Frequently Asked Questions

We understand you might have questions about selecting and using the right seal for your needs. Below are answers to some of the most common enquiries, designed to help you make informed decisions.

Q1. What are Security Seals, and why are they essential? 

Security seals are tamper-evident devices that visibly indicate if cargo, assets, or containers have been accessed without authorisation. They're crucial for deterring theft, ensuring product integrity, providing traceability via unique numbering, and meeting compliance requirements for various industries like transport and logistics.

Q2. What types of Security Seals does Universeal offer? 

Universeal UK offers a comprehensive range of high-quality security seals. These include indicative seals like plastic pull-through, fixed-length, and metal strip seals for visual tamper detection on items like tote boxes or cash bags. We also provide robust ISO 17712 compliant high-security barrier seals, such as bolt and cable seals, essential for securing shipping containers, trucks, and trailers in international trade. See our full guide to the types of security seals for more information.

Q3. How do I choose the right Security Seal for my application? 

Consider the level of security needed (basic indicative use vs. strong physical barrier), the application environment, desired break strength (from easy-break 5KgF to 2000KgF+ barrier seals), and the seal's usable length and tail diameter. Also, determine your customisation needs for numbering, barcodes, or logos. We have put together a helpful guide on choosing the best security seal for the job, and our team can help you select the ideal solution. 

Q4. What is ISO17712, and why is it important? 

ISO 17712 is an international standard classifying and testing mechanical freight container seals for strength and tamper-evidence. It categorises seals (Indicative, Security, High Security) and sets rigorous performance tests. High-Security (H) seals are often mandated for international shipping by customs (e.g., C-TPAT). Our ISO 17712 compliant seals undergo independent testing for certified reliability.

Q5. How 

do I know if a Seal has been tampered with?

A tamper-evident security seal shows clear signs of interference. Look for physical damage (breaks, cuts, unusual marks), altered numbering or barcodes, "blushing" or stress marks on plastic, or any signs of replacement. For cable seals, frayed internal wires indicate cutting. Regular inspection and matching serial numbers against records are key to detection.

Q6. Do you offer customisation?

Yes, most of our security seals can be customised. We can add unique sequential numbering, barcodes, QR codes, and your company logos or text. Customisation enhances security by making seals harder to replicate and improves traceability and brand recognition.
