What We Stand For

Tea Passport

As the farmers all of our teas come with a Tea Passport. Our Tea Passport is a code of conduct endorsed by a number of third party certification bodies. This guarantees a unique and distinctive quality in our tea manufacture, which produces truly sustainable and ethically produced tea under the guidance of the Williamson Tea Foundation.



Everyone who has a cup of Williamson tea makes a difference to ensure future generations can enjoy wild forests, fertile soils, elephants and truly sustainable tea.


Terra Carta

We are proud to be standing and committing to the statements of the Terra Carta putting nature, people and the planet first.

Launched by His Royal Highness The Prince of Wales to mark the start of the new decade The Terra Carta aims to reunite people and planet. By giving fundamental rights and value to Nature and putting sustainability at the centre of business we can ensure a lasting impact and tangible legacy.



Our Tea

Rainforest Alliance

The little green frog is recognized by consumers around the world as the symbol of environmental, social and economic sustainability. Rainforest Alliance’s comprehensive farm-management standards and traceability system help to ensure that products bearing the green frog seal can be traced back to well-managed farms that protect workers, wildlife and communities. Williamson Tea was one of the first tea producers in the world to be certified by the Rainforest Alliance.




Soil Association

The Soil Association is one of the largest and most well respected organic certification bodies in the world. In 1967 it developed the world’s first organic certification system, putting stringent standards of organic production into practice, principles of producing good food that protects the natural world. All products certified by the Soil Association comply and exceed the EU Organic Regulations as a baseline and in fact go far beyond these standards, giving consumers confidence that organic teas produced on Williamson’s farms are produced to the very highest standards in the world.



Japan Agricultural Standards

Williamson Tea’s organic teas meet Japan Agricultural Standards (JAS). This additional standard allows products to be marketed as organic within the Japanese market, adding value to Williamson Tea products by opening up new opportunities for customers businesses.



ISO 22000

ISO 22000 is a Food Safety Management System that can be applied to any organization in the food chain, farm to fork, or in our case ‘bush to cup’. ISO22000 demonstrates Williamson Tea’s food safety management system, giving customers confidence in the quality and safety of the teas produced.



BRC certification is an internationally recognized mark of food safety and quality. Certification is achieved by undertaking a third-party audit against Standard requirements by an accredited certification body. Williamson Tea’s branded products are produced to BRC certification within the UK.
