Pesticide formulation codes explained

EC, SC, WG and similar codes identify how a pesticide product is formulated. They help buyers compare physical form and handling requirements, but they do not prove quality or registration status.

What a formulation code tells you

The code describes the formulation type supplied to the buyer: for example, a liquid concentrate, suspended particles, a powder or water-dispersible granules. The terminology below follows the official CIPAC formulation-code list. FAO registration guidance also treats formulation type and code as core product information.

Common formulation code directory

EC
Emulsifiable concentrate
A homogeneous liquid formulation applied after dilution as an emulsion.
SC
Suspension concentrate
A stable suspension of active ingredient particles in a fluid, intended for dilution before use.
SL
Soluble concentrate
A liquid formulation that forms a true solution after dilution in water.
WP
Wettable powder
A powder formulation designed to form a suspension after dispersion in water.
WG
Water dispersible granule
Granules designed to disintegrate and disperse in water before application.
SP
Water soluble powder
A powder formulation intended to form a true solution in water.
ME
Micro-emulsion
A clear to translucent liquid formulation that forms or is a micro-emulsion.
OD
Oil dispersion
A stable suspension of active ingredient particles in an organic fluid.
CS
Capsule suspension
A stable suspension of capsules containing active ingredient in a continuous fluid phase.
FS
Flowable concentrate for seed treatment
A stable suspension intended for application to seed, as supplied or after dilution.
DS
Powder for dry seed treatment
A powder intended for direct application to seed without water.
ZC
Mixed formulation of CS and SC
A formulation combining capsule-suspension and suspension-concentrate components.

Information to include in an enquiry

  • Active ingredient and required concentration.
  • Formulation code and preferred pack size.
  • Destination country and intended professional market.
  • Required specification, SDS, COA or registration-support documents.
  • Any transport, language or private-label requirements.

Verify before selection

Compare the full product identity and destination-market requirements rather than selecting by a two-letter code alone. Our official-source directory explains where to begin that verification.
