Semiconductors sit at the intersection of trade policy, national security, and industrial strategy. IEEPA surcharges on chip imports added significant cost pressure to an already strained global supply chain during 2025-2026. The Supreme Court’s ruling creates a recovery opportunity for companies that import semiconductors, integrated circuits, and related components from covered countries.
The semiconductor sector presents unique recovery considerations — high unit values, complex supply chains spanning multiple countries, and the interaction between trade remedies and industrial policy (including CHIPS Act incentives). This guide walks through what semiconductor importers need to know. For the general recovery framework, see the complete guide to IEEPA tariff refunds.
Which semiconductor products qualify
IEEPA surcharges applied to semiconductor products imported from covered countries during the tariff period. The most commonly affected product categories include:
Integrated circuits (ICs). Processors, memory chips (DRAM, NAND flash), microcontrollers, FPGAs, ASICs, and analog/mixed-signal devices. These are typically classified under HTS Chapter 85 (8541, 8542).
Discrete semiconductors. Diodes, transistors, thyristors, and power semiconductors. Often imported as individual components for board assembly.
Semiconductor wafers. Silicon wafers (finished and unfinished), GaAs wafers, SiC wafers, and other substrate materials. These are inputs to domestic chip fabrication.
Semiconductor manufacturing equipment. Lithography systems, deposition equipment, etching tools, testing and inspection equipment, and cleanroom components. While some equipment is exempt from certain tariffs, IEEPA surcharges often applied regardless.
Packaging and test components. Lead frames, substrates, bonding wire, and test sockets. The back-end semiconductor supply chain is heavily concentrated in Asia.
Passive components. While not semiconductors per se, capacitors, resistors, and inductors imported from covered countries alongside active components were subject to IEEPA surcharges and are similarly recoverable.
| Product | Typical HTS | Key Origins (Covered) |
|---|---|---|
| ICs / Processors | 8542 | China, Taiwan, South Korea |
| Memory (DRAM/NAND) | 8542 | China, South Korea |
| Discrete devices | 8541 | China, Taiwan |
| Wafers | 3818, 8541 | China, Japan |
| Equipment | 8486, 9031 | China, Japan |
| Passive components | 8532, 8533 | China, Japan, Taiwan |
Country-of-origin complexity in semiconductors
Semiconductors have arguably the most complex country-of-origin stories in global trade. A chip might be:
- Designed in the U.S.
- Fabricated on a wafer in Taiwan
- Packaged and tested in China
- Shipped to the U.S. as a finished IC
The country of origin for customs purposes depends on where “substantial transformation” occurred. For most semiconductors, the country where the wafer was fabricated (front-end processing) is typically the country of origin, not the country where the chip was packaged (back-end processing).
This matters for IEEPA recovery because the IEEPA surcharge depended on country of origin. If a chip was fabricated in Taiwan but packaged in China, and the entry listed China as the country of origin, the chip may have been assessed a higher IEEPA rate than it should have been. Conversely, if a chip fabricated in China was assembled in a non-covered country, it may still have the Chinese origin for duty purposes.
Review the country-of-origin determinations on your semiconductor entries carefully. Errors in origin classification could mean:
- You paid IEEPA surcharges on chips that should have been exempt (additional recovery beyond the standard IEEPA refund)
- You didn’t pay IEEPA surcharges on chips that should have been assessed (potential liability, though unlikely to be pursued in the current environment)
Your trade compliance team should review these determinations as part of the recovery process.
The IEEPA-CHIPS Act interaction
Companies receiving CHIPS Act incentives for domestic semiconductor manufacturing should evaluate the interaction between IEEPA recovery and their CHIPS Act agreements:
CHIPS Act funding agreements may include provisions about import practices, supply chain sourcing, and cost structures. If your CHIPS Act proposal or agreement referenced IEEPA tariff costs as part of the economic justification for domestic investment, the recovery of those tariff costs could theoretically affect the analysis.
In practice, the IEEPA recovery is unlikely to affect CHIPS Act funding directly — the funding is tied to domestic capital investment commitments, not to import cost structures. But companies should consult with counsel to confirm that the recovery doesn’t trigger any notification or adjustment provisions in their CHIPS Act agreements.
Forward-looking implications. The elimination of IEEPA tariffs on semiconductor imports changes the cost equation for companies deciding between domestic fabrication (supported by CHIPS Act incentives) and continued importing. The recovery reduces the retroactive cost of importing, but the strategic case for domestic manufacturing extends beyond tariff avoidance.

Calculating semiconductor IEEPA recovery
Semiconductor imports tend to be high-value, low-volume compared to bulk commodities. The IEEPA surcharge on a single shipment of advanced ICs could be hundreds of thousands or millions of dollars.
