Why are the enzymes in biofase measured in MG and not in FCC (Food Chemical Codex)?

Shouldn't the enzyme activity of products be measured and reported in FCC units?

These unit measurements are usually expressed as follows:

Protease - HUT (Hemoglobin Unit Tyrosine base), USP
Amylase - DU (Alpha-amylase Dextrinizing units)
Lipase - FIP, LU, FCCLU
Cellulase - CU (Cellulase unit)
Invertase - IAU (Invertase Activity unit)
Lactase - LacU (Lactase unit)
