While true in most cases. I used to work as fabricator for a company that builds drilling platforms. We sourced stuff from all over. However, we quickly learned that there is a huge difference in the quality of steel coming from our supplier in Brazil. We kept having failures of our drills after switching to the Brazil supplier. The solution was to either make the steel thicker or up the grade from Brazil. Both of which, negated the steel savings by going to them. Ended up sourcing the steel locally, same grade, same thickness as the steel coming from Brazil, yet the mast failures stopped.
