Specialty chemicals & trading
Importers, distributors and blenders handling hazardous and non-hazardous chemicals, buying in bulk currency and selling in drums, cans and small packs.
Landed cost is discovered after the container clears, and repacking from bulk into retail packs is a conversion nobody accounts for, so pack-level margin is unknown. Batch and MSDS documentation lives outside the stock record.
Landed cost vouchers apportioning freight, duty and clearing back to the item, repacking modelled as a stock conversion so pack cost is real, and batch attributes with document attachment held against the lot.
