UNFI deductions, explained

ShelfKit guide · compiled August 24, 2026 · every claim below is sourced — see the confidence labels

UNFI takes money off your remittance and calls it MCB, a reason code, or a string like (invoice#)29CM — and UNFI's own code key is locked behind a supplier-portal Zendesk that the public web can't read. This guide tells you what's actually confirmed from UNFI itself, what's reported by deduction-recovery vendors who disagree with each other, and exactly how to pull your own key so you're not guessing either.

What a UNFI deduction is

When UNFI ships your product to a retailer, it sometimes pays for something on your behalf first — a discount, a promotion, a return, a fine for a shipping error — and then takes that money back out of your next remittance. The line item on your check or ACH statement is the deduction. It's normal; it's also frequently wrong, undocumented by default, or simply opaque until you ask for the backup.

The code schemes you'll actually see

We found four different naming schemes across independent sources, plus a fifth list of named fee programs that aren't "codes" in the strict sense. We could not confirm whether these are the same underlying system described four different ways, genuinely separate systems (natural vs. conventional vs. legacy vs. current), or individual vendors' own simplifications of UNFI's key. Present them to yourself the same way we present them here: as separate, sourced tables — never as one merged list.

1. MCB single-letter codes (East / West)
2. Numeric reason codes
3. Alphanumeric string codes
4. Three-letter conventional-side codes
5. Named fee & deduction programs

1. MCB single-letter codes — East and West regions Industry-reported

UNFI splits MCB sub-codes into East and West regional schemes, and the same letter means something different in each region — treat these as two separate tables, never merge them.

East region

West region

Note the letters that repeat from East above — with different meanings.

2. Numeric reason codes Industry-reported

A different vendor describes UNFI deductions as numbered reason codes rather than letters. This is a different naming scheme than the letter codes above — we could not determine whether it's the natural-side codes, a newer unified scheme, or this vendor's own simplification.

3. Alphanumeric string codes Industry-reported

A third naming scheme: string-based codes tied to invoice numbers or program names, published by OverDeduct (a paid deduction-management vendor) as a "UNFI code library." We read their free reference pages, not their gated tool.

Compliance & weights-and-measures fines

MCB & free-fill

3rd-party billing / pass-through

Retailer-originated charges UNFI forwards onto your remittance — dispute with the end retailer if the charge is wrong at source, escalate through UNFI for pass-through or documentation errors.

Recall & withdrawal

Advertising & ad-billing

Categories with no specific code string published

• Pricing / cost-discrepancy — "Short-pays where UNFI paid a different cost than you invoiced, or applied a deal you didn't agree to." Called "among the most recoverable UNFI deduction types."
• Shortage & misshipment — "money UNFI withholds because its warehouse recorded receiving fewer units than you invoiced, or logged product against the wrong purchase order." "Highly disputable."
• Freight allowance — "a discount UNFI takes to cover freight when it handles transportation of your product — typically a fixed percentage or per-pallet amount." "Often disputable" if the rate is wrong, you arranged your own freight, or the shipment was prepaid.

4. Three-letter conventional-side codes Industry-reported

A fourth, different scheme — reportedly specific to UNFI conventional suppliers (as opposed to natural), filed via UNFI's ePASS/SV Harbor portal rather than the natural Dispute Center.

Also reported on the natural side, same article family: Barcode Non-Compliance Fee, Pallet Labeling Non-Compliance, Late Delivery Penalty, No-Show Delivery Fee, Quality-Based Manufacturer Chargeback, Quantity or Pricing Discrepancy.

5. Named fee & deduction programs Industry-reported

Not "codes" in the strict sense — named charges UNFI applies that suppliers and vendors describe by name rather than by code string. Figures marked single-source below are exactly that: reported once, not corroborated elsewhere, and should be treated as illustrative rather than authoritative.

How to get your deduction key and backup

Industry-reported, corroborated across independent write-ups unless noted. UNFI's dispute process differs by supplier type.

Natural suppliers

• Current process: UNFI's Dispute Center, inside the myUNFI supplier portal. Log in, then click the "GO TO DISPUTE CENTER" button. A new version of the Dispute Center is reported to have launched February 2026.
• Steps: locate the payment/adjustment via Quick Search, Advanced Search, or My Docs → select it → click "Create Dispute" → enter the disputed amount and explanation, optionally attaching a PDF, TIFF, JPEG, XLSX, or CSV up to 20MB → submit and get an email plus inbox confirmation.
• Status tracking: Draft → Submitted → Research In Progress → Pending Approval → Approved/Denied.
• Older/parallel process: emailing Deductions@unfi.com a completed Excel "Dispute Form," subject line formatted Dispute: [Brand Name], [Check #], [Deduction Invoice #], [Dispute Amount]. Industry-reported (SPS Commerce) for the address and subject-line format; what UNFI's own Zendesk stub confirms is only that a downloadable "Deductions Dispute Form" (.xlsb) exists and is required to dispute natural deductions "taken in error."

Conventional suppliers

• File through UNFI's ePASS platform via the SV Harbor portal (epass.svharbor.com/epass/home). Access setup goes through MerchandisingServices@unfi.com.

