    Core-Mark EDI Requirements

    EDI: Mandatory Low chargeback risk6 documents

    Core-Mark requires every supplier to be EDI-compliant before going live. This page summarizes the documents typically exchanged, the chargeback profile, and how APIWORX automates compliance end-to-end.

    Required EDI Documents

    Chargeback Risk: Low

    Core-Mark has a relatively low chargeback profile compared to most large retailers. Compliance is still important — but penalties are less aggressive and more situational than at high-risk partners like Walmart or Target.