Sample calculation
| Component | Annual Import Value | IEEPA Rate | Annual IEEPA Duty |
|---|---|---|---|
| ICs from China | $15,000,000 | 145% | $21,750,000 |
| Memory from South Korea | $8,000,000 | 25% | $2,000,000 |
| Wafers from Japan | $5,000,000 | 24% | $1,200,000 |
| Equipment from China | $3,000,000 | 145% | $4,350,000 |
| Total | $31,000,000 | $29,300,000 |
For companies with China-origin semiconductor imports, the IEEPA surcharge at 145% means the duty exceeded the product value. The recovery on these entries is transformative.
Statutory interest amplification
Given the high dollar values per entry, statutory interest under 19 U.S.C. Section 1505 compounds to significant amounts. On a single entry with $500,000 in IEEPA duties, at 3% annual interest over 24 months, the interest component alone is approximately $30,000.
Industry-specific recovery considerations
Just-in-time supply chain impact
Semiconductor supply chains operate on tight schedules. During the IEEPA period, the tariff cost often forced importers to accelerate or delay shipments, build buffer inventory, or redirect supply chains. The recovery doesn’t compensate for these operational disruptions, but it does return the direct financial cost. For companies that shifted to alternative suppliers or routes to mitigate IEEPA exposure, the recovery changes the retroactive cost-benefit analysis.
Bonded warehouse and FTZ strategies
Some semiconductor importers used bonded warehouses or Foreign Trade Zones to defer duty payments during the IEEPA period. Entries admitted to an FTZ under privileged foreign status may have been assessed IEEPA duties; entries under zone-restricted status may have had different treatment. Review your FTZ entries separately.
Consignment and vendor-managed inventory
Semiconductor supply chains often use consignment models where the supplier retains ownership until the product is consumed. The importer of record on the customs entry — not the owner of the goods — holds the recovery right. If your supplier was the IOR on consignment shipments, the recovery belongs to them unless your agreement provides otherwise.
Export controls and re-export considerations
Some semiconductor products subject to IEEPA tariffs are also subject to export control regulations (EAR/ITAR). The IEEPA recovery process is entirely separate from export controls — filing for a tariff refund doesn’t affect your export compliance obligations or your products’ controlled status.
Recovery paths for semiconductor importers
The four recovery paths apply, with some path-specific considerations for the semiconductor sector:
PSCs for unliquidated entries are the fastest route. High-value semiconductor entries are worth filing immediately. Work with your broker to prioritize the largest-dollar entries.
Protests for liquidated entries within the 180-day window. Given the high per-entry values in semiconductors, even a small number of missed deadlines can mean millions in lost recovery.
CIT litigation is almost always justified for semiconductor entries given the high duty amounts. Even a single entry with $100,000+ in IEEPA duties makes the legal cost of CIT action worthwhile.
Immediate capital through claim assignment may be attractive for semiconductor companies with large claims and near-term capital needs — product development cycles, capacity expansion, or working capital requirements. The treasury modeling guide covers the NPV analysis.
Forward-looking considerations
Trade policy uncertainty
Semiconductors remain at the center of U.S.-China trade tensions. While IEEPA tariffs have been struck down, other trade restrictions on semiconductor technology continue to evolve. Future tariffs under different legal authorities remain possible.
Inventory and supply chain planning
With IEEPA tariffs eliminated and refunds in process, semiconductor importers should reassess their inventory strategies. Safety stock built to hedge against tariff uncertainty may no longer be necessary at current levels. Working capital tied up in excess inventory can be released.
Supplier negotiations
Chinese semiconductor suppliers and intermediaries who reduced prices during the IEEPA period may expect pricing conversations now that the tariff is gone. Review your supplier agreements for any tariff-related concessions that may need adjustment.
The design house and fabless company perspective
Many semiconductor companies don’t manufacture their own chips — they’re “fabless” design houses that contract with foundries for fabrication and with OSATs (outsourced semiconductor assembly and test) for packaging. Their IEEPA exposure depends on who is the importer of record:
If the fabless company is the IOR: You import finished chips from the foundry or OSAT, and you paid the IEEPA surcharge. The recovery is yours.
If the foundry or OSAT ships directly to your customer: The IOR may be the end customer, not you. You may not have a direct IEEPA claim, but your customer’s landed cost was affected, which may have indirectly affected your pricing or demand.
If a distributor is the IOR: Many semiconductors are sold through authorized distributors (Arrow, Avnet, Mouser, etc.) who handle the import. The IEEPA recovery right belongs to the distributor. If the distributor passed IEEPA tariff costs through in component pricing, the recovery may flow back to you as a price adjustment. Review your distribution agreements.
