Belgium ·
Tessenderlo Group is a diversified industrial group headquartered in Belgium and listed on Euronext Brussels. The company describes itself as an industrial group that focuses on agriculture and on valorising bio-residuals. Its Agro segment brings together the production, sales and marketing of crop nutrients and crop protection, while other segments cover industrial products such as plastic piping. Tessenderlo Kerley, known for its sulphur fertilisers, is part of the group.
On the farm, Tessenderlo's agricultural business is best known for sulphur fertilisers such as Thio-Sul and KTS. Sulphur is a nutrient many crops need alongside nitrogen, and a shortage can limit both yield and quality, particularly in oilseeds and cereals grown on light soils. Choosing between these products depends on the crop, the soil analysis and the application programme, so the composition and local recommendations for each product matter more than the brand name.

## Size of the business

Tessenderlo's Agro segment had revenue of EUR 935.1 million in 2025; the group also has industrial businesses outside agriculture.

### What does the company offer?

Through Tessenderlo Kerley, the group offers sulphur fertilisers such as Thio-Sul and KTS together with wider crop nutrition solutions. Its Agro segment also includes crop protection.

### How should a buyer make contact?

Sales are organised by country and business unit, and the company website lists the local contacts for each market. Enquiries are handled fastest when they describe the intended use, the size of the project and the timing required.
