A * after a commodity item indicates that the commodity item is a generic term, which does not rule out the possibility that the generic term also appears in other categories. For example, chestnuts fall into 25 categories, with clothes at 250 1 *250045, clothes at 2502 *250045 and clothes at 2503 *250045 and 25003. "Clothing" here is a general term, which may appear in different subcategories, so it is marked with * to show the difference.
