified under:

HTSUS Subheading	Description
8471.50	Processing units (not combined with input/output units)
8471.80	Other ADP units
8473.30	Parts and accessories for ADP machines

Technical Parameters

Not all products under these headings are covered. The tariff applies only to semiconductors (or products containing them) with:

Parameter Set A:

Total Processing Performance (TPP): 14,000 – 17,500
Total DRAM bandwidth: 4,500 – 5,000 GB/s

Parameter Set B:

Total Processing Performance (TPP): 20,800 – 21,100
Total DRAM bandwidth: 5,800 – 6,200 GB/s

What This Means in Practice

These technical thresholds describe high-performance AI/ML accelerator chips. The White House fact sheet explicitly names:

Nvidia H200 (and equivalent processors)
AMD MI325X

Consumer-grade graphics cards, standard processors, and most commercial semiconductors fall below these thresholds and are not covered.

Use-Based Exemptions

Even if your products meet the technical parameters, you may qualify for exemption based on end use. The Proclamation exempts covered semiconductors imported:

Exempt Uses

U.S. data centers — Chips used in domestic data center infrastructure
Repairs and replacements — Maintenance performed in the United States
Research and development — R&D activities involving subject semiconductors
Startups — Use by qualifying U.S. startup companies
Consumer applications — Non-data center uses including:
- Gaming
- Personal computing
- Professional visualization
- Workstation applications
- Automotive applications
Industrial applications — Non-data center civil uses including:
- Factory robotics
- Industrial machinery
Public sector — Government and public agency applications
Supply chain strengthening — Other uses the Secretary determines contribute to domestic manufacturing capacity

Claiming Exemptions

CBP has not yet released detailed guidance on documenting exemption eligibility. However, based on precedent with other use-based tariff exclusions, importers should:

Maintain end-use documentation showing the ultimate application
Prepare end-use certificates if requested
Keep detailed records of customer contracts, installation sites, and product destinations
Work with customs brokers to ensure proper entry coding

How These Tariffs Interact with Other Duties

What's Stacked

Products subject to the 25% Section 232 semiconductor tariff remain liable for:

MFN (Most Favored Nation) duties — Base tariff rates
Section 301 tariffs — If Chinese-origin
Antidumping/Countervailing duties — If applicable to the product

What's Excluded

Products paying the 25% Section 232 semiconductor tariff are excluded from:

Other Section 232 tariffs (steel, aluminum, etc.)
IEEPA reciprocal tariffs
IEEPA border security tariffs

No Duty Drawback

The Proclamation explicitly states: "No drawback shall be available" for the additional 25% tariff.

This means if you export products containing these chips, you cannot recover the Section 232 duty—unlike standard MFN duties which may qualify for drawback.

Classification Matters: How to Determine Liability

Determining whether your products are subject to these tariffs requires:

Step 1: Verify HTS Classification

Is your product classified under 8471.50, 8471.80, or 8473.30? If not, the Section 232 semiconductor tariff doesn't apply.

Step 2: Check Technical Specifications

Does the semiconductor (or semiconductor content) meet the TPP and DRAM bandwidth thresholds?

Metric	Threshold A	Threshold B
TPP	14,000 – 17,500	20,800 – 21,100
DRAM Bandwidth	4,500 – 5,000 GB/s	5,800 – 6,200 GB/s

If specs fall outside both ranges, the tariff doesn't apply.

Step 3: Evaluate End Use

If your product meets the technical parameters, does the end use qualify for exemption?

This three-step analysis should be documented for every covered import.

Why This Matters Beyond AI Chips

While the current tariffs are narrow, the Section 232 investigation covered all semiconductors, manufacturing equipment, and derivative products. The Commerce Secretary found that imports in all three categories threaten U.S. national security.

What's Not (Yet) Covered

The Proclamation imposes no immediate tariffs on:

Standard semiconductors (below TPP/DRAM thresholds)
Semiconductor manufacturing equipment
Legacy chips and consumer electronics
Memory chips (standard DRAM, NAND flash)

But Broader Tariffs May Come

The Proclamation directs the Commerce Secretary and USTR to negotiate with foreign jurisdictions on arrangements to strengthen the U.S. semiconductor industry. If these negotiations fail, broader tariffs could follow—mirroring how automobile tariffs evolved from the first Trump administration.

Implication: Companies importing semiconductors or semiconductor equipment should monitor developments closely. Current exemptions could narrow, and additional product categories could become subject to Section 232 tariffs.

The Bottom Line

The Section 232 semiconductor tariffs mark the beginning—not the end—of trade policy action in this sector. While current coverage is narrow (specific AI chips meeting technical thresholds), the administration has clearly signaled that broader measures are on the table.

For importers:

Verify your exposure — Check whether your products meet the technical parameters
Document exemptions — If you qualify for use-based exclusions, prepare supporting evidence
Plan for expansion — The tariff landscape for semiconductors is likely to evolve

Don't wait for broader tariffs to assess your classification accuracy. The time to get your HTS codes right is now.

Frequently Asked Questions

Are all Nvidia and AMD chips subject to the 25% tariff?

No. Only chips meeting the specific TPP and DRAM bandwidth parameters are covered. Consumer GPUs like the RTX 4090 or standard Ryzen processors fall below these thresholds. The tariff specifically targets high-performance AI accelerators like the H200 and MI325X.

How do I know if my chip meets the technical thresholds?

Check the manufacturer's specifications for Total Processing Performance (TPP) and DRAM bandwidth. If these aren't listed, contact your supplier for technical data sheets that document these metrics.

Can I get a tariff exemption by claiming data center use?

Yes, if the semiconductors are imported for use in U.S. data center infrastructure. You'll need documentation supporting this end use. CBP guidance on specific documentation requirements is expected.

What if my product contains a covered chip but has other components?

If the entire product is classified under 8471.50, 8471.80, or 8473.30, and it contains a semiconductor meeting the technical thresholds, the tariff would apply—unless an end-use exemption applies.

Will semiconductor tariffs expand?

The Proclamation directs ongoing negotiations, suggesting broader tariffs are possible if diplomatic efforts to strengthen U.S. semiconductor capacity don't succeed. The Commerce Department's investigation found national security threats from all semiconductor imports, not just advanced AI chips.
