Australia did something no other country had done: it banned engineered stone outright. For kitchen fabricators and benchtop distributors, that removed the single most-specified product in the category and forced a genuine rethink. Natural granite is the obvious replacement, and it is not affected by the prohibition — but importing it into Australia has two requirements that catch newcomers, and neither is about the stone itself.
What was banned, and when
The prohibition covers engineered stone — the manufactured composite of crushed quartz bound in resin that dominated benchtops for two decades. Australian work health and safety ministers agreed to prohibit its use, supply and manufacture, with the domestic prohibition commencing 1 July 2024, and engineered stone becoming a prohibited import from 1 January 2025.
The prohibition covers manufacture, supply, processing and installation. Engineered stone is roughly 90–97% crystalline silica, which is what drove it. The ban does not touch natural stone — granite is around 30% silica and safe once installed — which is why benchtop demand is shifting toward natural granite. Confirm the current scope wording and dates against Safe Work Australia and the relevant Commonwealth import regulations before relying on them.
The reason was occupational health. Engineered stone contains a very high proportion of crystalline silica, and cutting or grinding it dry releases respirable crystalline silica dust. Sustained exposure caused an acute wave of silicosis among Australian benchtop fabricators — young workers, in an industry that had grown quickly. The ban was a response to that, not to the aesthetics or the performance of the product.
Why natural granite is not in scope
Natural granite is a different material and is not covered by the prohibition. It remains lawful to import, fabricate and install in Australia.
The distinction is one of composition. Engineered stone is roughly nine-tenths crushed quartz by weight; natural granite typically contains a substantially lower proportion of crystalline silica, commonly cited at around 30 percent though it varies by stone. That materially lower content is part of why the regulatory response separated the two.
One honest caveat, because it protects your business as much as your workers: a lower silica content is not zero. Cutting, grinding or polishing any silica-bearing stone dry produces respirable dust. Australian fabricators still carry ordinary work health and safety duties — wet cutting, extraction, monitoring and respiratory protection remain necessary practice with natural stone. Anyone selling granite as “the safe one” without that qualification is overselling it.
The commercial consequence has been a straightforward demand shift. Benchtop volume that used to go to engineered slabs is now looking for natural stone with consistent supply, predictable colour and reliable sizes.
The colours that work as benchtops
Australian kitchen specification has its own character — a preference for calm, contemporary surfaces, with figured stone used deliberately rather than throughout. The Indian granites that fit that brief:
- Absolute Black — uniform, dense, no movement. The closest natural equivalent to the plain dark engineered slabs the market is replacing, and the easiest substitution to sell.
- Steel Grey — mid-to-dark grey with restrained movement. The natural answer to the grey composites that dominated Australian kitchens.
- Viscount White — a light ground with fine grey veining, for buyers who wanted a white or marble-look surface without engineered stone.
- Black Galaxy — black with gold flecking, for a more premium finish at a similar footprint.
- Tan Brown — warm and forgiving in daily use, a long-standing seller in the Australian market.
Where a client wants the benchtop to be the feature, exotic granites such as Kashmir Gold and Colombo Juparana carry genuine movement — covered in our guide to exotic Indian granite feature colours. Browse the full range on the granite catalog, by tone under black and grey, or start with our best sellers.
On format: Australian benchtops are specified in millimetres, and 20 mm and 30 mm are the two that matter. 30 mm is standard where an unsupported overhang or a full mitred edge is wanted; 20 mm is used with a mitred build-up to read thicker. Polished is the dominant finish. The wider slab-and-thickness picture is set out in our granite countertop sourcing guide.
Which colours are held specifically for the Australian market, and which edge profiles can be supplied — mitred, bullnose, pencil round and shark nose among them — are best confirmed against current stock; ask for the current benchtop list.
ECTA duty — and the document that unlocks it
The India–Australia Economic Cooperation and Trade Agreement gives qualifying Indian goods preferential duty treatment on entry to Australia. For an importer, this is the difference between a competitive landed cost and an ordinary one.
The India–Australia ECTA has been in force since 29 December 2022, giving qualifying Indian stone 0% or preferential duty against the MFN rate — but only when the Certificate of Origin is claimed. Arrive without it and MFN applies. Verify the current 6802 rate before quoting.
The preference is not automatic. It has to be claimed at entry, supported by a valid Certificate of Origin demonstrating that the goods meet the agreement’s origin rules. Arrive without that document and the standard rate applies — the negotiation is worth nothing without the paperwork. Ask your supplier, before you order, whether they issue the Certificate of Origin as routine. We cover this across markets in import duty on Indian stone in 2026.
Biosecurity: the requirement that catches first-time importers
Australia operates some of the strictest biosecurity controls in the world, and stone consignments are not exempt because stone is inert. The concern is not the granite — it is everything travelling with it.
What is inspected, in practice:
- The stone itself — free of soil, mud and quarry residue. Slabs that left a yard with dirt on the base are a real risk.
- Timber packaging — crates, pallets and dunnage must meet ISPM-15, treated and marked.
- The container — swept and clean internally, free of seeds, plant debris, insects, nests and animal material.
- A-frames and steel — reused shipping frames are a common source of carried-over contamination.
A consignment that fails inspection can be held, directed for cleaning or fumigation, or in serious cases ordered for re-export — at the importer’s cost, with the delay landing on your project. This is a supplier-discipline problem, and it is solved before the container is sealed rather than after it arrives.
Ask any supplier to set out their container inspection, cleaning and pre-seal checking procedure in writing before the first shipment — a verbal assurance is worth very little at the quarantine desk.
Freight, standards and timelines
Indian stone sails to Australia from Mundra or JNPT (Nhava Sheva). Transit to Fremantle is the shortest run; east-coast ports such as Melbourne, Sydney and Brisbane take meaningfully longer, and that difference belongs in your stock planning rather than being discovered later.
Remember that granite loads to weight, not volume — at roughly 2.65 tonnes per cubic metre a container reaches its payload limit before it fills. On standards, AS/NZS requirements apply alongside the National Construction Code; confirm with your certifier what evidence is expected for the specific application.
What to ask a supplier before you order
- Will you issue a Certificate of Origin for the ECTA claim, as standard?
- What is your container cleaning and biosecurity procedure, in writing?
- Is your timber packaging ISPM-15 treated and marked?
- Can you supply 20 mm and 30 mm in the colours I need, consistently, across repeat orders?
- Do you photograph the loaded container before sealing?
Gemarix sources directly from quarries within roughly 400 km of Udaipur, inspects at three stages — block, after cutting, and before packing — and photographs every container before the doors are sealed. Our quality control and export operations pages set out how that works.
Frequently Asked Questions
Is natural granite affected by the ban? No. The prohibition applies to engineered stone. Natural granite remains lawful to import, fabricate and install — though normal silica dust controls still apply when cutting it.
Do I still pay duty on Indian granite? ECTA provides preferential treatment for qualifying goods, but only when claimed at entry with a valid Certificate of Origin.
What biosecurity rules apply? Stone, packaging and container must be free of soil, seeds and organic matter, with ISPM-15 compliant timber. Non-compliance means holds, cleaning orders or re-export at your cost.

Replacing engineered stone, properly
If you are rebuilding a benchtop range around natural granite, the questions worth settling early are colour consistency across repeat orders, thickness, edge profile and whether your supplier treats the Certificate of Origin and biosecurity clearance as their job or yours. Tell us what your market specifies and we will quote against it, or ask for samples in the colours you intend to run.
