First of all, sorry for my late reply.
As I’ve already explained to you via phone that it is difficult to compare NT (Thailand) cost with FNI (Indonesia) cost.
Since, there are too many different factors such as exchange rate, production volume and others.
As you may know that FNI produces and supplies to Yamaha with big volume while NT produces and supplies with smaller volume.
However, we try to continually improve our process cost and cooperate by submitting the VA proposals to you.
Moreover, we’ve never requested to increase the price even the actual volume is lower than the quotation volume.
Please kindly understand our situation, thank you.
