A folder of supplier declarations is not a RoHS technical file

The declarations are all in one folder, every supplier has ticked a RoHS box and the product is ready to ship. That conclusion can fail because component paperwork is only part of the evidence. The obligation sits with the economic operator placing the finished equipment on the market.

For Great Britain, official guidance requires in-scope electrical and electronic equipment to have supporting technical documentation and a Declaration of Conformity. Manufacturers, importers and distributors have different duties, but none can replace a product-level assessment with an unstructured archive of supplier PDFs.

Know which market and role apply

Great Britain and Northern Ireland do not use an identical framework. Start by recording where the equipment will be placed on the market and whether the organisation is acting as manufacturer, importer or distributor. Also record whether the product is in scope and whether any claimed exclusion or exemption actually covers the use.

UK guidance states that components sold business to business are not themselves placed on the market as finished electrical equipment for this purpose. Their material declarations remain useful evidence for the compliance assessment of the finished product.

Build a traceable evidence chain

Map the approved bill of materials to current supplier declarations, test reports or material data. Record the exact manufacturer part number and document revision. Flag declarations that cover a family without clearly identifying the ordered variant, or that rely on an exemption without stating its application.

The technical documentation should also explain the conformity assessment, production controls and how changes are reviewed. A declaration collected during prototype build can become stale after a supplier, finish, process or alternative part changes.

Control exemptions and changes

Great Britain operates its own RoHS exemption system, while Northern Ireland continues to follow the EU system. Teams selling into both markets should track the applicable exemption and expiry position separately. Do not assume that an EU decision automatically changes the Great Britain position.

A PCN, alternative component or manufacturing transfer should trigger a compliance impact check. That check may be brief when the evidence is clear, but the decision and supporting document should be linked to the product revision.

Make the file usable

• State the product, market, role and regulations assessed.
• Keep the Declaration of Conformity and assessment record together.
• Link every relied-on component document to an approved part and revision.
• Record exclusions, exemptions and the reasoning behind them.
• Define who reviews supplier and design changes.
• Retain the file for the required period and make it retrievable.

The commercial benefit is not paperwork for its own sake. A traceable file shortens customer questions, change reviews and regulatory responses because the evidence already explains how the product conclusion was reached.
