The first of all, I appreciate your effort to provide me with the documentation, though you’re not PIC.
But still I need some kind of certificate for the material. Invoice won’t do any good.
Again, would you please ask the manufacturer to give me that inspection certificate through OHGITANI (THAILAND) ?
(As long as they’re ISO corporation, they must keep the record for 5 years at least. So they should have one, I believe.)
