Let me ask some question about your question this below mail ; you mean, you want to consultant RM in your products, is correct?
If yes, it will be very difficult because you have to do this with every product. Although it's old raw material, that we've discussed already, because we consult with DIW under your product name.
Your manufacturer will do discuss same raw material more than once? (I mean : They will send the same raw materials to DIW every time, if have that raw materials in our products. And we need to discuss with DIW.)
