The production stood at 1115.88 million kg in the April-December period of the last fiscal, according to Tea Board data.
Assam and Bengal together contribute more than 85 per cent of the country's total tea production.
Output took a hit this fiscal mainly due to unfavourable weather conditions. Besides, wage-related issues also hit tea producers.
The sector has also been facing other issues including migration of labourers to other industries.
However, the exports surged 9 per cent to Rs 3,218.07 crore in the first nine months of the current fiscal from Rs 2,955.78 crore in the year-ago period.
India, the world's second biggest tea producer, exports CTC (crush-tear-curl) grade mainly to Egypt, Pakistan and the UK, and the orthodox variety to Iraq, Iran and Russia.
