Technical Grade vs Formulation Grade Pesticide: What Bulk Buyers Must Know Before Comparing Quotes

Technical Grade vs Formulation Grade Pesticide: What Bulk Buyers Must Know Before Comparing Quotes11 min read

A technical grade product (TC, or technical material) is the pure-ish active ingredient straight from the factory, usually in the range of 90 percent or more active, with some manufacturing impurities. It is a raw material for formulators, not a pack for farmers. A formulated product (EC, SC, WP, WG, SL, GR and others) is the technical mixed with solvents, carriers and other additives to a stated percent, so it can be diluted and sprayed. Because the active is diluted, never compare two quotes by price per litre or kg. Compare the price per gram of active ingredient: divide the price by the grams of active in the pack. In India the label percent, the registration number and the batch details must match the registration, and technical and formulation each have their own CIB&RC registration route.

What is technical grade in pesticides?

Technical grade means the active ingredient as it comes out of the manufacturing plant, before any formulation. It is called TC (technical material) in specifications. It contains the active at a high percent plus small amounts of by-products from the process, called impurities. It is sold in bulk to formulators and exporters, not in small packs to farmers.

One competitor page says technical actives are typically 90 percent or more and many are specified at 95 to 99 percent. That matches the range most buyers see on quotations, but the exact minimum depends on the molecule and the manufacturer. Always read the number on the specification or certificate of analysis, not a general range.

The FAO/WHO manual gives a useful rule about technicals. TC has no upper limit on content, because the purer the material the better. More active means fewer impurities. So a quote of "95 percent min" means not less than 95 percent, not exactly 95.

What is a formulated pesticide?

A formulated pesticide is a ready-to-use or ready-to-dilute product made by mixing the technical with solvents, carriers, emulsifiers, wetters, stabilisers or fillers. The aim is to make it safe to handle, easy to measure, able to mix with water and able to stick to or enter the plant. The label shows the active percent, such as 25 percent in a water dispersible granule.

You can see real formulations in our single-active posts. For example, thiamethoxam 25 percent WG is a granule that disperses in water, and fipronil 5 percent SC is a liquid suspension. Thiophanate methyl 70 percent WP is a wettable powder. Same family of products, three different physical forms.

What do EC, SC, WP, WG, SL and GR mean?

These are short codes for the physical form of a formulation. The code tells you how the active is carried and how it mixes with water, which is why the same active at the same percent can have a different price in a different form.

CodeFull namePlain meaning
ECEmulsifiable concentrateActive dissolved in solvent. Turns milky when mixed with water
SCSuspension concentrateFine solid active suspended in a thick liquid. Poured and mixed in water
WPWettable powderFine powder that forms a suspension in water
WG or WDGWater dispersible granulesSmall granules that break up in water. Less dust than a powder
SLSoluble liquidDissolves fully in water and gives a clear solution
GRGranulesReady granules spread on soil or water, no mixing

The FAO/WHO manual treats EC, SC and SL as homogeneous formulations and WG and GR as heterogeneous ones, which matters for the tolerance on the label (see the section on label percent).

How does the label percent work: w/w, w/v and g/l?

The label percent shows how much active is in the product. It can be by weight (w/w, grams in 100 grams) or by weight per volume (w/v, grams in 100 ml). Many liquids are shown as g/l. A 25 percent w/w and a 25 percent w/v product are not the same, so check the unit and the density before comparing.

The FAO/WHO specifications manual says solids, liquid technicals, volatile liquids and very viscous liquids are declared in g/kg. Other liquids may be declared in g/kg or in g/l at 20 degrees C. Indian labels often show a percent, so you may need to convert. As a simple rule:

  • w/w percent to grams per kg: multiply by 10. A 25 percent w/w product has 250 g of active in 1 kg.
  • w/v percent to grams per litre: multiply by 10. A 25 percent w/v product has 250 g of active in 1 litre.
  • w/w liquid to grams per litre: you also need the density. If the density is 0.95 kg per litre, then 25 percent w/w gives 250 x 0.95 = 237.5 g per litre (example only, check the real density on the product data sheet).

