US Customs Clearance Process: Fees, Processing Time, Payments & What Status Messages Mean
Introduction
US customs clearance is the process of declaring imported goods to US Customs and Border Protection (CBP), paying duties and taxes, and obtaining release to move cargo inland. For most shipments, customs clearance takes 1 to 5 business days. Here is what you need to know in 2026:
Key Takeaways
- Typical clearance takes 1 to 5 business days. Air cargo often clears in under 24 hours. Ocean cargo with an inspection can take a week or more.
- The full process is 7 steps: file ISF (ocean), submit entry on CBP Form 3461, pay duties, file entry summary on CBP Form 7501 within 10 working days, get cargo released, then keep records for the 5 year audit window.
- "In progress" means CBP is reviewing the entry. "Started" means filing has been submitted. "Completed" or "complete" means cargo has been released and a delivery order has been issued.
- Customs fees include duties (HTS-based), Merchandise Processing Fee, Harbor Maintenance Fee on ocean cargo, and broker fees. ACH Direct is the fastest payment method.
- Most commercial shipments require a licensed customs broker, a customs bond for entries over $2,500, and clean documentation (commercial invoice, packing list, BOL or AWB, ISF for ocean).
- After clearance, delivery typically happens within 1 to 3 business days for domestic moves, depending on inland distance.
- Timing: Typical clearance takes 1 to 5 business days once documents are filed. Air cargo often clears in under 24 hours. Ocean cargo with inspections can take a week or more.
- Process: File ISF (for ocean), submit entry (CBP Form 3461), pay duties, file entry summary (CBP Form 7501) within 10 working days, release cargo for inland delivery.
- Status meanings: "In progress" means CBP is reviewing. "Started" means filing has been submitted. "Complete" means cargo is released.
- After clearance: Delivery typically happens within 1 to 3 days of customs release, depending on inland distance.
This guide covers the full US customs clearance process, how long each stage takes, what each customs status means, documents required, fees involved, and what happens after clearance.
What Is US Customs Clearance?
US customs clearance is the mandatory process by which imported goods are declared to US Customs and Border Protection (CBP), duties and taxes are paid, and cargo is released for onward movement in the United States. Every commercial shipment entering the US must go through customs clearance, regardless of mode (ocean, air, truck, rail) or value.
The clearance process has three main components:
- Advance filing (ISF for ocean, AMS for ocean and air)
- Entry filing and duty payment when cargo arrives
- Entry summary and compliance review within 10 working days
How Long Does Customs Clearance Take?
Customs clearance time varies by shipping mode, cargo type, and whether CBP flags the shipment for inspection.
| Shipping Mode | Typical Clearance Time | With Inspection |
|---|---|---|
| Air freight | Same day to 24 hours | 1 to 3 business days |
| Ocean FCL | 1 to 3 business days | 3 to 7 business days |
| Ocean LCL | 2 to 5 business days | 5 to 10 business days |
| Express parcel | Hours to 1 business day | 2 to 3 business days |
| Truck / rail | Hours to 1 business day | 1 to 2 business days |
How Long Does US Customs Take to Process a Package?
For a typical commercial package arriving by air, US customs processes it within 24 to 48 hours after arrival. Express courier shipments often clear in under 12 hours. Packages flagged for inspection can take 2 to 5 business days. Total time from arrival to delivery is usually 1 to 4 business days.
Factors That Affect Customs Clearance Time
- Accurate paperwork. Clean documentation clears faster. Errors or missing documents trigger hold times measured in days.
- Duty payment. Cargo is not released until duties are paid. ACH payment is fastest.
- Inspection status. CBP randomly selects shipments for exam. Exams add 1 to 10 days depending on type.
- FDA, USDA, or other agency review. Food, drugs, medical devices, and agricultural products require additional agency clearance.
- Importer of Record status. First-time importers and non-resident importers face longer review.
- Filing timeliness. ISF must be filed 24 hours before vessel departure. Late ISF triggers $5,000+ penalties and delayed clearance.
The US Customs Clearance Process: 7 Steps
Step 1: File Importer Security Filing (ISF 10+2)
For ocean imports only. ISF must be filed at least 24 hours before the vessel departs the origin port. 10 data elements from the importer plus 2 from the carrier. Late filing: $5,000 penalty plus potential cargo holds. For the full ocean-import workflow that handles ISF, AMS, and entry filing in one shipment record, see Ocean Import Freight Management Software.
Step 2: Submit Entry Documentation (CBP Form 3461)
When cargo arrives at the port of entry, the licensed customs broker submits the entry filing to CBP. This includes commercial invoice, packing list, bill of lading or air waybill, and other required documents.
