Dow caustic soda is made to exacting specifications in modern production facilities with advanced process and analytical instrumentation. Each of Dow’s caustic soda manufacturing locations are ISO 9001:2008, 14001 and 50001 certified. These certifications mean that Dow not only meets rigid international standards for quality production methods, but that quality assurance systems are validated by regular external audits.