The same manual allows some difference between what is printed and what a lab finds in a formulation. The table below shows the FAO/WHO tolerance on declared content for formulations. It is a specification rule, not an Indian legal limit, so use it as a guide for what is normal.

Declared content (g/kg or g/l at 20 C)Allowed difference from the declared content (FAO/WHO)
Up to 25Plus or minus 15 percent for EC, SC, SL type; plus or minus 25 percent for GR, WG type
Above 25 up to 100Plus or minus 10 percent
Above 100 up to 250Plus or minus 6 percent
Above 250 up to 500Plus or minus 5 percent
Above 500Plus or minus 25 g/kg or g/l

Why do prices of technical and formulated products differ?

Technical is priced per kg of mostly active ingredient. A formulation is priced per litre or kg of a diluted product, and its price also carries the cost of solvents, additives, milling or granulation, packing, labelling, registration, quality testing, freight and the dealer margin. So a formulation is not the technical price divided by the dilution.

  • Active content: the main driver. A product with more active per litre costs more per litre.
  • Formulation type: SC and WG need special mills and wetting agents. A simple EC may be cheaper to make.
  • Source and purity of technical: a higher purity or a better impurity profile costs more.
  • Packing and label: small retail packs cost more per gram than bulk.
  • Registration and testing: every registered product needs data, batch testing and a licence.
  • Exchange rate and freight: for imported technicals, both move the landed price.

We have not quoted any market price here, because technical and formulation prices change with the season, the source and the exchange rate. Always ask for a current written quotation.

How to compare two quotes: cost per gram of active ingredient

To compare two quotes, work out how many grams of active ingredient you get in the pack and divide the price by that number. The lower cost per gram of active is the better value, if the quality and the label are equal. This avoids the common mistake of comparing price per litre or per kg.

Steps: (1) note the label percent and its unit; (2) convert to grams of active per litre or per kg; (3) multiply by the pack size; (4) divide the pack price by the total grams of active.

Example Only: The numbers below are made-up round numbers to show the method. They are not market prices, and no real brand or product is meant. Supplier A offers a 25 percent w/v EC at Rs 800 per litre. Supplier B offers a 20 percent w/v EC of the same active at Rs 700 per litre. A has 250 g of active per litre, so Rs 800 / 250 g = Rs 3.20 per gram of active. B has 200 g of active per litre, so Rs 700 / 200 g = Rs 3.50 per gram of active. B looks cheaper per litre but costs more per gram of active.

Item (example only)Supplier ASupplier B
Label percent (w/v)2520
Active per litre250 g200 g
Price per litre (made up)Rs 800Rs 700
Cost per gram of activeRs 3.20Rs 3.50
Cheaper per gram of activeA

Two more checks make the comparison fair. First, the dose on the label: if one product needs a higher dose, the real cost per acre changes. Second, the formulation type and the quality: a poorly made SC can settle in the drum or a WP can clog nozzles, so a cheaper gram of active is not always better. For a bulk order, use the checks in our FPO bulk buying guide for MOQ, GST invoice and sampling.

You can also compare a technical quote with a finished product, but only for a rough idea. Technical is cheaper per gram of active, but it needs formulating, testing, registration and packing. Those costs are not in the technical price.

Who buys technical grade and who buys formulations?

BuyerWhat they usually buyWhy
Formulators and contract manufacturersTechnical (TC) and additivesThey make EC, SC, WP or WG themselves under their own licence and registration
Importers and exportersTechnical or formulation, depending on the registrationSee the import and export guides on this blog
Distributors and wholesalersFormulated products in bulk packsThey sell to retail dealers
Retail dealers and agri-input shopsFormulated retail packsSold to farmers with a dealer licence
FPOs and cooperativesFormulated productsBought for member farmers, often in bulk
FarmersFormulated products onlyTechnical is not made for field use

If you are a dealer or FPO, you will almost always buy formulations. If you want to build your own brand without owning a plant, read how private label manufacturing works, where a licensed manufacturer makes to your specification. For fertilisers, the same idea applies in a simpler form: the grade printed on a bag is the nutrient percent, and you compare price per kg of nutrient, not per bag.