Step 3: CBP Review
CBP reviews the entry. Outcomes:
- Released: Cargo cleared, ready for movement
- Flagged for exam: Physical inspection required
- Additional information needed: Broker must provide more documentation
- Held: Compliance issue or agency review triggered
Step 4: Pay Duties, Taxes, and Fees
Duties are based on Harmonized Tariff Schedule (HTS) classification and country of origin. Pay via ACH (fastest), check, or periodic monthly statement (PMS) for frequent importers.
Step 5: Submit Entry Summary (CBP Form 7501)
Within 10 working days of release, file the entry summary. This confirms final valuation, duty calculation, and classification.
Step 6: Cargo Release and Delivery Order
Customs broker coordinates release with the carrier. Delivery order is issued, allowing the cargo to move from the port to the final destination.
Step 7: Post-Release Compliance
CBP can audit entries up to 5 years after release. Maintain clean records: commercial invoices, packing lists, HTS classification worksheets, and payment records.
Automated Manifest System (AMS) for Air and Ocean
AMS is a CBP system that requires carriers to electronically transmit cargo information before arrival in the US.
Ocean AMS
Filed by the ocean carrier at least 24 hours before loading at the foreign port. This aligns with the ISF 10+2 timeline.
Air AMS
Filed by the air carrier at least 4 hours prior to arrival in the US for most flights. For short-haul flights from nearby points where flight time is under 4 hours, the filing deadline is at wheels-up (departure) from the origin.
AMS Consequences
Late or missing AMS filing triggers holds at arrival and can delay clearance by days. For forwarders, automated AMS filing is a core TMS feature. See Freight Integrations Software for Forwarders for how AMS, ISF, and entry filing connections plug directly into the shipment record.

Customs Clearance Status Meanings
Tracking shows various customs status messages. Here is what each means:
"Import Customs Clearance Started"
Entry documentation has been submitted to CBP. Review is underway. No action needed. Typical duration: hours to 1 to 2 business days.
"Customs Clearance In Progress"
CBP is actively reviewing the entry. This status can last from a few hours up to several days depending on workload and whether additional review is needed.
"Destination Customs Clearance In Progress"
Same as above but specific to the destination country's customs. For shipments destined to the US, this means CBP is processing.
"Additional Customs Clearance Information Is Needed"
CBP has requested more information or documentation. The broker must respond before clearance continues. Action needed: contact the broker to provide the requested information.
"Customs Inspection - Import"
Cargo has been flagged for physical inspection. Duration varies: document exam (1 day), intensive exam (3 to 5 days), or non-intrusive inspection (1 to 2 days).
"Shipment Completed Customs Clearance Process"
Cargo has been released by CBP. A delivery order has been issued. The shipment can move from the port to the final destination.
"Import Customs Clearance Complete"
Same as "completed". Cargo has been released.
After Customs Clearance: How Long Does Delivery Take?
Once customs clearance is complete, delivery timing depends on inland distance and mode:
| Inland Movement | Typical Delivery Time After Clearance |
|---|---|
| Port to nearby warehouse (under 100 miles) | Same day to 1 business day |
| Domestic trucking (500 to 1,000 miles) | 1 to 3 business days |
| Domestic trucking (cross-country) | 3 to 5 business days |
| Express delivery (air to final mile) | 1 to 2 business days |
| Rail intermodal | 3 to 7 business days |
How to Pay Customs Clearance Fees
Duties, taxes, and fees must be paid before CBP releases cargo. Payment methods:
- ACH Direct (preferred). Electronic debit from the importer's bank account. Fastest method. No processing delay.
- Statement Processing Payment (SPP). CBP sends a monthly statement for importers with regular volume. Payment due by a set date each month.
- Check. Slower processing. Typically handled by the customs broker.
- Customs bond. Required for entries over $2,500. Acts as financial guarantee to CBP. Single-entry bond or continuous bond.
For frequent importers, setting up ACH Direct with CBP and maintaining a continuous bond streamlines clearance significantly.
Air Freight Customs Clearance
Air freight customs clearance is typically faster than ocean because:
- Transit times are shorter (typically 1 to 3 days vs weeks for ocean)
- AMS filing deadline is tighter (4 hours prior to US arrival, or at wheels-up for short-haul flights)
- Air cargo inspection types are generally faster than ocean FCL inspections
- Air shippers tend to have cleaner documentation due to the urgency of time-sensitive cargo
Typical air freight customs clearance:
- Documentation submitted before arrival via e-AWB and AMS
- CBP review begins at or before arrival
- Clearance often complete within 24 hours of landing
- Release and delivery order issued for pickup
Air AMS Filing Deadlines
Air AMS deadlines depend on flight length:
- Most flights (over 4 hours flight time): Filed at least 4 hours prior to arrival in the US.
- Short-haul flights (under 4 hours): Filed at wheels-up from the origin airport, meaning immediately as the flight departs.
