I have a customer who now wants certificates that state that there are no prohibited materials in our products. They list pure cad, pure zinc and pure tin as the culprits. They also want a certificate stating that there are no counterfeit parts and materials present in their deliverable product.
Does anyone have a copy of such certifications that I could look at to get a feel for what they want?

I've been getting a lot of those type of requests too. A recent one was similar to yours - try going to toxicsinpackaging dot org. (I'm a first-time poster so it won't actually let me post the link. However, it's all one word then the dot org.) On their site, they have a sample certificate of compliance. That might get you started. Good luck.

They also want a certificate stating that there are no counterfeit parts and materials present in their deliverable product. Counterfeit of parts, especially eletronic components is a big (and growing) problem in the aviation, space and defense sectors. An AS standard (AS5553) has just been released by SAE.
How can you ensure that there are no counterfeit parts in your product? Depending on the product and your supply chain, it could be a daunting task to ensure that only legitimate components exist.

Against which directive or law the substances are prohibited ? I did not hear about pure Sn as prohibited ?? We do have a lot of requirements nowadays concerning hazardous material, (RoHS, REACH etc) ... and lists of substances (and their limits!) are available. For RoHS substances, you can require a certificate to a third party testing (like SGS report), where they know against which standard they have to test and the authorized limits.

For counterfeit parts, I can not help, sorry