What are the Indian regulatory rules for technical and formulation?

In India, pesticides are controlled by the Insecticides Act 1968 and its rules. The Central Insecticides Board and Registration Committee (CIB&RC) registers each pesticide. The CIB&RC guideline sets separate data requirements for technical import (TI), technical indigenous manufacture (TIM), formulation import (FI) and formulation indigenous manufacture (FIM), under Section 9(3), with 9(4) covering later registration of technical manufacture.

Points in the guideline that matter to a buyer:

  • A firm that holds a registration for indigenous manufacture of a pesticide technical or formulation cannot also register the same pesticide under an import category.
  • If a technical is registered for indigenous manufacture to any firm, an application for formulation import of that same molecule will not be considered.
  • For a new-source technical import, only the same or a higher minimum purity than the already registered purity is considered.
  • A label and leaflet is required for all the registration categories (TI, TIM, FI and FIM).
  • Data on impurities is required for technical import and technical manufacture; the guideline marks it as not required for formulation import.

There is also an open policy question on importing a formulation without registering the technical. The 281st Registration Committee minutes show that a decision on this was kept in abeyance for review under the Act. We did not find the final outcome, so check the latest CIB&RC position or ask your regulatory consultant before you plan an import.

This post is not legal advice. For the full import steps, HS codes and the registration papers, read our guide to importing pesticides from India. If you plan to ship out, see the exporters guide.

What must the label and pack show?

Every pack, technical or formulated, must carry a label approved by CIB&RC, because a label and leaflet is part of the registration file. For retail packs, the Insecticides Rules list the particulars to be printed. We could not open the full text of Rule 19, so the list below is from a consultancy page and should be checked against the Rules.

  • Name of the manufacturer and the registrant (if different).
  • Name of the insecticide, brand name allowed.
  • CIB&RC registration number.
  • Active ingredient and other ingredients with percentages.
  • Net content in metric units.
  • Batch number and expiry date.
  • Antidote statement, and the signal word and colour band that show toxicity.

A 2023 amendment to the Insecticides Rules is reported to require a QR code on the retail pack that carries a unique identifier, batch number, date of manufacture, date of expiry and a web link, per a summary of the amendment. Confirm the final text and the date it starts for your product type. For a technical drum, ask the supplier for the batch number, date of manufacture, certificate of analysis and the registration number on the document or label.

What quality markers matter in a technical grade?

The most important marker is the minimum active content on a certificate of analysis for your batch, next to the impurity profile. Impurities are by-products of manufacture. FAO/WHO calls an impurity relevant when it is toxic, harms the crop, spoils stability or has another adverse effect, and these are limited in the specification.

  • Minimum active content: shown in g/kg. The average measured content should not be lower than the declared minimum.
  • Relevant impurities: each has a maximum limit in the FAO/WHO specification. Water and insoluble material can also be relevant, because they can ruin a formulation or block spray nozzles.
  • Same source: FAO/WHO specifications apply to the manufacturer whose technical was evaluated. Another source must show it is equivalent.
  • Physical form and appearance: colour, odour and solid or liquid state should match the specification.
  • Batch records: batch number, date of manufacture and retest date on every drum.

For a formulation, the quality markers move to the declared content within tolerance, how stable it is in storage, how well it mixes (suspensibility or emulsion stability) and whether the pack and label match the registration. The manufacturer checklist explains how to audit these before you sign.

Common mistakes bulk buyers make

  • Comparing price per litre or per kg. Always compare per gram of active.
  • Mixing up w/w and w/v. A 25 percent w/w liquid has less active per litre than a 25 percent w/v liquid if its density is under 1.
  • Buying a "technical" for direct sale. It is not a farm product. If a supplier offers it for field use, ask for the registration and the formulated label.
  • Not asking for a certificate of analysis for each batch. Last month's COA says nothing about this lot.
  • Ignoring tolerance. A small gap between your lab and the label can be within the allowed range. A large gap is not.
  • Accepting a quote with no registration number. An unregistered product cannot be sold legally, whatever its price.
  • Forgetting the licence. Selling pesticide needs a dealer licence. See our dealer licence guide.
  • Ignoring the formulation type. Same active and percent, different form, different handling and storage.

