    Professional auto transport carrier delivering vehicles cross-country safely.

    For international maritime trade and high-risk domestic logistics, standard plastic sealsare simply not enough. High-security bolt and barrier seals provide the physical resistance needed to protect high-value automotive cargo from professional theft.

    ISO 17712:2013 Standards

    To be classified as "High Security," a bolt seal must meet the ISO 17712standard. This involves rigorous testing for tensile, shear, bending, and impact strength.

    Anti-Spin Technology

    Modern high-security bolts feature "anti-spin" technology. This prevents a thief from spinning the bolt inside the locking chamber to unscrew or bypass it without breaking the core.

    Barrier Seals: The Ultimate Deterrent

    Barrier seals take security a step further by physically blocking the locking rods of a container or trailer. They are often made of heavy-duty steel and requires power tools to remove.

    Key Features of Barrier Seals

    Heavy-duty steel construction resistant to standard bolt cutters
    Dual-locking mechanisms for redundant security
    Serialized laser etching for permanent identification
    Visual indicator for immediate tampering detection

    Auto Transport Applications

    We utilize these high-security options primarily for two scenarios in our vehicle logistics network:

    Long-term StorageBarrier SealMaximum

    Expert Tip

    Bolt seals should always be removed using heavy-duty bolt cutters (at least 24 inches). Attempting to remove them with standard pliers can damage the container hardware.

    Conclusion

    When it comes to your vehicle investment, there is no such thing as too much security. Using ISO-compliant bolt and barrier seals ensures that your asset arrives exactly in the same state it was loaded.

    Q.What is the ISO 17712 standard for bolt seals?

    ISO 17712:2013 classifies bolt seals as High Security based on rigorous testing for tensile, shear, bending, and impact strength. Only seals that pass all tests earn this classification.

    Q.What is a barrier seal and when is it used?
