IMO,

Incoming material should be checked, there is small devices to check copper
thickness

If not detected with incoming.. then when etching the result will show
either not completely etched.. which leads to suspicion of incorrect copper
thickness, or over etched leading to same. In both cases we are in trouble,
both the manufacturer and the supplier..

Then UN will send US militaries .... oups... no, Manufacturer's lawyer will
contact supplier's lawyer... we will likely end up like grown ups settling
the matter through our quality specialist that will ask for guarantees that
it won't be possible to happen in the future ... and get substancial credit
note over some more material... if this is a repeat, then you won't be the
supplier of this PCB manufacturer...

I have an other question to you...

What are the copper thicknesses that are available on the market today ?

0.125 oz
0.250
0.5
1.0
2.0
3.0
???
