For US importers and Amazon sellers, having a shipment flagged for a customs hold can be a stressful experience. Supply chains rely on predictable timelines, and any delay at the port directly impacts inventory availability and fulfillment metrics.
Understanding exactly what US Customs and Border Protection (CBP) is looking for—and what occurs once they finish looking—is essential for managing logistics smoothly.
What Happens After Customs Inspection?
Immediately after a customs inspection, CBP will update the shipment’s status in the Automated Commercial Environment (ACE) system.
If no issues are found, the cargo is released for its final delivery. If discrepancies or compliance issues are discovered, CBP may request additional documentation, assess further duties, transfer the cargo to another agency (like the FDA or EPA), or, in severe cases, seize the shipment.
Understanding the Customs Inspection Process
To anticipate what happens post-inspection, it is crucial to understand why and how CBP halts cargo in the first place.
Why Customs Inspects Shipments
CBP’s primary directives are to collect import revenue, protect US borders from illegal contraband, and ensure that imported goods comply with all federal safety and trade regulations. Inspections are the mechanism used to enforce these mandates.
Types of Customs Inspections
Not all inspections are created equal. They range from simple paperwork reviews to intensive physical unboxings at specialized facilities off-site.
How Shipments Are Selected for Inspection
CBP uses the Automated Targeting System (ATS) to assign a risk score to incoming cargo. Shipments are flagged based on historical data, the importer’s record, the country of origin, the type of commodity, or simply through random compliance checks.
Common Types of Customs Inspections
When shipping to the US, importers typically encounter specific CBP examination tiers:
Document Inspection
Before physical cargo arrives, CBP reviews the Entry Summary and manifest. If details are vague or suspicious, they will pause clearance to verify the paperwork.
X-Ray Examination (NII / VACIS Exam)
Also known as a Non-Intrusive Inspection (NII) or Vehicle and Cargo Inspection System (VACIS) exam. The container is driven through a massive X-ray machine to ensure the physical contents match the manifest without breaking the container seal.
Physical Cargo Inspection (Tailgate Exam)
If the X-ray shows anomalies, CBP will conduct a Tailgate Exam. An officer breaks the seal, opens the container doors, and visually inspects the first few rows of cargo.
Intensive Examination (CET / MET Exam)
This is the most thorough and costly inspection. The container is moved to a Centralized Examination Station (CES).
- CET (Contraband Enforcement Team): Focuses on illegal drugs, weapons, or unmanifested goods.
- MET (Merchandise Examination Team): Focuses on trade compliance, intellectual property rights (IPR) violations, and accurate valuation.
Agriculture and Biosecurity Inspection
Conducted by CBP Agriculture Specialists (often in conjunction with the USDA), this inspection targets wooden packaging, food products, and botanical items to prevent invasive pests and diseases from entering the US.
What Happens Immediately After Customs Inspection?
Once the physical or documentary review is complete, the examining officer updates the entry status in the ACE portal. Your customs broker will receive an electronic notification indicating whether the hold has been lifted or if further action is required.
Possible Outcomes After Customs Inspection
Shipment Is Cleared and Released
This is the ideal outcome. CBP issues an electronic release (often corresponding to CBP Form 3461), authorizing the terminal to release the container to your drayage carrier for inland transport.
Additional Information Is Requested
CBP may issue a CBP Form 28 (Request for Information). They might ask for detailed product schematics, proof of payment, or a breakdown of the supply chain to verify the country of origin.
Duties, Taxes, or Fees Are Assessed
If the inspection reveals that the goods were undervalued or classified under the wrong Harmonized Tariff Schedule (HTS) code, CBP will issue a CBP Form 29 (Notice of Action), adjusting the owed duties before release.
Cargo Is Held for Further Review
Sometimes CBP clears the cargo, but a Partner Government Agency (PGA) like the FDA, EPA, or DOT places a separate hold on the goods until their specific regulatory standards are verified.
Shipment Is Rejected or Seized
If the goods are counterfeit, illegal, or fail to meet US safety standards, CBP will issue a seizure notice. The importer will then have a window to petition the decision, export the goods back, or face cargo destruction.
How Long Does Customs Clearance Take After Inspection?
The timeline heavily depends on the examination type. A VACIS (X-ray) exam is usually completed within 24 to 48 hours. A Tailgate Exam might add a few days. However, an Intensive CES Exam can delay a shipment anywhere from one to three weeks, depending on port congestion and CES facility backlog.
Why Some Shipments Remain Delayed After Inspection
Even after the physical inspection concludes, your freight might not move immediately due to several administrative hurdles:
- Missing or Incorrect Documentation: Failure to provide a commercial invoice that matches the physical freight.
- Product Classification Issues: Disputes over the correct HTSUS code.
