To call "African Amber" or "Copal" phenolic plastic beads or all other plastic beads is a severe misrepresentation. All plastic beads imitating amber (even if they are highly collectable) have to be represented as "Imitation Amber". There is no other possibility.
Concerning natural amber sold per gram in Africa and duly tested, representation as "Mauritanian Amber", "Amber collected in Africa" or Copal are acceptable but, if such a material is not fossilised (unlike Baltic Amber which may be more than 50 million years old), the seller should indicate that the material is immature and assimilable to Copal.
