Formulations & concentrations
Technical materials, single active formulations and mixtures are listed separately, each with its declared content and the tolerance set by the FAO/WHO specification manual. Specifications added to the enquiry list can be sent together with other products in one purchase or registration enquiry.
Technical materials
Technical material for formulators. Each specification states the assay, relevant impurities and test methods.
Single active formulations
Finished formulations of a single active ingredient, packed and labelled for the destination market.
Approved uses differ by country; the label registered in the destination market applies.
Quality specification
Each specification is supplied to the quality clauses that the FAO/WHO specification manual sets for its formulation type, tested by CIPAC methods. The batch certificate of analysis reports the measured values.
