Your last sentence is not accurate. Please post a link to ups.com or the UPS service guide that indicates there is a "revenue correction surcharge." UPS has several charges that "catch" people after the package is shipped (i.e. address correction, residential/commercial adjustment, late payment fee, etc.) but there is no such thing as a revenue correction surcharge.
As for an additional charge for weights being off I have not seen that from UPS or Fedex, they just adjust it via re-weigh/scan at the hubs. UPS seems a bit more liberal, seems every Fedex package gets re-weighed and scanned. You are just charged what they find, nothing additional.
In terms of something that can incur an extra charge that perhaps NY is alluding to: (And it happens in real-life to)
There is a revenue correction charge, not saying it is named exactly that, when an invalid 3rd party account or Credit Card is used. Or even a refusal of 3rd party paying byt the 3rd party.
"package is shipped to an unauthorized consignee" is another, but I don't really know what this one means.

Missing/Invalid Account Number or Refusal Fee; Chargeback for Consignee Billing Shipments
A processing fee will be charged for a missing or invalid account number when the account
number is missing, the account number is not the correct number for the bill-to party,
the account number is for a receiver or third party who fails to pay the shipping charges,
or the package is shipped to an unauthorized consignee.
–
In the event of non-payment by the consignee or third party, the original shipper will be billed
a refusal fee in addition to the shipping charges
$12.35
Fedex has the same thing, they charge $12.00

Just remember who shares links and doesn't just say stuff and use "trust me". Referencing the discussion had about Insurance Cadillac Plans, I'm almost certain you guys will be in for a treat. I backed it with several links I shared, were I believe everyone else had not links and used the words... "trust me".
There is nothing I can find, nor have I ever seen a surcharge for the weight being off, just an adjusted weight charge of what it would have cost if the weight was correct on the label to begin with.
