Chapter 94 covers furniture, bedding, lighting fittings and prefabricated buildings. Note 2 holds the key: furniture is an article designed to be placed on the floor or ground, or, by exception, hung on a wall where it is a storage unit or a seat.

Every number opens on the lines beneath it, down to the eight-digit statistical code.
