The top tea producing countries are India, China, Kenya, Sri Lanka, and Indonesia, while the top consuming countries are India, China, Japan, the UK, and Russia/CIS. The supply of tea has traditionally exceeded demand and tea is a non-competitive commodity. Factors affecting demand include price, income, tastes, and expectations, while factors affecting supply include production costs, expectations, input prices, number of suppliers, and policies.
