Airflow tuning is the single adjustment that changes how Passage 4 feels in daily use.
A range review that ignores airflow tuning will often produce a confident decision and a disappointing quarter on the Passage 4.
In practice the decision comes down to three numbers: unit cost, freight per unit and the realistic sell through rate for Passage 4.
Why airflow tuning matters on the Passage 4
Restricted airflow suits mouth to lung customers moving from traditional products.
Shops that receive a short briefing on airflow tuning convert noticeably better than shops that only receive stock.
Open airflow serves direct lung users who prioritise vapour volume.

Seasonality interacts with airflow tuning more than most forecasts allow for, so a rolling review beats an annual one.
Documentation is not paperwork for its own sake; on airflow tuning it is the difference between a clean clearance and a delayed one.
Checklist
- Confirm the exact configuration in writing before the deposit is paid.
- Review the reorder point after one full selling cycle.
- Verify that artwork matches the approved compliance template.
- Request batch photographs and a packing list prior to shipment.
- Check carton quantities against the commercial invoice line by line.

Commercial terms
Freight terms should be named explicitly, because an unclear incoterm is the fastest way to lose a relationship.
Agreeing a defect handling procedure before the first shipment removes emotion from later conversations.
