However, if a manufacturer, wholesaler, or retailer sells several types of products, including those not subject to the litter fee, in a single department, his records must individually identify the types of products which are subject to the litter fee. A manufacturer, wholesaler, or retailer may report and pay the litter fee on the basis of a percentage of gross proceeds where the gross proceeds from sales of products subject to the litter fee do not exceed 20 percent of his or her total gross proceeds. The percentage reported must reasonably reflect the sale of the products subject to the litter fee.
