California is the epicenter of American imports. If you’re reading this, you probably already know that — because you’ve been paying IEEPA tariffs on goods flowing through the busiest port complex in the Western Hemisphere. The Supreme Court’s February 2026 ruling in Learning Resources, Inc. v. Trump invalidated those tariffs, and now California importers are sitting on what may be the single largest concentration of refundable duties in the country.
We’re talking about an estimated $48 billion in IEEPA tariff exposure flowing through California ports between February 2025 and February 2026. That’s not a typo. California handles roughly 40% of all U.S. containerized imports, and every one of those shipments from a targeted country carried an IEEPA surcharge that’s now been ruled unconstitutional.
Here’s what California importers need to know about getting that money back.
Why California’s IEEPA Exposure Is Uniquely Massive
California’s dominance in U.S. trade isn’t just about volume — it’s about the specific trade lanes that got hit hardest by IEEPA tariffs. The Port of Los Angeles and Port of Long Beach together form the San Pedro Bay port complex, which handles more Chinese imports than any other gateway in the country. And China was the primary target of IEEPA tariff actions.
Top import industries flowing through California ports:
| Industry | Estimated Annual Value | Primary HTS Categories | IEEPA Rate Applied |
|---|---|---|---|
| Consumer Electronics | $82 billion | HTS 8471, 8517, 8528 | 20-34% |
| Furniture & Home Goods | $28 billion | HTS 9401, 9403, 9404 | 20-34% |
| Apparel & Textiles | $24 billion | HTS 6109, 6110, 6204 | 20-34% |
| Auto Parts | $18 billion | HTS 8708, 8407, 8409 | 20-25% |
| Toys & Games | $14 billion | HTS 9503, 9504, 9505 | 20-34% |
| Industrial Machinery | $12 billion | HTS 8479, 8481, 8483 | 20-25% |
The HTS categories under 9903.01 and 9903.02 that carried IEEPA surcharges are disproportionately represented in California’s import mix. Consumer electronics alone — smartphones, laptops, monitors, peripherals — account for a staggering share of trans-Pacific volume.
The China Factor
Here’s the number that matters: approximately 65% of all Chinese goods entering the United States come through California ports. When the IEEPA tariffs imposed rates of 20-34% on Chinese-origin merchandise, California importers bore the brunt. If you import Chinese-manufactured goods through LA or Long Beach, your per-container IEEPA exposure likely ranged from $8,000 to $45,000 depending on commodity type and declared value.
That’s per container. If you moved 50 containers over the tariff period, you’re potentially looking at $400,000 to $2.25 million in recoverable duties. For larger importers moving hundreds or thousands of containers, the numbers scale dramatically. Check your eligibility and estimated refund amount to understand where you stand.
Oakland and Northern California
Don’t overlook the Port of Oakland. While it handles roughly one-tenth the volume of San Pedro Bay, Oakland is a critical gateway for agricultural imports, wine, specialty foods, and tech components flowing into the Bay Area and Silicon Valley supply chains. Oakland importers tend to have smaller individual shipment values but high frequency, which means the cumulative IEEPA exposure adds up fast.
Oakland also handles significant volumes from Vietnam, Taiwan, and South Korea — all countries that were subject to various IEEPA tariff actions. If you’ve been importing components through Oakland for assembly or distribution, those duties are refundable.
California’s Key Ports of Entry
Understanding which port district processed your entries matters because it affects your CBP relationship and potentially your refund processing timeline.
Port of Los Angeles (District 2704)
The busiest container port in the Western Hemisphere. In 2025, LA processed over 4.8 million TEUs (twenty-foot equivalent units). The port’s import mix skews heavily toward Chinese consumer goods, which means IEEPA exposure per TEU is among the highest in the nation.
Key considerations for LA importers:
- CBP’s LA field office is processing a massive backlog of post-summary corrections
- Entries filed through LA brokers may have different liquidation timelines than other ports
- The 180-day protest window for early-period entries is already ticking
Port of Long Beach (District 2704)
Long Beach handles slightly different commodity mixes than LA — more auto parts, industrial equipment, and petroleum products. But the IEEPA exposure is just as significant. Long Beach has been the primary discharge port for several major shipping alliances’ Asia services, meaning your goods may have entered through Long Beach even if your broker is based elsewhere in California.
