Accountability and operational efficiency are key factors in the risk mitigation strategy of our customers.
It is our priority to supply you with the appropriate tamper evident security seal for each of your specific applications.
Have a good understanding of the strength the seal must withstand as a risk mitigation enabler to serve its purpose. This will determine whether you need a plastic, cable or bolt seal.
For example, if it is high value goods you want to transport, a cable seal may be a better option than a plastic tamper evident security seal. If you use rolltainers, it may not need a bolt seal and if it is a container a plastic seal may not be the ideal solution.
Let us know the diameter of the hole the tamper evident security seal must go through or wrap around. That will give us an opportunity to propose the correct seal for your application and technical specifications.
Regardless of the volume of tamper evident security seals you require, we can help.
Is it important to have your seals personalised? And do you require a specific colour?
Inventory control and ensuring product integrity is key elements to ensure customer trust. Risk mitigation enablers such as tamper evident security seals, tamper evident tape or tamper evident labels are used as serialized trackers of products in the warehouse.
Tracking products with tamper evident security seals as part of an inventory control system is key to prevent stock shortages. Customer orders are filled timeously as tamper evident security seals prevent stock shortages.
Tracking products also prevent trapped cash in over stocked products in the warehouse. Tamper evident seals are also used as visual proof of tampering during storage of products in the warehouse.

ISO17712:2013 “H” Class
ISO 17712 is an international standard that specifies the requirements for mechanical freight container seals used in international shipping — especially to ensure they are tamper-evident and secure.
Here’s the breakdown:
Purpose: To protect cargo containers from unauthorized access and indicate if tampering has occurred during transit.
Scope: Applies mainly to high-security seals such as bolt seals, cable seals, and other mechanical seals used on intermodal containers.
Key Requirements:
Seal strength — physical performance requirements so they can’t be easily broken.
Tamper evidence — seals must show clear, irreversible signs if someone tries to remove or replace them.
Testing & certification — seals must pass tests conducted by accredited labs.
Seal marking — must have a unique identification number.
Manufacturer security — controls on seal production to prevent unauthorized duplication.
Categories under ISO 17712:
Indicative seals (low strength, for evidence only)
Security seals (medium strength)
High-security seals (H) — the only type recognized for compliance with U.S. Customs–Trade Partnership Against Terrorism (C-TPAT) and the World Customs Organization’s SAFE Framework.
In short, ISO 17712 seals are the gold standard for shipping container security — if you see “ISO 17712: High Security” on a seal, it means it’s been tested and certified to resist tampering and forced entry.
Here’s a comparison table of ISO 17712:2010 vs ISO 17712:2013 to clearly highlight the key differences:
| Category | ISO 17712:2010 | ISO 17712:2013 |
| Seal Classifications | Defined three classes: Indicative, Security, High-Security | Same three classes; reinforced criteria for High-Security |
| High-Security Seal Testing | Required mechanical testing to meet certain thresholds | Testing methods clarified and aligned more with international standards |
| Tamper Evidence | Required seals to show evidence of tampering | More detailed and specific requirements for visible, irreversible tamper evidence |
| Tamper Evidence Testing | General expectations | Clear test procedures introduced to verify tamper-evidence functionality |
| Manufacturer Security Practices | Mentioned but not detailed | Mandatory compliance with security-related best practices during production, storage, and distribution |
| Certification Requirements | Less detailed regarding testing documentation | Clearly defined documentation and audit expectations for certification bodies |
| Counterfeit Protection | Not directly addressed | Stronger emphasis on preventing unauthorized duplication or counterfeiting of seals |
| Seal Marking Requirements | Included basic requirements | No major changes, but more closely monitored under clarified testing regimes |
| Compliance with C-TPAT | Accepted if seals met High-Security classification | Still compliant, but only seals tested per 2013 standards qualify as “High-Security” for C-TPAT |
Here’s what changed:
Tamper evidence requirements clarified
Testing requirements refined
Manufacturer security practices strengthened
Confirmation of high-security seal classification
Yes, if you fancy a personal touch with your own corporate image and identity, you can personalize your tamper evident security seals. You can get them printed with your company name and logo or you can order them in the color of your choice.
Laser marking is a tamper evident printing method that cannot be imitated or changed. A laser beam cuts into and permanently marks the tamper evident security seals. This printing technology enables the tamper evident security seals to withstand harsh environmental conditions. Laser marking is a tamper evident enabler and ideal for the chemical, pharmaceutical and food industries.
Let’s be honest, nothing in South Africa is tamper proof. Tamper evident security seals are exactly what their name implies, they are tamper evident not tamper proof. A tamper evident security seal is an indicative seal, constructed and manufactured of e.g. plastic that can easily be broken or cut by using a simple snipping tool like scissors. Tamper evident security seals are manufactured with built in tamper evident features to leave evidence of tampering. The purpose of a tamper evident security seal as part of a security management system, is to enable you to mitigate and manage the risks associated with tampering like theft. Tamper evident security seals are by no means designed to tamper proof your cargo.

Tamper evident seals date back to ancient times. Tamper evident security seals were initially made from wax and clay. They were used to protect valuables and verify authenticity. Today, tamper evident security seals are made from plastic and other materials. It consists of a flag or flap and a tail. Printing or marking can be done on both the flag and the tail.
1. High security seals like cable seals or bolt seals
2. Security seals which provide limited resistance to intrusion like a plastic seal with a metal insert and
3. Indicative seals manufactured of a material that can easily be broken like a single molded plastic seal with no metal insert

Yes, the tensile strength or breaking point indicates the seal’s ability to withstand stress or pressure before it breaks, for example if you use a tamper evident security seal to seal a cage and there is a lot of pressure placed on the door of the cage by the boxes in the cage, you need to choose a seal with a higher tensile strength or breaking point to withstand the pressure the boxes place on the cage’s door.
It is the point at which the material of a tamper evident security seal breaks or snaps when pulled apart in a machine called a tensile tester. A tensile tester determines the mechanical properties of a material and is normally used in material testing labs.
Tracing and tracking cases of tampering and theft in operation. Keep a record or register of the serial numbers printed on the seals you receive and issue in operation. It enables you to trace, track and investigate cases of tampering and theft throughout your supply chain.
