Verify This Shower Head Factory: Identification and Audit

The identifiers, and how to check them

The Unified Social Credit Code is the registration number every company in China carries. It is printed on the business license, and it is the one identifier that ties a website, a quotation and an export document to the same legal entity. ZHONGHE's code is 91330282726386942E. Ask for a copy of the business license, check that the code and the legal name match, and then check that the same legal name appears on the proforma invoice, the sales contract and the shipping documents.

The address should survive the same test. No.3 Jiangxi Road, Cangbei Village, Changhe Town, Cixi, Ningbo, Zhejiang 315318 is the operating address; the business licence records the registered address as Cangbei Village, Changhe Town, Cixi. On a video call, ask to see the gate, the molding shop and the assembly lines in one continuous walk rather than a set of clips, and ask the person on camera to say the date. Confirmed by the owner on 2026-10-09: all 96 models currently listed in the global-site catalog are produced at ZHONGHE's own factory; new molds are made by external toolmakers. Tool ownership, charges and exclusive-use terms are agreed per project.

What the factory shares before an order

A copy of the business license with the legal name and the registration code; factory photos and video of molding, assembly, water testing and packing; the model list with the 96 catalog codes; a sample of the model under discussion; a quotation issued in the legal name, with the port of loading and the Incoterms; packing details with carton dimensions and weights; and the test description for the product, meaning what is tested on every unit and what is tested by sampling.

What is not shared: other buyers' designs, artwork, prices or programs. A supplier that hands over another customer's file to win your order will hand over yours to win the next one.

Ways to verify without traveling

A live video walkthrough is the fastest check. Ask to see the molding machines running, parts moving to a line, the water test in use, and the rework area. Ask the questions while the camera is moving rather than sending them in advance.

A sample is the second check. Order the exact model and finish you plan to buy, and test it the way the guide linked below describes: hold pressure, measure flow at a stated pressure, cycle the modes, check the thread and the finish. A sample that arrives with no model code and no packaging is a warning on its own.

A small trial order is the third. It shows how the supplier handles artwork, packing, documents and a schedule, at a scale where a mistake is cheap. ZHONGHE's OEM MOQ of 500 to 2,000 units is set with exactly this kind of first order in mind.

Third-party audit and inspection

Third-party inspection agencies are welcome at pre-shipment, and a wider factory audit in the style of the international agencies can be arranged for a project. Tell the factory which agency, which audit protocol and which dates, so the visit can be scheduled against a real production day rather than an empty one.

On certificates, the position on this site is deliberately plain: ZHONGHE does not assert certifications it cannot show. Certified options and test reports are arranged per project, with the standard, the scope and the test house named in the quotation. If a supplier's website claims a certificate without a number, a scope and an issuing body, treat the claim as unverified until you see the document.

Check each claim against a record you can open

A supplier's claims are only as good as the record behind them, so check each one where it is kept rather than on the supplier's own page. ZHONGHE's records are set out below the way a buyer would check any factory: the registration in China's official company register, the ISO 9001 certificate on the certification body's own lookup, the registration records of its designs, and the commercial terms it states in writing.

Two cautions apply to every factory, this one included. A test report proves only what it tested: read the full original, check the sample description, the standard and the date, and note who submitted the sample. ZHONGHE's filter-media data, for example, comes from the media supplier's reports and describes the media, not a finished shower head. And lead times and order quantities are references, not guarantees: ask for them in the quotation for your exact model, finish and packaging.

Original factory documents available for review

The company records page publishes the ISO 9001 certificate No. 02426Q00147R001, Intertek WCA Award F_IAR_224592_WCA and the records of Chinese appearance-design registrations. Each record has a number, issuer, printed dates and scope. the issuer's online lookup showed the ISO certificate as valid on 2026-10-14; WCA concerns workplace conditions; design records concern appearance and do not certify product performance.
