Sorry for our late reply. We had to analyze the numbers before sending our response to you.
Column I = USD/pc using Sumitomo pipe
Column J = THB/PC using Sumitomo pipe
Column K = USD/pc using TPCO pipe
Column L = THB/pc using TPCO pipe
Column M = 5% discount on THB/pc using TPCO pipe
Column N = Current price to RPB using Sumitomo pipe.
The analysis clearly shows we are selling fittings made from Japanese pipe at a loss. Most of the prices that you current get using Sumitomo pipe is even cheaper than what we sell using TPCO pipe. The exception are coloured in orange.
As advised we will be cutting down our use of Sumitomo pipe due to their high prices and will mostly use TPCO pipe. We will still keep your prices in column M, but supply TPCO pipe. The prices we give to RPB will still be the best when compared to other customers, especially customers in Singapore and Indonesia.
The last time we sold 500 pcs of 4” 90LR S40 WPB to you, we again gave you a special price of THB254.60. We will continue to give you special prices where possible.
I have already discussed this with K. Paiboon.
Thank you and please feel free to get in touch with me for further clarification.
