The difference between manufacturer and agrochemical formulator is provided in Decree 4.074 / 02, as in Art. 1, subsection XII and XIV:
XII – manufacturer – natural or legal person authorized to produce components;
XIV – formulator – natural or legal person qualified to produce agrochemicals and related products;
In short, the manufacturer is the industry that produces the technical product, since the formulator is the industry that produces the pesticide. It may be the same industry or formulator to purchase the technical product from another company, provided that it is previously authorized in the Product Registration Certificate issued by MAPA.
