- [Certificates of conformity](https://planar.so/wiki/sourcing/documents/certificates-of-conformity.md): What conformity statements attest, how issuer and scope affect their meaning, and why declarations, test reports and third-party certificates differ.
- [Choosing an EN 10204 inspection document](https://planar.so/wiki/sourcing/documents/choosing-en-10204-inspection-documents.md): Compare 2.1, 2.2, 3.1 and 3.2 documents and specify the evidence needed for a material delivery.
- [Country-of-origin declarations](https://planar.so/wiki/sourcing/documents/country-of-origin-declarations.md): Statements of goods origin: preferential and marking purposes, issuer scope, supplier support, agreement-specific certification and validity limits.
- [EN 10204 type 2.1 documents](https://planar.so/wiki/sourcing/documents/en-10204-type-2-1-documents.md): Manufacturer declarations of compliance with an order: their scope, absence of test results, and distinction from test reports and inspection certificates.
- [EN 10204 type 2.2 documents](https://planar.so/wiki/sourcing/documents/en-10204-type-2-2-documents.md): Manufacturer test reports based on non-specific inspection: order compliance, test-result scope, distinctions from 2.1/3.1/3.2 and producer-specific additions.
- [EN 10204 type 3.1 certificates](https://planar.so/wiki/sourcing/documents/en-10204-type-3-1-certificates.md): Manufacturer-validated specific-inspection results, their product scope and the distinction between 3.1 and 3.2 documentation.
- [EN 10204 type 3.2 certificates](https://planar.so/wiki/sourcing/documents/en-10204-type-3-2-certificates.md): Specific inspection, joint validation, traceability and the limits of EN 10204 type 3.2 material certificates.
- [Material test reports](https://planar.so/wiki/sourcing/documents/material-test-reports.md): How reported material properties relate to product identity, test units, conditions, specifications and inspection-document validation.
- [Qualified manufacturers lists](https://planar.so/wiki/sourcing/documents/qualified-manufacturers-lists.md): Program-specific qualification evidence: governing specifications, facilities, technology flows, product scope, listing status and limits of manufacturer-wide claims.
- [Safety data sheets](https://planar.so/wiki/sourcing/documents/safety-data-sheets.md): Chemical hazard communication, product and jurisdiction scope, section meanings and the limits of composition or exposure information.
- [Supplier acknowledgments](https://planar.so/wiki/sourcing/documents/supplier-acknowledgments.md): Order receipt, business acceptance, proposed changes and the quantity/date scope of supplier responses.
