Understanding the Role of the Association of American Railroads (AAR)
The Association of American Railroads (AAR) plays a pivotal role in maintaining the safety, efficiency, and standardization of freight rail transportation across North America. As the governing body that sets technical standards and regulations for railroads and rail-related equipment, the AAR is particularly influential in the realm of load securement—a critical component of cargo integrity and transport safety.
When it comes to protecting goods in transit, AAR verification is not just a benchmark—it’s a necessity. This is especially true for companies like International Dunnage, which prioritize quality and safety in cargo protection solutions such as dunnage airbags.

Why AAR-Approved Load Securement Matters
Rail transport involves high levels of dynamic movement, with cargo subjected to longitudinal and lateral forces that can shift or damage goods if not properly secured. The AAR’s Open Top Loading Rules (OTLR) set forth the guidelines for securing cargo safely during rail movement. Failure to comply can lead to serious cargo damage, regulatory penalties, or even derailments.
The AAR approval process evaluates whether load securement products—including dunnage bags—meet the required strength, durability, and inflation standards to withstand the rigors of rail transport. It is essential to review and comply with the Open Top Loading Rules that are outlines in AAR Open Top Loading Rules Manual.
AAR-Verified Dunnage Airbags: A Standard of Excellence
International Dunnage proudly offers AAR-verified polywoven dunnage airbag solutions designed to meet the stringent requirements of the rail freight industry. Our airbags undergo rigorous testing under the AAR RP-4 standard, which evaluates:
- Inflation and deflation performance
- Burst strength under simulated rail conditions
- Resistance to pressure loss
- Structural integrity under varying temperatures and loads
By achieving AAR verification, our dunnage bags are qualified for use in
railcar void-fill applications, providing peace of mind to shippers, logistics providers, and end-users.
If you are in the market to purchase dunnage airbags, do not forget to check first if the vendor has verification for the specific type of airbags you intend to buy. While using AAR-verified
dunnage bags are mandatory for railroad shipments, it is advised to use AAR-verified bags in any transportation mode as it adds an additional quality check.
