The engineered stone ban: compliant benchtops you can still import from China
14 June 2026 · 9 min read
Why the engineered stone ban changes how you spec a benchtop
Australia became the first country in the world to ban engineered stone benchtops. From 1 July 2024, the manufacture, supply, processing and installation of engineered stone benchtops, panels and slabs is prohibited, and import controls have followed. For a builder mid-project the question is simple: what can you still put on a kitchen island, and can you still source it cheaply from China?
You can. Natural stone, porcelain and sintered stone are not engineered stone, they remain legal, and Chinese factories produce all three at a fraction of Australian retail. This guide explains what the ban actually covers, the compliant alternatives worth importing, what they cost landed, and the on-site obligations that do not disappear just because you switched material. The ban is a workplace health and safety measure, so confirm the current scope with Safe Work Australia or your state WHS regulator before you finalise a spec.
What the engineered stone ban actually covers
The prohibition targets engineered stone benchtops, panels and slabs. Engineered stone in this context is a manufactured product made by binding crushed stone with resin or other chemical binders, the quartz-composite material that dominated kitchens for the last fifteen years.
The most misunderstood point: the prohibition applies regardless of the crystalline silica content of the product. The low-silica and silica-free engineered stone that some suppliers marketed as a way to keep selling the same look is still caught if it is an engineered stone benchtop, panel or slab. Silica content is not the test. The product category is.
What is not caught by the benchtop ban:
- Porcelain panels and slabs
- Sintered stone
- Natural stone such as marble, granite and quartzite
- Ceramic tiles, concrete, timber, stainless steel and solid surface acrylics
These are different materials, not engineered stone, and remain legal to supply and install. Treat the boundaries as something to confirm with your WHS regulator, because the definitions and any transitional arrangements carry detail that matters on a specific job.
The compliant alternatives you can still import
For builders sourcing from China, the realistic field narrows to three materials that ship well and cost far less than Australian retail: porcelain, sintered stone, and natural stone.
| Material | Look | Heat and scratch | Notes for compliance |
|---|---|---|---|
| Porcelain slab | Marble, concrete, stone looks | Excellent heat, very hard | Not engineered stone, fully legal |
| Sintered stone | Wide range, large format | Excellent heat, very hard | Not engineered stone, fully legal |
| Natural marble | Classic veining, unique slabs | Marks and etches, softer | Natural stone, legal, more maintenance |
| Natural granite | Speckled, dense | Very durable | Natural stone, legal |
| Natural quartzite | Marble look, very hard | Very durable | Natural stone, legal |
Porcelain and sintered stone are the closest like-for-like replacements for the quartz composite look people are used to. Natural stone is the choice where you want genuine stone and accept the upkeep.
Porcelain and sintered stone: the closest like-for-like
Porcelain and sintered slabs are large-format pressed and fired panels, commonly 12mm to 20mm thick for benchtops, in formats up to around 1600 by 3200mm. They are non-porous, highly heat-resistant, and scratch-resistant, and the better factories produce convincing Calacatta and Statuario looks with the veining carried through the body rather than just printed on the surface.
What to check before ordering:
- Thickness and format. 20mm reads as a substantial benchtop. 12mm is used with a mitred edge built up to look thicker. Confirm which you are getting.
- Through-body veining. On a mitred edge, surface-only patterning shows a plain line at the corner. Full-body or carried veining looks right on the edge.
- Finish. Polished, matt, and textured options behave differently for marking and fingerprints. Get a physical sample.
- Fabrication. Porcelain is brittle and needs a fabricator experienced with large-format slabs and the right tooling. Cut-outs for sinks and cooktops are where inexperienced fabricators crack panels.
If you are weighing porcelain against natural stone on price and look, our stone benchtop cost guide breaks the numbers down further.
Natural stone: marble, granite and quartzite
Natural stone is quarried, so every slab is unique. Chinese factories both fabricate imported Italian and Brazilian slabs and supply domestic stone, and finished benchtops cut to template are often cheaper than buying raw slabs locally because of the labour difference.
Marble gives the classic veined look but marks and etches and wants sealing and care. Granite is dense and very durable. Quartzite delivers a marble look with far greater hardness, and has become popular precisely because it stands in for engineered stone aesthetically without being engineered stone. Specify the grade and finish, and get slab photos or physical samples before production, because you cannot adjust a natural slab once it is cut.

What it costs landed from China
For roughly 8 lineal metres of 650mm benchtop (about 5.2 sqm) in a porcelain Calacatta look, finished and edged in China:
| Item | Range (AUD) |
|---|---|
| Factory price (finished benchtops) | $2,000–$3,800 |
| Crating and export packaging | $300–$500 |
| Sea freight (shared container) | $600–$1,000 |
| Customs duty (typically nil under ChAFTA) | $0–$250 |
| GST (10% of value + duty + freight) | $300–$550 |
| Clearance and delivery | $500–$800 |
| Total landed | roughly $3,700–$6,900 |
Equivalent finished benchtops through an Australian merchant commonly run $7,500 to $14,000. For how the duty and GST lines are worked out, see our duty and GST guide.
On-site silica controls still apply
A critical point that the ban does not change. Cutting, grinding and dry-processing porcelain, sintered stone and natural stone on site still generates respirable crystalline silica. The engineered stone ban removed one high-risk product, but the workplace dust rules for silica apply to these materials too.
That means water suppression or on-tool dust extraction, the right respiratory protection, and avoiding uncontrolled dry cutting. Sourcing benchtops cut and finished to template at the factory is one of the cleanest ways to minimise on-site cutting in the first place. Confirm the current silica dust control requirements with your state WHS regulator.
Common mistakes when replacing engineered stone
Assuming silica-free engineered stone is a loophole. It is not. The benchtop ban applies regardless of silica content, so a silica-free engineered stone benchtop is still banned.
Confusing porcelain with engineered stone. They are different materials. Porcelain and sintered stone are not engineered stone and are not caught by the benchtop ban.
Booking a standard fabricator for porcelain. Large-format porcelain is brittle and needs a fabricator with the right tooling and experience, or you pay for cracked panels.
Forgetting on-site silica controls. Natural stone and porcelain still produce silica dust when cut. The dust rules still apply.
Not confirming scope with the regulator. Definitions and transitional detail matter on a specific job. Confirm with Safe Work Australia or your state WHS regulator before you finalise the spec.
Frequently asked questions
Is engineered stone banned in Australia? Yes. Since 1 July 2024 the manufacture, supply, processing and installation of engineered stone benchtops, panels and slabs is prohibited, with import controls following. The ban applies regardless of the product's crystalline silica content.
Can I still import quartz benchtops from China? Not as engineered stone benchtops, panels or slabs. Quartz composite of that kind is caught by the ban. Porcelain, sintered stone and natural stone are legal alternatives you can import.
Is porcelain affected by the ban? No. Porcelain is not engineered stone, so porcelain benchtops are not covered by the engineered stone prohibition. On-site silica dust controls still apply when it is cut.
Is sintered stone the same as engineered stone? No. Sintered stone is a different material, made by fusing mineral particles under heat and pressure without the resin binder that defines engineered stone, and it is not caught by the benchtop ban.
Threadline only sources benchtop materials that are compliant in Australia, supplies finished benchtops cut to template to keep on-site cutting down, and handles freight, duty and delivery as one landed price. If you want a compliant benchtop package costed for your project, start a request.
