"Third repeat order this year. Documentation was on our desk before the vessel sailed and moisture on arrival was inside spec. Their QA sheet matches what actually lands in the container — that's rare."

"We audit every India supplier annually. Prasangi cleared APEDA and our internal pesticide-residue test on the first pass. Communication in English is direct, no back-and-forth on Incoterms."
"Switched to Prasangi after two years of inconsistent grading elsewhere. Samples matched shipment 1:1. Payment terms were fair and they held the price when the market moved against them."
