What a buyer asks for
Walmart asks its food suppliers to share lot or batch codes, date codes, and where each lot code was generated, and to send an advance ship notice with traceability data for every delivery, linked to the pallet’s SSCC label.
A buying network can ask for more than the legal minimum. Suppliers need to know exactly which identifiers and handoff data travel with each shipment.
