Low-Silica and Silica-Free Quartz: What the Industry Shift Means for Your 2027 Kitchen
Quick answer: The quartz industry is reformulating its products to remove crystalline silica because of a serious lung-disease risk to the workers who cut and polish slabs — not because installed countertops are dangerous. An existing quartz top is safe in normal household use. By 2027, expect more low-silica and silica-free versions of familiar colours in Metro Vancouver showrooms — manufacturers say they look and perform the same as before.

Over the past year, clients visiting our Richmond shop have started asking two questions we never used to hear: “Is quartz being banned?” and “Is my countertop giving off silica?” The short answers are no and no — but behind the questions sits the biggest change in engineered stone since quartz overtook granite. Here is what changed, who was at risk, how the brands we carry responded, and what to check before ordering quartz for a 2027 project.
Why is the quartz industry removing crystalline silica?
Traditional engineered quartz is typically more than 90% crystalline silica — quartz itself is a crystalline form of silica — bound with polymer resin. Cut, ground, or polished dry, a slab releases very fine respirable silica dust. Breathed in over time, it causes silicosis: an incurable, progressive scarring of the lungs. Agencies such as NIOSH and OSHA frame this risk entirely around the people who fabricate, finish, and install the stone.
The scale of the worker problem became impossible to ignore. A 2026 study in NEJM Evidence identified 592 silicosis cases among California engineered-stone countertop workers between January 2019 and June 2026, including 65 lung transplants and 31 deaths. Regulators responded — OSHA began focused inspections of fabrication shops in 2023, and Australia went furthest — and manufacturers re-engineered their recipes. That is why “silica-free quartz” exists: shorthand for engineered surfaces that keep the look and workability of quartz while swapping crystalline silica for other minerals and, in several lines, recycled glass.
Who is actually at risk — fabrication workers or homeowners?
This is the most important distinction in the story, and the one most often mangled online: silicosis is an occupational disease of fabrication workers, caused by respirable dust from cutting, grinding, and polishing. It is not a hazard of living with an installed countertop. A finished surface releases dust only when it is abraded — food prep, cleaning, and daily kitchen use do not do that. Canada’s national occupational health body, CCOHS, identifies workers who process the material as the at-risk group; consumers with installed tops are not listed as an exposure group.
| Situation | Silica risk | Why |
|---|---|---|
| Living with an installed quartz countertop | No silica exposure in normal use | Dust occurs only when the material is abraded; daily use does not abrade it |
| Cutting, grinding, or polishing slabs in a fabrication shop | Serious — the core hazard | Dry processing releases respirable silica dust — the source of the disease cases |
| On-site trimming and finishing during installation | Managed with proper controls | Wet methods and exposure control plans are required for this work in BC |
| DIY cutting or demolition of an old engineered-stone top | Real risk — do not dry-cut | Uncontrolled cutting creates the same dust; hire professionals who use wet methods |
The clearest signal: Australia, which banned engineered stone outright, explicitly left every installed benchtop in place. If installed quartz were a household hazard, removal would have been mandated. Instead the law regulates only the dusty work of repairing, modifying, or removing a top — exactly where the risk lives.
Did Australia really ban engineered stone?
Yes. From 1 July 2024, every Australian state and territory made it an offence to manufacture, supply, process, or install engineered-stone benchtops, panels, and slabs — defined as artificial stone containing at least 1% crystalline silica by weight. It was a world-first workplace-safety law, and Safe Work Australia is clear about its boundaries: already-installed benchtops stay, and their repair, minor modification, or removal is allowed under controlled-processing rules. Imports of engineered-stone benchtops, slabs, and panels were banned from 1 January 2025, and stronger dust rules now apply to work with any material over the 1% threshold.
Worth knowing: porcelain and sintered surfaces sit outside Australia’s engineered-stone definition — one reason that category has momentum into 2027. Our porcelain vs quartz comparison covers the practical differences.
Is quartz being banned in Canada or the United States?
No — and jurisdiction matters, so here it is precisely, as of August 2026. In Canada and BC there is no ban and no product restriction. WorkSafeBC treats silica as a workplace exposure: shops that process stone must run exposure control plans and wet methods, rules in force since 2017. We have found no BC or federal move toward a product ban.
In the United States there is no federal ban either — OSHA enforces its silica standard and has inspected fabrication shops since 2023. California is the jurisdiction to watch: it adopted a permanent, stricter silica standard for engineered-stone work in late 2024, and in May 2026 its Standards Board voted to direct drafting of an emergency rule that would effectively prohibit fabrication and installation of engineered stone over 1% crystalline silica. That proposal is advancing but is not law as of August 2026 — and either way it is a California fabrication rule, not a Canadian one, and touches no installed countertop anywhere.
Which brands sell low-silica or silica-free quartz?
