The World’s purest

All about our tea


To create the world’s purest tea, there can be no compromises.

When we say you can trust Zealong to be the world’s purest tea, that’s not just our opinion. It’s a fact. Because Zealong is one of the very few fully ISO22000 / HACCP certified tea companies.

Developed by the International Organization for Standardization, ISO22000 is the world’s highest food safety standard, and your assurance that the tea in your cup is pure and safe. To achieve this certification, we implemented systems to identify and control potential hazards at every step of the food chain. These systems are called hazard analysis and critical control points (HACCP) and include sanitisation, protecting against contaminants, regular cleaning schedules…

Our traceability system goes over and beyond industry requirements and identifies batch-specific teas by day, block, and processing method. We are certified and regularly audited by Swiss consultancy group SGS, the world’s leading inspection, verification, testing, and certification company.

So when we say we know exactly what is in our tea, and what is not, we can assure you that your next cup of Zealong tea is just that – pure tea and nothing else.
