Dear Nunghatai / Mr. Yutthana,
After discussing with my superior
we have decided that there will be no charges for the copper piping as to support Hansol Technics
but we have one concern
Will there will any issue at your side if we send the piping together with the PM/Cal reports when you receive them.
If is ok, we will indicate the copper piping as sample in our courier package
Kindly advise, thanks.
