Hi Hec, Peanuts traded can be on either a screen size or on a count per ounce basis (usually the case with export peanuts) Edible groundnuts are traditionally called HPSG in trade circles HPSG is traditionally an export earner Domestic and international trade in HPSG is undertaken as per the size of the groundnuts termed as “Count”- Based on the count, kernels are classified into four broad groups; small (60-80 counts); medium (40-60 counts); large (30-40 counts); and very large kernels (20-30 counts).
