The Mid-Atlantic corridor from Baltimore to Newark is the densest concentration of import infrastructure on the East Coast. New Jersey alone is home to more warehouses, distribution centers, and customs brokers per square mile than almost anywhere else in the country — and every importer in this region has been paying IEEPA tariffs that are now unconstitutional.
Estimated IEEPA exposure for Mid-Atlantic importers: $22-28 billion during the tariff period. This region’s proximity to the Port of New York/New Jersey, the Port of Philadelphia, and the Port of Baltimore creates a multi-port import ecosystem where goods flow continuously from ship to warehouse to consumer.
The Supreme Court’s ruling means all those surcharges are coming back. But Mid-Atlantic importers need a coordinated strategy across multiple port districts to capture every refundable dollar.
The Mid-Atlantic Import Corridor
The Mid-Atlantic is unique because it functions as a single economic zone for import purposes, even though it spans multiple states and CBP port districts. An importer headquartered in Edison, New Jersey, might receive containers through Port Newark, air cargo through Newark Liberty International, breakbulk through Philadelphia, and auto parts through Baltimore — all within a two-hour drive.
Top import industries in the Mid-Atlantic:
| Industry | Annual Import Value | Primary HTS Categories | IEEPA Rate |
|---|---|---|---|
| Consumer Electronics | $22 billion | HTS 8471, 8517, 8528 | 20-34% |
| Pharmaceuticals & APIs | $18 billion | HTS 2933, 2934, 3004 | 20-25% |
| Apparel & Textiles | $16 billion | HTS 6109, 6110, 6204 | 20-34% |
| Chemicals & Plastics | $12 billion | HTS 2901-2942, 3901-3926 | 20-25% |
| Food & Beverages | $10 billion | HTS Chapters 2-22 | 20-25% |
| Auto Parts & Vehicles | $8 billion | HTS 8708, 8703 | 20-25% |
New Jersey: The Warehouse State
New Jersey’s role in American commerce goes far beyond its ports. The state hosts over 1 billion square feet of warehouse and distribution space, making it the logistics backbone of the Northeast. Companies based in New Jersey import goods for distribution across the Eastern Seaboard, which means NJ-based importers often account for a disproportionate share of IEEPA duties paid at regional ports.
If you operate a New Jersey-based distribution business, your IEEPA exposure likely includes entries across multiple port districts. Your goods may enter through Newark (District 4601), Philadelphia (District 1101), or even Baltimore (District 1303) — and each port’s entries need to be captured for your refund claim.
The Pharmaceutical Corridor
The Mid-Atlantic region, particularly New Jersey, is the center of the U.S. pharmaceutical industry. Major pharma companies headquartered in NJ import active pharmaceutical ingredients (APIs) and finished products from China and India — both IEEPA-targeted origins. The surcharges on pharmaceutical imports were particularly painful because these are essential goods that couldn’t be easily sourced elsewhere.
Pharmaceutical importers often deal with complex HTS classifications that span multiple tariff lines per entry. Your refund claim needs to isolate the IEEPA component on each line. This is more complex than a standard consumer goods claim but potentially very high-value. Check the complete guide to IEEPA tariff refunds for details on multi-line entry processing.
Key Mid-Atlantic Ports of Entry
Port Newark / Elizabeth (District 4601)
The Port of New York and New Jersey is the region’s dominant maritime gateway, handling over 9.1 million TEUs annually. Port Newark and the Elizabeth Marine Terminal are the primary container facilities, processing a staggering diversity of goods from virtually every IEEPA-targeted country.
IEEPA considerations for Newark importers:
- Highest container volume on the East Coast means long processing queues for refund claims
- Diverse commodity mix means complex multi-line entries are common
- CBP District 4601 also covers JFK and Newark Liberty air cargo
Philadelphia / Camden (District 1101)
The PhilaPort complex handles approximately 700,000 TEUs plus significant breakbulk, refrigerated, and bulk cargo. Philadelphia is a critical gateway for perishable imports, steel, and specialty industrial goods.
Key considerations:
- Refrigerated cargo (including food imports from IEEPA-targeted countries) is a specialty
- Steel and metal imports may have both Section 232 and IEEPA duty components — only the IEEPA portion is refundable through this process
- Separate CBP district from Newark, requiring separate filings
Port of Baltimore (District 1303)
Baltimore is one of the nation’s largest vehicle import ports and handles significant volumes of farm equipment, construction machinery, and roll-on/roll-off cargo. If you import vehicles or heavy equipment through Baltimore, the per-unit IEEPA surcharge was substantial.
