<h1>Express cargo clearance integration: retain ECCS features within a modular, API-enabled customs system to ensure swift facilitation.</h1> Integration of the Express Cargo Clearance System (ECCS) into the Customs Integrated System (CIS) must preserve ECCS's distinctive features by creating a dedicated, API-enabled express clearance module within a modular CIS architecture. Core ECCS functionalities-real-time status updates, bulk filing, and bulk/auto OOC/LEO-should be retained and ICEGATE capabilities assimilated to reduce redundancies and dwell times. System-driven examination, a refined risk management framework balancing facilitation and control, a dedicated express help desk, limited scheduled downtimes, continuous industry engagement, and auto-linking of government-held data are required to ensure agility, scalability, and interoperability.
