Centralized Examination Station (CES)

What is a Centralized Examination Station (CES)?

A Centralized Examination Station (CES) is a private facility authorized by U.S. Customs and Border Protection (CBP) where imported cargo is sent for inspection before being released into U.S. commerce. When CBP selects a shipment for examination, it is diverted from the port to a CES, where customs officers can inspect the goods in a controlled environment.

These inspections are used to verify compliance with U.S. laws related to tariffs, contraband, intellectual property, agriculture, and trade regulations.

Why Are Shipments Sent to a CES?

Shipments may be flagged for examination due to:

  • Random selection
  • Suspicious or incomplete documentation
  • High-risk commodities (e.g., electronics, pharmaceuticals)
  • Potential misclassification or undervaluation
  • Agricultural concerns (soil, pests, or prohibited materials)

What Happens at a CES?

Once selected, the cargo is transported to the designated CES facility, where:

  1. CBP officers conduct physical inspections, X-rays, or sampling
  2. Goods are repacked and resealed after the exam
  3. CBP clears or detains the shipment based on findings
  4. All costs associated with the move and exam (drayage, devanning, storage) are billed to the importer

Impact on Importers and Shippers

  • Delays in cargo release—ranging from a few days to a few weeks
  • Additional costs, including drayage, handling, and storage fees
  • Increased compliance scrutiny for repeat exam flags
  • Possible penalties if noncompliance or violations are found

Example in Practice

An importer brings in a shipment of auto parts from Germany. CBP flags the cargo for a Tail Gate Exam, and it is redirected to a CES near the Port of Baltimore. After X-ray screening and a brief physical inspection, the shipment is cleared and returned to the importer’s freight forwarder for final delivery.
