Exporting fixtures into Australia requires you to be certified under WaterMark. This is a national certification scheme that verifies plumbing products are safe to install and meet the Australian building code. Other things you’ll need include the right AS/NZS testing standard, lead-free brass, and a supplier whose license you’ve actually checked yourself rather than taken on faith.
What Is the WaterMark Certification Scheme, and Why Should You Care?
WaterMark is Australia’s mandatory national certification scheme, administered by the Australian Building Codes Board (ABCB). It ensures that plumbing and drainage products covered by the scheme are safe, fit for purpose, and compatible with Australian requirements.
In practice, this means a licensed plumber generally cannot legally install a plumbing fixture that does not have the required certification. Installing non-compliant products may put their professional license and liability coverage at risk.
So a shipment of uncertified WaterMark faucets is more than a compliance risk. Once imported, these products may face difficulties being installed by licensed plumbers or accepted for regulated projects.
Getting from raw product to legal import looks like this:
Product Sourcing → Accredited Lab Testing → WMCB Evaluation → License Issued → Legal AU Import
If a factory has skipped a step anywhere along that chain, the shipment breaks somewhere between your warehouse and the job site, usually at the worst possible time.
What Happens If Your Faucets Are Not Certified?
Importing plumbing fixtures without a valid certificate can lead to severe consequences.
First, Australian customs officers will seize your shipment at the border. Second, licensed local plumbers will refuse to install the products because they could lose their plumbing licenses.
Finally, if an uncertified faucet leaks and floods a building, insurance companies will not pay for the water damage. Buying certified WaterMark faucets from the start prevents these border delays, satisfies local installers, and protects your business from expensive lawsuits.
Plumbing Categories and Testing Rules
Certification is not the same for every product. Each type of faucet must pass different safety tests before it can be sold in Australia.
For example, Watermark kitchen faucets must have lead-free brass pathways and ceramic cartridges rated for constant use and high pressure. These are tested under the Australian standard called AS/NZS 3718. If you’re sourcing for a hotel kitchen or a busy commercial space, this is the standard your supplier has to hit.
Bathroom fixtures get tested a bit differently. High-density residential builds and hotels need watermarked bathroom faucets that survive hundreds of thousands of open-close cycles without leaking. This is done in accordance with the AS/NZS 3718 standard.
Whether you’re ordering matte black mixers or touchless sensor taps for public washrooms, check the specific model against the registry before you place the order.
Showers sit in their own category because of thermal risk. A watermark shower faucet needs internal mixing valves that prevent sudden temperature spikes or scalding. This gets tested under its own standard called AS/NZS 3662 and is separate from the one used for kitchen and bathroom taps.
What the Lab Actually Tests For
Every watermark tap has to pass a set of independent lab tests before it earns certification. Knowing what’s actually measured helps you ask your factory better questions.
| What’s Tested | What It Checks | Standard |
| Material Toxicity | No heavy metal leaching into drinking water | AS/NZS 4020 |
| Lead Content | Capped at 0.25% weighted average | Lead Free Law |
| Hydrostatic Strength | Resists high-pressure bursts and leaks | AS/NZS 3718 |
| Water Efficiency | Flow rate, for WELS star ratings | WELS Scheme |
The lead threshold isn’t negotiable. A watermarked faucet made from traditional high lead brass simply can’t be installed in Australia.
If a factory quotes you standard brass without confirming a lead-free alloy, ask more questions before signing anything.
Details Most OEM Agreements Overlook
Having a certificate on file at the factory isn’t the same as having a compliant shipment, and a few specific gaps catch importers more than anything else.
Physical marking is one. The “W” logo, the license number, and the relevant standard code need to be laser-etched or stamped directly onto the fixture itself, not printed on the retail box. A shipment that shows up with only a sticker or packaging print will get refused on sight by a plumbing contractor, and you’re the one left explaining it to your customer.
Scope of Use documentation is another. Every certified fixture needs a printed statement defining exactly where and how it’s approved to be used, included in the box or manual. It’s a small insert, but its absence is enough to make a product legally unsellable.
Brand alignment trips up private label buyers especially. If you’re branding an OEM product under your own name, that name has to be added as an “Approved User” on the factory’s certificate through their Conformity Assessment Body. Customs checks the public registry, not your invoice, so if your brand isn’t formally linked to the certificate, that mismatch alone can hold up the shipment.

View ProductThere are two real paths here, and each has a trade-off.
Domestic OEM distributors offer immediate Australian stock and lower minimum orders, but at a higher price per unit. Offshore manufacturers give you better margins and room for custom branding, but only if you do the legwork first.
That means getting the factory’s Certificate of Conformity number and checking it yourself against the official ABCB WaterMark Product Database, confirming model numbers and lead-free designations match exactly before any deposit changes hands.
This is really where the manufacturing partner matters. A factory that handles its own faucet design and mold development in-house can trace brass composition, thread specification, and certification paperwork all the way from the first mold to the finished container. A trading intermediary usually can’t back any of that up with the same confidence, since they’re a step removed from the actual production line.
A Quick Checklist Before You Commit
Before you sign off on an order, run through this:
- Ask for the active license number and certificate, then verify it yourself on the ABCB portal rather than trusting a screenshot
- Confirm the lead content sits under 0.25%
- Check that the flow rate is registered under WELS
- Physically inspect a sample for the permanent markings on the fixture itself, not the box
- Look over the packaging to make sure WELS ratings and registration details are printed where they’re supposed to be
Skipping even one of these is usually how a shipment ends up stuck at a port instead of on a job site. Get it right once, build the relationship with a verified supplier, and sourcing WaterMark faucets for your next order gets a lot easier than the first one.
