with the self declaration.
Amazon did not accept my self-declaration. They simply moved the goalposts and said I must provide certification.
I am currently researching and so far, it appears to me, on reading through REACH (yawn) that jewellery is considered to be an ARTICLE and not a preparation or substance. ARTICLES are not required to be certified by REACH, according to Article 33 of REACH for jewellery.
I am going to send this to Amazon tomorrow.
