Processing and Inspection Procedures at Ports of Entry
Primary Inspection
At ports of entry, travelers and cargo undergo primary inspection where CBP officers review documents, verify identity, and assess admissibility. Officers use automated gates, biometric systems, and risk-based flags to prioritize inspections efficiently.
Secondary Inspection and Detention
Cases flagged for further review proceed to secondary inspection, where officers may conduct detailed document checks, searches, or refer travelers for additional processing. Detention can occur when evidence suggests a violation or heightened risk.
Trade Compliance and Cargo Processing
Entry Summary and Duty Assessment
Importers file entries through the Automated Commercial Environment, providing product details, country of origin, and supporting documentation. CBP reviews filings to ensure compliance and calculates applicable duties, taxes, and fees before releasing cargo.
Programs to Expedite Legitimate Trade
Cargo programs like ACE eManifest and trusted trader partnerships enable faster processing for low-risk shipments. Importers that meet security and compliance requirements benefit from reduced inspections and smoother supply chain flow.
Enforcement and Security Initiatives
Smuggling and Counterterrorism Efforts
CBP targets smuggling of drugs, weapons, and illicit goods through interdiction, intelligence sharing, and risk analytics. Security initiatives focus on detecting threats in aviation cargo, mail, and cross-border movements.
Worksite Enforcement and Remittances
I-9 verification audits and compliance initiatives aim to deter unauthorized employment. Enforcement actions may result in fines, notices of violation, or referrals to Homeland Security Investigations for criminal review.

FAQ
Reader questions
What happens if CBP finds an error on my I-94 or admission record?
Contact CBP’s Customer Service Center or use the CBP One app to request correction. Provide supporting documents such as boarding passes, passports, and any prior I-94 records to resolve discrepancies quickly.
Can CBP search my electronic devices at the border without suspicion?
Yes, officers can conduct routine searches of devices and media at ports of entry under border search authority. You may refuse a search, but refusal can lead to denial of entry or further inspection of devices.
How does Trusted Traveler enrollment affect processing at airports and land ports?
Programs like Global Entry and NEXUS use biometric identifiers and automated gates to expedite entry. Members often receive shorter lines, reduced questioning, and access to dedicated lanes for faster processing.
What triggers secondary inspection or referral for further review?
Officers may refer travelers based on inconsistencies in documents, unusual travel patterns, or automated risk indicators. Additional review can include detailed questioning, fingerprinting, or medical inspections as required by law.
