Ii believe that is correct. And that imported clothes (most clothes, that's to say) can also be traced to a point of entry/ time of entry into the USA by their tags. For instance, the shirt might be known to have entered the us via a NJ sea port in winter 2007. Totally random example, but I heard that all legally imported clothes batches are recorded and the information is in the tags if the tags are still sewn in.
I think that I've seen that Rafealla (?) brand in MACY's. I am sure there are fashion/shopping people who would be sure of where that brand is distributed.
MOO; I recall the tag code info from some other case documentary.
