A bill advancing through Congress would retroactively dismiss roughly 500 pending lawsuits against stone countertop manufacturers and permanently bar new ones — even as silicosis, a lung disease tied to cutting engineered quartz, continues to sicken fabrication workers nationwide. Full coverage of what's in the bill, who's pushing it, and what happens if it passes is available now at Silica Free News.
The House Judiciary Committee voted 16-7 on June 3, 2026 to advance the Protection of Lawful Commerce in Stone Slab Products Act (H.R. 5437). The bill would use a federal preemption provision to block civil lawsuits against manufacturers, distributors, and sellers of stone slab products — including engineered quartz, natural stone, and porcelain — for harm caused by how a third party later fabricates the material. Pending cases already in court would be dismissed within 30 days of enactment.
That distinction matters on renovation and ADU projects specifically. The material itself doesn't get cut in a factory before it reaches a home — it's cut, shaped, and polished by a local fabrication shop, often the same shop a contractor calls in for a kitchen or bath remodel. The bill's core argument is that liability for worker illness caused during that cutting process should sit with the shop doing the cutting, not the company that made the slab. Critics counter that the shops most likely to violate dust-control rules are also the least likely to carry the insurance or capital to absorb that liability, which would leave injured workers with little recourse either way.
For homeowners and contractors, the bill doesn't change what's available on a spec sheet today — engineered quartz, granite, and low-silica or silica-free alternatives are all still on the market regardless of how the bill turns out. What it does change is who bears legal responsibility if a fabrication shop's workers are harmed making the material used in a project. That's a relevant data point for any contractor vetting a fabricator or distributor as part of a renovation bid, particularly on projects where the client has asked about material safety.
The legislation also arrives alongside a wave of state-level activity moving in the opposite direction. California has been tightening its own rules — a 2023 emergency standard, a 2026 dry-cutting ban for high-silica material, and a new attestation requirement that took effect July 1, 2026 requiring fabrication employers to confirm worker safety training. Australia went further in 2024 and banned high-silica engineered stone outright, without touching manufacturers' civil liability — and the ban didn't eliminate the countertop market, since major manufacturers pivoted to low-silica and silica-free formulations instead.
H.R. 5437 has passed committee but still needs a full House vote, and the Senate hasn't taken it up. The full legislative breakdown — including the House testimony, the two multi-million-dollar jury verdicts driving the industry's push for the bill, and what regulators in other countries have done instead — is covered in detail at Silica Free News, an independent trade publication tracking the silica-free and low-silica countertop industry across the U.S. renovation and construction market.