Port of Oakland (District 2809)
Oakland’s commodity profile includes more agricultural products, beverages, and specialty goods. IEEPA rates on these categories varied, but many fell under the 20% China surcharge. Oakland importers should pay particular attention to entries involving country-specific tariff rates since Oakland sees more diverse origin countries than the southern California ports.
Inland Ports and FTZs
California has several Foreign Trade Zones that processed IEEPA-dutiable goods, including FTZ 202 (Los Angeles), FTZ 50 (Long Beach), and FTZ 18 (San Jose). If you used an FTZ to defer or reduce duties, the IEEPA component is still refundable — but the documentation requirements are slightly different. Your impact assessment should account for FTZ entries separately.
Which Recovery Path Works Best for California Importers
The four recovery paths apply everywhere, but California importers face some unique considerations that affect which path makes the most sense.
Post-Summary Corrections for Recent Entries
If you imported through California ports in the second half of 2025 or early 2026, many of your entries are likely still unliquidated. CBP’s average liquidation timeline is approximately 314 days from entry filing, which means entries from June 2025 onward may still be open for post-summary corrections.
This is the fastest path. Your customs broker files the correction through ACE, CBP recalculates without the IEEPA surcharge, and you get your money back in days to weeks. No lawyers, no waiting. For a step-by-step walkthrough, see 7 steps to file your IEEPA tariff refund.
Protests for Liquidated Entries
For entries that have already liquidated — generally those from February through May 2025 — you’ll need to file a formal CBP protest under 19 U.S.C. § 1514. The 180-day protest window runs from the date of liquidation, not the date of entry. Given the volume of California entries, some early-period liquidations may be approaching their protest deadlines.
This is urgent. If you imported through California ports in February or March 2025, check your liquidation dates immediately. Missing the 180-day window pushes you to the more expensive and time-consuming CIT litigation path.
CIT Litigation for Expired Entries
Some California importers will have entries where the protest window has already closed. The Court of International Trade remains an option, but it requires a trade attorney admitted to the CIT bar. Given the volume of potential claims in California, CIT filings from the state could be substantial.
Immediate Capital Through Claim Assignment
California importers with large portfolios and cash-flow needs have another option: assigning claims for immediate capital. Instead of waiting 18-36 months for government processing, you receive a lump-sum payment now — typically 70-85 cents on the dollar — in exchange for assigning your refund rights. For importers carrying significant working capital strain from a year of IEEPA surcharges, this can be the right move.

Specific Considerations for California Importers
Volume-Based Processing Challenges
California’s sheer import volume means CBP’s local offices are going to be swamped with refund claims. The LA/Long Beach CBP district processes more entry summaries than any other in the country. When hundreds of thousands of post-summary corrections and protests arrive simultaneously, processing times will likely stretch beyond the national average.
What this means for you: File early. The importers who get their paperwork in first will be at the front of the queue. Waiting costs money — not just in terms of delayed refunds, but in potential complications if entries liquidate while you’re still gathering documentation. Read more about the cost of waiting to file your claim.
California’s Trade Broker Ecosystem
California has the densest concentration of licensed customs brokers in the country. That’s generally good news — competition keeps fees reasonable and expertise high. But it also means broker firms are going to be stretched thin handling IEEPA recovery work for their entire client base simultaneously.
If your broker hasn’t already contacted you about IEEPA recovery options, reach out proactively. Some California brokers are prioritizing larger clients, which means smaller importers may need to be assertive about getting their claims filed. Understand the difference between what a trade attorney does versus a claims advisory firm to make sure you’re getting the right help.
Multi-Port Importers
Many California-based importers use multiple ports. You might bring containers through LA/Long Beach, receive air cargo through LAX, and occasionally route shipments through Oakland or even out-of-state ports. Each port district may have processed your entries on different timelines, which means you could have a mix of unliquidated entries (eligible for PSC), recently liquidated entries (eligible for protest), and older liquidated entries (requiring CIT action).
This is exactly why an impact assessment is critical. You need a port-by-port, entry-by-entry analysis to determine which recovery path applies to each shipment.
Agricultural and Perishable Goods Importers
California is the nation’s largest agricultural import gateway. Fresh produce, nuts, seafood, and specialty foods from China, Mexico, and other targeted countries carried IEEPA surcharges. These importers often operate on razor-thin margins, which means the IEEPA tariffs hit particularly hard — and the refunds will be particularly welcome.
If you import perishable goods, your entries tend to liquidate faster than durable goods because CBP prioritizes clearance speed. That means more of your entries may already be liquidated, pushing you toward the protest path rather than PSCs.
