Certification
The paperwork, before you ask for it.
Four certificates and one test report, all downloadable below. The numbers from the test report are also written out in English further down this page — a four-page scan in Chinese is no use when you are comparing three suppliers at midnight.
The certificates sit with three companies in the same group: Guangzhou (cUPC listing), Guangdong (green building, test reports) and Yunfu (NSF, management systems, manufacturing). The quotation is issued by the exporting entity — tell us which one you need on the invoice and we will match the paperwork to it.

Management systems
ISO 9001, 14001 and 45001.
The Yunfu plant has held certification to ISO 9001, ISO 14001 and ISO 45001. Copies of the current documents are supplied with a quotation on request.
These three are not published here as downloads. The previous certificate cycle ran to April 2026 and the renewal copies are with the certification body, so we would rather send you the current document than show you a date we cannot stand behind.

What we cannot give you
The certificates we do not have.
No CE marking, no Greenguard, no SABER or ECAS registration held in our own name. If your project needs one of them, tell us at quotation stage and we will say whether it can be obtained, how long it takes and who pays for it — rather than discover it while your container sits at the port.
The cUPC listing above covers sinks and lavatories, not slabs. Anyone who shows you a cUPC certificate as proof that a quartz slab is certified is showing you the wrong document.
