If it's a dangerous good and meets the requirements of the act and the regulations, then the answer is yes. If it's in the notion of import, handling, transporting, or offering for transport, then it would. If you took a dangerous good and you upgraded it and it became a new dangerous good that had some value added in a different product and you wanted to sell that and transport it, then yes, you'd fall under the act.
