Other national grade vocabularies (Jamaica, PNG, DR Congo, Ecuador, Yemen, Flores)

Smaller origins publish their own grade words, usually a mix of screen size and defect count. Jamaica's Blue Mountain numbers, PNG's A/X/Y letters, Congo's Kivu numbers, Ecuador's Superior/Especial/Selecto and Yemen's AA/A are the ones a buyer most often meets; all are restated here from a single importer reference chart and should be checked against each national board.
