EU RoHS Directive supplier change control workflow

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.

Also identify timing and inventory. Record the supplier's change-effective date, first changed lot or shipment, last known compliant lot, stock on hand, work in progress, products already placed on the market, service spares, and markets affected. A prospective supplier approval does not answer whether earlier or mixed inventory needs containment or a non-conformity assessment.

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.

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. A supplier declaration can identify those inputs, but the manufacturer still has to decide whether the changed BOM and finished EEE remain covered by the technical documentation.

A change to a manufacturing process matters only when it can change the finished EEE, its homogeneous materials, or the reliability and traceability of the evidence. RoHS does not restrict substances merely because they are used somewhere in production. Record the connection between the process change and the finished item before requiring new evidence or testing.

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.

Close only after the effective BOM revision and release date are approved, quarantined material has a disposition, the EU declaration remains accurate or has been updated, and the next trigger is assigned. If evidence is conditional, state the condition and expiry instead of recording an unconditional pass.
