What is the typical duration for which CBP detains shipments?

The typical duration for which Customs and Border Protection (CBP) detains shipments is commonly established at 30 days. This timeframe allows CBP to thoroughly assess shipments for compliance with regulations, ensuring they adhere to import policies and do not pose any risks, such as safety concerns or violations of intellectual property rights. The 30-day period provides a balance between giving enough time for inspections and legal processes while also promoting efficiency in trade and commerce.

In the context of this question, while options representing shorter and longer durations may seem plausible, they do not reflect the standardized practices that CBP follows in managing and processing detained shipments. The 30-day duration aligns with procedural guidelines and operational standards that govern the agency's handling of international shipments.
