This sort of chain-0f-custody applies in other fields as well. I
spent quite a few years as a quality assurance auditor in the
nuclear power industry and materials used there in safety-related
systems have to have pedigrees "back to the mine", as we
sometimes put it, and the supplier must supply a certificate
attesting to what the material actually is, which includes the
chem analysis for metals (a CMTR, or certified materials test
report). In my line of work we had to find evidence that proper
care was being taken with the materials and that a supplier had
programs in place that would properly track materials at each
stage of handling. When Kaiser Steel still operated in Fontana,
Calif, I watched them pour molten steel into ingots and made them
show me how they tracked each ingot through the plant, through
the rolling mill and on to the shipping dock and then on to the
truck.

I'm not certain, but it might also be used by the post office in relation to
registered post. The concept is certainly used, even if the term isn't.

In the food supply, the terminology for the same concept concentrates
on the outcome rather than the process: it's called "identity
preservation". There, the issue is making sure that a food product
with certain political (organic, non-transgenic, etc.) and nutritional
(free of some allergen, containing a certain amino acid mix, etc.)
properties makes it through the supply chain without adulteration. A
more involved description than even I care to read can be found at

That's not a custody chain, it is a record of process for a particular
billet, rod, sheet, so on. As long as that material can be unambiguously
linked to the record, it doesn't matter who has "custody" of the
material. Custody could be an issue if the storage environment is
important.

And for some equipment and materials, it is. Nevertheless, the
documents are no good unless it can be shown that the material
never left the documented chain. The chain of custody is as
important as the paperwork. Each holder of the mterial or
evidence basically attests that this is the stuff given to
him/her by the previous holder and is the stuff passed on to the
next holder.
