You don really know with any certainty. In some countries it may be only the stamp or label that was made in the country thereon. In many other cases it could be that only a certain percentage of the product was made in the claimed country of origin. In most manufacturing processes you can end up with a product that has multiple source countries involved and possibly only final assembly or value adding performed in the claimed country of origin. I should add that this is the norm for the greater percentage of products on the market. Apart from very nasty low end products there is nothing wrong with this. We enjoy quite cheap items at point of purchase so it no big deal to throw it away and get another when it fails. Yes it wasteful but who wants to pay double or triple the purchase price for a repair even if a repair is possible.
