How Tanzania’s Coffee Marketing System Works

Tanzania’s coffee trade is built around a licensing and marketing structure administered by the Tanzania Coffee Board (TCB), and understanding how that structure works procedurally is the difference between a buyer who can operate confidently in-market and one who cannot.

The default channel: the Moshi Coffee Exchange auction

Most Tanzanian coffee is sold through the Moshi Coffee Exchange, a weekly auction that runs on Thursdays for roughly nine months of the year (auctions are also held at Mbinga and Songwe). Sellers are typically Agricultural Marketing Co-operative Societies (AMCOS) acting for individual farmers or farmer groups. Only licensed exporters are permitted to bid.

Ahead of each session, the Coffee Board distributes a catalogue listing every lot on offer — supplier, grade, warehouse location and volume. Each lot has a private sample available beforehand. Before bidding opens, the Board sets a confidential reserve price for each lot in US dollars. Bidding is conducted orally and competitively; a lot is only declared sold if the winning bid clears the reserve.

Winning the bid isn’t the end of the transaction. Buyers have the right to an “outturn” check — comparing the pre-auction sample against the actual coffee held in the miller’s warehouse before taking delivery, protecting buyers against quality drift.

The alternative channel: direct export licensing

A second channel exists for top-grade coffee: the direct export licence, issued by TCB to growers or traders who want to sell premium, uniquely prepared coffee straight to an overseas buyer without going through the auction floor. The licence runs for one full Tanzanian financial year (1 July to 30 June), and every licensed direct exporter must register each transaction with the Board: coffee type, grade and class, quantity, agreed price, and an approximate shipment date, backed by a valid signed contract.

What this means for a buyer

A first-time buyer needs to decide early which channel fits their volume and quality target. Auction access requires securing a licensed exporter as counterparty, while direct export requires the seller to hold TCB’s direct-export licence and register the specific contract before shipment. Either way, the Coffee Board sits at the centre of both channels: regulator, auctioneer, and licensing authority, all at once.
