its not right that a iron can be a product material and a tricycle could be a raw material. they should fix it and get rid of the choice. wht sells in stores is a product material, wht doesnt is a raw material.

the problem arises when a resource/product is both for production as well as for sale
Take Glass.. what category would you default that to?
- It sells in shops, but is also used in a ton of productions (eg wine, and other bottled items)
Same goes for woodenboards, which also sells in shops, as well as beeing a resource used for other productions.I am not saying it isnt confusing, I'm just saying that its not 'right' to make the items go anywhere on default.
