GoKawiilCalifornia Moves to Ban High-Silica Quartz Countertops
California is set to pass an emergency regulation this month banning quartz countertops containing more than 1% crystalline silica, according to a New York Times report. The rule targets a material linked to silicosis, an incurable and potentially fatal lung disease caused by inhaling silica dust released during cutting or drilling.
GoKawiil's interpretation of the reporting above, not reported fact.
The move would make California the first US state to restrict quartz countertops, a product used nationwide and valued at an estimated $14.8 billion globally in 2026, which could pressure manufacturers and fabricators to reformulate products or improve safety practices. Workers who cut and install stone countertops face the highest exposure risk, and the regulation could prompt other states to consider similar measures, though it remains unclear if any will follow.
- California plans an emergency ban on quartz countertops with over 1% crystalline silica.
- Silica dust exposure can cause silicosis, lung cancer, COPD and kidney disease, often appearing 15-20 years later.
- Australia is currently the only country with a similar quartz ban, enacted in 2024.
