Measure a sample the way traders do: weigh a litre, count the light berries and the dirt, check the moisture, and compare with your contract.
Send these figures to our spices desk on WhatsApp for prices, samples and shipping options. See Pyalm Spices & Coffee
Pyalm trades spices, green coffee and pulses from Calicut and Dubai to Europe and worldwide, with samples, lab reports, private label and dropshipping.
Bulk density, the weight of one litre of pepper, is the quickest quality signal. Mature, well-dried berries are heavy and dense; immature or light berries and adulterants like papaya seeds pull the density down. Common trade classes include 500, 550, 570 and 580 g/L.
Light berries are immature or hollow and float in water or alcohol. Separating them from a weighed sample gives the light-berry percentage, which most contracts limit. Stalks, stones and dust make up extraneous matter.

Work out how much weight spices, coffee or grains lose (or gain) when moisture changes.
Turn a FOB or CFR spice price into CIF and landed cost per kg in your currency.
Estimate how many bags and tonnes of spices, coffee or pulses fit in a 20 ft, 40 ft or 40 ft HC container.
No. It's a quick physical check. Aflatoxins, pesticide residues, Salmonella and ethylene oxide need an accredited laboratory.
550 g/L is a common export quality, and 570–580 g/L and above indicate heavy, high-quality berries. Always use the figure in your contract.
Fill a 1-litre measure loosely to the brim, level the top without pressing, and weigh the pepper. Grams per litre is the bulk density.
