Walmart Compliance Guide: What to Know in 2026

Selling to Walmart requires meeting strict standards across two core programs: OTIF (On-Time In-Full) and SQEP (Supplier Quality Excellence Program). Failure to comply results in chargebacks of 3% of cost of goods on non-compliant shipments. Suppliers must maintain a 90% on-time rate, 95% in-full rate, and meet exact labeling, packaging, and EDI requirements to protect margins and shelf space.

Introduction: Why Walmart Compliance Is Non-Negotiable

Walmart retail compliance directly determines your profitability, shelf placement, and long-term status as a supplier. Brands and CPG founders selling to Walmart must navigate two interconnected compliance programs that govern every aspect of how products are shipped, labeled, and received.

This guide is for brand founders, supply chain managers, and retail merchandisers who need a clear, actionable roadmap to stay compliant, avoid chargebacks, and protect their relationship with Walmart. Whether you're a new supplier or a seasoned vendor looking to shore up your compliance scorecard, this guide covers everything you need to know.

What Are Walmart's Two Core Compliance Programs?

Walmart's supplier accountability framework runs through two programs: OTIF and SQEP. Understanding the difference is the foundation of any compliance strategy.

OTIF: On-Time In-Full

OTIF measures delivery performance specifically whether your shipments arrive at Walmart distribution centers on time and with the correct quantity of product. Walmart tracks OTIF at the case level, not just the purchase order level.

Current OTIF targets (as of February 2024):

• On Time (Prepaid suppliers): 90% of all cases must arrive within the Must Arrive By Date (MABD) window
• Collect Ready: 98% of all cases must be staged for Walmart pickup on time
• In Full: 95% of all ordered cases must arrive at the DC

Missing these targets triggers a 3% chargeback on the value of non-compliant cases. For a brand shipping $50,000 per week, a 10% OTIF miss can cost $1,500 weekly — or $78,000 annually.

SQEP: Supplier Quality Excellence Program

SQEP covers how products are prepared, packed, labeled, and documented before they ever leave your facility. SQEP is divided into phases:

•       Phase 1 — PO Accuracy: The final purchase order must match items shipped exactly.
•       Phase 2 — Barcode & Labeling Compliance: All cases must include scannable GS1-128 barcodes and labels that meet Walmart's placement, size, and identification standards.

MABD: The Most Misunderstood Compliance Requirement

Must Arrive By Date (MABD) is the single biggest source of OTIF fines for Walmart suppliers. MABD is the date Walmart expects your shipment to arrive at the distribution center. It is determined by lead time, shipping method, and Walmart's internal routing assumptions.

Critical MABD rules:

• Arriving early can still be non-compliant — Walmart DCs plan capacity tightly and do not want product before their window.
• Prepaid suppliers have a two-day window for general goods; produce and perishables have a one-day window.
• OTIF data typically lags real-world activity by one to two weeks, and fines are often posted four to five weeks after month end.

Practical tip: Treat OTIF as an ongoing operational metric, not a month-end cleanup task. Check your OTIF Scorecard in Retail Link weekly to catch projected fines before they become invoices.

Packaging and Labeling Requirements

Walmart's packaging and labeling standards are among the most detailed in retail. Non-compliance triggers SQEP chargebacks and can result in product being held or rejected at the DC.

Barcode Standards

Every case must include a GS1-128 barcode meeting Walmart's specifications for print quality, size, position, and white space. All barcodes must be scannable. Labels must match item setup exactly — including description, quantity, and UPC.

Secondary Packaging

Walmart updates its Secondary Packaging Standards annually. Current requirements cover:

• Case durability and size requirements for movement through Walmart's conveyor-based distribution centers
• Vendor pack (VNPK) and warehouse pack (WHPK) configurations
• Label placement, carton markings, and identification standards

EDI and ASN Requirements

Electronic Data Interchange (EDI) compliance is a prerequisite for selling to Walmart. The Advance Ship Notice (ASN), sent as an EDI 856, must be submitted promptly after receiving a purchase order.

