You need to know certain details about the goods when applying the nomenclature. Examples of the details needed:
By examining the nomenclature you can find out what details you need for specific goods. For instance, when classifying a knitted fabric made of cotton and belonging to heading 6006, you have to know if the fabric is unbleached, bleached, dyed, knitted from yarns of different colours or printed. These alternatives can be found in the descriptions of the subheadings.
You also need detailed information about the goods when asking the Customs Information for help with the commodity code.
