Coffee Bean Basics: Green Coffee Trade & Sack Label Guide
If you’ve ever wondered why some countries export nearly all their coffee while others drink most of what they grow—or what those stamped codes on burlap sacks actually tell you—this guide covers the essentials. We break down global green coffee production, trade flows, and the critical details hidden in plain sight on every sack.
Quick answer: Over 70% of the world’s coffee is traded commercially, with 60kg jute sacks as the standard. Most sacks include origin, grade, and an ICO certification number (visible on the bottom line of the sack image
Where Coffee Grows: The Coffee Belt in Numbers
The world’s coffee is grown in a narrow band around the equator known as the Coffee Belt, spanning 25 degrees north and south. This zone includes over 60 producing countries, but export volumes vary widely. While Brazil consumes much of its own crop, nations like Uganda (99%), Rwanda (88%), Ecuador (79%), and Colombia (66%) export the vast majority. For some—like El Salvador and Rwanda—coffee is a critical, stable source of foreign income even during conflict.
Global Harvest Seasons by Country
Coffee production follows distinct seasonal cycles. Brazil’s main harvest runs March to October; Colombia, Kenya, Mexico, and Guatemala peak from October to March. Jamaica’s season is just August to September—the shortest of all, adding to Blue Mountain coffee’s rarity. Ecuador harvests June to October; Indonesia, May to December; Uganda, September to December. Other key periods: Haiti (October–November and February–March), Honduras (October–March), Tanzania (October–December), Zambia (October–March), and Zimbabwe (July–October).

How Green Coffee Is Traded
About 70% of global coffee production enters the commercial market, with North America and Western Europe accounting for 80% of trades. The U.S. imports a wide range of qualities but favors mild profiles; the UK and Germany rely on steady sources like East Africa; France sources heavily from Côte d’Ivoire and West Africa; the Netherlands is closely tied to Indonesia. Scandinavian countries have the highest per-capita consumption and prefer mild Arabicas, while France and Italy lean toward Robusta. Latin American markets often prefer intense, dark roasts.
The trade is regulated by the International Coffee Organization (ICO), a global body with 50 exporting member countries that control 99% of production. ICO members are split into two groups: major producers (24 countries) follow production quotas, while smaller producers are exempt. Annual coffee trade exceeds 70 million 60kg sacks, with quota countries responsible for over 90% of volume.
Green coffee is traded in two ways: physical transactions (direct buying/selling of sacks) and via futures markets in London and New York. Every sack weighs 60kg and must be labeled with origin, grade, and an ICO certificate number (for quota tracking)—you can see this code on the bottom line of the sack image .