How to Calculate Your California IEEPA Refund
Your refund amount equals the total IEEPA surcharges paid across all qualifying entries. Here’s how to estimate it:
- Pull your ES-003 report from ACE for all entries between February 4, 2025, and February 24, 2026
- Identify entries with HTS codes under headings 9903.01.__ and 9903.02.__ — these are the IEEPA-specific tariff lines
- Sum the duties paid under those tariff lines across all entries
- Categorize by liquidation status — unliquidated entries go the PSC route, liquidated entries go the protest route

Rough benchmarks for California importers by size:
| Importer Size | Annual Import Value | Estimated IEEPA Paid | Likely Recovery |
|---|---|---|---|
| Small (1-10 containers/month) | $2M-$20M | $150K-$1.5M | $140K-$1.4M |
| Mid-size (10-50 containers/month) | $20M-$100M | $1.5M-$8M | $1.4M-$7.5M |
| Large (50+ containers/month) | $100M+ | $8M+ | $7.5M+ |
These are rough estimates. Actual amounts depend on commodity type, country of origin, and the specific IEEPA rates that applied to your goods.
Frequently Asked Questions for California Importers
Do I need a California-based broker or attorney to file my IEEPA claim?
No. Your claim is filed with CBP through the ACE system, and any licensed customs broker can handle it regardless of location. However, working with a broker who has direct relationships with the LA/Long Beach or Oakland CBP offices can sometimes expedite processing. If you’re pursuing CIT litigation, your attorney must be admitted to the CIT bar in New York, not California state bar — though many California-based trade attorneys hold CIT admission.
My goods came through LA but I’m headquartered in another state. Where do I file?
Your claim is tied to the port of entry and the entry summary, not your business location. If your goods entered through the Port of Los Angeles (District 2704), the post-summary correction or protest is filed with that CBP district. Your customs broker typically handles this filing based on where the original entry was processed.
I use a freight forwarder, not a customs broker. Can they handle my IEEPA refund?
Freight forwarders are not licensed to file customs entries, protests, or post-summary corrections. They may partner with a customs broker who can handle the filing, but you should confirm this directly. If your forwarder used a sub-contracted broker for your entries, that broker is the one who needs to file your refund claim. Don’t assume your forwarder is handling it — ask specifically about IEEPA recovery and get confirmation in writing.
California FTZ and Bonded Warehouse Entries
California’s Foreign Trade Zone program is among the most active in the country. FTZ 202 (Los Angeles), FTZ 50 (Long Beach), FTZ 18 (San Jose), and FTZ 143 (West Sacramento) all processed IEEPA-dutiable goods during the tariff period. If you withdrew goods from an FTZ for consumption and paid IEEPA surcharges, those duties are refundable through the same recovery paths.
Bonded warehouse entries follow the same logic: if goods were withdrawn for consumption during the IEEPA period and assessed surcharges, the refund applies. California’s extensive network of bonded facilities near the ports means many importers used these programs — make sure your recovery claim captures FTZ and bonded entries alongside your direct-entry filings.
The Time Value of Your Refund
Every day your IEEPA refund sits with the government is a day that capital isn’t working in your business. For California importers with multi-million-dollar refund claims, the time value of money is a real consideration. At a 5% annual cost of capital, a $5 million refund delayed by 24 months costs you $500,000 in opportunity cost.
This is why the cost of waiting matters. Filing today versus filing six months from now could mean the difference between recovering your capital in 2027 versus 2028. And for entries approaching the 180-day protest window, waiting isn’t just expensive — it could mean losing the right to recover altogether.
What to Do Right Now
If you’re a California importer, here’s your action plan:
- Pull your ACE data. Request your ES-003 report covering February 4, 2025, through February 24, 2026. This is the foundation of your entire claim.
- Check liquidation dates. For entries that have already liquidated, calculate whether you’re still within the 180-day protest window. If any are close to expiring, file protective protests immediately.
- Talk to your broker. Confirm they’re prepared to handle IEEPA post-summary corrections and protests. If they’re overwhelmed, consider engaging a specialized claims advisory firm.
- Get an impact assessment. A professional impact assessment maps every entry, identifies the optimal recovery path for each, and gives you a clear dollar figure for your total refundable amount.
California importers collectively paid more IEEPA tariffs than importers in any other state. The refund pool is massive, but it won’t collect itself. The protest deadlines are real, the processing queue is going to be long, and the importers who move first will recover first.
