EU RoHS Directive supplier change control workflow

Supplier changes can affect RoHS evidence when they alter materials, components, coatings, solder, cables, exemptions, test coverage, manufacturing processes, or the traceability behind the technical file.

Use this workflow to decide when a supplier change needs new declarations, deeper material evidence, targeted testing, exemption review, or a manufacturer technical-file and EU DoC update.

Overview

A RoHS supplier change control workflow should protect the finished electrical or electronic equipment evidence file, not just collect another supplier certificate. Directive 2011/65/EU requires manufacturers to keep technical documentation and the EU Declaration of Conformity for 10 years, maintain procedures so series production remains in conformity, and adequately account for changes in product design, characteristics, harmonised standards, or technical specifications. Supplier evidence supports that assessment, but it does not supersede the manufacturer's Article 7, Article 13, and CE marking duties.

Section 1

Supplier changes that should reopen the RoHS review

Reopen the RoHS review when a supplier change can affect the substances, homogeneous materials, exemptions, traceability, or technical-documentation basis used for the finished EEE. The trigger is not limited to a new legal entity; a process, site, sub-tier, finish, coating, resin, solder, cable, or BOM revision can also change the evidence behind a RoHS conclusion.

The first decision is whether the changed item is part of finished EEE, a component supplied for integration, a separately placed-on-the-market EEE, a cable, or a spare part. The Commission FAQ explains that components used in finished EEE must meet the substance restrictions, but components for integration do not necessarily need their own RoHS CE marking or Declaration of Conformity when covered by the finished EEE context.

Open a review for supplier substitutions, part-number or revision changes, material or finish changes, manufacturing-site moves, sub-tier supplier changes, exemption reliance, old declarations, unknown substance coverage, or a new harmonised-standard basis.
Classify the changed item by role and use: finished EEE, component for integration, internal wiring, external cable supplied with EEE, separately marketed cable, spare part, or material input.
Check whether the change affects a homogeneous material because RoHS maximum concentration values apply by weight in homogeneous materials, not to the finished product averaged as a whole.
Do not close the review with a generic supplier statement if the statement does not identify the affected item, revision, substance scope, evidence basis, date, and signer.

Section 2

RoHS supplier change control workflow

Use the workflow as a release gate for the affected BOM line and for any finished EEE that depends on it. The goal is a documented accept, reject, test, or escalate decision that can be traced to the technical file.

Keep supplier declarations in the evidence pack, but make the internal decision explicit. Under RoHS, the manufacturer draws up the technical documentation, carries out internal production control, draws up the EU Declaration of Conformity when compliance is demonstrated, and affixes CE marking to finished EEE before placing it on the market.

1. Intake the change: record supplier, part number, customer part number, revision, material or process change, affected products, first shipment date, and whether old inventory remains in use.
2. Scope the item: decide whether the changed item is finished EEE or an input to finished EEE, and identify the homogeneous materials or constituent parts affected.
3. Collect evidence: request a current declaration, substance matrix, material declaration, exemption statement, test report where available, and change notice that names the affected item and revision.
4. Review evidence quality: confirm coverage for the current Annex II substance list, the right part revision, any claimed Annex III or IV exemption, and the method used for assessment or testing.
5. Decide the control: accept the supplier evidence, accept with limits, require targeted testing, require supplier clarification, update the exemption register, quarantine material, or block release.
6. Update the manufacturer file: revise the BOM evidence index, EN IEC 63000 assessment note, test plan, exemption record, EU DoC support file, and review trigger before closing the change.

Section 3

Evidence acceptance rules for supplier changes

Supplier evidence is strongest when it is current, item-specific, revision-specific, and tied to the substance restrictions or an applicable exemption. A one-line 'RoHS compliant' certificate is usually too weak for a material or supplier change unless other controlled evidence already supports the same conclusion.

Article 16 supports a presumption of conformity for materials, components, and EEE when tests and measurements demonstrate compliance with Article 4 or when assessment follows harmonised standards whose references are published in the Official Journal. That makes supplier declarations useful inputs, but the technical-file owner still needs to judge whether the evidence is enough for the changed BOM and finished EEE.

Accept supplier evidence only for the parts, revisions, materials, sites, and dates it actually names.
Escalate declarations that omit phthalates, identify no evidence basis, rely on expired or unclear exemptions, or conflict with test reports or material declarations.
Use targeted testing or deeper material documentation when the changed material has higher RoHS risk, the supplier is new, the process changed, the evidence is stale, or market-surveillance exposure is material.
Record why no new testing was needed when the team relies on declarations, material data, prior test history, or an EN IEC 63000-style assessment instead of new laboratory analysis.

Section 4

Records to close the workflow

Close the workflow only when the change record shows what changed, what evidence was reviewed, what decision was made, and what finished EEE files were updated. The record should be usable by procurement, quality, engineering, regulatory, and support teams without reconstructing the history from email.

Keep the closure packet connected to the manufacturer technical documentation and EU DoC support file. Directive 2011/65/EU requires manufacturers to retain technical documentation and the EU Declaration of Conformity for 10 years after the EEE is placed on the market, and importers must keep a copy of the EU DoC for the same period while ensuring technical documentation can be made available on request.

Store the supplier change notice, revised declaration, material or test evidence, independent review note, affected BOM list, decision status, and next review trigger.
Update the exemption register when a supplier change introduces, removes, narrows, or changes reliance on an Annex III or Annex IV exemption.
Update the non-conforming EEE or recall register if the change reveals released product that may not meet Article 4 requirements.
Keep traceability to economic operators in the supply chain so market-surveillance requests can be answered for the required retention period.
