A penny per concrete masonry unit manufactured and sold within the United States will be assessed once and only once. The assessment occurs at the initial point of sale from the manufacturer, regardless of where or with whom that transaction occurs. These assessments will be at the time of invoicing. The funds will be transferred on a quarterly basis to the checkoff and used to support initiatives intended to advance the industry.All manufacturers that produce and sell concrete masonry units will pay the same assessment at the same rate. Concrete masonry units are defined as any man-made masonry unit having an actual width of three inches or greater manufactured from dry-cast concrete using a block machine.
