There is a difference between what we should do and what we are able do.

If I had 50 supposed martian meteorites up to 8 gram I would like to
have a scientist look them over so nothing is lost for science. In this
case I think there shouldn't be any problem to find a lab that wanted to
take a look. Let the lab verify that all stones are martian or at least
most probably martian if they match them visually and only test a few
stones.

If I had (which I do) 50 meteorites under 8 grams that looks like
ordinary NWA weathered stones then I don't think I could find any lab
that wanted to classify them even if I donated the whole lot.

In a perfect world every meteorite should be classified, measured,
positioned and registered but we can only do a limited amount of work
and that should be done where we (science) get the most value. To
classify more Mali, NWA 869 or Camel Donga is probably just a waste of
money.
Best of all is if dealers and collectors keep an eye out for strange
stones among the ordinary ones. I don't remember exactly but I think
someone had a scientist going over hundreds of kilos of NWA 869 to
cherry-pick some interesting stones. Haven't heard any result though.

Of course, the rules are only suggestions and no one is enforcing them.
Some dealers classify their martian meteorites and some is selling them
unclassified but still calls them martian.
