I used to work in incoming inspection at an aerospace manufacturing company. And now work in technical sales (industrial automation).
If you want the tolerances changed my advice would be to go to the purchaser at your company and suggest that they seek quotes from a different supplier at whatever you think the actual tolerance should be.
Purchasers are often incentivized for cost reductions.
Obviously this only works from a parts receiving context though.
