Tobacco product costing: moisture makes the consumption figure move
Batch costing as in food processing, plus one thing of its own — raw material weight changes with moisture, so consumption has to be normalized to a common basis before any two batches compare.
The cost structure matches **food processing**: batch production, a chain of losses through the process, cleaning charged per changeover. Read that guide first — it covers nearly the whole sheet.
One difference is small in appearance and breaks every comparison if ignored.
The same material, two different weights
Agricultural raw material carries water, and how much varies by lot, by season and by how it was stored. So **weighing two lots at two moments gives two different weights for the same amount of dry substance**.
The consequence for the sheet: consumption calculated on as-weighed mass jumps between lots, and nobody can tell whether you used more material or the lot was simply wetter.
This is the clearest example of a general principle: a figure is comparable only when the reader knows what state it was measured in. Record the basis and your sheet compares with other plants; omit it and the sheet is usable only by you.
Two changes from the food guide
| Category | What changes |
|---|---|
| Material | Consumption normalized to a common moisture basis; loss chain as in food processing |
| Packaging | More layers and a much larger share than ordinary food products — keep it as several lines rather than one |
The remaining eight follow the food processing guide, including cleaning between batches and the rule that expired stock is an inventory loss rather than production scrap.
