When our factory started making toilet block in 2003, the quality was unstable and serious consequences occurred. After certified by ISO 9001:2008 and ISO9001:2015 quality Authorization, we began to rectify and reform on the whole production process and quality control. Semi-product should be packed after the test finished in 48 hours to ensure no unqualified product rollout and 100% guarantee quality. We also have the SGS test report and FDA certificate.
