First of all there is no sea freight cost in each offer, please ask Michela. Ask how many container (40 feet or 20 feet) for each offer.
Secondly, there is only 1 double pipe suction probe for 2 dryers. Why not 2 units of suction probes one for each dryer. I do not understand.
Please confirm with Carlo that 1 3 phase is for 2 hopper receivers ?
Third, in each offer you can see that you have to select either full frame with parapet or compact frame. (You can see on the 2 drawings with and without ladder)
Therefore; I think you should offer full frame with parapet for DP1700 the height is almost 6 m. (offer 15_00003)
And for 4 dryers offer 15_00005 I think you should make in 2 offers one with full frame (see version A) and the other one with compact frame (version B)
In you price cal = (Net price vismec to MT x 45 THB) / 0.65 for factor x 1.15 from import and inland transport
Let me suggest you as follow:
Always include the sea freight in the price cal, in your formula sea freight cost is missing
