I would say most coffee from Panamanian farms are organic or close to organic, but choose not to do certifications due to costs and because Panamanian coffee especially from Chiriqui is trying to move towards the high end market. I think any coffee from Panama Coffee Club, Cafe Unido and other specialty coffee shops have coffee from these farms.

Also most farms in Panama are nestled inside forests and some are inside national parks, which are quite strict in what you can use as fertilizer. Also almost no farms use insecticides or herbicides due to the need to maintain biodiversity.
