WaterMark & Lead Free: What to Check When Sourcing Plumbing Products from China to Australia

If you are buying bathroom or plumbing products from China for your home in Australia, there is something important you need to check before placing the order:

WaterMark certification.

For some products, you may also need to check Lead Free (LF) requirements.

WaterMark is not only about taps. Different plumbing and drainage products may have different requirements in Australia.

Recently, I had a small issue with Lead Free certification in one of my Australian home projects.

We actually knew about the requirement from the beginning, and I had already told the supplier clearly before placing the order.

But when we checked the certification again later, we still found a problem.

I think this is a good real example to share.

What is WaterMark?

WaterMark is an Australian certification scheme for certain plumbing and drainage products.

If a product is covered by the mandatory WaterMark requirements, it needs the correct certification for use in Australia.

But not every bathroom or plumbing product has the same requirement.

So when sourcing from China, I don't think it is enough to simply ask a supplier:

"Do you have WaterMark?"

The more important question is:

Does the certification cover the exact product and model we are buying?

A supplier may have WaterMark certification for some products, but that does not automatically mean every product they sell is covered.

This is something I always want to check carefully.

f you want to check a WaterMark certification yourself, you can use the official Australian WaterMark Product Database. You can search by licence number, brand, product model or product type to see whether the product is listed.

What is Lead Free (LF)?

Lead Free is another requirement that applies to certain plumbing products and materials in Australia.

For products where the Lead Free requirement applies, the weighted average lead content of the surfaces in contact with drinking water must not be more than 0.25%.

WaterMark and Lead Free are related, but they are not exactly the same thing.

Having WaterMark does not automatically mean a product also meets the applicable Lead Free requirement.

At the same time, this does not mean that every product requiring WaterMark also requires LF.

It depends on the specific product and its use.

If there is any doubt, I always prefer to check before ordering.

Why Can the 2026 Lead Free Rules Be Confusing?

This part can be a little confusing.

Australia moved into a new stage of its Lead Free requirements from 1 May 2026.

At the same time, there are national transition arrangements for certain products already in the supply chain.

So when you search online, you may see both:

1 May 2026

and

1 May 2028.

This can be confusing for homeowners, and sometimes even for suppliers.

This is why I don't think we should look at only one date and assume that a product is okay to use.

The product itself matters.

The state where your project is located also matters.

Victoria is Different

My client's project is in Victoria.

Victoria did not follow the extended national transition period for the relevant Lead Free requirements and kept 1 May 2026 as the commencement date.

So for a project in Melbourne or other parts of Victoria, this is something that needs to be checked carefully.

Of course, the exact requirement still depends on the particular product and installation.

For final installation requirements, I always recommend checking with your licensed plumber in Australia.

What Happened in My Project?

This is what happened in my Australian project.

From the beginning, my client clearly told us that the relevant taps needed WaterMark + LF for their project.

I also clearly gave this requirement to the supplier before ordering.

The salesperson confirmed it.

So at that point, everything looked fine.

But later, when we checked the certification information again, we found that:

Three of the taps had WaterMark, but they did not have the LF required for my client's project.

I immediately went back to the supplier and checked again.

It turned out that the salesperson had misunderstood the latest transition rules.

She thought the existing WaterMark was still okay.

But this project is in Victoria.

My client checked the local requirement again and confirmed that they needed LF for these taps.

So finally, we cancelled the three taps without LF.

Luckily, we found the problem before shipping.

A Supplier Saying "Yes" is Not Always Enough

When a supplier says a product has WaterMark, I normally ask for the WaterMark licence number and the exact product model.

Even if the supplier does not provide a copy of the certificate, you can still check the product through the official Australian WaterMark Product Database.

The important thing is not just whether the supplier has WaterMark certification, but whether the exact model you are buying is covered by that certification."The supplier said yes."

The Exact Model Matters

A supplier may have many different products and models.

They may have WaterMark certification, but this does not automatically mean every model they sell is covered.

So when my Australian clients have specific certification requirements, I will normally ask the supplier for the available information, such as:

• WaterMark certification information

• Certificate or licence number

• Product and model information

• Lead Free information if required for the project

• Photos of the relevant markings on the actual product, where applicable

The important thing is to make sure the certification information matches what we are actually buying.

If anything is unclear, I prefer the client to double-check with their licensed plumber before we place the order.

Can You Still Buy Bathroom and Plumbing Products from China for Australia?

Yes, of course.

There are many good suppliers in China, with a lot of choices in design, finish, material and price.

But for an Australian project, I don't recommend looking only at:

Design + Price

You also need to think about whether the product is suitable for your project and what certification may be required.

For me, the process should be:

Choose the Product → Confirm the Specification → Check Project Requirements → Check Certification → Confirm the Model → Order → Follow Production → QC → Shipping

Finding a beautiful product is not difficult.

Making sure it works for your actual project is more important.

How I Help My Clients

I help overseas homeowners source furniture and home products from China, including furniture, custom cabinetry, lighting, bathroom products, tiles, stone, curtains and other home materials.

For Australian projects, if WaterMark, Lead Free or another local requirement is important, I can help communicate the requirement with the supplier, collect the available certification information, check the product and model, follow production, arrange QC and check the actual products before shipping.

But I am not an Australian plumber or certification authority.

For the final compliance and installation of a specific product, I always recommend checking the latest official requirements and confirming with a licensed plumber in your project location.

My job is to try to find and solve as many problems as possible while the goods are still in China.

Because when sourcing from another country:

Finding the product is only the first step. Making sure everything goes smoothly until shipment is the real work.
