Barrier Seals

Product Overview

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.

Reusable Barrier Seal, MS-BAR9

While Supplies Last

Barrier Cargo Seal

CTPAT and ISO 17712:2013 Compliant High (H) Security Seal

CTPAT Compliant

We also offer a reusable barrier seal which consists of the locking bar and two floating shackles.

The locking bar has an 11mm ID hole (7/16 inch) to accommodate a bolt seal or padlock.

The recommended method to lock the MS-BAR9 is using our MS-B8 bolt seals (sold separately). Although the bolt seal is a one-time use seal, the barrier seal components are reusable.

The MS-BAR9 also includes these added features:

  • Matching serial numbers on all 3 components for added security
  • Constructed of thicker steel for added durability and security
  • Unpainted metal components highlight tampering
  • Accommodates more container doors (up to 17.25 inch spacing of locking rods)
  • Easy to install (typically less than 15 seconds)

The MS-BAR9 is constructed of the same components as our ISO-certified barrier seals (BAR10 and BAR11). However, MS-BAR9 has not been ISO-tested and does not have the ISO-certification at this time.

Each seal is packaged individually in a box suitable for shipping, which simplifies the logistics of distributing individual seals.

Full cases include 6 seals — each seal is packaged in an individual box.

Installation Instructions

MS-BAR9 Installation Guide

The recommended method to seal the MS-BAR9 is using our MS-B8 bolt seal (purchased separately) inserted into the hole of the bar. In this configuration, the bolt seal is a one-time use item (removed by cutting with a bolt cutter), but the MS-BAR9 barrier seal components are re-usable.

Another option, though less secure, is to use a padlock. Although we don't recommend any specific padlock, the MS-BAR9 is compatible with any padlock which meets these dimensional clearances:

  • Maximum Shackle Diameter: 11mm (7/16 inch)
  • Minimum Throat Clearance (when locked): 12mm (1/2 inch)

In October 2014, we reviewed these padlocks to confirm the dimensional clearances (you can decide if these padlocks meet your security and budget requirements):

  • MasterLock 187XD
  • MasterLock 187XKAD
  • MasterLock 6270/970

We only evaluated a few locks for fit. There are many other brands of padlocks which are dimensionally compatible.

The lock companies offer padlocks keyed the same or keyed differently.

For added security, consider a keyed padlock which includes these features:

  • The key cannot be removed when the lock is open.
  • The shackle is shrouded (added protection against abuse)

However, the security risks for padlocks include:

  • Control of the keys
  • The possibility of picking the lock

For added protection against these risks, the key hole can be protected with a tamper evident label with a serial number. Please see our wide selection of residue or non-residue security labels to fit your padlock.

Combination padlocks are another option for locking the MS-BAR9
