I am just getting into the PI business…at least to understand how it works. I am in Hy-sec .

I have a question on custom office tax. I understand the NPC rate in hy-sec and player corp add on but what I don’t understand is what is the tax based on?

For example: I produced 70 units of Coolant and move it thru at a Customs office which had a tax rate of 12% for a tax of 60,480 isk. this means the tax was based on the value of 504,000 isk which is 7200 isk per unit.

Where does the customs office get the 7200 isk per Coolant unit figure? this is about 1000 isk higher then the buy price at Jita. Is this a set price or is it based on something else? Is there a base number and the tax is added to it which would mean the more you transfer at one time the lower tax per unit will be?

Thanks
