How do container seals and locks differ?

Ensuring the safety and integrity of goods during transportation is crucial in the shipping industry. Container seals and locks play significant roles in this process, yet they differ fundamentally in their functions and features. Understanding these differences is essential for selecting the appropriate security measures for cargo.

Definition and Function

A security seal is a single-use device used to lock containers. According to Marine Insight, heavy-duty container seals are designed to withstand harsh environmental conditions as well as to ensure the security of goods throughout long voyages.

The primary function of a security seal is to ensure that the container has not been tampered with or opened illegally during transit. Each seal comes with a unique alphanumeric identification number, which helps in verifying the integrity of the container’s contents throughout its journey. Once applied, a container security seal cannot be reused, as it gets damaged when opened.

In contrast, a container lock is a reusable device installed on the container door to prevent unauthorised access. While container locks also aim to secure the container during transportation, they can be used multiple times. These locks can range from simple mechanical devices to advanced digital password locks, offering varying levels of security based on the type and value of the goods being transported.

Practical Applications and Precautions

Once the container is loaded and the doors are closed, a security seal obtained from a specialist provider such as https://acmeseals.co.uk is applied to prevent unauthorised access during transit. The unique number on the seal is recorded on the bill of lading and must match the seal upon arrival to ensure the container has remained intact.

After confirming the cargo, a container lock is installed and, if necessary, a password is set. It’s crucial to select a lock that matches the security needs of the cargo. Ensuring the lock’s durability and reliability is vital to prevent tampering during transit.

While both container seals and locks are essential for securing goods during transportation, they serve different purposes. Selecting the right combination of seals and locks can significantly enhance the security of transported goods.
