Heavy Equipment Declarable Substance List Committee (HEDSL)


The Heavy Equipment Declarable Substances List (HEDSL) harmonizes and simplifies the industry’s data collection efforts. Adopting a single list of known chemicals of concern, with agreed upon threshold limits, and clearly communicated reasoning, will help educate the supply chains on the regulatory needs of their customers, as well as simplify the reporting requests to which they need to respond. Ideally, one regulatory list and fewer reporting systems will lessen the regulatory burden on the entire heavy equipment industry.


The HEDSL Committee is responsible for reviewing global chemical laws, assessing potential risks to the non-road industry, and compiling and approving the HEDSL for public consumption.
