Tea Processing Plant Project Report (DPR) 2026

What is tea processing?

Tea processing converts the fresh shoots of Camellia sinensis into a shelf-stable dry product, known in the trade as made tea. Leaf starts to deteriorate soon after plucking, so factories sit close to the fields, and growing and processing are usually a single regional business rather than separate global ones.

How far the leaf oxidizes defines the product. Black tea is fully oxidized and is made either by cut-tear-curl (CTC) machines, which give the strong, fast-brewing grades favored for tea bags, or by the orthodox rolling method, which keeps whole leaf and commands higher prices. Green tea is heated early to stop oxidation, and oolong sits between the two.

Buyers include blenders and packers, auction traders, instant tea and ready-to-drink makers, and retail brands. Made tea falls under Harmonized System heading 0902. Bulk black tea, the largest item for a factory of this kind, is subheading 0902.40, and bulk green tea is 0902.20. Packs of up to 3 kg move to 0902.30 and 0902.10, and instant tea is classified separately under 2101.20.

Tea market overview and global demand

Credence Research values the global tea market at USD 121.35 billion in 2023, with a 5.5% CAGR through 2032. That implies about USD 135 billion in 2025, a figure derived from the 2023 base and growth rate. The value covers finished tea at consumer-facing levels, so it sits far above what factories earn for bulk made tea.

The physical market is much smaller in money terms. FAO's tea market review puts world output at 6.7 million tonnes in 2022, with China at 3.34 million tonnes, India at 1.37 million and Kenya at about 543,000. Consumption reached 6.5 million tonnes, growing 3.3% a year over the prior decade, with China and India together taking about 64%. FAO projects green tea output growing about 6.3% a year to 2032, and black tea output about 1.6%.

Most tea is drunk where it grows, so exports were only 1.84 million tonnes in 2022. UN Comtrade records for 2024 show about USD 7.3 billion and 1.94 million tonnes of reported exports under heading 0902. China, Kenya and Sri Lanka each shipped about USD 1.4 billion, followed by India at USD 0.8 billion. Their unit values explain the industry's main divide: Kenya averaged about USD 2.25 per kg, India USD 3.22, China USD 3.79 and Sri Lanka USD 5.73.

Pakistan, Russia and the U.S. were the largest importers in FAO's review. Prices remain under pressure for now. The Kenya tea Development Agency cited a global slump and lost sales to Iran and Sudan in February 2026, and Sri Lanka's first-half 2026 auction average fell to USD 3.66 per kg from USD 3.89 a year earlier. Oversupply of plain black tea is therefore the central risk, while premium and specialty lines are where buyers still pay more. Readers can compare value-added demand in the ready-to-drink tea study.

Tea manufacturing process

A factory has little time to fix mistakes. Leaf quality at intake sets the ceiling on final price, and each later stage can only protect that quality or lose it. Fine plucking raises the grade, while coarse or bruised leaf sells at a discount.

• Leaf intake and weighing. Growers' leaf is received, weighed, graded and moved quickly to the troughs, since heat builds up in packed loads.
• Withering. Leaf rests in troughs for about 8–12 hours while fans blow air through it, removing water until moisture falls to about 70%.
• Rolling or CTC. Orthodox lines twist leaf in rollers. CTC lines pass it through a rotor vane and serrated rollers, which rupture the cells and start oxidation. Green tea is steamed or pan-fired first, which prevents oxidation.
• Oxidation. Often called fermentation in the trade, this stage lets enzymes and oxygen develop color and body on floors, beds or continuous fermenters under humid conditions.
• Drying. Hot air at about 90–110°C in endless chain dryers, or 140–160°C in fluid bed dryers, halts oxidation and brings moisture to low single digits for storage.
• Sorting, grading and packing. Vibrating meshes and fiber extractors split tea into leaf, fannings and dust grades, packed in multi-wall paper sacks for auction or direct sale.

Fuel is the largest conversion cost. An energy audit of an Indian factory recorded 5 kg of green leaf per kg of made tea and total use near 9.5–10 kWh per kg, with about 95% of it thermal. Firewood, coal, gas and biomass are all in use, so a dependable, legal fuel source shapes siting.

Tea processing plant setup cost

This overview models a greenfield CTC factory with some orthodox capacity, rated at 2,500 tonnes of made tea a year, with an estimated CapEx of USD 4–9 million. Tea fields, woodlots and working capital are excluded, because their cost varies with who owns the leaf.

The range rests on disclosed factories, each scaled with a standard capacity exponent. The Kibeho factory in Rwanda was reported at more than EUR 5 million for 150 tonnes of leaf a day, which scales to about USD 3 million at the model's roughly 65-tonne peak. Sorwathe's USD 1.12 million, 300-tonne organic green tea factory, opened in 2018, scales to about USD 6 million in current money. Kenyan projects sit in between, with Kiptere budgeted at 960 million shillings, about USD 6 million, and Madala allocated 700 million shillings, about USD 5.4 million, though neither discloses rated capacity.

The floor of USD 4 million adds site utilities to the lean African builds. The USD 9 million top assumes about a 1.5 times premium on the Kenyan and Sorwathe scale for tighter emission controls, automation and higher-cost construction, a judgment rather than a disclosed figure. Basic cooperative plants can cost far less: a Vietnamese cooperative plans a 900-tonne unit for about USD 535,000, which this overview judges a simpler specification.

Worked example, land and site development. Kiptere uses 12 acres, about 49,000 square meters, so the model takes an assumed 20,000–40,000 square meters. At an assumed USD 10–30 per square meter in a tea-growing district in Africa or Asia, land costs USD 0.2–1.2 million, or an assumed USD 30–80 at a U.S. or EU site, USD 0.6–3.2 million. Site works add an assumed USD 0.1–0.3 million, so this row runs about 7–17% of CapEx in tea-growing regions.

Green leaf dominates operating cost, well ahead of fuel, power and labor. Exact line items and cost sheets remain in the full report, which can be customized to any country's land, fuel and wage costs.
