A tea's price is set twice, and the two settings rarely agree. The first is the auction or private-sale price a garden receives for a given lot: fixed at one moment, by grade and origin, against whatever else is on offer that week (the mechanism is The Auctions; the chain it feeds is How the Trade Works). The second is everything that happens to that same kilogram of value after the gate: currency conversion, export levies, certification premiums, and the long march through blender, packer, and retailer margin before it reaches a shelf. This reference documents both settings: what fixes the price at the point of sale, the long-run trend in what that price is actually worth, where the money goes once the leaf clears the garden gate, what moves the price between one sale and the next, and what a certification label changes and does not change.

What fixes a price at the point of sale

Three things decide what a given lot fetches at auction, and none of them is a judgment about whether the tea is "good."

• Grade. A tea's grade is a leaf-size classification, not a quality score, and it is the single most reliable price signal in the trade. At the Guwahati Tea Auction Centre in Assam, whole-leaf Orthodox tea has sold at close to a 25 percent premium over machine-cut CTC and Dust grades from the same region, a gap set by what a buyer needs (a slow-brewing whole leaf for a loose-leaf tin, a fast-brewing granule for a bag), not by which tastes better. The full grading hierarchy, OP through Dust, and the CTC-versus-Orthodox manufacturing split behind it, is documented in A Tea's Grade Is a Size Code, Not a Quality Score.
• Origin and season. The same grade sells for different prices from different origins and different flushes of the same garden, because buyers are pricing a cup, and cups differ by terroir and by which flush of the year produced the leaf. A first-flush Darjeeling lot can sell for many multiples of a later flush from the identical garden, a gap the auction record shows clearly and that the season's bulk income rarely follows (see the Darjeeling case for how far that split can run).
• What else is on the table that week. An auction is a live clearing mechanism: a lot's price depends on the buyers bidding against each other and against every other lot of comparable grade and origin on offer that same session, not against some fixed reference value. The same tea can fetch a different price a month later purely because the mix of competing lots changed.

Grade and origin set the ceiling and floor for a given lot; the week's supply and demand decides where inside that band the hammer falls.

The long arc: real terms, not nominal

Read a decade of auction-price tables and tea looks stable: composite prices across Mombasa, Kolkata, and Colombo have held in a narrow nominal band for years. That stability is an illusion created by inflation. Asked in 2022 to summarize two decades of the market, Ian Gibbs, chairman of the International Tea Committee, the body that has tracked auction prices since the 1930s, put it in one line: over the prior twenty years there had been no real movement, and tea's price, once inflation is stripped out, sat below what was paid a century earlier. The nominal number barely moved across that whole stretch; the real one quietly eroded the entire time.

The mechanism behind the erosion is on the supply side, and the FAO's own reporting to its Intergovernmental Group on Tea has tracked it across successive market assessments: production has grown faster than demand, decade after decade. Smallholders, who by the International Institute for Sustainable Development's 2024 accounting now grow roughly 60 percent of the world's tea and make up two-thirds of a sector employing some 13 million people, keep adding plantings because tea is one of the few cash crops a small plot of land can grow, a rational choice for any one grower trying to hold income steady on a falling price. Summed across millions of growers making that same rational choice, it adds supply to an already oversupplied market, which is exactly the condition that holds a real price down for a generation rather than letting it recover on its own. World consumption has kept rising over the same stretch, driven mostly by China and India's own growing domestic markets, but supply has simply grown faster, and the auction floor is where that mismatch settles.

Every input to growing and processing tea (fuel, fertiliser, labour, transport) has risen with general inflation across that same period, while the auction price has not kept pace. The result: a grower's income, set almost entirely by a number the grower does not control, has gone nowhere in real terms for a generation, while the finished product a shopper buys is insulated from that erosion by a retail price point that is far stickier than any commodity floor.

Where the money goes after the gate

The price a garden receives at the gate and the price a shopper pays at the shelf are set by entirely different mechanisms, and the gap between them is the sharpest fact in the whole trade. Two field studies of the same question, run two years and one continent apart, put real numbers on the split, and disagree with each other in an instructive way. The fullest treatment of both, with the arithmetic worked through, is Who Makes Money From a Cup of Tea?; this section carries the reference figures.

The Assam and Vietnam rows are not on the same footing, and the mismatch matters: the Assam study's grower and collector figures are priced per kilogram of green leaf, the raw pluck, while its factory, wholesaler, and retailer figures are priced per kilogram of made tea, the finished product; it takes roughly four kilograms of green leaf to produce one kilogram of made tea. Put on a made-tea-equivalent basis, growing and collecting together net Assam's smallholders somewhere near Rs 18 a kilogram against the factory's Rs 20.00, a real gap but a modest one, not the four-fold difference the raw per-unit figures suggest at first look. The processing step still captures the largest single cut on that corrected basis, ahead of the land, but by a margin, not a multiple. The 2021 Thai Nguyen study, measured consistently in net-added-value share throughout, found close to the opposite structure: farmers captured the highest share of the chain's net value, more than the processor and more than thirteen times the collector's share. The two studies agree on exactly one thing worth generalizing: the split is not fixed by anything intrinsic to tea. It is set by how many hands a given country's leaf passes through on the way to a cup, and how much leverage each pair of hands holds in that particular chain, which is why a value-chain finding from one origin cannot be assumed to hold in another.

