The heading separates them at the HS6 level: non-decaffeinated green coffee falls under 090111, while decaffeinated green coffee falls under 090112. The decaffeination process — regardless of method (water, solvent, or CO₂) — is the sole criterion for the split; roast level is a separate dimension addressed by the 090121/090122 distinction.

Coffee husks, skins, and cascara (the dried skin of the coffee cherry used to make herbal tea) fall under subheading 090190, which also covers coffee substitutes containing coffee. Herbal teas made from coffee cherry skin are classified here rather than in the tea heading (0902), because the botanical source is Coffea rather than Camellia sinensis.
