UNFI deduction codes

MCB & free-fill deductions

MCB (manufacturer chargeback) and free-fill codes bill back promotions, scans and free-goods requirements you agreed to fund. Valid, authorized programs are legitimate; duplicates, off-window claims and unauthorized deductions are recoverable when each MCB is matched to an approved deal.

What these codes are

UNFI MCB codes pass promotional and trade charges through on your remittance — scans, off-invoice discounts, sales-velocity report fees and program-based charges tied to deals you agreed to fund. Free-fill codes cover free-goods requirements, often at launch.

These are partly disputable. The charge is legitimate when it matches an approved deal; it's recoverable when it's duplicated, applied outside the agreed window, applied to the wrong SKUs or rate, or claimed with no authorization on file. The work is reconciling each MCB code to the deal it claims to represent.

UNFI provides MCB backup on request — supporting detail you need to reconcile what you actually approved. It is typically sent on a weekly cadence to one recipient per supplier account.