What both chains share is where the widest single margin usually sits: not at the farm gate, and not, in most markets, with the grower at all. Brands and supermarkets typically take the largest share of what a packaged box of tea sells for, while the estate that grew and plucked the leaf keeps a share in the low single digits, out of which it still pays its workers. That squeeze shows up past the value-chain arithmetic too: Hindi-language reporting on Assam's tea belt, coverage an English-only reading of the trade press would miss, records delayed wage payments and a minimum daily wage that trails other Indian states as a standing complaint in the gardens, alongside calls in that same coverage for government relief to address it. The imbalance is structural rather than a market failure in any one country: a grower's income is set almost entirely by a commodity price it does not control, while a blender, packer, or retailer sets its own margin on a finished, branded product at a price point that barely moves with the auction floor underneath it.

What moves it between one sale and the next

Grade and origin set where a lot sits in the price band; three further forces move the whole band up or down between sales, and none of them behaves the way intuition suggests.

• Currency. Tea is grown and plucked for wages paid in the grower's own currency, then sold, in most major markets, against the US dollar (Mombasa, the world's largest tea auction, has settled every trade in dollars since October 1992, a rule adopted to give buyers a single stable unit across the several African origins it clears, not to shield growers from exchange-rate risk). Whatever the dollar does against the grower's currency between the sale and the payout lands, in full, on the grower's income, in either direction, for reasons that have nothing to do with the harvest. In the 2024/25 season, a strengthening Kenyan shilling alone cost tea growers about 15 shillings on every dollar of revenue, enough to erase a season's bonus even while the dollar auction price itself held steady (see What a Weak Currency Does to a Tea Garden's Earnings).
• Weather. A drought or a storm does not reach a price tag directly; it has to travel a chain, bush to pluck to factory to auction floor, and what happens at the last link, a global auction where buyers can often simply bid on another origin's tea instead, usually decides more than the weather event itself. Recent droughts in Kenya and Assam and a major cyclone in Sri Lanka have each moved the price differently, sometimes not raising it at all, because a shock is a volume problem, a logistics problem, or neither, and each type clears the auction floor differently (see Why a Drought Doesn't Always Raise the Tea Price).
• Export levies. A government does not need to own a garden to take a cut of the crop; it only needs the point where made tea crosses the border. Kenya taxes that moment at 0.8 percent of sale value as of its Tea (Levy) Regulations, 2026; Sri Lanka has taxed it, at a shifting rate, since the 1970s; India taxed it for over a century before dropping the charge. Who pays a border levy on paper and who absorbs it in practice are frequently different questions, since the incidence can shift back up the chain to the grower depending on how much bargaining power each origin's producers hold (see Who Pays the Tea Tax?).

Certification and the premium price

A certification label is a promise about money: that a grower somewhere was paid something extra for that specific leaf, over and above the ordinary market price. The two largest schemes price that promise very differently.

The gap between certified and paid is the load-bearing fact here. Certification guarantees a garden the right to an extra payment; it does not guarantee a buyer willing to make it, which is why the large majority of certified tea, under either scheme, still clears the market at the ordinary price. A flat 50-cent Fairtrade premium, applied only to the sliver of production that actually sells on those terms, does not reach far into a value chain where the estate nearest the leaf typically keeps a share in the low single digits of the final retail price. It is real money where it lands. It is not, by itself, a fix for the structural split documented above (see What a Certification Label Actually Pays the Tea Grower for the full figures, including Kenya's 2025 attempt to opt certain factories out of the compliance cost entirely).

Two structures the market does not have

Two features that a reader familiar with other commodities might expect are both, deliberately or by history, absent from tea.

• No futures market. Coffee has traded futures since 1882 and cocoa since the 1920s. Tea, which outsells both, has never had a liquid futures contract anywhere. The cause is standardization, not stability: a futures contract needs a single deliverable unit that still means the same thing on the delivery date as it did when the contract was written, and no two lots of tea are fungible that way. Grade, origin, season, and even the specific garden all shift what a lot is worth, so there is no single standardized deliverable a contract could specify, and multiple exchange attempts have failed for exactly that reason, a problem the FAO's own Intergovernmental Group on Tea has documented directly. A shorter explanation sometimes offered, that tea's supply is simply too predictable to need a hedge, does not hold up against the auction record above: droughts, monsoons, and a cyclone have each moved the price, in different directions, which is not the behavior of a commodity too stable to insure against (see Why Doesn't Tea Have a Futures Market? for the full case, including two 2020 academic proposals for a workable contract).
• No cartel since 1955. Tea has had no coordinated supply-restriction mechanism since 1933 to 1955, when India, Ceylon, and the Dutch East Indies ran a legally binding export-quota cartel that did restrict planting and did move the price, sharply, before it lapsed and was never revived. The Intergovernmental Group on Tea is the one standing body where producing and consuming governments discuss the market today, and it has laid out the supply-and-demand mismatch above in detail without arriving at any binding mechanism to correct it (see The Tea Cartel That Worked).

Both absences point the same direction: nobody, and no mechanism, currently holds the supply side of tea's price the way OPEC holds oil's or a cartel once held tea's own. Millions of smallholders each making an individually rational planting decision, in a market with no coordinating body and no way to hedge the risk forward, is why the real-terms decline documented above has run as long as it has, and why nothing in the current structure of the trade is positioned to reverse it on its own.