Key considerations:
- Vehicles from IEEPA-targeted countries carried surcharges worth thousands per unit
- Heavy machinery and equipment imports have high declared values and correspondingly high IEEPA duty amounts
- The Dundalk Marine Terminal and Seagirt Marine Terminal process the bulk of containerized cargo
Wilmington, Delaware (District 1101)
The Port of Wilmington handles fresh fruit and juice concentrate — particularly from Latin American origins — plus containerized cargo. While smaller than Philadelphia, Wilmington’s specialty in perishable imports means IEEPA surcharges on food products flowing through this port are significant.
Air Cargo: Newark Liberty and Philadelphia International
Both airports handle substantial international air cargo. Newark Liberty Airport’s air cargo facilities (under District 4601) process high-value electronics, pharmaceuticals, and express shipments from IEEPA-targeted countries. Philadelphia’s air cargo operation is smaller but growing.
Recovery Paths for Mid-Atlantic Importers
Multi-District Filing Strategy
The Mid-Atlantic’s biggest challenge for IEEPA recovery is the multi-district nature of the port system. Your entries may span Districts 4601 (Newark/JFK), 1101 (Philadelphia/Wilmington), and 1303 (Baltimore). Each district processes claims independently, and processing times will vary.
The four recovery paths apply uniformly, but your strategy needs to account for:
- Different liquidation timelines at different ports
- Different processing speeds for post-summary corrections
- Potential coordination issues if you use different brokers for different ports
Prioritize by Protest Deadline
With entries across multiple ports, your 180-day protest window deadlines will vary. An entry that liquidated at Port Newark in November 2025 has a different protest deadline than one that liquidated at Baltimore in December 2025. Map every liquidated entry by its protest deadline and work backward from the earliest expiration.
This is exactly the kind of analysis that an impact assessment delivers. You get a complete timeline of every entry, its liquidation status, its protest deadline (if applicable), and the recommended recovery path.
The PSC Opportunity for Recent Entries
If you imported through Mid-Atlantic ports in the second half of 2025 or early 2026, many of those entries are likely still unliquidated. Post-summary corrections are the fastest recovery path — your broker files the correction through ACE, and CBP recalculates without the IEEPA surcharge. Follow the 7-step filing guide for the process.

Industry-Specific Guidance
Pharmaceutical and Chemical Importers
New Jersey’s pharmaceutical corridor means the state has among the highest concentrations of pharma importers in the country. APIs from China, finished formulations from India, and specialty chemicals from multiple IEEPA-targeted countries all carried surcharges that are now refundable.
Pharma entries are often complex, with multiple tariff lines and duty components. Your refund claim needs to isolate the IEEPA-specific duties (9903-series HTS codes) from other duty categories. This is standard work for experienced customs brokers, but verify that your broker is capturing every IEEPA line.
Estimated pharma IEEPA exposure: A mid-size NJ-based pharma importer bringing in $50M-$100M in APIs and finished products from China/India could be looking at $5M-$15M in recoverable duties.
Retail and Consumer Goods Distributors
New Jersey’s warehouse corridor serves the entire Northeast retail market. If you operate a distribution business that imports consumer goods, your IEEPA exposure is likely concentrated in Chinese-origin merchandise — electronics, apparel, home goods, toys — carrying the 20-34% surcharge rate.
Many NJ distributors import through Port Newark and store goods in nearby warehouses before shipping to retailers across the region. Your entry data should be relatively concentrated in District 4601, which simplifies the filing process compared to multi-district importers.
Food and Beverage Importers
The Mid-Atlantic is a major food import gateway, with specialty items from around the world entering through Philadelphia, Newark, and Wilmington. Chinese specialty foods, Mexican produce, and agricultural products from other targeted countries all carried IEEPA surcharges. The country-by-country refund guide details which rates applied to each origin.
Automotive Importers
Baltimore’s role as a top vehicle import port means Mid-Atlantic auto importers have significant IEEPA exposure. A single imported vehicle from an IEEPA-targeted country could carry $5,000-$15,000 in surcharges, and auto parts imports add more on top. If you import vehicles or parts through Baltimore, prioritize these high-value entries in your recovery plan.
The Warehouse Corridor Advantage
New Jersey’s extraordinary warehouse density — over a billion square feet — creates a unique dynamic for IEEPA recovery. Understanding how the warehouse ecosystem interacts with import patterns can help Mid-Atlantic importers maximize their refund.
Warehouse as Distribution Hub
Many Mid-Atlantic warehouses serve as distribution nodes: goods enter through regional ports, are stored or processed in NJ warehouses, and are shipped to retailers and consumers throughout the Northeast. The companies operating these warehouses are often the importers of record — and the holders of IEEPA refund rights.
If you operate a distribution warehouse in New Jersey that receives imported goods, verify that you are the importer of record on the customs entries. If you are, the IEEPA refund belongs to you. If your supplier or a trading company is the importer of record, the refund rights may rest with them instead.
