Tessenderlo Kerley Formulators - the edge in bringing products to market

Tessenderlo Kerley Formulators became part of Tessenderlo Kerley in 2007, offering toll-processing formulation and secure warehousing to expedite customer manufacturing and marketing.
Started in 1992, the group has considerable expertise in chemical formulation and packaging, specializing in agricultural, home and garden, PCO and industrial products. Because choosing the right toll operation can result in customer success or failure, TK Formulators focuses on satisfying the stringent requirements of the most discerning technology
owner. TK Formulators maintains toll manufacturing contracts with several major pesticide producers.
TK Formulators' 20-acre plant site is strategically located in central California in the agricultural heart of the San Joaquin Valley. Storage space includes 100,000 square feet of flat storage and 2.5 million gallons of liquid storage — 750,000 of those gallons are stainless steel.

TK Formulators offers a fully equipped and staffed QA laboratory capable of complex analysis based on customer-provided methods. The lab is capable of performing analyses for active ingredient, heavy metal and moisture content by liquid or gas chromatography, atomic absorption (AAS), and coulometric titration (Karl Fisher) methods.

TK Formulators' formulation capabilities are wide and varied with a vast knowledge and experience base in insecticides, herbicides, fungicides and industrial products.
