Security Seals

Tamper-evident seals are designed to provide clear visual evidence if a shipment, container, or package has been opened or compromised. They are essential for securing freight and sensitive materials during transit or storage, helping businesses protect against theft and maintain security protocols.

High-security seals prevent tampering by using durable materials like steel, heavy-duty plastic, or galvanized cable. Once locked, they can only be removed by being broken, which leaves unmistakable evidence of interference. Many seals also include unique serial numbers or barcodes for traceability, making them ideal for US logistics and C-TPAT compliance.

The main difference lies in their design and application. Bolt seals use a rigid metal bolt and locking mechanism for maximum security, typically for shipping containers at US ports. Cable seals use a flexible, cut-resistant metal cable, making them more versatile for securing trucks, railcars, and industrial equipment. Both are classified as high-security container seals.

To properly apply a pull-tight security seal, simply insert the tail end of the seal through the locking chamber and pull it snug. These adjustable seals are perfect for securing bags, totes, and various cargo sizes. Always record the unique serial number for a secure chain of custody.

A shipping seal is considered C-TPAT compliant when it meets the ISO 17712 standard for high security. This ensures the seal is highly resistant to tampering and meets the stringent requirements of US Customs and Border Protection. Bolt seals and heavy-duty cable seals are the most common choices for achieving compliance.

For warehouse shipments in the United States, the best seal depends on the application. Pull-tight seals offer great flexibility for securing bags and totes, while truck seals are the ideal choice for securing trailer doors. Using numbered security seals also helps with tracking and inventory management throughout the logistics chain.
