Every claim here carries a number

Ten documents in total. Five GB/T 17219 drinking water contact test reports, one for each water tank material, issued by the Dezhou Institute of Product Quality Standards and Metrology. Three management system certificates: ISO 9001 for quality, ISO 14001 for environment and ISO 45001 for occupational health and safety. A CE Verification of Conformity to EN 13280:2001. And an SGS supplier assessment covering the company itself. Each is shown on this page with its issuer, its number and its dates.

Take the number to the issuer, not to us. Drinking water reports can be checked with the Dezhou Institute of Product Quality Standards and Metrology. Management system certificates can be checked with the certification body named on the face of the certificate. ISO 9001 itself is published by ISO. We publish issuer, number and dates specifically so that verification does not require our cooperation.

It is the Chinese standard for the safety evaluation of materials and chemicals used in drinking water supply systems. Our current report covers twenty parameters and is run on the finished panel material rather than on a raw resin sample, which is the difference that matters when comparing suppliers. If the water your tank stores will be drunk, this is the document to ask for, not a general food-grade claim.

For potable contact, the usual references outside China are NSF/ANSI 61 in North America and the WRAS approval scheme in the United Kingdom. For galvanized coatings the reference is ISO 1461. We will tell you plainly where we hold a document and where we do not, rather than implying equivalence.

It is issued against EN 13280:2001, the European specification for glass fibre reinforced cisterns for cold water storage. It applies to the GRP/SMC range. As with every other document on this page, the certificate is shown with its number so a consultant can check the scope rather than take the mark at face value.

The company. It is a supplier assessment with an on-site check, which is why our Alibaba storefront is listed as a verified custom manufacturer rather than a trader. It speaks to who we are and what the factory can do; the GB/T 17219 reports and the CE document speak to what the water tanks are made of.

Yes. The versions on this page are for specification and comparison. For a tender, a consultant review or a fire authority submission we issue stamped copies addressed to a named person, sent as a complete set rather than one file at a time. Ask through the form on this page or the contact page and say which documents and which addressee.

The approved general arrangement drawing, the material certificates for the panels, the hydrostatic test sheet for your specific tank, the packing list and the relevant certificates. The test sheet is the one people forget to ask for: it records that your water tank held water at the factory before it was stripped and crated. All standing documents are downloadable from the datasheets and downloads page.

The page says so. Where a document is in renewal or not yet in our hands, it is shown as pending with the expected date rather than displayed as a badge. That is a deliberate choice: a register that only ever shows green is a register nobody can use to make a decision.

A certificate is the result; the work behind it is the inspection routine. Quality control is a separate department from production, panels are measured against the approved drawing rather than against the last batch, and every water tank is water tested before packing. You can follow that route on the factory tour and see how the departments are separated on the company structure page.

Yes. Each water tank is hydrostatically tested at the works and the test sheet for that specific water tank travels with it, alongside the material certificates and the approved drawing. The standing certifications on this page cover the company and the materials; the test sheet covers your water tank.

Each of the five GB/T 17219 drinking water reports covers one material, so between them they cover every range we build: GRP/FRP/SMC, stainless steel, hot-dip galvanized, enameled steel and BDF underground water tanks. The ISO management certificates cover the factory rather than a product, so they apply to all 65 models in the full catalogue.
