Should state governments require companies to fund research into alternative product technologies?
Texas-based spray foam manufacturer Quadrant Performance Materials has sued the California Department of Toxic Substances Control. The lawsuit challenges a state mandate requiring companies to pay a fee of two cents per pound of spray foam sold in California.
Why it matters
The agency established the fee to fund the Green Chemistry and Engineering Innovation Fund, targeting the replacement of methylene diphenyl diisocyanates, which are linked to respiratory sensitization and asthma. The company argues that the regulation restricts its ability to conduct independent research and violates constitutional protections.
The regulation imposes a two-cent levy for every pound of spray foam sold in California for a five-year duration. This funding supports research into safer alternatives for chemicals currently deemed hazardous by the state agency.
The players
Quadrant Performance Materials
A Texas-based manufacturer of spray foam insulation products currently contesting state regulatory requirements.
California Department of Toxic Substances Control
The state regulatory agency responsible for managing chemical safety and implementing the Green Chemistry and Engineering Innovation Fund.
The details
The California Department of Toxic Substances Control has identified methylene diphenyl diisocyanates—a class of chemicals used in foam production that can trigger chronic respiratory conditions like asthma—as a primary target for investigation. The state mandate requires manufacturers to contribute to a dedicated research fund, effectively barring companies from performing independent research to resolve the identified chemical concerns. Quadrant Performance Materials argues this structure infringes upon the First Amendment and the Commerce Clause.
Timeline
California began requiring spray foam manufacturers to pay the state-mandated fees in August 2026.
The required payment schedule spans a five-year duration.
The Tech Race
This case reflects the ongoing tension between state-led Green Chemistry mandates and the manufacturing standards of out-of-state firms. It tests whether administrative research fees align with constitutional protections governing interstate commerce.
The lawsuit creates uncertainty regarding the long-term availability of specific spray foam insulation products sold by the manufacturer in California. If the litigation remains unresolved, the company faces potential exit from the California market.
The takeaway
This lawsuit highlights the regulatory hurdles emerging as states implement stricter chemical oversight for building materials. Industry participants should monitor upcoming court proceedings to see if the fee mandate is upheld or struck down by the judiciary.
