Supporting secure container movements with robust, compliant security seal solutions.
Global shipping relies on trust, traceability, and security. With millions of containers moving through ports, vessels, and distribution hubs every year, protecting cargo from theft, tampering, and contamination is a critical challenge. For shipping lines, freight forwarders, exporters, and importers alike, security seals play a vital role in maintaining supply chain integrity.
At Mega Fortris UK, we provide a wide range of high-quality security seals designed specifically for the demands of the shipping and container industry, helping businesses protect goods from origin to destination.
Why Security Seals Are Essential in Container Transport
While shipping containers are designed to protect goods from environmental damage, they do not prevent unauthorised access on their own. Containers may be opened during transit without immediate detection, particularly at busy ports or inland hubs. A properly fitted security seal provides a clear visual indication if access has occurred.
In practical terms, security seals help to:
- Provide visible tamper evidence
- Act as a deterrent against opportunistic theft
- Create an audit trail through unique seal numbering
- Support compliance with customs and security programmes
These benefits make seals a critical component of container security from origin to destination.
The Role of ISO 17712 Security Seals
For shipping containers used in international trade, ISO 17712-compliant security seals are widely recognised as the industry standard. These seals are independently tested for strength, durability, and tamper resistance, making them suitable for customs and border security requirements worldwide.
Mega Fortris UK supplies high-security bolt seals & cable seals that meet ISO 17712 standards, offering confidence to shipping operators and customs authorities alike. These seals are designed to withstand harsh marine environments while providing clear visual evidence if tampering has occurred.
Security Seal Types Used in the Shipping & Container Industry
Different shipping applications require different levels of security. Mega Fortris UK offers a comprehensive range of seal types to suit containerised cargo at every stage of the supply chain.
High-Security Bolt Seals
Bolt seals remain one of the most commonly used security seals for shipping containers. Consisting of a hardened steel bolt and locking barrel, they are designed for single use and must be broken for removal, making any interference immediately visible during inspection.
Bolt seals are commonly used for:
- ISO shipping containers
- Road trailers
- Rail freight and intermodal transport
Their strength, reliability and clear numbering make bolt seals a trusted option for operators seeking a high level of security without adding complexity to inspection procedures.
Cable Seals
Cable seals are valued in the shipping and container industry for their versatility. Their adjustable steel cable allows them to be used on a wide range of locking points, including non-standard or irregular fittings. This flexibility makes cable seals particularly useful where containers or transport equipment vary.
Cable seals are commonly used for:
- Tank containers and bulk liquid transport
- Rail wagons and freight cars
- Containers with non-standard locking points
- Multi-door or multi-access shipments
They are available in different cable diameters and security levels, allowing operators to select the appropriate balance between strength, flexibility and regulatory compliance.
Plastic Indicative Seals
Not every shipment requires a high security solution. For lower-risk cargo, domestic movements or internal logistics, plastic indicative seals are often sufficient. These seals are not designed to resist force but provide clear visual evidence if unauthorised access has occurred.
Plastic security seals are commonly used in:
- Domestic shipping and distribution
- Retail and FMCG supply chains
- Warehousing and storage environments
They also offer practical advantages such as colour coding, custom numbering, and cost efficiency, making them a popular choice for many logistics and distribution operations.
