Harvest and primary processing (November–February)
Guji's main harvest runs from late October to early February, peaking in December and January. Smallholder farmers selectively pick ripe cherries by hand and deliver same-day to one of the region's washing stations in Uraga, Hambela, or Shakiso. Cherries are graded on a flotation tank to remove unders and floaters, then routed to either fully washed (depulped, fermented 36–48 hours, washed, and dried on raised African beds) or natural processing (dried whole on beds for 18–25 days with frequent turning). Honey processing is a smaller share of Guji output, typically reserved for micro-lot programs.
Dry milling and grading in Addis Ababa (January–April)
Once parchment is fully dried to 10.5–11.5% moisture, lots are bagged and transported to a dry mill in Addis Ababa or Modjo. Dry milling hulls the parchment, polishes the bean, sorts by density on gravity tables, and screens by size (typically 14, 15, 16, and 17+). Optical sorters and hand picking remove defects to meet Grade 1 (no more than three defects per 300 g sample) or Grade 2 (4–12 defects) standards. The Ethiopian Coffee and Tea Authority's quality inspectors grade and certify every export lot before it can leave the country.
Sample dispatch and buyer approval (February–June)
Pre-shipment samples — typically 300 g per lot — are sent by DHL or FedEx to prospective buyers in Europe, North America, Asia, and the Middle East. Buyers cup blind, score on the SCA protocol, and confirm purchase in writing. Once a contract is signed, the exporter holds the physical lot under the contract reference until the shipping window opens. Holding capacity at the dry mill is finite, so committed lots are released for stuffing on a first-contracted, first-shipped basis.
Contracting, documentation, and pre-export approval
The contract is signed under GCA, ECF, or a comparable template, naming Incoterm (FOB Djibouti or CIF destination), quality clause, shipping window, and payment instrument. The exporter then compiles the documentation package: commercial invoice and packing list, ICO certificate, ECTA quality certificate, phytosanitary certificate from the Ministry of Agriculture, certificate of origin from the Addis Ababa Chamber of Commerce, weight note, and the carrier's bill of lading after vessel sailing. Organic, Fairtrade, and Rainforest Alliance certificates accompany lots from certified washing stations.
Bagging, container stuffing, and the Djibouti corridor
Export-ready coffee is filled into 60 kg jute bags with GrainPro or Ecotact liners to protect cup quality during ocean transit. A standard 20-foot container takes 300–320 bags (18,000–19,200 kg of green coffee). Containers are stuffed either at the Addis Ababa dry mill or at the Modjo dry port, sealed under Ethiopian Customs supervision, and trucked across the 850 km Addis-Djibouti corridor on a 12–14 hour run. At Djibouti, containers are loaded onto vessels operated by major carriers including Maersk, MSC, CMA CGM, and Hapag-Lloyd.
Ocean transit and arrival
Transit times from Djibouti depend on the destination. Northern European ports (Antwerp, Hamburg, Rotterdam) typically receive containers in 18–22 days. US East Coast (New York, Houston) takes 28–35 days via the Suez Canal. US West Coast (Long Beach, Oakland) runs 40–48 days. East Asian ports (Shanghai, Busan) take 22–28 days. Middle Eastern ports (Jebel Ali, Jeddah) are reached in 5–10 days. Peak shipping season runs May through August, when vessel space tightens — book at least 4–6 weeks ahead during this window.
Arrival quality control and dispute resolution
Once the container clears customs at the destination port, the buyer pulls arrival samples and cups against the approved pre-shipment type sample. Moisture, water activity, and visual defect counts are recorded. Any quality variance outside contract tolerance is filed as a claim within the contractual notice period — typically 14 days from discharge — supported by an arrival cupping report and, if needed, a third-party inspection. Most disputes are settled bilaterally; unresolved cases go to arbitration under GCA, ECF, or the contract's named body.
Repeat business and seasonal planning
Roasters and importers placing recurring orders typically stagger contracts across the harvest calendar: a fresh-crop arrival in June or July for the new specialty season, a mid-year top-up in September or October, and a final stock build before the next harvest cycle. Storing green coffee in a temperature-controlled warehouse extends usable cup life to 9–12 months from shipment for fully washed lots and 8–10 months for naturals when sealed in GrainPro liners.
