Aerosol Container Test Method Evaluation and Regulatory Analysis

The contract seeks evaluation of test methods outlined in DOT special permits DOT-SP14940 and DOT-SP20638 as they apply to aerosol containers, with the goal of determining their suitability for inclusion in standardized regulatory rulemaking. The assessment will focus on technical validity, repeatability, and regulatory feasibility to support potential harmonization or adoption into federal transportation safety standards for hazardous materials. This work is critical to ensuring consistent, science-based criteria for the safe transport of aerosol products across all modes of transportation. The effort is being conducted under subcontract authority by the Department of Transportation’s 693JK3 Acquisition Services Division, with performance centered in Washington, D.C., and a response deadline of August 1, 2026. The effort falls under NAICS code 541690 for other scientific and technical consulting services, indicating a focus on expert analysis rather than physical testing. The outcome will inform future regulatory decisions by the Pipeline and Hazardous Materials Safety Administration and could impact industry compliance practices, packaging design, and hazard communication requirements for aerosol containers nationwide.
