Press Title: Upgraded Aluminum Alloy Steel Wire Seal Launched: Achieves ISO 17712 High-Security Certification, Enhances Cargo Safety in Extreme Environments
As global trade and logistics transportation continue to demand higher levels of cargo security, anti-counterfeiting traceability, and management efficiency, a new type of aluminum alloy steel wire seal (commonly known as a tamper-evident seal or bolt seal) is gradually replacing traditional plastic seals. It is gaining widespread application across customs, container shipping, tanker trucks, railway freight, and other sectors.
This product is a single-use locking device (keyless lock), specifically designed for anti-counterfeiting and transportation security. Compared to ordinary plastic seals, the aluminum alloy steel wire seal achieves multiple technical upgrades in structural strength, environmental adaptability, and information management.
Technical Field
The aluminum alloy steel wire seal, collectively known as a tamper-evident seal or a single-use lock (keyless lock), is designed for anti-counterfeiting and security across various industries. Through the development and upgrade of the aluminum alloy steel wire seal, advancements have been made in material-based anti-counterfeiting, including the printing of barcodes, QR codes, serial numbers, and company names. This ensures unique security under non-destructive conditions and supports data collection and verification during management processes. At the same time, the product achieves comprehensive upgrades in tensile strength and aesthetic functionality compared to traditional seals.
Key Technologies
1. Structural Upgrade: Utilizes an aluminum alloy housing and steel wire, combined with an internal self-locking mechanism, significantly enhancing the tensile strength of previous plastic seals.
2. Enhanced Environmental Adaptability: The aluminum alloy housing is treated with oxidation coloring and logo printing, making it suitable for extreme environments like severe cold and high heat, while also improving the recognition rate of barcodes and QR codes.
Technical Specifications
* Tensile Strength Range: 100 kg to 1000 kg
* Steel Wire Diameter: 0.8 mm to 8.0 mm (customizable)
* Length Range: 100 mm to 2000 mm (customizable)
* Operating Environment: Stable operation in temperatures ranging from -40°C to +40°C, with good alkali resistance
ISO 17712 High-Security Certificate Description
This product has passed ISO 17712:2013 international standard certification, meeting the technical requirements for high-security seals.
What is ISO 17712?
ISO 17712 is a unified standard established by the International Organization for Standardization (ISO) for the classification, certification, and acceptance of mechanical seals for freight containers. This standard provides a single source of information for mechanical seals used to secure freight containers in international trade, ensuring products are safe, reliable, and of good quality.
Certification Level Classification
The ISO 17712 standard defines three levels (classes) of seal strength:
| Level | Name | Description |
|---|---|---|
| "H" Level | High Security Seal | The highest security level, capable of resisting forceful entry attempts with tools. Requires testing by an independent third-party laboratory. C-TPAT (Customs-Trade Partnership Against Terrorism) mandates the use of "H" level seals for international container shipments. |
| "S" Level | Security Seal | Offers strength higher than indicative seals but does not meet the high-security level. Suitable for low-risk or domestic transportation. |
| "I" Level | Indicative Seal | Primarily provides evidence of opening rather than mechanical resistance. Suitable for internal transfers, mail bags, etc. |
How to Verify ISO 17712 Certification
To ensure the seals being procured are genuine high-security "H" level products, it is recommended to request and verify the following documents from the supplier:
* ISO 9001 Certificate (Manufacturer's Quality Management System certification)
* ISO 17712:2013 Annex A Certificate (Best practice process certification)
* ISO 17712:2013 Clause 5 "H" Level Laboratory Test Report/Certificate (Issued by an ISO 17025 accredited laboratory)
* ISO 17712:2013 Clause 6 Tamper Evidence Compliance Proof
Product Certification Marking
Seals that obtain ISO 17712 "H" level certification will have the following information permanently marked on the lock body:
* "H" Marking: Indicates high-security level
* Unique Serial Number: Laser etched to ensure traceability and prevent reuse
* Manufacturer Identification / LOGO
Market Advantages
This product holds a significant market position in the seal industry due to its outstanding advantages, including ease of use and low cost. The aluminum alloy steel wire seal is suitable for customs transportation, containers, container trucks, tanker trucks, railway freight boxes, and other areas, effectively enhancing the security and management verification efficiency of enterprise cargo transportation.
Technical Performance Advantages
1. Non-Tamperable: Once applied, the seal cannot be opened, removed, delivered, dispatched, swapped, modified, mortgaged, pledged,留置, repurposed, have its markings changed, or be used for any other purpose, ensuring full-process security and control.
2. Outstanding Environmental Adaptability: Particularly suitable for demanding applications like ocean container shipping that require high tensile strength and alkali resistance, while also meeting operational needs in high and low-temperature environments.
