In practice: checklist
- Count AL as saleable goods plus goods transferred as precursors; exclude scrap, off-spec and waste.
- Measure precursor input (Mi) where it enters the process, before cutting or trimming.
- Calculate ae, mi and SEE per CN code (or mandatory group) for the year.
- Look up your country's default value, add the mark-up, and compare with your actual SEE.
- Keep at most 5 decimals in SEE and round yearly totals to whole tonnes.
