Container seal

One tool that is often used in supply chain security planning is security seals.There are two main types of container seals: indicative and isolation.

An indicative seal indicates whether the sealed item has been tampered with.They are easy to break because their function is to demonstrate input, not to block it.

The use of stronger seals (called isolation seals) is becoming more and more common.In addition to providing evidence of tampering, these seals prevent theft because they are difficult to remove.

These shipping container seals are commonly used in shipping containers, trams and long-distance trucks.

Select shipping container seals

The following criteria determine the best seal for your application:

  • Determine if indicative or barrier seals are required.
  • If an isolation seal is used, determine the required strength level.
  • Make sure the seal type you choose is suitable for the device.
  • Select seals of appropriate strength and safety.
  • Measure seal cost and safety risk.
  • Consider the tools and resources at your disposal and use an easy-to-manage locking system.
  • Consider the durability of seals relative to their environment.

Effective use of safety seals

The transport container security seals themselves are not effective procedures for supply chain security and product tracking.

It is a component that, when used effectively and in combination with other security measures, can provide evidence of tampering and even help prevent theft.

However, other steps can be taken to enhance its effectiveness.

  • Layered devices, using multiple seals, matching labels and tapes, or by separating the seals from the bar code to impose isolation seals.
  • Rotation using alphanumeric combinations of various sizes, styles, colors and security seals may make tampering more difficult.
  • Logos, custom tags, warning labels, or any other type of symbol can quickly and easily identify the source and content, helping to prevent tampering

If you are in the dangerous goods business, you may use a security seal somewhere.Maybe a lot of places.But you may not realize that DG professionals work in sealed ways and locations.

Guidelines for compliance with C-TPAT sealing requirements

The Customs Counter-terrorism Trading Partnership (C-TPAT) is a joint effort between the government and commercial shippers to develop a comprehensive cargo security plan for goods imported into the United States.

The voluntary scheme, which aims to protect global commerce from the effects of terrorism, applies primarily to the transport of goods by any shipper or carrier using intermodal containers and truck trailers.

It is important to know about c-TPAT seals.The primary requirement of C-TPAT is the use of high security seals on goods entering the United States.

The program stipulates that these high-security seals must pass the highest strength test of ISO/PAS-17712.The physical properties of seal strength are summarized by iso.

It defines three levels according to impact, shear, bending and tensile strength: indicative, safe and highly safe.

Indicative seal

All light weight strips that can be removed by hand or with a regular household paper cutter

Security seals

Medium strength seals require strong tools and more force to open

High security seal

The strongest and hardest sealing strip to cut.It takes a professional, industry-powerful tool to cut them open.Performing such tests requires resistance to high levels of tension, bending and extrusion.

The best way for commercial shippers to ensure compliance with C-TPAT is to keep abreast of the situation, develop a detailed product tracking plan for the supply chain to prevent theft, and ensure seals are as strong and effective as possible.Strategies to prevent seals from being tampered with and improve the safety of cargo seals include:

  • Use multiple seal or layering techniques
  • Match labels and tapes for enhanced visual recognition
  • Seal isolation by separating the seal from the bar code
  • Enable an RFID tag or other unique identifier
  • Take turns using color and alphanumeric combinations
  • Use safety seals of all sizes, sizes and styles
  • Attach warning labels to packages and sealing points for employees
  • Adds a unique marker or indicator when locking

Are you missing critical security measures?

Here are 11 places where seals are not only useful, but essential.Closures that can only be opened once provide more protection than you might think.The lock can be re-locked, but a broken seal can definitely tell you that the container or container has been opened.

Eleven places

Cargo container.Okay, that’s pretty obvious.For national security (not to mention general safety and theft prevention), you need to use c-TPAT compliant high-security seals on most intermodal containers and truck trailers used to transport dangerous goods.

Cargo doors and gates.Of course, you can keep them locked, but locks have keys.To adequately prevent theft and tampering, consider using heavy wire cable seals when storing valuable materials.Security is not “as tight as a drum” unless you don’t know that a photosensitive drum is not on.Try using a numbered or bar-coded wire seal to ensure that your drum contents remain intact.

Fire extinguishers.A depleted fire extinguisher will not ensure anyone’s safety.Please use convenient cable ties to ensure that each unit is fully charged.
For light security (such as postal service or air freight), prevent tampering with common or personalized loose plastic seals.

Pallets and crates.Labelmaster’s self-locking, tool-free trays and crate seals are the last step in safety construction – the strap cannot be broken, altered or replaced without your knowledge.

Rail cars.Sealing is actually mandatory in another place.But which one?We recommend using a steel bolt seal conforming to C-TPAT, which can only be opened with bolt cutters.

Semi-trailer.Did you know that 90 percent of thefts occur in the course of truck traffic?Secure trailer and cargo with steel bolted seals or consecutively numbered truck seals.

Storeroom and cage.For convenience and short-term safety, try using a color-coded plastic strap seal.Personalize them with your company name to prevent tampering.

The tanker.Only special tools can be used to open the tanker, so light seals may be all you need.We recommend using cable locks that comply with C-TPAT standards.

Valves, gauges and switches.Can a few cents save thousands of dollars?Yes – because simple plastic seals can prevent someone from accidentally opening, closing, or changing key valve, meter, or switch Settings.
