Cable seals are high-security tamper-evident fastening solutions manufactured from durable steel cable combined with aluminum alloy locking heads. Featuring a one-time irreversible locking design, they effectively prevent unauthorized opening, tampering, and accidental loosening during transportation and storage. Widely used in logistics, shipping, utilities, and industrial sectors, these seals provide reliable asset protection and strong anti-theft performance in demanding environments.
Our cable seals comply with major international certifications, including ISO 17712:2014 standards for high-security freight seals, C-TPAT compliance for North American cross-border shipments, ISO 9001 quality management certification, and RoHS environmental standards. These certifications ensure global acceptance by customs authorities, port operators, and logistics providers, helping to avoid clearance delays and maintain smooth supply chain operations.
Designed for efficient field use, the seals feature a tool-free self-locking mechanism. The steel cable is inserted into the locking body, where an internal ratchet automatically engages, ensuring a secure and irreversible lock. One-hand operation improves efficiency in warehouses and ports, while removal requires professional cutting tools, leaving clear visible evidence of tampering.
These cable seals are widely applied in container shipping, rail freight, trucking, tanker transport, air cargo, courier services, banking security, utility metering, bonded warehouses, and high-value cargo protection. OEM/ODM customization is available, including cable size, material, locking design, and marking options.
