U.S. Customs & Border Protection

The U.S. Customs and Border Protection (CBP) operates dynamically within the broader Bay Area maritime and aviation sectors to secure federal entry borders, enforce trade regulations, and facilitate legal international commerce. Managing its critical regional operations primarily out of the Port of San Francisco and Oakland International Airport, the federal agency inspects arriving cargo vessels, container shipments, and international passengers. Their targeted regional presence ensures strict compliance with customs, agriculture, and immigration laws, providing the essential security infrastructure required to protect domestic industries while maintaining fluid supply chains across Northern California trade corridors.