Non-portal exception channels

Certain deduction types reportedly go by email instead of through either portal: AP Cash Terms → UNFINaturalResearch@unfi.com; SAS disputes → UNFICorr@sasrecovery.com; SASIF → UNFIFrt@sasrecovery.com; PRGX-related → UNFIAudit@prgx.com. SAS Recovery Solutions and PRGX are third-party audit/recovery firms UNFI appears to contract with for specific deduction categories.

Filing window — sources disagree, and we won't pretend they don't

This is reported inconsistently across every source we checked: "typically 30-60 days from the deduction date" in one framing, "within 60 days... up to 12 months is allowed" in another, and a conventional-specific framing of "within 60 days... up to 12 months to dispute after issuance" in a third. Every source agrees disputes older than roughly 12 months are denied — that's the one number we're comfortable stating. One vendor states outright that "filing deadlines vary by deduction type and by your UNFI agreement," and we found no single UNFI-attributed, unconditional number on any UNFI-owned page we could access. Don't let anyone — including this page — tell you a single fixed day count is UNFI's official policy.

Resolution timeline and acknowledgment

Two independent sources put resolution at roughly 30-45 days ("35-45 days" per one, "typically 30-45 days" per the other). UNFI reportedly acknowledges a submitted dispute with a tracking number within two business days. Only one appeal is allowed per dispute, and it must include new information or additional supporting documents; if a partial repayment was made, the appeal covers only the remaining unpaid amount.

Backup documentation, by deduction type

Common gotchas operators report

Industry-reported, each sourced individually.

• MCB/promo billbacks fund things you agreed to, but the amount is opaque by default. Multiple sources independently flag that MCB line items only become legible once a supplier proactively requests UNFI's backup detail file — without it, the remittance line just says "MCB" with a dollar figure.
• Duplicate deductions. A promo deduction applied twice, or coded under two different reasons, is called out as a recurring pattern worth auditing for.
• Early-payment (cash) discount taken even when payment was late — i.e., the ~2% discount taken regardless of whether the discount window was actually honored. Reported independently in two places.
• Freight/handling deductions must match your actual agreement. A common recoverable error is UNFI applying its standard freight allowance rate even when the supplier arranged or paid freight itself, or on a prepaid shipment.
• Compliance fines stack from small, easy-to-miss operational misses — a shipment missing a packing slip, or a missing/late ASN. Specific dollar figures for these come from a single uncorroborated source; treat them as illustrative, not authoritative.
• Spoils/unsaleables allowances are usually a standing percentage-based deduction (Fairshare-style), described by vendors as "almost always non-negotiable" — separate from one-off spoilage chargebacks tied to specific lots.
• Compliance/logistics violations reported as common root causes: delivery outside the scheduled appointment window, shipment routed through an unapproved carrier, pallets configured wrong for the receiving DC (mixed-SKU where single-SKU is required), and BOL/PO/case-count mismatches against the physical shipment.
• UNFI's compliance-fine categories map onto the routing guide: weights-and-measures, ASN/EDI accuracy, routing compliance, and label compliance are each their own fine family, each independently disputable with the matching evidence type.
• Suppliers reportedly avoid disputing out of fear of being deprioritized or getting reduced orders — several vendor write-ups cite this as a reason deductions go unchallenged and losses compound over time.

What nobody outside UNFI can verify

This is the honest part. We tried to fetch UNFI's own pages directly wherever possible; here's exactly where that failed and why.

• The actual contents of UNFI's Supplier Deduction Key spreadsheet. Confirmed to exist; never read. Every specific code string anywhere on the public web, including on this page, is a third party's transcription of that key — not a direct reading of it.
• A single authoritative dispute filing window. Covered above — sources give different numbers and agree only on a roughly 12-month outer limit.
• Whether the four code-naming schemes are one system or several. East/West MCB letters, numeric Reason Codes, alphanumeric strings, and three-letter conventional codes could be the same system described four ways, genuinely separate systems, or vendor-specific simplifications. This is a real, unresolved conflict across our sources.
• Current, UNFI-sourced dollar and percentage figures for the recall administrative fee, service level fine, overship charge, and per-incident compliance fines — each traces to exactly one source and none of them is UNFI itself.
• Whether the East/West regional contact emails still work. The only source we found for deductions@unfi.com and wrap@unfi.com as region-specific contacts is a 2019 UNFI Zendesk snapshot. We found no 2025/2026 confirmation, and the ecosystem has since moved toward the Dispute Center plus third-party-firm emails for specific categories — treat the 2019 routing as likely stale.
• UNFI's own live "Deductions FAQ" page as it reads today. The URL is currently linked from UNFI's own Deductions section index, but UNFI's Zendesk returns HTTP 403 to automated fetches, and no web archive holds a snapshot newer than 2019.
• unfi.com/supplier-terms.html. Protected by bot-mitigation on both the live site and Wayback's re-crawl attempt; we could not read anything from this page.
• The SSA 2.5% rate as still current in 2026. Dated to a May 1, 2024 introduction from one source; the 2026 update describes a billing-format change and states the rate is unchanged, but neither claim comes from a UNFI-owned document.

If you need a code to be authoritative — for a dispute packet, for your books, for anything that matters — the only real answer is to pull UNFI's current Supplier Deduction Key from inside your own myUNFI portal login. Nothing on the public web, including this page, is a substitute for that.
