Recently, there is new enviromnetal protection law published in USA, which pointed at the lead content of apparel and textile to be less than 300ppm.
Considering about US law's requirement, a new hot fix production occur. Lead free hot fix rhinestones, as for crystal, its lead content is less than 300ppm, but for some colored one, such as Siam, black, it is hard to control the lead content in the rhinestones, so they are not up to the request of Law.
But for hot fix rhinestuds(octagon) and hot fix nailheads, they are both lead free, the lead content of them are less than 300ppm, whihc have passed SGS and ITS inspection. Because the material of hot fix rhinestuds and nailheads are aluminum and glue,both of them contains such limited lead.
Enviromental protection is a long work, new technology can surley bring new prodution without pollution.
