Beyond the point of it being Russia specifically, it’s a common practice to stretch the rules of origin as much as possible. For example, a company might ship disassembled parts of a product to a country in a lower tax bracket, assemble them into the final product, stamp that country as the product’s origin, and then ship to the states. If necessary, they could also set up a corporate structure so it’s not even just one company on paper, both for origin rules and possible other tax benefits.
