Customs clearance at Chicago O’Hare International Airport (ORD) is the process of moving imported goods through U.S. Customs and Border Protection to legally enter the United States. As the sixth-busiest cargo airport in the world and a top-five U.S. port of entry by value, ORD handles over $200 billion in trade annually — making its clearance process one that every importer shipping through the Midwest needs to understand.
Whether you are importing electronics from Shenzhen, pharmaceuticals from Frankfurt, or auto parts from Nagoya, the ORD clearance workflow follows a specific sequence governed by federal regulations. This guide breaks down each step, the legal framework behind it, what it costs, and where importers most often go wrong.
What Is ORD Customs Clearance?
ORD customs clearance: The complete regulatory process by which imported goods arriving at Chicago O’Hare International Airport (CBP port code 3901) are reviewed, assessed for duties and compliance, and released by U.S. Customs and Border Protection for entry into U.S. commerce.
O’Hare operates one of the largest Centralized Examination Stations (CES) in the United States and hosts a full CBP Field Office under the Chicago Field Office jurisdiction. The airport has dedicated cargo facilities spanning over 5 million square feet, operated by major cargo handlers including LSG Sky Chefs, Swissport, and Alliance Ground International.
ORD is classified as a designated port of entry under 19 CFR § 101.3. This means it has a full complement of CBP officers, import specialists, and agricultural inspectors stationed on-site. For importers, this translates to faster processing than at non-designated ports — but also higher scrutiny because of the volume and diversity of goods passing through.
Key statistics about ORD as an import hub:
- Trade volume: Over $200 billion in total trade value annually (CBP data)
- Cargo throughput: Approximately 1.85 million metric tons of cargo per year
- Top import origins: China, Germany, Japan, India, United Kingdom
- CBP port code: 3901
- Operating airlines (cargo): FedEx, UPS, Cathay Cargo, Lufthansa Cargo, Korean Air Cargo, and 30+ others
If you need a licensed customs broker near O’Hare, you can search all CBP-licensed customs brokers or browse brokers by state to find professionals familiar with ORD procedures.
How Customs Clearance Works at ORD: Step-by-Step
The clearance process at ORD follows the same federal framework as any U.S. port of entry, but air cargo moves faster than ocean freight — which means every step has a tighter window. Here is the full workflow from cargo departure to final release.
Step 1: Pre-Arrival Filing
Before your goods arrive at ORD, your customs broker (or you, if self-filing) submits entry documents electronically through the Automated Commercial Environment (ACE) portal. Required documents include:
- CBP Form 3461 (Entry/Immediate Delivery) — requests release of the goods
- Commercial invoice — describes the goods, their value, and origin
- Air waybill (AWB) — the air cargo equivalent of a bill of lading
- Packing list — itemized cargo contents
- HTS classification — the tariff code from hts.usitc.gov determining your duty rate
For air cargo, CBP requires advance electronic information at least 4 hours before arrival for non-consolidated shipments. Consolidated cargo (multiple shippers on one master air waybill) requires filing before the cargo is loaded on the aircraft at the foreign airport.
Step 2: Cargo Arrival and Manifest Review
When the aircraft lands at ORD, the airline files an electronic manifest with CBP confirming the cargo on board. CBP’s Automated Targeting System (ATS) runs risk assessments against the manifest, comparing it to your pre-filed entry data. This happens within minutes.
Step 3: CBP Document Review
CBP import specialists review your entry documents for accuracy. They check the HTS classification, declared value, country of origin, and whether any Partner Government Agency (PGA) requirements apply — for example, FDA clearance for food or pharmaceuticals, or USDA-APHIS inspection for agricultural products.
Step 4: Exam Determination
CBP either releases the shipment or selects it for examination. There are three exam types:
- Document review (DOCS) — CBP requests additional paperwork but does not physically touch cargo
- Tailgate exam (TAIL) — a partial physical inspection at the cargo facility
- Intensive exam (VACIS/X-ray or full) — cargo is moved to a CES for thorough inspection
At ORD, approximately 3–5% of air cargo shipments are selected for physical examination, according to industry estimates. The selection is risk-based, not random.
Step 5: Duty Assessment and Payment
Once CBP is satisfied, duties and fees are assessed based on your entry summary (CBP Form 7501). Payment is made electronically through ACE. If you have a continuous bond (CBP Form 301), duties are paid periodically. Single-entry bonds require payment before release.
Step 6: Cargo Release
CBP issues an electronic release message through ACE. Your freight forwarder or broker coordinates with the cargo handler at ORD to pick up the goods. At this point, the shipment is legally in U.S. commerce.
