But purchasing karat or any scrap to refine is not considered purchasing an investment product. And any profit on metal purchased is first adjusted by considering the basis cost of the PM involved. Since a refinery is constantly taking in metals the difference between the incoming price and the sell price is small so any 33% tax is on a small number and even that is made smaller by operating costs.If you purchase some PM's, you can write that off as an investment. Any profit you make (capital gains ), are taxed at 33% on PM's
The tax code has to be straight forward otherwise figuring out an exact tax burden for every lot or transaction would be debilitating. That is why a refiners self assessment needs to be reasonable. There is a ton of wiggle room between when a refining product is considered working inventory, work in process, or profit. It all depends on how a refiner assesses it.
