Barrier Seals
Barrier seals provide the maximum protection for shipping cargo via trucks and containers. Installed on the locking rods of the shipping container doors to secure both doors, they are easy to install and require no special tools. Most of the barrier seals featured on this page are a one-time use product.
Our CargoShield™ product line are our best barrier seals (BAR10, BAR11, BAR12); they have been independently tested and certified to ISO 17712:2013 as a high security seal. They resist physical attack from saws, cutting sheers, bolt cutters, levering by crowbar, impact by hammer, etc. To remove the seal use a electric cutting wheel, which normally takes about 2 minutes in field conditions.
Our most affordable barrier seal is our DualGuard™ product, which is a combination bolt and cable seal. The DualGuard™ also has been independently certified to meet ISO 17712:2013 as a high security seal. The seal is removed using bolt cutter.
Our MS-BAR9 is a reusable barrier seal. The recommended locking method is a bolt seal (purchased separately), but it is also compatible with a padlock you supply.
For added security, all of our barrier seals have matching serial numbers on key components.
Choosing A Barrier Seal
ISO-rated barrier seals are independently tested to meet structural performance standards to earn the "HIGH" security rating. CTPAT recommends HIGH security seal for cross border shipments.
Ask prospective suppliers of your barrier seals to provide the manufacturer’s written verification the seal was independently tested to comply with ISO 17712:2013 as a HIGH security seal. To meet the ISO standard, the testing and certificate must be dated within 24 months of your purchase.
Confirm the manufacturer’s name molded in the barrier seal matches the certification.
Seals that fit wider spacing on the locking rods will be compatible with more containers and trucks. Sometimes the locking rods on rail cars and ocean containers have wider spacing than truck trailers.
Matching serial numbers on all the major seal components offer more security. Engraved numbers are more durable.
Thicker and wider steel (higher cross sectional area) offers more security because it takes longer and is more difficult to remove. Some competitive products tout hardened steel construction, which offers some added resistance for hack saws, but offers no added resistance to cutting wheels.
A companion latching cable secures the barrier seal to the door latch to minimize tampering with the seal and locking rods on the door. Also, this configuration requires two cuts to remove both the barrier seal and the latching cable, which improves security.
Seals with bar codes of the serial number offer improve productivity in recording the serial number.
Seals packaged in individual boxes are easier and less cost to distribute in small quantities.
For the best security, we recommend our CargoShield™ products with latching cable (MS-BAR11, MS-BAR12).
The MS-BAR9 is locked with a bolt seal or padlock, so the barrier seal componets are reusable.
As a lower cost option, we also offer a bolt/cable combination (called DualGuard™). Both the bolt and cable are ISO-rated to ISO17712:2013 as a HIGH security seal, as required by CTPAT. It requires two cuts (using a bolt cutter) to remove the DualGuard™.

Other Security Options
Layering security improves security. Although barrier seals offer exceptional security, for the highest security, use more than one sealing method.
Sometimes barrier bar seals are provided without any companion seals to secure the door latch. If no companion seal (or latching cable) is provided, using an optional bolt or cable seal to secure the latch will improve security.
Some barrier seals are available with latching cables (which have matching serial numbers) to also secure the barrier seal to the door latch. This configuration reduces tampering of the locking rods and barrier seal. MS-BAR11 is a barrier seal with a companion latching cable — both the barrier seal and cable are ISO-rated.
For high security applications, barrier seals can also be combined with cargo door Seals, which are large tamper evident labels to prevent the removal or opening of the container doors. When removed, the Cargo Door Seals will self "VOID" to indicate tampering.
Our most affordable barrier seal is a bolt/cable combination (called DualGuard™). Both the bolt and cable are ISO-rated to ISO17712:2013 as a HIGH security seal, as required by CTPAT.