Missing the AMS filing deadline results in clearance holds, fines, and potentially diverted cargo.
Who Can File Customs Clearance?
Customs clearance must be filed by:
- A licensed customs broker. Most importers use a broker because the process is complex and errors are costly.
- The importer directly. Self-filing is legal but requires CBP broker licensing for commercial volume or significant in-house expertise.
For most freight forwarders and shippers, using a licensed broker is the practical choice. Many TMS and FMS platforms integrate with customs brokers directly, which speeds filing and reduces errors.

Frequently Asked Questions
How long does customs clearance take?
Typical customs clearance takes 1 to 5 business days. Air freight often clears within 24 hours of arrival. Ocean FCL typically clears in 1 to 3 business days. Ocean LCL takes 2 to 5 business days. Shipments flagged for inspection can take 3 to 10 business days. Accurate paperwork and timely duty payment speed the process significantly.
What is customs clearance?
Customs clearance is the mandatory process of declaring imported goods to a country's customs authority (in the US, that is Customs and Border Protection or CBP), paying any duties and taxes owed, and getting cargo officially released so it can leave the port or terminal. Every commercial shipment entering the US goes through customs clearance, regardless of mode or value. A licensed customs broker normally files the entry on behalf of the importer.
What does "customs processing" mean?
"Customs processing" means the customs authority is actively reviewing your shipment's entry documentation. For US imports, it means CBP has received the entry and is checking the declared HTS classification, valuation, country of origin, and supporting documents before deciding whether to release the cargo, request more information, or flag it for inspection. No action is needed from the consignee unless the broker requests it.
What does "customs clearance in progress" mean?
"Customs clearance in progress" means CBP is actively reviewing the entry documentation for your shipment. No action is needed from you. The status typically lasts from a few hours up to several days depending on CBP workload and whether additional review or inspection is required.
What does "clearance processing completed" or "customs clearance complete" mean?
"Clearance processing completed" and "customs clearance complete" both mean CBP has released your cargo and issued a delivery order. The shipment is now legally authorized to leave the port or terminal and move to its final destination. The status appears once duties have been paid, the entry has been accepted, and no further inspection or documentation is outstanding.
How much does customs clearance cost in the USA?
US customs clearance cost is made up of several layers. Import duties depend on the HTS classification and country of origin and can range from 0% to 30%+ of cargo value. The Merchandise Processing Fee (MPF) is 0.3464% of declared value with a minimum and maximum cap. Ocean cargo also pays the Harbor Maintenance Fee (HMF) at 0.125% of value. Customs broker fees for a standard single entry typically run $100 to $250. A single-entry bond costs around $50 to $100 per shipment, while a continuous bond runs $400 to $600 per year and covers all entries. For frequent importers, a continuous bond plus ACH Direct is the lowest per-shipment cost setup.
After customs clearance, how long does delivery take?
After customs clearance is complete, delivery typically takes 1 to 3 business days for domestic trucking within 1,000 miles. Express air-to-final-mile takes 1 to 2 business days. Cross-country trucking takes 3 to 5 business days. Rail intermodal takes 3 to 7 business days. Delivery timing depends on inland distance and shipping mode, not on customs clearance itself.
How do I pay customs clearance fees?
The fastest method is ACH Direct, an electronic debit from the importer's bank account to CBP. Other methods include Statement Processing Payment (monthly billing for regular importers), check payment via the customs broker, and using a customs bond as financial guarantee. For frequent importers, ACH Direct plus a continuous bond streamlines clearance.
What documents are needed for US customs clearance?
Standard documents include commercial invoice, packing list, bill of lading (ocean) or air waybill (air), ISF 10+2 (ocean imports), CBP Form 3461 (entry), and CBP Form 7501 (entry summary). Additional documents may be required for FTA claims (Certificate of Origin), food and drug imports (FDA Prior Notice), and regulated commodities. The Importer of Record Number (IOR) and a customs bond are also required for commercial entries above $2,500.
How long does customs inspection take?
Customs inspection duration varies by type. A document exam usually takes 1 business day. A non-intrusive inspection (X-ray or VACIS) takes 1 to 2 business days. An intensive physical exam takes 3 to 5 business days. A CES exam by USDA or FDA can extend to 7 to 14 business days for food and drug imports. CBP does not announce inspections in advance; the broker sees the hold on the entry status.
Conclusion
US customs clearance is a multi-step process with multiple filing deadlines, payment methods, and status points. Understanding what each status means and how long each stage typically takes helps you set realistic delivery expectations and avoid penalties from late filings.
For freight forwarders, modern TMS platforms automate ISF, AMS, and entry filing, reducing the error rate and speeding clearance. Manual filing in Excel or standalone tools creates the errors that cause the clearance delays.
