Tea Processing and the Role of Bought Leaf Factories (BLFs) for Small Tea Growers (STGs)

However, BLFs face several issues. The quality of green leaves deteriorates with longer transit times to factories, leading to damage and flavor loss, and preventing STGs from getting remunerative prices. STGs often depend on local leaf agents for transportation, who act as intermediaries and exploit STGs by determining price and quality, taking a large share of the profits. These agents collect leaves from multiple small growers, as individual contributions are insignificant for BLFs. While BLFs provide a market for STGs, they have also fostered the growth of middlemen, who control local markets.

Unlike the integrated management system of the estate sector, where production and processing are unified, the BLF system involves independent small growers and factories, creating a decentralized structure. Although BLFs typically compete based on the volume of green leaves, this decentralized model sometimes compels them to maintain close contact with STGs and monitor quality standards to ensure higher auction prices for their tea.

The second key stage in tea production is processing green tea leaves into 'made tea'. Small Tea Growers (STGs) often engage in 'plunder plucking' to maximize volume. Unlike large tea estates with their own processing factories, STGs supply their plucked leaves to Bought Leaf Factories (BLFs) or, less frequently, to estate factories. BLFs blend the tea and rely solely on small growers for their raw material, as they do not own plantations. A study by Hannan (2013) indicated significant STG dependency on leaf agents, ranging from 8.3% in Kerala to 44.2% in Assam.

The actual economic exchange between cultivators and the industry frequently occurs at BLFs. Initially, in India, 162 BLFs produced 67.01 million Kg of made tea. In West Bengal, there were only six BLFs in 2000, which expanded to 46, collectively producing 16.9 million kg. By 2002, this nearly doubled to 33.57 million kg from 62 BLFs, and by 2004, the numbers reached 79 BLFs producing 49.5 million kg. The growth of tea production outside the traditional estate sector in West Bengal was rapid until 2002, particularly fast in the Terai region, where BLF production rivaled estate factories. Currently, about 167 BLFs in the region produce approximately 130 million kg of tea.
