Container Security Devices protect cargo against theft, tampering, and unauthorized access throughout the supply chain—a requirement driven equally by customs regulations and cargo insurance conditions. They encompass mechanical and electronic systems such as high-security seals, locks, and sensors fitted to container doors or fittings, making any unauthorized opening immediately visible or electronically logged. Certified high-security seals must conform to ISO 17712; their use is mandatory for specific cargo categories and certain customs procedures. Customs authorities and terminal operators inspect seals and locks during import and export processing—a broken or missing device routinely triggers a physical customs examination, causing delays and additional costs.
