Deduction code library
Distributor remittances use cryptic codes — CVSN, (invoice#)29CM, IAA. This library decodes them and, unlike a bare code list, tells you whether each is disputable, what evidence wins, and how to file.

How codes map to dispute paths
A deduction code is only the label a distributor prints on your remittance. What matters is the path behind it: which billing category it belongs to, whether that category is usually disputable, what documentation defeats it, and the window you have to file. This library organizes every code under its category so you go from a code you don't recognize to the action you can take.
Many codes — especially UNFI's 3rd-party billing pass-throughs — aren't the distributor's own charge at all; they originate with an end retailer, which changes who you dispute with. Others, like weights-and-measures fines or recalls, turn on specific documentation. Start with your distributor's library above.
For the plain-English definitions behind the codes, see the deduction reason codes overview and the reason-code lookup tool.
