Certification Documents You Can Check Before Paying a Deposit

 Certificate claims are the first thing Australian buyers ask a China factory to prove - so the full document pack goes out with the first quotation, not after the deposit. Three documents cover this model:

WaterMark Certificate of Conformity WMK26227, issued by SAI Global, current schedule valid to 10 July 2027. The schedule lists I-05 WHP by name - wall hung pan, rimless, P-trap, 4 stars - so you can verify the model on the SAI Global product schedule before ordering, rather than taking our word for it

Rough-In and Frame Compatibility: the Numbers Your Plumber Will Ask For

Dimension mismatches - wrong set-out, wrong frame, wrong outlet position - are the most common way wall hung orders go wrong on site. Check these against your frame supplier's spec sheet before ordering:

Fixing centres: 180 mm, the common standard for in-wall cistern frames sold in Australia.

Outlet: rear, Ø102 mm spigot, connection depth over 32 mm - within the 95–120 mm range AS 1172.1 requires.

Projection: 517 mm from the finished wall; ceramic body height 365 mm. Final seat height is set by the frame installation, not the pan.

Tested as a set: report A18019 tested this pan together with the G3004 concealed cistern (WaterMark licence WMKA21189, Xiamen R&T), so pan-and-cistern compatibility is documented, not assumed.

 

The 400 kg load safety result matters most on commercial jobs, where fixture loading is a structural sign-off item. Installation must comply with AS/NZS 3500.2 and be carried out by a licensed plumber; installation instructions and the compliance documents ship with every order.

Rimless Bowl and Glaze: What Factory QC Actually Checks

 

A rimless bowl has an open flush channel instead of a closed rim cavity. For housekeeping, that means no hidden rim to scrub. On the QC line, it means the flush pattern is fully visible during water testing - a blocked jet cannot hide under a rim.

For the buyers who never press play, here is what the video shows: in the test bay each pan is connected to a cistern and flushed with test media before packing.Pans that fail on flush coverage or trap seal are pulled off the line - they are not downgraded into export orders.
Glaze consistency across a container load comes from the firing, not the spraying. Pans are fired in a 126-metre tunnel kiln, 3.2 metres wide, alongside two 82-metre kilns; cross-section temperature in each zone is held even, which is why pan 300 in a batch shows the same colour and gloss as pan 1. The factory runs 309 casting lines with an annual output of about 3.5 million pieces, roughly 80% of it exported.

 

FAQ

Q: How do I verify the WaterMark certification for this model?

A: Check certificate WMK26227 on the SAI Global product schedule - I-05 WHP is listed by name - rimless, P-trap, 4 stars - valid to 10 July 2027. The certificate PDF and test report A18019 are also sent with every quotation, so verification takes minutes, not emails.

Q: Does this pan need an in-wall frame, and which cistern does it fit?

A: Yes - every wall hung toilet requires a load-rated in-wall frame with a concealed cistern; the pan itself passed the 400 kg load safety test. It was type-tested with the G3004 concealed cistern (WaterMark WMKA21189) and fits standard frames with 180 mm fixing centres.

Q: What are the MOQ

A: 20

Q: Can you produce under our brand?

A: Yes - OEM covers the logo badge on the ceramic, seat branding, carton print and colour-box design. Branded samples are produced for sign-off before the bulk run, and artwork files are kept on record for repeat orders.
