The Classic Thai Tea Leaf, 400 g, is produced by a tea factory with more than 30 years behind it, and the producer states its quality is guaranteed to the GHPs & HACCP standards.
The same product is certified Halal.
Both certifications belong to that one product — Classic Thai Tea Leaf, 400 g. No certification information has been supplied for the other drinks, so no certification mark is printed on their pages at all.
The 500 g extract and the 3-in-1 sticks have full specs and directions, but no certification came with them. Those are separate things: having a spec is not the same as carrying a certification.
What the producer does state clearly for the 3-in-1 sticks is the allergen line: they contain milk products. That line appears on every 3-in-1 product page.