Test and assembly operations
Semiconductor back-end operations (packaging, test, burn-in) are concentrated in Southeast Asia — Malaysia, Vietnam, Thailand, and the Philippines. Chips fabricated in Taiwan or South Korea are often packaged in these countries before being shipped to the U.S. The country of origin for customs purposes may be the packaging country, which could have a different IEEPA rate than the fabrication country.
This means two otherwise identical chips — same die, same specification — could have different IEEPA rates based on where they were packaged. If your supply chain routes the same chip through different packaging locations, verify the origin and IEEPA rate on each entry.
Automotive semiconductor implications
The automotive semiconductor supply chain was already strained by the chip shortage of 2021-2023. IEEPA surcharges added cost pressure to an already-stressed supply chain. Automotive OEMs and Tier 1 suppliers who import semiconductors for vehicle production may have significant IEEPA claims.
Automotive-qualified chips often have limited sourcing options — you can’t simply switch suppliers when a chip has been qualified through a multi-year automotive validation process. This means automotive importers had to absorb the IEEPA surcharge with no ability to shift to alternative sources. The recovery is particularly important for this segment.
Pass-through in automotive. Automotive supply chains have well-established cost-sharing mechanisms. If you passed IEEPA tariff costs through to your OEM customer via price adjustments or surcharges, the recovery may trigger a reverse adjustment. Automotive procurement teams track these costs carefully and will expect a conversation.
Geopolitical context and future risk
Semiconductors are at the center of U.S.-China strategic competition. The IEEPA ruling removed one tariff layer, but the broader technology competition continues:
Export controls on advanced chips. The U.S. maintains export controls on advanced semiconductor technology to China. These controls restrict the sale of cutting-edge chips and manufacturing equipment. The IEEPA recovery doesn’t change export control policy.
Entity List restrictions. Chinese semiconductor companies on the Entity List face additional trade restrictions. If you import products from or through entities on the Entity List, the compliance implications are separate from IEEPA recovery.
Future tariff risk under other authorities. Congress could authorize new tariffs on semiconductor products under different legal authorities. The IEEPA precedent — that emergency powers can’t be used for tariffs — narrows the available tools but doesn’t eliminate them.
Supply chain resilience investment. The recovered IEEPA capital can fund supply chain diversification — qualifying alternative foundries, building strategic inventory, or investing in domestic packaging and test capacity.
Getting started
- Pull entry data from the ACE portal for all semiconductor entries during the IEEPA period.
- Verify country-of-origin determinations on each entry — this is especially important for semiconductors given the multi-country supply chain.
- Separate IEEPA from Section 301. Chinese semiconductor products are often subject to both. Only IEEPA is recoverable.
- Prioritize by dollar value. File the highest-value entries first.
- Request an Impact Assessment for a complete analysis of your semiconductor import IEEPA exposure.
Data center and AI hardware implications
The explosive growth of AI workloads has driven unprecedented demand for GPU accelerators, HBM (high-bandwidth memory), networking ASICs, and custom AI chips. Many of these components are manufactured in covered countries:
GPU and accelerator imports. Advanced AI accelerators manufactured in Taiwan and packaged in Asia. These are among the highest-value per-unit semiconductor imports, with individual chips costing thousands of dollars.
HBM stacking and packaging. High-bandwidth memory stacks from South Korea (Samsung, SK Hynix). The IEEPA surcharge on a single shipment of HBM can be hundreds of thousands of dollars.
Networking silicon. Custom ASICs and switches for data center networking, often designed in the U.S. but manufactured and packaged in Asia.
Server and infrastructure components. Power supplies, cooling systems, and rack components that include semiconductor content from covered countries.
Data center operators and cloud providers importing hardware during the IEEPA period may have substantial recovery claims. Given the scale of AI infrastructure investment, even a single large hardware order can generate millions in recoverable IEEPA surcharges.
The electronics manufacturing services (EMS) model
Many semiconductor-consuming products are manufactured by EMS providers (Foxconn, Jabil, Flex, etc.) who may handle the import of semiconductor components on behalf of brand owners. In these arrangements:
If the EMS is the IOR, the recovery right belongs to the EMS provider. Brand owners should review their EMS contracts for provisions about tariff costs and refund allocation.
If the brand owner is the IOR, the recovery right belongs to the brand. This is common when the brand directly procures semiconductors and ships them to the EMS for assembly (consignment or vendor-managed inventory models).
Hybrid models where some components are procured by the brand and others by the EMS require entry-level analysis to determine which entities hold which recovery rights.
Semiconductor importers often have some of the largest per-entry IEEPA claims in any industry. The recovery opportunity is significant — but so is the complexity. Get the analysis right, and the return is worth every hour invested.
