Founded on a unique multi-disciplinary collaboration between experienced environmental attorneys and preeminent in-house scientists, Keller and Heckman’s Chemical Control Practice is at the forefront of laws and regulations applicable to commercialization of emerging new chemical technologies, as well as existing chemical substances. Our highly-skilled attorneys, many of whom have technical backgrounds and extensive private industry experience, work closely with our distinguished in-house scientific staff – most of whom are Ph.D. chemists – to provide informed counsel and invaluable understanding on a broad array of chemical-related issues at the interface of law and science. Our diverse multi-jurisdictional practice has forged longstanding relationships with international chemical regulatory agencies, regularly engages in discussions with worldwide government authorities, and is intricately involved in developing advocacy and defensive positions with regard to chemicals around the globe.

We advise clients on compliance with the U.S. Toxic Substances Control Act (TSCA); the EU Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) legislations; and similar schemes in Australia, Canada, China, Japan, the Philippines, South Korea, Taiwan, and New Zealand, among others. We counsel clients on the initiatives concerning international chemical testing, persistent organic pollutants (POP), volatile organic compounds (VOC), the Chemical Weapons Convention, and the Global Harmonized System (GHS) for hazard communication. We assist clients in navigating the Harmonized Tariff Schedule (HTS) classifications for substances and in managing other international trade issues. With years of global chemical regulation expertise, we provide clients with thorough and efficient solutions to legally and scientifically complex issues.

Keller and Heckman prides itself on being a “full service” chemical control law firm. We assist clients with all aspects of efficiently bringing innovative new chemicals to market and defending existing products. With a strong business sense, we ensure that our clients fully understand and appreciate all legal rights and obligations, and provide strategic advice designed to minimize or eliminate the commercial disruption and monetary fines that can result from non-compliance.

Keller and Heckman attorneys and scientists are actively involved with and are frequently asked to lecture at chemical control conferences within the U.S. and around the world. We host an annual Chemical Control Law Seminar that provides chemical manufacturers, importers, processors, and users with essential, in-depth information regarding recordkeeping and reporting requirements, compliance auditing, and prioritization, risk evaluation, and risk management of existing chemicals. We also host frequent webinars – TSCA 30/30 and REACH 30/30 –providing relevant and timely updates to the industries we serve.
