We have unexplained and inexplicable custom logic of how a particular parcel passes customs clearance. I'll tell you my experience. Ordered at the time the CPU for 199 $ from USA (these Protsiv was not yet in Russia). Paid for urgent delivery by UPS within 2 days. Was waiting for my percent was waiting, but it is not. Call UPS and they tell me, saying that You ordered to the address which listed non-residential building (I live in the suburbs, ordered office address in your name) and custom requires a pack (then was read a list of) documents that the goods are imported not for the firm. In the end, the documents and the customs broker cost me in the area of 7K rubles, time to clearance took about a month and when I handed my % I was able to buy the same in all the stores of Moscow for a price comparable to the price in the United States.
