The trucking market has grown strongly in recent years, from $2.28 trillion in 2024 to $2.49 trillion in 2025, with an average annual growth rate of 9.4%. One of the most widespread uses of security seals is in trucks, which makes truck seals more widely used in transportation.
This blog will explain the types of truck seals and some of their advantages and application scenarios
The Growing Importance of Truck Seals in the Modern World
The trucking industry is a massive global operation. There are nearly 1 billion commercial vehicles in use worldwide, and in the U.S. alone, there are roughly 2 million semi-truck and trailer combinations operating daily. This means security seals are used in the hundreds of millions annually, with numbers only continuing to rise.
ProtegoSeal has been specializing in safety seals since 2010. At that time, there were only a few trucks, but as logistics evolved and the demand for truck transportation grew, ProtegoSeal is now one of the leading truck seal manufacturers, supporting a wide range of industries around the world.
While it’s difficult to pinpoint the exact number of truck seals used every year, one thing is clear: the demand for these products is huge. Whether it’s a tanker truck, flatbed, or a specialized delivery vehicle, seals are an essential part of securing goods, maintaining transparency, and preventing fraud.
Key Benefits of Truck Seals
Truck seals provide security, traceability and compliance to a wide range of industries. These seals play a critical role in maintaining cargo integrity, ensuring regulatory compliance and preventing theft or tampering.
What are the main advantages of truck seals? What are their specific functions? What is the working principle? What are the actual application scenarios? Let’s explain one by one
1. Tamper Evidence for Secured Transport
specific functions: Provide clear evidence that cargo has been tampered with. Once the truck is sealed, cargo is secured from unauthorized tampering.
How It Works: The seal is used on truck doors and once tampered with, it cannot be resealed or reused. Simple and effective protection against cargo theft
Example: A shipping company uses high-security bolt seals on their trucks. If a seal is found broken upon arrival, it’s clear that the cargo has been compromised, and they can take the necessary steps to investigate.
2. Compliance with International Standards and Regulations
specific functions: Countries around the world have specific regulations regarding cargo security in international freight, and tamper-proof truck seals can help companies comply with these standards.
How It Works: Many countries require truck seals, especially those involved in international trade, to comply with ISO 17712. These seals are often tested to withstand forceful damage or tampering, ensuring they remain intact during transport.
Example: Cross-border shipments between the US and Mexico use ISO-certified cable seals to comply with customs regulations. This ensures that both governments recognize the seal’s authenticity and that the cargo has not been tampered with during the journey.
3. Enabling Better Traceability and Tracking
specific functions: Track your shipment from start to finish using modern methods such as barcodes, RFID chips or QR codes.
How It Works: Truck seals equipped with barcodes or RFID tags allow businesses to track the exact location and status of shipments as they move through the supply chain. This improves communication between supply chain partners and enables real-time alerts for issues such as delays or tampering.
Example: A food distributor uses plastic pull-up seals with RFID tags on every truck shipment. These seals allow them to monitor the truck’s journey in real time, ensuring timely deliveries and alerting them to any unexpected deviations.
What Types of Seals Are Used for Trucks?
Fixed length seals made of plastic and metal are the most common truck seals. As distribution systems continue to evolve, more specialized seal options are available.
1. Metal Strap Seals : This is a classic truck seal that is still widely used today because of its simplicity and effectiveness.
2. Pull-Up Seals: These seals are often used on tank trucks, which require longer, more flexible seals.
2. Padlock Seals: Many people associate padlock seals with electric meters. But padlock seals are also a great option for truck security.
3. High-Security Bolt Seals & Cable Seals: High security bolt seals and wire seals: Mainly used for high value goods or international transport. Generally these seals need to meet ISO-7712 standards, which are recognized worldwide for their strength.
Choosing the Right Seal for Your Trucking Application
When it comes to selecting a truck seal, there are a few things to consider:
1. Think about the level of security you need. If your truck is carrying valuable or sensitive cargo, you’ll likely need a higher-security option, like a bolt seal. If it’s a routine shipment with less risk, a plastic pull-up seal might be sufficient.
2. Consider your operational needs. For companies with complex supply chains, barcodes and tracking numbers on seals can help streamline inventory management and provide real-time updates on deliveries.
3. Don’t overlook regulatory requirements. Depending on the type of goods you’re shipping and where they’re headed, your seals may need to meet specific standards. For example, for international shipments, certain seals must meet ISO-7712 standards for tamper-evidence.