Average release timelines at ORD:
- Pre-cleared, no exam: 2–5 hours after arrival
- Document review hold: 1–2 business days
- Physical exam: 3–5 business days
- PGA hold (FDA, USDA): 3–7+ business days
Regulatory and Legal Framework
Customs clearance at ORD operates under the same federal statutes and regulations as every U.S. port. Understanding the key legal provisions helps importers anticipate requirements and avoid penalties.
19 USC § 1484 — this is the core statute requiring importers to file entry documentation for all imported merchandise. It establishes the legal obligation to declare goods, classify them correctly, and pay applicable duties. Failure to comply can result in penalties under 19 USC § 1592, which authorizes fines up to four times the duty owed for negligent violations and the domestic value of the goods for fraud.
19 CFR Part 141 — governs entry of merchandise, including the requirement that entries must be filed within 15 calendar days of arrival. At a fast-moving air port like ORD, most entries are filed within hours, not days — but the 15-day window is the legal backstop.
19 CFR Part 113 — covers customs bonds. Any commercial shipment valued over $2,500 requires a customs bond. At ORD, continuous bonds are standard for regular importers, typically set at 10% of annual duty payments (minimum $50,000). Single-entry bonds cost $5–$15 per $1,000 of shipment value.
19 CFR § 151.16 — establishes CBP’s authority to examine merchandise. This is the regulation that authorizes physical inspections, VACIS scans, and laboratory sampling at ORD’s CES facilities.
For shipments subject to anti-dumping or countervailing duties (AD/CVD), importers should reference the AD/CVD orders database maintained by the International Trade Administration. AD/CVD goods entering ORD face additional scrutiny and require cash deposits at the time of entry.
Real-World Scenarios: ORD Clearance in Practice
Understanding the theory is one thing. Here is what ORD clearance actually looks like for different types of importers.
Scenario 1: Electronics Importer (Standard Clearance)
A Chicago-based electronics distributor imports 500 units of consumer routers from Shenzhen, China. The shipment arrives on a Cathay Cargo flight. Their customs broker pre-filed the entry 24 hours before arrival with an HTS code of 8517.62.0090 (machines for reception, conversion, and transmission of data) at a 0% duty rate. CBP’s automated system matches the entry to the manifest, finds no anomalies, and releases the shipment 3 hours after landing. Total customs-related cost: broker fee ($150) + merchandise processing fee ($31.67) + bond premium ($0 — existing continuous bond). Time from landing to pickup: 4 hours.
Scenario 2: Food Importer (PGA Hold)
A specialty food company imports high-end olive oil from Italy. The shipment is subject to FDA Prior Notice requirements under the Bioterrorism Act. The broker files the Prior Notice through the FDA FURLS system 15 hours before arrival. However, FDA selects the shipment for a label review. The cargo sits at ORD for 4 business days while FDA confirms the nutritional labels meet 21 CFR Part 101 requirements. Cost impact: 4 days of warehouse storage at $85/day ($340) on top of normal brokerage and duties. Importers of food, pharmaceuticals, and other FDA-regulated goods can find experienced brokers through our specialty directory.
Scenario 3: Auto Parts (AD/CVD Flagged)
A Midwest auto manufacturer imports brake rotors from China, which are subject to anti-dumping duties under AD/CVD order A-570-846. The importer must deposit estimated AD duties of 66.71% at the time of entry — on top of the standard 2.5% Column 1 tariff. CBP at ORD flags the shipment for document review to verify the country of origin and producer. Clearance takes 2 business days. The cash deposit on a $50,000 shipment: $33,355. This is why AD/CVD awareness before shipping is critical.
| Scenario | Shipment Type | Exam Type | Clearance Time | Extra Costs |
|---|---|---|---|---|
| Electronics (standard) | Consumer routers | None | 3–4 hours | $0 extra |
| Food (PGA hold) | Olive oil | FDA label review | 4 business days | $340 storage |
| Auto parts (AD/CVD) | Brake rotors | Document review | 2 business days | $33,355 duty deposit |
| Pharmaceutical (full exam) | Generic APIs | Intensive/CES | 5–7 business days | $500–$1,200 exam + storage |
Common Mistakes and Misconceptions
Thousands of shipments clear ORD every day without incident. But when problems occur, they almost always trace back to a short list of preventable errors.
Mistake 1: Late or missing pre-filing. The single biggest cause of delays at ORD is failing to submit entry documents before cargo arrives. Without pre-filing, your goods sit in general order (GO) status — generating storage charges of $75–$150/day — while paperwork catches up. After 15 days in GO status, CBP can seize and auction the goods under 19 CFR § 127.11.