- Valuation Disputes: CBP suspects the declared value is artificially low to evade tariffs.
- Regulatory Compliance Concerns: Missing PGA forms (e.g., FDA Prior Notice, EPA TSCA forms).
- Random Secondary Examinations: In rare cases, clearing one agency’s inspection triggers a secondary review by another.
Customs Inspection Timeline by Transportation Method
| Shipping Method | Typical Inspection Time | Typical Release Time After Inspection |
| Air Freight | 1–2 Days | Same Day to 2 Days |
| Express Courier | Same Day | Same Day |
| Ocean Freight (LCL) | 2–7 Days | 1–5 Days |
| Ocean Freight (FCL) | 2–10 Days | 1–7 Days |
| Rail Freight | 1–5 Days | 1–3 Days |
| Truck Freight | Same Day to 3 Days | Same Day to 2 Days |
Common Reasons Customs Requests Additional Information
When a CBP Form 28 is issued, it is usually tied to one of the following red flags:
- Commercial Invoice Discrepancies: Vague descriptions like “Apparel” instead of “Women’s 100% Cotton Knitted T-Shirts.”
- Missing Certificates or Licenses: Lacking necessary permits for restricted goods.
- Incorrect HS Codes: Misclassification that affects duty rates.
- Country of Origin Verification: Suspicions of transshipment to avoid anti-dumping duties or Section 301 tariffs.
- Product Compliance Documentation: Missing manufacturer declarations.
Customs Inspection Costs Importers Should Know
CBP does not charge for the inspection itself, but the logistical costs associated with the inspection are entirely the importer’s responsibility:
- Inspection Fees: CES facilities charge fees for unloading, un-palletizing, and reloading the cargo.
- Storage Charges: Daily fees assessed by the CES or terminal while the cargo waits for inspection.
- Demurrage and Detention Fees: Penalties from the steamship line for using their container beyond the allotted free days.
- Additional Transportation Costs: Drayage fees to truck the container from the terminal to the off-site CES facility and back.
How Freight Forwarders Help After Customs Inspection
Navigating a customs hold is a collaborative effort. A competent freight forwarder adds value by:
- Coordinating With Customs Brokers: Ensuring seamless data flow between the broker and the local terminal.
- Providing Missing Documentation Quickly: Acting as a liaison between the overseas supplier and the US broker to source missing factory documents.
- Monitoring Shipment Status: Using ACE and terminal portals to track release codes in real-time.
- Reducing Clearance Delays: Pre-arranging inland trucking so the cargo moves the moment CBP lifts the hold.
What Importers Should Do If Their Shipment Is Held by Customs
If you receive notification of a hold, remain calm and act systematically:
- Contact Your Customs Broker: They are your legally authorized representative to CBP. Ask them to verify the exact type of hold in ACE.
- Review Customs Notices Carefully: Read any Form 28 or Form 29 thoroughly to understand exactly what CBP is demanding.
- Submit Requested Documents Promptly: Time is money. Provide clear, translated, and accurate documents to your broker immediately.
- Communicate With Your Freight Forwarder: Keep them updated so they can manage terminal storage fees and adjust inland transportation schedules.
How to Reduce the Risk of Customs Delays
While you cannot avoid random inspections, you can minimize targeted holds and ensure swift clearance if inspected:
- Ensure Accurate Documentation: Your Commercial Invoice and Packing List must be meticulously detailed.
- Use Correct HS Codes: Consult with a licensed Customs Broker before shipping to confirm your HTSUS classification.
- Verify Product Compliance Requirements: Know if your product requires FDA, EPA, or CPSC clearance before it leaves the origin port.
- Work With Experienced Freight Forwarders: Partner with logistics providers who have a strong track record in US trade compliance.
- Prepare for Duties and Taxes in Advance: Consider setting up a continuous customs bond and an ACH account with CBP for instant duty payment.
Customs Inspection vs Customs Clearance
Understanding the distinction helps clarify the import timeline:
| Feature | Customs Inspection | Customs Clearance |
| Definition | Physical or document review to verify compliance | The official approval and authorization for entry |
| Frequency | May or may not occur (targeted or random) | Required for all commercial imports |
| Impact | Can cause delays and incur logistical costs | The final release process allowing cargo movement |
| Focus | Focuses on compliance verification and risk assessment | Focuses on legal import authorization and duty collection |
Conclusion
A customs inspection is only one potential hurdle in the broader US import process. After an inspection concludes, shipments may be released immediately, held for additional documentation, assessed for further duties, or transferred for PGA review.
While the costs and delays associated with Intensive Exams can be frustrating, maintaining meticulous documentation, applying correct HTSUS classifications, and maintaining proactive communication with your customs broker and freight forwarder are the most effective strategies to navigate the process swiftly and protect your supply chain timeline.
