Are there customs implications regarding data loggers within cartons coming into the US?
Almost certainly not. The most authoritative statement we have in this regard is from a US regional sales representative of one of the largest global container lines, who says “It is the feeling of the experts in my organization that the insertion of [the iButton data logger] will not have customs implications.” This opinion has been confirmed by the import department of a global 3rd party logistics provider, with whom we consulted. However, if you still worry, amend your paperwork to state something like “50 temperature monitored boxes of wine” or “wine in temp monitored boxes”. The sales representative goes on to say that “It is thought that this [modifying the paperwork] is over the top and not required, but also will not have any customs implications to amend the paperwork.
