View Full Version : RoHS Compliant Declaration - General or Detailed?

I have a very simple question.
We are asking our suppliers to provide us with a Declaration of Compliance with ROHS.

Is it sufficient for the supplier to make a GENERAL declaration that his component/material is “ROHS complaint”; or do we require a more DETAILED declaration, e.g. “samples of the product were tested and found to be within the limits specified in the Table below”:

Lead (Pb): 0.1% by weight
Mercury (Hg): 0.1% by weight
Cadmium (Cd): 0.01% by weight
Hexavalent Chromium (Cr-VI): 0.1% by weight
Polybrominated Biphenyls (PBB): 0.1% by weight
Polybrominated Diphenyl Ethers (PBDE): 0.1% by weight

Thanks.

Here is an example of a form that might be of some use to you.

My standard approach is to send out a single statement that says that all of our parts are RoHS compliant. We hired a consultant to come in and verify this so we have back up.
This may not work for every company as other's RoHS compliance may be more part/product specific.

In a few instances we've had customers send us a specific form to complete and send back. These are not common though. Most are satisfied with the simple statement.

We have a standard form that we send whenever we have a request. The form has two boxes. You tick box A if it complies within the stated tolerance limits and then simply sign. OR you tick box B which states that the part does not comply and allows you to break the substances of concern down and where they exist within the part.

So I suppose that equates to a flexible form that contains within it the option to make a simple declaration.

However, we are subject to more than one regulation (ELV as well) and therefore it has to be flexible.

Whether the declaration is general or detailed, it’s the same. They are collectively termed as Self-Declaration.

Self-declaration applies to organizations whose products are covered by the RoHS directive and are able to demonstrate that they comply. To support it, you need to maintain a technical construction file (TCF) which records your reasons and decisions and all other supporting documents such as material declarations for each component or sub-component and any relevant test results, etc. In addition, you need to check RoHS compliance for the plastic, paint and surface finishes or plating.

If my liabilities are high, I would like to check the details. I’ve seen organizations (in my country) that simply copied another’s declaration note and declare that they comply – without going into the testing stage to investigate and/or confirm that their products are in compliance.

I would also consider before I send a certificate of RohS conformance, how do I know that my product is RohS compliant.

Lead is commonly used in electronics and alloys. Plating with Hexavalent chromium is a very common rust inhibitor.

Signing a certificate of conformance without having information from your suppliers might be a risk you should consider.

I agree with Harry. It is more than signing a CofC. You have to understand your supply chain and your internal processes from a substance aspect.
