Keep supplier declarations and test evidence traceable to the exact part, material, site, revision, substance conclusion, and finished China model. Supplier data supports, but does not replace, the product-level China RoHS decision. *Question* *China* ## What supplier evidence should we keep for China RoHS? Direct answer Keep supplier declarations and test evidence traceable to the exact part, material, manufacturing site, revision, substance conclusion, and finished China model. Supplier data supports the producer's or importer's product-level decision. The 2016 Measures do not prescribe a supplier declaration form or a general retention period. Keep technical support documents that connect supplier material declarations, test or analytical evidence where needed, bill-of-material links, change notices, gap reviews, and approvals to the exact China product model. ## Definitions ### China RoHS technical support documents **Term:** technical support documents Technical support documents are the traceable records that support a product's hazardous-substance control result, information disclosure, and marking. They can include supplier statements, raw-material and component test reports, supply-chain compliance evidence, bill-of-material mappings, assessment methods, product identifiers, and controlled approvals. **Why it matters here:** GB 26572-2025 makes technical-support-document requirements part of the mandatory national standard from 1 August 2027. The producer or importer still needs to connect supplier evidence to the exact finished product, China standard, catalogue status, exception, marking, and release decision.

Its value depends on the declared scope, product and site identifiers, revision, substances, limits, methods, exceptions, date, signatory, and supporting records. **Why it matters here:** This supply-chain record is not the same as the finished-product self-declaration used as one route under China's national conformity-assessment system. The responsible producer or importer must decide whether the supplier statement is sufficient for the product-level conclusion.

Map that evidence through the controlled bill of materials to the exact finished China model. A supplier declaration or EU RoHS document can be an input, but it does not establish the finished product's China marking, environmental protection use period, catalogue status, exception, or conformity-assessment conclusion. Treat the nationally recognised finished-product self-declaration as a separate conformity output. It is completed by the responsible producer for a catalogue product and supported by evidence such as raw-material or component reports and supply-chain compliance records; a component supplier's declaration does not replace it.

A signed declaration may be enough for a low-risk, well-characterised material when its scope and basis are clear. Seek more specific analytical or test support when the declaration is incomplete, the material is high risk, supplier controls are weak, the result conflicts with other data, or the applicable standard or conformity route requires it. Record the reason for accepting the evidence or escalating to testing. - Supplier legal name, manufacturing site, part number, and revision. - Material or test-unit mapping for each substance conclusion, at the level required by the applied limit or test method. - Declaration, test report, analytical method, laboratory identity, sample identity, date, result, applied standard, and any exception basis. - Finished-product bill-of-material revision and exact China model mapping. - Review of missing substances, ambiguous thresholds, expired exceptions, model mismatch, and conflicting evidence. - Approval owner, open gaps, supplier change-notification commitment, and refresh trigger.

Also reopen the record when incoming inspection, testing, or market feedback conflicts with the supplier's conclusion. From 1 January 2026 through 31 July 2027, catalogue-product conformity assessment may use GB/T 26572-2011 with Amendment 1 or GB 26572-2025. GB 26572-2025 becomes mandatory on 1 August 2027. The transition adds a concrete reason to check whether older supplier evidence covers the four added phthalates: DEHP, BBP, DBP, and DIBP.
