Definition & Explanation
A freight forwarder takes over a tank container after a long sea voyage—and finds the seal broken. Mechanical seals for tank containers are physical locking devices fitted to a container's closure points to make unauthorized access immediately visible and verifiable. Available in single-use or reusable designs, they are applied before departure and checked upon arrival. A broken or missing seal triggers consequences in customs clearance and supports—or complicates—insurance claims. ISO 17712 sets the international standard for mechanical strength and security features, distinguishing between high-security seals and lower-rated alternatives. For hazardous goods and food-grade shipments, regulatory frameworks frequently mandate their use.
