When shipping cargo internationally, understanding how to handle detained shipments is essential. A detained shipment can disrupt your supply chain, increase demurrage costs, and delay product distribution. For importers into the United States, understanding customs hold management and the U.S. customs clearance process is essential for minimizing financial risk.
If your cargo has been flagged or placed on hold by U.S. Customs and Border Protection (CBP), immediate corrective action is critical.
This guide explains why shipments are detained, how the customs hold process works, and how professional customs brokerage services can help resolve detained cargo quickly.
Why Shipments Get Detained by U.S. Customs
CBP may detain cargo for several compliance-related reasons, including:
- Incorrect or incomplete customs documentation
- Improper HS code classification
- Undervaluation or declared value discrepancies
- Missing import permits
- Regulatory agency review
- Random customs inspection
- Inconsistent commercial invoice information
Businesses searching for “shipment detained by customs USA,” “customs hold release process,” or “how to clear a shipment on hold” are typically facing one of these issues.
The U.S. Customs Hold Resolution Process
When CBP places your cargo on hold, the resolution process generally involves:
- Identifying the official reason for the CBP hold
- Reviewing customs entry documentation
- Amending filing errors
- Submitting additional required documents
- Coordinating physical exams if required
- Paying additional duties, tariffs, or penalties (if applicable)
- Requesting formal release authorization
Every additional day at port may generate storage fees, demurrage charges, and supply chain disruption.
Common Scenarios for Detained Shipments
Ocean Freight Containers Under Examination
CBP may select full container load (FCL) shipments for intensive inspection or documentation review.
Air Freight With Documentation Errors
Time-sensitive shipments can face severe delays if entry documentation is inaccurate.
