Market
Green (unroasted), non-decaffeinated coffee beans are a core export-oriented agricultural commodity for Tanzania, produced as both Arabica and Robusta. The Tanzania Coffee Board (TCB) identifies Arabica as the majority share of national output and links its production to the northern slopes of Mount Kilimanjaro/Mount Meru and the Southern Highlands, while Robusta is associated with the Kagera area in the west. TCB extension materials describe a predominantly smallholder production base and a marketing structure centered on TCB’s National Coffee Auction, with an additional direct-export route for qualifying high-quality green coffees under TCB procedures. Harvest timing varies by zone, with TCB’s coffee calendar indicating July–December harvest windows in the northern and southern zones and May–October in the western zone.
Market RoleProducer and exporter (export-oriented origin market)
Domestic RolePrimarily an export commodity; domestic consumption promotion exists but the green-bean market is mainly export-linked
SeasonalityTCB’s national coffee calendar shows zone-based harvest windows, with the northern and southern zones aligned to Jul–Dec and the western zone to May–Oct.
Specification
Primary VarietyArabica
Physical Attributes- Grading is described in TCB extension materials as based on bean size/weight/density, with defect removal during milling/grading steps.
- Peaberry (PB) is specifically described in TCB materials as a single-bean cherry development trait that is graded separately.
Compositional Metrics- TCB extension materials describe drying targets around 11–12% moisture content during primary processing and storage readiness checks.
Grades- AA/A/AAA

- HP (Hand Picked defects)
Packaging- TCB extension materials describe green coffee for auction trade being packed in 60 kg bags.
- Storage guidance in TCB extension materials emphasizes clean/approved bags, palletized storage, separation from odor-contaminating goods (e.g., fuels/oils/agro-chemicals), and dry, ventilated rooms to prevent moisture uptake.
Supply Chain
Value Chain- Farm (cherry/parchment) → primary processing (wet/washed or dry/natural) → curing/dry mill (re-drying as needed, cleaning, milling/hulling, grading) → approved warehousing → TCB National Coffee Auction and/or TCB-managed direct export route → customs export processing (TANCIS) → sea shipment
Temperature- Green coffee is quality-sensitive to heat and especially moisture; maintaining dry handling and avoiding re-wetting are emphasized in TCB extension storage guidance.
Atmosphere Control- Ventilation and moisture control during storage are emphasized by TCB extension materials (e.g., ventilated, leak-proof rooms; off-floor pallet storage; avoiding night moisture re-absorption during drying).
Shelf Life- Shelf stability is primarily threatened by moisture absorption and odor contamination; TCB extension materials recommend dry, ventilated storage and separation from contaminating products.

Risks
Regulatory Compliance HighEU-bound Tanzanian green coffee faces a potential market-access block under the EU Deforestation Regulation (EUDR) if operators cannot provide plot-level geolocation and due-diligence evidence that the coffee is legally produced and deforestation-free; non-compliant or non-traceable lots cannot be placed on the EU market.Implement farm/plot geolocation capture and lot segregation, align supplier onboarding to EUDR information requirements, and run documented risk assessment/mitigation before committing EU shipments.
Labor Rights MediumThe U.S. Department of Labor’s ILAB TVPRA List includes Tanzania—Coffee under child labor, which increases reputational and compliance risk for buyers sourcing from smallholder-linked supply chains without robust due diligence.Require supplier social-compliance policies, conduct targeted third-party audits/assessments in high-risk areas, and implement remediation pathways with producer groups/cooperatives.
Climate MediumTCB sustainability/extension materials describe climate-change impacts (e.g., higher temperature and drought stress) as increasing pest/disease pressure (including coffee leaf rust) and threatening yield and quality consistency across production zones.Prioritize shade/agroforestry and soil-water conservation practices, and adopt improved/resilient varieties and integrated pest management as promoted in national extension guidance.
Logistics MediumGreen coffee export performance is sensitive to containerized sea-freight volatility and route disruptions that can raise landed costs and delay deliveries; quality can also deteriorate if transit/storage conditions allow moisture uptake or odor contamination.Lock freight bookings earlier in the season, use moisture-protective packaging/liners where appropriate, and apply strict warehouse/container inspection and dry-storage controls before loading.
Sustainability- EU Deforestation Regulation (EUDR) compliance for coffee: deforestation-free and legal production claims require plot-level geolocation and due diligence for EU-bound supply chains.
- Wet-processing environmental controls (e.g., wastewater handling) and broader climate adaptation needs are addressed in TCB sustainability/extension materials.
Labor & Social- Child labor risk in coffee supply chains: the U.S. Department of Labor (ILAB) TVPRA List includes Tanzania—Coffee under Child Labor, requiring heightened buyer due diligence for smallholder-linked sourcing.
FAQ
When is green coffee typically harvested in Tanzania?TCB’s coffee calendar indicates harvest windows of July–December for the northern and southern coffee zones and May–October for the western zone (Lake Victoria/Kagera area).
How is Tanzanian green coffee commonly marketed for export?TCB extension materials describe marketing channels including farm-gate sales to licensed buyers, a TCB-organized National Coffee Auction where traders bid on green coffee, and a direct-export route for qualifying high-quality green coffee lots that requires a specific TCB direct-export authorization.
What is the biggest EU market-access risk for Tanzanian green coffee?For EU-bound shipments, the EU Deforestation Regulation (EUDR) is a key constraint: operators must have plot-level geolocation and due-diligence evidence that coffee is legally produced and deforestation-free; products that do not meet traceability/compliance requirements cannot be placed on the EU market.
