# Supplier Declarations and Verification

A practical supplier evidence playbook for EU RoHS Directive 2011/65/EU.

*Suppliers* *Evidence*

## EU RoHS Directive (2011/65/EU) Supplier Declarations and Verification

Declarations are a control, not a checkbox.

Output: supplier requirements + test triggers + evidence vault links per part and homogeneous material.

RoHS compliance is only as strong as your supplier evidence. The goal is not to collect a PDF, but to maintain a defensible chain of proof: where restricted substances could exist, why they do not exceed thresholds or are exempt, and how changes are controlled.

## What to request from suppliers (minimum viable RoHS evidence)

Request evidence that maps to the RoHS unit of control: homogeneous materials.

Avoid generic declarations that do not identify which parts or materials they cover.

- Annex II substances declaration (all 10 substances) with statement of homogeneous material coverage
- Exemptions disclosure: which exemption (exact wording) is relied upon, for which application/material
- Material and process disclosure for hotspots: solders, platings, cable insulation, soft plastics, pigments
- Change notification obligation: formulation, plating chemistry, resin system, or supplier chain changes must be disclosed
- Document-control fields: supplier version, date, signer authority, and covered manufacturing site

*Recommended next step*

*Placement: after the template, evidence, or documentation block*

## Keep EU RoHS Directive (2011/65/EU) Supplier Declarations and Verification in one governed evidence system

SSOT can take EU RoHS Directive (2011/65/EU) Supplier Declarations and Verification from reusing this material inside a governed evidence system to a reusable workflow inside Sorena. Teams working on EU RoHS Directive (2011/65/EU) can keep owners, evidence, and next steps aligned without copying this guide into separate documents.

- [Open SSOT for EU RoHS Directive (2011/65/EU) Supplier Declarations and Verification](/solutions/ssot.md): Start from EU RoHS Directive (2011/65/EU) Supplier Declarations and Verification and keep documents, evidence, and control records in one governed system.
- [Talk through EU RoHS Directive (2011/65/EU)](/contact.md): Review your current process, evidence gaps, and next steps for EU RoHS Directive (2011/65/EU) Supplier Declarations and Verification.

## Evidence tiers (how to scale across thousands of BOM lines)

Not every part needs the same evidence depth. Use tiers to scale: low risk gets declarations; high risk gets verification.

Define tier rules and make them part of procurement onboarding.

- Tier 1 (low risk): declaration + supplier change control + periodic refresh
- Tier 2 (medium risk): declaration + material composition detail + targeted verification triggers
- Tier 3 (high risk): declaration + test reports or verified material data + lot/batch traceability where feasible
- High-risk flags: soft plastics (phthalates), legacy polymers (brominated FR), solders/terminations (lead), platings (Cr(VI))

## Risk-based testing strategy (verification triggers)

Testing is expensive; the right strategy is trigger-based and targeted to hotspots.

Use testing to validate the supplier system and to catch changes, not to test every component forever.

- Trigger tests on: new supplier, formulation change, process change, contradictory declarations, or new high-risk material
- Target homogeneous materials, not assemblies (e.g., cable insulation polymer, solder alloy, plating layer)
- Define actions on failure: quarantine, supplier corrective action, requalification, redesign, and customer impact assessment
- Keep test evidence linked to the exact part/homogeneous material and time window

## Change control (the control that prevents 'silent non-compliance')

The hardest RoHS failures are silent supplier changes: a resin system changes, a plating line changes, a sub-tier supplier changes.

Solve this with contractual duty + operational monitoring + sample verification.

- Contract clause: mandatory advance notice for material/process/supplier chain changes
- Operational process: change intake -> risk review -> evidence update -> release approval
- Monitoring: periodic declaration refresh and selective verification sampling
- Traceability: map supplier changes to affected SKUs and production lots where possible

## How to store evidence (EN IEC 63000 mindset)

Your evidence vault should match the RoHS documentation standard: organise evidence by product family/variant and link supplier artifacts at the right granularity.

If you can't retrieve evidence quickly, you can't defend compliance.

- Evidence index: product -> part -> homogeneous material -> supplier -> evidence artifact
- Store: declarations, exemptions register entries, test reports, and change logs
- Define a review cadence (quarterly for high-risk parts; annual for low-risk)
- Make evidence creation a release gate (no new supplier/part without evidence)
- Retain the documentation so the manufacturer and importer can satisfy their 10 year document duties
