Understanding Security Seals

Security seals are tamper-evident devices designed to secure and protect valuable assets during transportation and storage. They provide a clear indication of any unauthorized access or tampering, making them essential tools for supply chain security, asset protection, and regulatory compliance.

Why Use Security Seals?

• Tamper Evidence: Immediate visual indication of unauthorized access
• Theft Deterrence: Psychological barrier against theft and pilferage
• Chain of Custody: Track and document asset movements
• Regulatory Compliance: Meet industry and customs requirements
• Brand Protection: Protect product integrity and brand reputation

Industries Using Security Seals

Transportation & Logistics

Shipping companies, freight forwarders, and logistics providers use security seals to protect cargo containers and shipments. ISO 17712 compliant seals are required for international shipping and customs clearance.

Banking & Financial Services

Banks and cash management companies use security seals for ATM cassettes, cash bags, and valuable document transportation. These seals help maintain audit trails and prevent internal theft.

Retail & E-commerce

Retailers use security seals for inventory management, warehouse security, and protecting shipments. E-commerce companies rely on seals to ensure products reach customers without tampering.

Healthcare & Pharmaceuticals

Medical facilities and pharmaceutical companies use security seals to protect medications, medical equipment, and sensitive patient information during storage and transportation.

Utilities & Energy

Utility companies use security seals on meters, equipment panels, and storage facilities to prevent tampering, theft, and unauthorized access to critical infrastructure.

Choosing the Right Security Seal

Consider Your Application

Different applications require different seal types:

• High-Security Applications: Heavy-duty metal seals or cable seals
• General Cargo: Pull-tight plastic seals
• Bags & Boxes: Fixed length seals
• Utility Meters: Specialized meter seals

Security Level Requirements

Match the seal strength to your security needs. High-value cargo requires high-security seals that meet ISO 17712 standards, while lower-value items may be adequately protected with indicative or barrier seals.

Environmental Conditions

Consider temperature extremes, UV exposure, chemical exposure, and weather conditions. Choose seals made from materials that can withstand your specific environmental challenges.

Best Practices for Seal Usage

• Inspect seals before use to ensure they are not damaged or defective
• Always record seal numbers before application for tracking purposes
• Apply seals correctly according to manufacturer instructions
• Store unused seals in a secure location with controlled access
• Train personnel on proper seal selection, application, and inspection
• Establish clear procedures for reporting missing or tampered seals
• Regularly audit seal inventory and usage
• Document seal applications and removals in your records
• Replace seals immediately if removed, even for authorized inspections

Frequently Asked Questions

Can security seals be reused?

No. Security seals are designed for single use only. Once applied and locked, they cannot be removed without visible damage, ensuring tamper-evidence.

What is ISO 17712?

ISO 17712 is an international standard for mechanical freight container seals. It specifies requirements for high-security seals used in international shipping and customs applications.

How do I track seals?

Each seal has a unique identification number. Record this number before application and at each custody transfer point. Many organizations use barcode scanning systems for efficient seal tracking.

What if a seal is found broken?

A broken or missing seal indicates potential tampering. Follow your security protocols, which typically include thorough inspection, incident reporting, and investigation before proceeding.
