I hope this is helpful. Here is some more detailed information on the common specifications for whole black pepper:

Size: Typically 2.5 to 7.0 mm in diameter, with a globular shape and wrinkled pericarp.
Color: Black or brownish-black.
Moisture Content: Typically, the moisture content should be no more than 12%.
Purity: Should be at least 99% pure.
Foreign Matter: Less than 0.5% of foreign matter.
Bulk Density: Can range from 500 to 550 g/l.

Here’s a more detailed look:
