Black tea is the most common, most exported, and most consumed type of tea in the world, while white tea is the least?

Black tea is indeed the most produced, exported, and consumed tea globally, accounting for about 75-80% of world tea production. It has the longest shelf life and is most suitable for international trade. White tea, being the least processed and most delicate, is produced in smaller quantities and is less common in global trade. This makes it the least common among the four main types in terms of commercial availability and consumption volume.
