Sam's Club Supplier Compliance Guide

Sam's Club is one of the most technologically forward-thinking retailers in the United States, operating more than 600 warehouse club locations. As a division of Walmart Inc., Sam's Club benefits from significant supply chain infrastructure — but maintains its own distinct compliance requirements that differ meaningfully from Walmart's. For suppliers, understanding Sam's Club's unique compliance framework is essential to maintaining a compliant, profitable trading relationship.

This guide covers Sam's Club's key supplier compliance requirements, including their AI-powered exit technology, Supplier Item Data Excellence (SIDE) program, pallet standards, and the most common sources of chargebacks.

Sam's Club's Vendor Compliance Framework

Sam's Club manages supplier compliance through their vendor portal, which provides access to routing guides, compliance documentation, PO management, and performance reporting. All suppliers must maintain active access to the portal and stay current with compliance updates.

Sam's Club's compliance program reflects their investment in retail technology. Their Scan & Go and AI-powered exit systems create specific requirements for how products must be labeled and packaged to function correctly within their store technology infrastructure — going beyond traditional carton and pallet compliance into product-level design requirements.

AI Exit Technology and Scan & Go Requirements

Sam's Club has rolled out computer vision-based AI technology at store exits that identifies products in members' carts without requiring manual scanning. This technology places specific demands on product packaging and labeling that suppliers need to understand.

AI exit compatibility requirements:

• Primary packaging must have high-contrast graphics that allow AI cameras to identify the SKU from multiple angles while the product is in a cart
• Reflective or holographic foils on top-facing surfaces should be avoided, as they can interfere with AI sensor accuracy
• Barcodes must be placed accessibly for member Scan & Go scanning with a smartphone while the item is in the cart
• For large or bulky items, omni-directional barcodes or repeating barcode patterns on multiple faces are recommended

Suppliers launching new items at Sam's Club should review packaging designs with their Sam's Club buyer team to confirm AI exit compatibility before finalizing production.

Supplier Item Data Excellence (SIDE) Program

Sam's Club's SIDE program enforces accuracy in item data — specifically, the dimensions and weights recorded in their item management system must match the physical product within defined tolerances.

SIDE program requirements:

• Item weight and dimensions in the Sam's Club system must match actual product dimensions within a 10% tolerance
• Discrepancies beyond the 10% threshold trigger a compliance penalty: a flat fee per item plus per-location fees for affected stores
• For Direct-to-Consumer (DSV) orders, dimensions must match the shipping carton exactly to avoid incremental shipping expense chargebacks
• UPC/GTIN in the item system must match the barcode scanned by members via Scan & Go

Suppliers should audit their item data in the Sam's Club system at onboarding and periodically thereafter — particularly after packaging changes — to ensure dimensions and weights remain accurate.

Pallet Standards

Sam's Club has some of the most specific pallet requirements in retail, reflecting the need for pallets to be placed directly on the club floor for member shopping without additional processing.

Pallet requirements:

• Sam's Club requires 9-block (iGPS or CHEP) pallets only — standard stringer or GMA pallets are not accepted
• Standard 48" x 40" pallet dimensions required
• Total case weight must not exceed 50 lbs; cases over 50 lbs require a "Team Lift" label and buyer exception approval
• Pallets must be shoppable on at least two adjacent sides — labels and branding must face members on both sides
• No false bottoms or pallet skirts — packaging must be structurally sound and self-supporting
• Product must not overhang the pallet footprint

Pallet non-compliance at Sam's Club results in load rejection or restacking fees, which can be significant. Verifying pallet build quality before shipment is essential.

Labeling Requirements

Sam's Club requires GS1-compliant labeling on all cartons and pallets. Their labeling requirements are enforced through automated receiving and the SIDE program.

Carton and pallet label requirements:

• GS1-128 barcodes required on all shipping cartons
• Labels must meet Sam's Club print quality and placement requirements
• SSCC pallet labels required on two adjacent sides of each pallet
• ASN must be transmitted prior to shipment arrival, with SSCC numbers matching pallet labels exactly

ASN and EDI Requirements

Sam's Club requires EDI 856 ASN transmission prior to the shipment's arrival at their distribution centers. ASN accuracy and timing are strictly enforced with flat-fee chargebacks for violations.

ASN requirements:

• Must be transmitted after the shipment departs the vendor facility
• Must be received before the shipment arrives at the DC
• Carton and pallet contents must match the physical shipment exactly
• Late ASN transmission results in a per-occurrence chargeback

FSMA 204 and Traceability Requirements

For suppliers in high-risk food categories, Sam's Club is enforcing FDA FSMA Section 204 traceability requirements. Critical Tracking Events (CTEs) — including initial production and shipping events — must be documented and available digitally. For refrigerated goods, cold chain integrity documentation may be required to prevent spoilage chargebacks.

Common Sam's Club Chargebacks and How to Avoid Them

• Inaccurate item dimensions (SIDE): Dimension discrepancy over 10% — Prevention: audit item data at onboarding and after packaging changes
• Non-compliant pallet: Non-9-block pallet, overhang, or structural issues — Prevention: pallet inspection protocol before shipment
• ASN error: Late or inaccurate ASN — Prevention: automate ASN transmission via EDI integration
• Labeling error: Barcode defect or incorrect placement — Prevention: validate labels before shipment
• AI exit incompatibility: Packaging interferes with computer vision system — Prevention: review packaging with buyer team before production
