Defect grading gives buyers a structured way to evaluate the physical preparation of Robusta Cambodia. The value comes from using the same sample size, categories and counting method every time.
Agree on the grading protocol
Buyer and supplier should identify the standard or internal method used for defect assessment. Different programs may classify and weight defects differently, so the contract should not simply state “low defects” without defining what that means.
Sample across the lot
One clean bag does not prove an entire shipment is clean. Commercial inspection should pull representative samples from multiple bags or positions, combine them according to a consistent procedure and record the result by lot.
Link defects to cup impact
Physical grading is a filter, not the whole decision. Some defects have a strong sensory effect; others may matter more for appearance or roasting consistency. Buyers should connect defect data with cupping results.