Key ASN requirements:

• The ASN must match the PO exactly — items, quantities, and configurations.
• The shipment must then match the ASN. Mismatches generate SQEP chargebacks.
• For food and beverage suppliers, ASNs must now incorporate FSMA 204 Key Data Elements (KDEs) per Walmart's August 2025 traceability mandate.

New in 2025: All food and beverage suppliers must comply with FSMA 204 ASN and packaging traceability requirements. Walmart has stated it expects suppliers to meet these timelines regardless of the FDA's 30-month extension to 2028.

Walmart Compliance Requirements at a Glance

Compliance Area	Key Requirement
OTIF — On Time	90% of cases arrive within MABD window (Prepaid)
OTIF — In Full	95% of ordered cases delivered
OTIF — Collect Ready	98% staged for Walmart pickup
OTIF Penalty	3% of COGS on non-compliant cases
SQEP — PO Accuracy	Final PO must match shipment exactly
SQEP — Barcode	GS1-128 scannable barcodes; labels match item setup
ASN (EDI 856)	Must be sent promptly; match PO and shipment
FSMA 204 (Food)	KDEs required in ASN for all food/beverage items
Dispute Window	15–30 days from chargeback posting via HighRadius

How to Dispute Walmart Chargebacks

Not all chargebacks are valid. Walmart's automated systems issue fines without accounting for Walmart-side errors, weather events, or DC disruptions. Here's how to dispute:

•       Log in to Retail Link and navigate to the Accounts Payable Disputes Portal (for chargebacks) or the Supplier Dispute Portal (for deductions).
•       Submit disputes within 15–30 days of the chargeback posting date, depending on chargeback type.
•       OTIF-specific disputes are processed through HighRadius. Include HOST PO numbers, item numbers, and charge type amounts in your submission.
•       Walmart typically resolves disputes within 30–45 days.

A practical rule of thumb: if HighRadius rejects a dispute twice, the third attempt is generally your last opportunity. First-time suppliers receive a three-month grace period during which OTIF fines are waived.

Frequently Asked Questions

What is Walmart's OTIF compliance requirement?

OTIF (On-Time In-Full) requires prepaid suppliers to deliver 90% of cases on time and 95% of ordered cases in full. Missing these targets results in a 3% chargeback on the cost of non-compliant goods. Fines are assessed quarterly.

What happens if I miss Walmart's MABD?

If your shipment arrives outside your assigned delivery window, Walmart can issue an OTIF chargeback. MABD windows are one day for perishables and two days for general goods. Early deliveries are treated as non-compliant because Walmart DCs plan capacity tightly.

How do I access my Walmart compliance scorecard?

Log in to Retail Link and navigate to the SQEP Dashboard for labeling and PO accuracy data. For OTIF performance, go to the OTIF Scorecard within Retail Link. Both are updated on a regular cadence; OTIF data typically lags by one to two weeks.

Are FSMA 204 requirements already in effect for Walmart suppliers?

Yes. As of August 2025, Walmart requires all food and beverage suppliers to comply with FSMA 204 ASN and packaging requirements. Walmart expects suppliers to meet original compliance timelines even though the FDA extended the national deadline to 2028.

Can Walmart remove a supplier for repeated non-compliance?

Yes. Repeated supply chain failures can result in loss of shelf space, removal from the modular, or termination of the supplier relationship. Walmart has stated it is not interested in profiting from chargebacks, persistent non-compliance is viewed as an operational risk.

Conclusion

Walmart retail compliance is not optional. It is the price of entry for one of the most valuable retail relationships in the world. Meeting OTIF targets, maintaining SQEP standards, and keeping your EDI and ASN processes current are the three pillars of a sustainable Walmart supply chain strategy. The brands that treat compliance as an ongoing operational discipline and not a reactive chargeback fight, protect their margins and earn more shelf opportunities.
