Certificates & how to verify them

We publish our certificate numbers because we tell buyers not to trust a typeset PDF. The three management-system certificates below carry the CNAS and IAF-MRA accreditation marks and are verifiable by registration number in the issuing body's register and on the CNCA national portal. The registered legal entity on the certificates is “Zhejiang Sanli Pipeline Technology Co., Ltd.” (Social Credit Code 913306817377675138) — the former company name still shown on these documents.

Scope of certification (all three): Sales & service of stainless steel water collectors and valves; production of water-heating pipes including PE-Xa & PE-Xb cross-linked polyethylene pipes, PE-RT underfloor-heating pipes, aluminium-plastic composite pipes and plastic fittings (excluding items requiring a hygiene permit).

Product conformity — EAC, CE, SKZ

SANLI pipes also carry CE and SKZ marking for European requirements and EAC conformity for the EAEU market. These are product-level documents issued per product, batch or order, so we supply the specific number with your shipment rather than posting a fixed list here. You can verify each in the relevant public register: EAC in the unified EAEU registry (pub.fsa.gov.ru), a CE notified body by its four-digit number in EU NANDO, and an SKZ report by report number on the institute's site.
