Container security seals play an important role in maintaining chain-of-custody throughout international transportation.
For shipping lines, freight forwarders, customs brokers and security seal distributors, the objective is not to make containers impossible to open. The objective is to provide clear, verifiable evidence if unauthorized access occurs during transit.
Our container seals are manufactured for applications where customs compliance, serialization accuracy and reliable tamper indication are critical to daily operations.
Security Seal Solutions for Different Risk Levels
ISO 17712 High Security Bolt Seals
Designed for container doors used in international freight movements where customs authorities require high-security seals.
Features include:
Hardened steel locking components
Anti-spin locking mechanisms on selected models
Permanent laser serialization
Single-use destructive locking design
Available with:
Sequential numbering
Company logos
Barcodes
QR codes
Applications:
Ocean freight containers
International trailers
Rail freight equipment
Adjustable Cable Seals
Suitable where locking points vary in size or where fixed-length bolt seals cannot be installed.
Typical applications include:
Tank containers
Tanker trucks
Valves
Intermediate bulk containers
Intermodal transport equipment
Available cable diameters:
1.5 mm
2.5 mm
3.5 mm
5.0 mm
Non-preformed cable construction causes strands to separate after cutting, making unauthorized reassembly more difficult and easier to identify during inspection.
Indicative Plastic and Metal Seals
Designed for lower-risk applications requiring visual tamper indication rather than physical resistance.
Typical applications:
Airline catering carts
Tote boxes
Retail distribution
Empty container return programs
Serialization and Traceability
Laser engraving removes material from the seal surface rather than applying ink, reducing the risk of identification loss caused by abrasion, moisture or sunlight exposure.
Every seal can be permanently marked with unique identification data including:
Consecutive serial numbers
Company names
Logos
Barcodes
QR codes
This supports:
Customs documentation
Shipment verification
Internal audits
Insurance investigations
Chain-of-custody records
Manufacturing Controls
Consistency is particularly important for distributors handling large annual volumes.
Production controls include:
Incoming raw material inspection
Locking force verification
Serialization checks
Visual inspection
Random sampling tests
Supporting documentation can include:
ISO 17712 reports
Material certificates
Inspection records
Depending on product type and customer requirements.
