What Are Container Bolt Seals?
Container bolt seals are critical security devices used to protect container cargo during transport. A container bolt seal is usually made of metal or plastic and is specifically designed to lock the container door leaf, preventing unauthorized access, tampering, or theft. These seals are required in international shipping and are essential for ensuring that containers arrive at their destination safely and intact. The proper use of container bolt seals is crucial for maintaining cargo integrity and preventing logistics losses.
Learn About Container Bolt Seals
A. What Is a Container Bolt Seal?
A container bolt seal is a tamper-evident locking mechanism that consists of a metal or plastic bolt and a locking cap. It is used to secure the container’s door handles, ensuring that the container remains closed and sealed during transit. Only by breaking the seal can the container be opened, providing a clear sign of tampering if unauthorized access occurs.
B. Types and Characteristics of Container Bolt Seals
Container bolt seals come in various types, with the most common being:
- Metal Container Bolt Seals – Known for their strength, durability, and resistance to tampering.
- Plastic Container Bolt Seals – Lighter in weight, easy to apply, and suitable for short-distance or lower-risk cargo.
Different bolt seals may feature barcodes, serial numbers, or RFID tags to aid in tracking and verification.
C. Purpose in Cargo Transportation
The primary function of container bolt seals is to ensure that containers are not tampered with or opened by unauthorized personnel during transportation. They also enhance the overall safety and reliability of the logistics chain.
Correct Installation of Container Bolt Seals
A. Step-by-Step Guide
To ensure the effectiveness of container bolt seals, follow these steps:
Record the seal number for future inspection and documentation.
Align container doors properly.
Insert the bolt of the seal through the latch hole.
Attach the locking head until it clicks and securely locks.
Check that the seal is firmly in place and cannot be removed without being broken.
B. Why Proper Installation Matters
Correct installation of a bolt seal is the first step to securing your cargo. A poorly installed bolt seal may result in security failure, cargo theft, or regulatory violations.
C. Common Mistakes to Avoid
- Loose or unclicked bolt seals
- Using damaged or previously used bolt seals
- Skipping verification of seal numbers
Avoiding these mistakes ensures that your container bolt seals perform their protective function throughout the journey.