Quick checklist before you accept a quote

  1. Ask: technical or formulation? Which code (EC, SC, WP, WG, SL, GR)?
  2. Write down the label percent and its unit (w/w, w/v, g/l).
  3. Calculate grams of active per pack and the cost per gram of active.
  4. Ask for the CIB&RC registration number and a copy of the approved label.
  5. Ask for a batch-wise certificate of analysis and the batch number and expiry.
  6. Check packing, shelf life and storage conditions.
  7. Test a sample from your first lot at an approved lab before a bulk order.
  8. Agree in writing on payment terms, GST invoice and return of off-spec lots.

Conclusion

Technical grade is a factory raw material, and a formulation is the product that reaches the farm. Compare quotes by cost per gram of active ingredient, check the label unit and tolerance, and ask for the registration number and batch certificate every time.

Questions Farmers Ask

What is the difference between technical grade and formulation grade pesticide?
Technical grade is the pure active ingredient from the factory, usually 90 percent or more active with some impurities. Formulation grade is the technical mixed with solvents and additives to a stated percent, such as 25 percent. Technical goes to formulators. Formulations go to dealers and farmers.
What is technical grade in pesticide?
It is the active ingredient made in the plant before formulation, called TC. It has a high active content and small process impurities. It is sold in bulk to formulators and exporters, and it is not meant for direct use on crops.
Can farmers use technical grade pesticide directly?
No. Technical is a concentrated raw material that is hard to measure, may not mix with water and is more hazardous to handle. Farmers should use a registered formulated product at the dose on its label.
What are the different types of pesticide formulations?
Common types are EC (emulsifiable concentrate), SC (suspension concentrate), WP (wettable powder), WG (water dispersible granules), SL (soluble liquid), GR (granules) and DP (dust). They differ in physical form and how they mix with water.
What is the difference between EC and SC formulation?
EC has the active dissolved in a solvent and turns milky in water. SC has a fine solid active suspended in a liquid and is mixed in water after shaking. SC uses less solvent. Which is better depends on the active and the crop.
Can we mix EC and SC formulations?
Not without a check. Some mixes work and some separate or clog nozzles. Read the labels, follow the registered mixing advice and do a small jar test before spraying a field. Do not mix products only by guess.
How do I compare the price of two pesticide quotes?
Convert each label percent to grams of active in the pack, then divide the pack price by that number. The lower price per gram of active is better value if quality and registration are equal. Do not compare price per litre or kg alone.
What is the difference between w/w and w/v on a pesticide label?
w/w is grams of active per 100 grams of product. w/v is grams of active per 100 ml. For liquids, 25 percent w/v gives 250 g per litre. A 25 percent w/w liquid gives 250 g per kg, which is less per litre if density is under 1.
Is the label percent of active ingredient exact?
Not exactly. FAO/WHO specifications allow a tolerance. For a formulation that declares 25 g/kg or less, it is plus or minus 15 percent for EC or SC type and plus or minus 25 percent for WG or GR type. A larger gap needs investigation.
Who registers technical and formulated pesticides in India?
The Central Insecticides Board and Registration Committee (CIB&RC) under the Insecticides Act 1968. Its guideline has separate routes for technical import, technical manufacture, formulation import and formulation manufacture under Section 9(3), and 9(4) for later technical manufacture.
What documents should I ask for when buying pesticide in bulk?
Ask for the CIB&RC registration number, an approved label copy, a batch-wise certificate of analysis, the batch number with manufacture and expiry dates, a GST invoice and, for technical, the source and impurity data.
Why is technical grade cheaper than a formulated pesticide per gram of active?
Technical has no dilution, no additives, no retail packing and a lower margin chain. A formulation adds solvents, milling or granulation, testing, registration, packing and dealer margin. Do not use the technical price to judge a formulated product.
