OK, I’ll admit your question has raised my curiosity...to the extent that the obvious should be asked. That is, why do brand new containers have an appeal to you over used ones?
IMHO, backed by over ten years of exporting out of Indonesia, frankly, I avoid new containers. This isn’t because of any illegal activity, fun as it might be to speculate, but rather hard knocks and learning just how much it costs to have a container emptied by US Customs for 100% inspection, only to find out later that repacking the container in the same was it was originally packed was mission impossible IV...and this easily added $2,000.00 to the original container load.
So, why the interest in new containers?