Mistake 2: Wrong HTS classification. An incorrect tariff code can mean the difference between 0% duty and 25% duty. It can also trigger CBP holds when the declared classification does not match the product description. Use the official Harmonized Tariff Schedule and consider requesting a binding ruling from CBP for complex products.
Mistake 3: Undervaluing goods. CBP officers at ORD are experienced with common valuation schemes. Under 19 USC § 1401a, transaction value is the primary appraisal method. Declaring a lower value to reduce duties is customs fraud — penalties start at the duty owed and escalate to seizure of merchandise.
Mistake 4: Ignoring PGA requirements. ORD handles a huge volume of FDA-regulated goods (food, drugs, medical devices, cosmetics). Forgetting to file FDA Prior Notice or USDA import permits does not just delay your shipment — it can result in refusal of admission. The goods get re-exported at your expense.
Mistake 5: Assuming your freight forwarder handles customs. A freight forwarder moves cargo. A customs broker clears it through CBP. These are two different functions. Some companies do both, but many freight forwarders are not licensed customs brokers. Verify your broker’s license number with CBP or through our broker search tool.
Tools and Resources for ORD Importers
Having the right tools cuts clearance time and reduces errors. Here are the essential resources for anyone importing through O’Hare.
ACE Portal (ace.cbp.dhs.gov): The mandatory electronic system for filing all entry documents with CBP. Your broker uses ACE on your behalf, but importers with an ACE Portal account can track their own shipment status in real time.

Cost Breakdown: What ORD Clearance Actually Costs
Every importer wants to know the bottom line. Here is a realistic cost breakdown for a standard commercial air cargo shipment clearing ORD.
| Cost Component | Typical Range | Notes |
|---|---|---|
| Customs broker fee | $125–$250 per entry | Higher for complex entries (PGA, AD/CVD) |
| Merchandise Processing Fee (MPF) | 0.3464% of value ($31.67 min, $614.35 max) | Per entry, set by CBP |
| Harbor Maintenance Fee | N/A for air cargo | Only applies to ocean shipments |
| Continuous bond (annual) | $300–$600/year | Required for frequent importers |
| Single-entry bond | $5–$15 per $1,000 value | One-time per shipment |
| CES exam fee (if selected) | $250–$1,200 | Charged by the CES operator, not CBP |
| Warehouse storage (if held) | $75–$150/day | Varies by cargo handler at ORD |
| Duties and taxes | Varies by HTS code | 0%–50%+ depending on product and origin |
For a $25,000 electronics shipment at 0% duty with no exam, total clearance costs run approximately $280–$370 (broker fee + MPF + bond premium proration). For a $25,000 food shipment requiring FDA review and 3 days of storage, costs jump to $600–$850 before any duties.
Frequently Asked Questions
What is ORD customs clearance?
ORD customs clearance is the process of getting imported goods through U.S. Customs and Border Protection at Chicago O’Hare International Airport. It involves filing entry documents, paying applicable duties and fees, passing CBP inspections, and obtaining release of cargo. O’Hare is one of the largest air cargo ports in the United States, processing over $200 billion in trade annually.
How does the customs clearance process work at ORD?
The process begins before your cargo lands. Your customs broker files entry documents electronically through the ACE Portal, including the entry summary (CBP Form 7501), commercial invoice, and air waybill. CBP reviews the filing, determines whether an exam is needed, and either releases the shipment or holds it for inspection. Most pre-cleared air cargo at ORD is released within 2–5 hours of arrival.
Do I need a customs broker to clear goods through ORD?
You are not legally required to use a customs broker — importers can self-file with CBP under 19 USC § 1484. However, the complexity of tariff classification, duty calculation, and regulatory compliance makes professional brokerage strongly advisable. At a high-volume port like ORD, errors cause compounding delays. Over 90% of commercial importers use a licensed customs broker, and you can search all CBP-licensed customs brokers to find one near O’Hare.
How long does customs clearance take at O’Hare Airport?
Standard air cargo clearance at ORD takes 2–5 hours after aircraft arrival when entry documents are pre-filed and no exam is required. If CBP orders an intensive exam or a shipment triggers a hold from another agency (FDA, USDA), clearance can take 3–7 business days. Shipments flagged for anti-dumping or countervailing duty review may take longer depending on documentation requirements.
What is the most common mistake importers make at ORD?
The most common mistake is failing to pre-file entry documents before the cargo arrives. At ORD, where cargo volumes are extremely high, late filings push your shipment to the back of the queue and can trigger demurrage and storage charges of $75–$150 per day. A close second is incorrect HTS classification, which can lead to duty underpayment, CBP holds, and potential penalties under 19 USC § 1592.
