How so?  I can&#x27;t think of an industry that does this other than to make a product <i>specifically for measuring</i>, like tape measures.<p>A bigger trade issue is differing national standards, such as making left-side-driver versions of vehicles for those countries that drive on the right (much of the world that doesn&#x27;t speak English or Japanese).<p>BTW, did anybody get that &quot;Boeing 767 ran out of fuel midair&quot; story link to work?
