Eastern Technologies, Inc. offers many biocide chemistries encompassing 43 US-EPA registered products to qualified water treatment service companies only. Collectively, these biocides cover a wide range of US-EPA registered water treatment uses. ETI maintains formulating, packaging, and private labeling agreements with our biocide manufacturers. These agreements permit us to provide private labeled products packaged in pails, drums and totes. ETI services include laser printed labels, MSDS, and experienced technical consultation for biocide selection and cost effective application. ETI can provide US-EPA supplemental registrations with private labeling for all biocide chemistries. Also, many products¹ can be marketed and sold with the manufacturers' label thereby avoiding the need to apply for and pay individual USA state registrations.
