you need to ask some advise from the logistic import export people
becos can reduce the tax if u know how to declare the item
for example
if u import construction machine, if u declare the purpose of the machine is for construction, sure one the tax is higher
but if u declare the machine is for agricultural purpose, u can reduce the tax
its all depend how u fill up the form plus what "kInOzAwA" said
plus also depend on the custom guy
just my seposen thought
