Prevent collusion and create a reliable chain of custody across the value chain

COMMON APPLICATIONS: Truck doors, sacks, rolltainers, boxes, containers, pallets, warehouse doors, storage cages, tote bins, drums, crates

From chemicals to perishables, multiple hands in a supply chain imply risk. Uniquely numbered seals are used for tracking shipments, as the unique numbers can be linked to a specific shipment and tracked throughout the entire shipping process. In addition, security seals provide tangible evidence of tampering should an investigation be necessary. Security seals provide peace of mind that a shipment will remain securely protected along its journey. Seals also play a key role in the damages and claims process. If the seal's integrity has been compromised, and records have been kept verifying the seal's number at different stages of the value chain, it is easier to identify the point of liability. Goods in transit and goods in storage are better managed with security seals. For cross border movements, Cambridge has the solution - a wide range of products which meet the technical requirements of C-TPAT. Click here for more information.
