Lab testing, customs, a reship fee — anything you paid on top of the vendor's invoice — goes on the purchase itself.
These reach your true cost: cost of goods, margin, inventory value and total invested. They deliberately do not reach the $/mg vendor comparison, because a lab fee you paid a third party says nothing about whether that vendor is cheap. Mixing them in makes an honest supplier look expensive.
Already filed something as an expense? Move it onto the purchase and it comes out of expenses in the same step, so it's never counted twice.