We fabricate and install Caesarstone, Cambria, Silestone, HanStone, Vicostone, and Dekton, so we have no favourite in this race. Here is who has announced what, as of August 2026.
| Brand | What has been announced | Stated crystalline silica content | Status as of August 2026 |
|---|---|---|---|
| Caesarstone | Mineral crystalline-silica-free (CSF) collection (33 designs through 2024) plus ICON, a CSF surface the company says is made with about 85% recycled materials, launched at KBIS 2025 | Marketed as crystalline-silica-free | Stated goal: fully crystalline-silica-free portfolio by end of 2026; Mineral and ICON lines listed by Caesarstone Canada as of August 2026 |
| Silestone (Cosentino) | Silestone XM, announced April 2024 — all collections moved to the new mineral formulation | Maximum 10% | Shipping; manufacturer claims unchanged performance and colour depth |
| Compac | Obsidiana low-silica line; “Volcano Zero” variants made from recycled glass | Reported under 7%; some variants marketed silica-free | Canadian availability unconfirmed |
| Aurea Stone | ZERO line, reported at 0% crystalline silica with high recycled mineral content | Reported 0% | Canadian distribution unverified |
| Cambria, HanStone, Vicostone | No low-silica or silica-free line announcements we could verify | No published reformulation figures | No announced change as of August 2026 |
| Dekton | Not applicable — Dekton is a sintered ultracompact surface, not resin-bound quartz; a different category | — | Unchanged category |
One Canadian footnote: HanStone is manufactured in London, Ontario by Hyundai L&C Canada — the only quartz-surface plant in Ontario — which shortens its supply chain into BC even though the brand has announced no reformulated line as of August 2026.
Will silica-free quartz look or perform differently?
The manufacturers say no. Caesarstone states there is no visible difference between the CSF versions and the original engineered-stone versions of the same colours, and Cosentino claims Silestone XM matches the physical and mechanical performance of what it replaced. Those are manufacturer claims, passed along as exactly that — independent long-term field data does not exist yet. Our advice: view a full slab of the actual new-formula product rather than an old sample chip, and ask how the warranty reads. Day-to-day care is expected to be the familiar routine — see our quartz countertop care guide — but confirm care instructions for the specific line you buy.
What does the shift mean if you are planning a 2027 kitchen?
Practically, four things. First, availability: based on what manufacturers have announced, more of the quartz wall at any Metro Vancouver dealer will be low-silica or silica-free versions of familiar colour names by 2027. Second, ask which formulation you are getting — colour names carry over, so the same name may exist in both recipes during the transition. Third, pricing on the reformulated lines is still settling — we have seen no reliable data either way — so get current quotes rather than assuming a premium or a discount; our 2027 cost outlook covers the wider picture and our Vancouver cost comparison has today’s ranges. Fourth, there is no health reason for a homeowner to avoid quartz — but if you want alternatives anyway, our materials comparison lays out granite, quartzite, porcelain and more.

What do we do about silica in our own shop?
The worker-safety side of this story is personal for us — it is our trade. In our Richmond facility, slab cutting runs wet, as WorkSafeBC’s exposure-control requirements for silica work demand, and dust control is a baseline of doing business for us, not a selling point. The same logic applies to your old countertop: modifying or removing an engineered-stone top creates dust, so it belongs with professionals using wet methods — not a rented angle grinder in a closed kitchen.
Frequently asked questions
Is my existing quartz countertop safe?
Yes — in normal household use an installed quartz countertop poses no silica risk. Silica exposure happens when the material is cut, ground, or polished, which is why the risk sits with fabrication workers, not homeowners. Australia’s engineered-stone ban left every installed benchtop in place for exactly this reason. Care is needed only when a top is cut or removed: have that done professionally with wet methods.
Is quartz being banned in Canada?
No. As of August 2026 there is no ban or product restriction in Canada or BC. WorkSafeBC regulates silica as a workplace exposure for shops like ours. Australia banned engineered stone in July 2024 as a worker-safety law, and California is advancing a proposal that would restrict fabrication there, but no Canadian jurisdiction has moved to ban the product.
Should I avoid quartz for my 2027 renovation?
There is no health reason to. The industry shift is about protecting workers during fabrication, and reputable shops already control that risk. If anything, 2027 buyers benefit: more low-silica and silica-free lines to choose from, in familiar colours. If you simply prefer an alternative, porcelain, quartzite, and granite all remain strong options.
Will silica-free quartz look different from regular quartz?
Manufacturers say no — Caesarstone states its CSF versions show no visible difference from the originals, and Cosentino claims Silestone XM performs and looks the same. There is no independent long-term data yet, so view a full slab of the actual new-formula product in person before committing.
Can I cut or modify my old quartz countertop myself?
No — do not dry-cut engineered stone. Cutting, grinding, or drilling releases respirable silica dust, the same hazard behind the industry’s worker-safety crisis. Hire professionals using wet cutting and dust controls; BC requires silica exposure control plans for this work.
