The most significant quality issues are regarding moisture level -> 8-9% ideal, 10% is max, and 13% is hazardous for the crop(Shelf life is one year). The beans' moisture level is checked at every stage of the value chain.
There are a few logistical issues (e.g., shipping containers) as the beans are dried. The dried condition allows a long shelf-life for the product, lowering the risks of shipping and storage issues.
