I am not asking to put this on - I am asking when we receive raw material from our supplier what has the copper manufacturer put on ( i.e. Sommers or Gould or Mitsui as examples of copper suppliers) .

I could be wrong, but I think that might be another name for OSP, Organic Solder Preservative... -Steve Gregory- Does anyone know what is in anti-tarnish?
