Certified Cable Seals in Modern Industrial Applications

ISO 17712:2013 ("Freight containers — Mechanical seals") is the globally recognized international standard governing the testing and classification of mechanical seals used to secure freight containers, trailers, trucks, and other cargo transport units. Cable seals, a prevalent type utilizing a flexible steel cable threaded through a locking mechanism, fall squarely within the scope of this standard. 

ISO 17712 Certification: Mandatory for international shipping, these seals undergo brutal testing (＞975kg pull force, shear resistance, -27°C impact tests) to prevent cargo tampering. Logistics companies using ISO 17712 certified container cable seals report 30% fewer customs inspections.

Tamper-Evidence: To provide clear, irreversible visual or physical evidence if a seal has been attacked or removed without authorization.

Deterrence: To present a significant physical barrier to unauthorized access.

Standardization: To establish uniform, internationally accepted criteria for seal strength and security performance.

Supply Chain Integrity: To enhance security throughout the global supply chain, combating theft, pilferage and contamination.

"H" (High Security):3.5mm-5.0 mm

Requirement: Highest level of resistance to deliberate, covert intrusion attempts using sophisticated tools and techniques within a defined time period (e.g., bolt cutters, saws, pry tools).

"S" (Security):1.0mm-3.0mm

Requirement: Provides a significant level of tamper resistance against opportunistic attacks using more readily available tools.
