It publishes no OpenAPI, no OAuth surface and no API-protocol conformance claims, so the API-side conformance list is empty rather than invented. What it does publish, on its customer resources pages, is third-party chain-of-custody and recycled-content certification for the physical product — the compliance regime that actually governs its market. Those are recorded here with the exact page that carries each claim. api_conformance: [] api_conformance_note: >- No machine-readable contract exists to assert oauth2, oidc, odata, json:api, rfc9457, pagination or idempotency conformance against. The one unauthenticated JSON surface on a graphicpkg.com host (the careers job query API) is operated by the AppVault career-site platform, uses a bespoke {"error": "..."} envelope rather than RFC 9457, and publishes no conformance statement of its own. domain_standards: - id: fsc-chain-of-custody name: FSC Chain of Custody (Forest Stewardship Council) conforms: true kind: product-certification evidence: https://www.graphicpkg.com/customer-resources/fsc-chain-of-custody-certification/ http_status: 200 - id: pefc-chain-of-custody name: PEFC Chain of Custody (Programme for the Endorsement of Forest Certification) conforms: true kind: product-certification evidence: https://www.graphicpkg.com/customer-resources/pefc-chain-of-custody-certification/ http_status: 200 - id: rpa-recycled-content name: RPA (Recycled Paperboard Alliance) recycled content certification conforms: true kind: product-certification evidence: https://www.graphicpkg.com/customer-resources/rpa-certification/ http_status: 200 regulatory: - id: eu-ppwr name: EU Packaging and Packaging Waste Regulation (PPWR) conforms: null kind: regulatory-regime note: >- Graphic Packaging writes about PPWR readiness on its own blog but publishes no conformance statement, so this is recorded as a regime it operates under, not as a claim. evidence: https://www.graphicpkg.com/resources/unwrapping-ppwr-legislation-whats-next-for-food-packaging/ http_status: 200
