The Geography of Forever: Global PFAS Production and Trade
When 3M announced the phase-out of PFOS and PFOA production in 2000, and when DuPont committed to PFOA phase-out under the EPA’s 2010/2015 PFOA Stewardship Program, Western observers might have concluded that PFAS production was winding down globally. In reality, production simply migrated—primarily to China, where manufacturers with less regulatory constraint rapidly expanded PFAS manufacturing capacity to serve both domestic demand and export markets. Understanding today’s global PFAS production landscape is essential for interpreting both contamination patterns and the feasibility of global regulatory controls.
China’s Dominance in Global PFAS Production
China has become the world’s largest PFAS producer, manufacturing an estimated 30,000 to 50,000 tonnes of fluorochemicals annually—a volume that encompasses both legacy PFAS compounds (PFOS and PFOA are still produced in China for domestic use and export, subject to limits under China’s implementation of the Stockholm Convention) and next-generation alternatives including short-chain PFAS and fluoropolymers. Key production clusters are located in Zhejiang Province (particularly around Quzhou), Inner Mongolia, Jiangxi Province, and Shandong Province, where fluorite mining provides the raw material base for fluorochemical manufacturing.
Chinese PFAS manufacturers—including Juhua Group, Dongyue Chemical, and Sinochem—have expanded production of GenX compounds (HFPO-DA), short-chain PFAS like perfluorobutane sulfonic acid (PFBS), and fluoropolymers including PTFE, PVDF, and ETFE as Western chemical companies faced regulatory restrictions. This “regrettable substitution” cycle—where restrictions on one PFAS drive adoption of another that is later discovered to be similarly problematic—has been a consistent pattern in PFAS regulatory history.
European and U.S. Production Transitions
In Western markets, PFAS production has shifted from general-purpose mobile PFAS toward specialized high-performance fluoropolymers with established industrial applications. Companies including Chemours (U.S.), Solvay (Belgium), Daikin (Japan, with production in multiple countries), and AGC (Japan/U.S.) continue producing fluoropolymers—PTFE, Teflon, Viton, and specialty grades—that are critical to semiconductor manufacturing, electric vehicle battery technology, and aerospace applications. These companies are increasingly the subject of regulatory scrutiny regarding PFAS manufacturing byproducts and wastewater discharges, even as they argue for essential use derogations from broad PFAS restriction proposals.
The EU’s PFAS restriction proposal explicitly contemplates a transition period for fluoropolymer production that acknowledges the lack of ready alternatives in several critical industrial applications. Fluoropolymer manufacturers have organized sophisticated regulatory engagement strategies, commissioning economic impact analyses, technical performance comparisons with non-fluorinated alternatives, and supply chain dependency assessments to support essential use arguments. The outcome of this regulatory negotiation will determine whether Europe maintains domestic fluoropolymer manufacturing capacity or becomes entirely dependent on Asian imports for critical materials.
International Trade and Regulatory Asymmetry
The global production geography of PFAS creates regulatory arbitrage opportunities: manufacturers in jurisdictions with less stringent PFAS controls can produce and export products containing PFAS that are restricted in destination markets. Import screening for PFAS content in consumer goods, food contact materials, and industrial products is technically challenging and resource-intensive—most customs agencies lack the analytical capacity to systematically test imports for PFAS compliance. This creates competitive asymmetry between domestic producers who must comply with PFAS restrictions and importers who may face less rigorous enforcement scrutiny, a tension that trade authorities in the EU, U.S., and Japan are beginning to address through import control frameworks.
