Just for the sake of completeness, "knowingly" is a specific legalese term. It means you know the goods are coming from the prohibited source, but still decide to buy it.

The total spectrum looks like this:

- purposefully: you won't buy cobalt, unless it says "mined by slave children" on the tin

- knowingly: you buy cobalt even if it says "mined by slave children" on the tin

- recklessly: you know that 90% of world cobalt is mined by slave children. You hope that yours comes from the remaining 10%

- negligently: you know that 10% of world cobalt is mined by slave children, so you decided to take a chance and bought yours without checking

Isn't there another level which is only sufficient for crime if it is a Strict Liability law?

- accidentally: you know there's a risk of buying cobalt mined by slave children. So, you took the actions of a reasonable person to avoid that risk, but you failed.

Not sure I understand the difference between recklessly and negligently? Don't both amount to you not knowing and not wanting to find out?

Negligent means you didn't know and didn't want to, reckless meant you didn't know but accepted the possibility that it could happen or the possibility was extremely high.
