The batch moves
Harvests change. So do drying runs and lab results. Each batch after the first is re-checked against the intake standard the processor accepted, and against what the operating record already declares. That record is concrete. BfArM’s trader guidance requires every cultivar to be listed separately on the trader’s permit, and holds an extract’s THC content to within ±10% of its declared value.
