Our ISO certifications ensure peace of mind by giving you the assurance that every bag you purchase, can be traced from cradle to grave. Over and above the normal Cadmium (Cd), Lead (Pb), Mercury (Hg), Arsenic (As), Cobalt (Co), Chromium (Cr), Nickel (Ni) and Selenium (Se) analysis required by law, we do Dioxin, Melamine and Salmonella testing on demand.
