The brainchild of – founding FOSFA member, pharmacist, chemical engineer, scholar and analyst – A. Norman Tate & Co Ltd has built up an enviable pedigree and leading analytical know-how over more than 140 years.

In 1867, after making a name for himself in the UK chemicals and refining sectors, A. Norman Tate opened his own laboratories in Liverpool. Soon, Tate was managing one of the country’s most extensive chemical practices, specializing in waters, alkalis, petroleum, mineral oils and oils & fats.

The company continued to expand into the 20th century, in new sectors such as oilseeds, soaps and associated industries, and in new infrastructure and dockside offices. Tens of thousands of samples passed through the laboratories every year in the 1920s. The 1930s decline and WWII temporarily depressed the market, but, by the 1950s, business was flourishing again.

The product analysis portfolio continued to grow – from a focus on West African palm kernels, palm kernel oil, palm oil and sheanuts in the 50s, the company diversified into the analysis of soya beans, sunflower and sesame seeds, linseed and rapeseed analysis in recent times. Client numbers and requirements increased so much that the company had to relocate to larger premises in Bootle, just north of Liverpool city centre.

A. Norman Tate & Co Ltd joined the Alex Stewart Agriculture Group in 2004. The company continues to provide sector-leading FOSFA accredited inspection, analytical and laboratory services to clients around the world from its Aintree, Liverpool laboratory.

Few analytical or laboratory specialists can claim such an impressive pedigree as. As a fully integrated partner of Alex Stewart Agriculture, fewer still can match its modern agricultural and soft commodity analysis portfolio.

Thomas and Charles Huson set up Huson Brothers in 1846 to serve manufacturers of industrial and agricultural chemicals in and around Liverpool. Business flourished as the Port of Liverpool became one of the world’s largest import/export operations. Traders and industrial concerns relied on the expertise on offer to assess product quality and settle disputes. Chemistry graduate William Hardwick became a partner in the early 1900s – and Huson & Hardwick was born. Soon, the company had long-term analysis and consultancy contracts with the Liverpool Tate & Lyle factory, Unilever and several other high profile brands in the cane sugar, molasses and groundnut and palm kernel sectors.

Huson & Hardwick expanded into animal feeds, oils & fats, oilseeds, pet food and human foods in the late 1960s and by the mid-80s had also established a leading position in the analysis of such commodities as sheabutter and rapeseed. In 2000, Huson & Hardwick joined the Alex Stewart Group’s new agricultural section. Lines of analysis perfected over decades have been updated for the 21st century.

Today, the laboratory offers a comprehensive range of GAFTA, FOSFA analysis and also UKAS 4352 certified testing services. More than 150 years after its formation, Huson & Hardwick continues to innovate, to lead the way in the provision of cutting-edge analytical and certification services. Both A. Norman Tate and Huson & Hardwick laboratories are independent and wholly owned subsidiaries of Alex Stewart Agriculture Limited.