Cross-Docking Operations
Some NJ warehouse operations don’t actually store goods — they cross-dock, moving containers from port to outbound trucks in hours. Cross-docking doesn’t change the customs entry process; the IEEPA duties were still assessed at import. Your refund claim is based on the entry, not the warehousing treatment.
The E-Commerce Fulfillment Boom
New Jersey has become a major hub for e-commerce fulfillment, with Amazon, Walmart, and dozens of other retailers operating massive warehouses throughout the state. These operations are fed by imports — often from China — that carried IEEPA surcharges. E-commerce fulfillment companies that are the importer of record on these entries have significant refund claims.
Even smaller e-commerce operators who import inventory and store it in NJ fulfillment centers should investigate their IEEPA exposure. The cumulative total across a year of steady importing can be substantial, even for modest-volume sellers. Check your eligibility and refund estimate.
Port Proximity and Speed
The Mid-Atlantic’s advantage is proximity: goods can move from ship to warehouse to consumer faster here than in almost any other import corridor. That same proximity advantage applies to IEEPA recovery — your broker is nearby, the CBP offices are nearby, and the legal infrastructure (including the CIT in New York) is all within reach. Leverage that proximity to move fast on your recovery.
Calculating Your Mid-Atlantic IEEPA Refund
- Pull ACE data for all port districts where you have entries (4601, 1101, 1303, and any others)
- Consolidate across brokers — if you use different brokers for different ports or transport modes
- Filter for 9903.01 and 9903.02 HTS codes and sum associated duties
- Map liquidation dates for protest window tracking
- Calculate total by recovery path — PSC-eligible, protest-eligible, and CIT-eligible amounts
Estimated refund ranges for Mid-Atlantic importers:
| Importer Profile | Annual Import Value | Estimated IEEPA Refund |
|---|---|---|
| Small specialty/food importer | $2M-$10M | $200K-$1.5M |
| Mid-size NJ distributor | $15M-$60M | $2M-$10M |
| Pharmaceutical importer | $30M-$100M | $4M-$18M |
| Large multi-category operation | $80M-$250M | $10M-$40M |
Frequently Asked Questions for Mid-Atlantic Importers
I’m headquartered in New Jersey but import through both Newark and Baltimore. Do I file with one CBP district?
No. You file with each CBP district where entries were processed. Newark entries (District 4601) are filed with the NY/NJ CBP office, and Baltimore entries (District 1303) are filed with the Baltimore CBP office. Your customs broker handles these filings electronically through ACE, so the administrative burden isn’t as heavy as it sounds — but you need to ensure both districts’ entries are captured in your refund claim.
My broker says some of my entries have both Section 232 (steel) and IEEPA duties. Which is refundable?
Only the IEEPA component (duties under HTS headings 9903.01 and 9903.02) is refundable through this process. Section 232 duties on steel and aluminum are a separate tariff program and are not affected by the Supreme Court’s IEEPA ruling. Your broker should be able to separate the two components on each entry. This is common for metal importers in the Mid-Atlantic region.
I use a freight forwarder that handles customs clearance. Can they file my IEEPA refund?
Your freight forwarder likely uses a licensed customs broker for the actual entry filings. That broker is the one who needs to file your post-summary corrections or protests. Contact your forwarder to identify which broker handled your entries, then engage that broker directly about IEEPA recovery. Don’t assume your forwarder is handling it — verify and get confirmation of specific actions being taken.
Filing Timeline and Urgency
The Rolling Deadline Problem
Mid-Atlantic importers with entries across multiple port districts face a rolling deadline situation. Your Newark entries liquidated on different dates than your Philadelphia or Baltimore entries, which means protest deadlines don’t fall on a single date — they’re spread across weeks or months.
This rolling deadline dynamic requires systematic monitoring. If you’re tracking liquidation dates manually, it’s easy to miss an entry that falls between monitoring cycles. Automated tracking through a professional impact assessment eliminates this risk by flagging every entry with an approaching deadline.
The Processing Queue Reality
CBP District 4601 (Newark/JFK) will face one of the highest volumes of IEEPA claims in the country. Districts 1101 (Philadelphia) and 1303 (Baltimore) will have smaller but still significant queues. Filing early gives you the best position in every queue simultaneously.
The Bottom Line
For Mid-Atlantic importers, the math is clear: substantial IEEPA duties were paid across a multi-port region, the refund mechanism is well-established, and the deadlines are real. Every day of inaction is a day of delayed recovery and increased deadline risk. The infrastructure to file is ready — your brokers know how to do this, the ACE system is functional, and professional advisory services are available. The only missing ingredient is your decision to start.
Take Action Now
Mid-Atlantic importers benefit from proximity to the largest East Coast port infrastructure — but that also means you’re competing with a massive number of other importers for CBP processing bandwidth. The cost of waiting is real: delayed filings mean delayed refunds and increased risk of missing protest windows.
