Are components exempted? - it depends on the sales situation
A PC consists of a number of components such as power supply, graphics card, motherboard, sound card, hard disk, RAM, CPU, etc. incorporated in a case. When the different parts are sold in large volumes (bulk) to a company that exclusively uses the parts to assemble and sell finished computers the different parts are considered as components. The finished PC is then covered by the rules on producer responsibility.
If, however, the parts are sold separately to an end user (retail packs) they are all considered as finished products and thereby covered by the rules on producer responsibility.
Other equipment that is typically used together with the PC, such as screen, keyboard, mouse, external hard disk, or external CD drive are also considered as finished products in their own right and are covered by producer responsibility.
