My product has 3 parts on the registration number and I can't find all 3 on the approved website for List N. Why?
The first 2 parts of the EPA Registration Number are the primary numbers and represent the primary registration. Since different companies sell products with the same chemical composition and efficiency, only 1 brand or product name receives the primary number. The third part represents the distributor of the primary registration and is still on List N and is proven effective against SARS-CoV-2 (COVID-19).
