द्विगुणं रसादीनां मानमूल्यम् ॥ कZ_०२.१९.३७ ॥
dviguṇaṃ rasādīnāṃ mānamūlyam
For liquids such as juices (rasādayaḥ), the fee/value fixed for measuring (māna-mūlya) shall be double.
Liquids require tighter control (leakage, evaporation, adulteration risk) and more frequent verification of containers; a higher official fee funds oversight and discourages informal, unverified measures.
