Published 2026 · VapeWholesaleHub trade desk
Airflow tuning is the single adjustment that changes how Stark 4 feels in daily use.
Buyers who treat airflow tuning as a commercial discipline rather than an afterthought tend to hold margin for longer.
A written internal standard for airflow tuning makes onboarding new account managers far quicker and reduces avoidable errors.
Why airflow tuning matters on the Stark 4
Restricted airflow suits mouth to lung customers moving from traditional products.
In practice the decision comes down to three numbers: unit cost, freight per unit and the realistic sell through rate for Stark 4.
Open airflow serves direct lung users who prioritise vapour volume.

Commercial terms
Freight terms should be named explicitly, because an unclear incoterm is the fastest way to lose a relationship.
Lead times are a function of component availability as much as factory capacity, so buffers should reflect both.

| Pallet (579 units) | Tier 2 | 14-21 days |
| Container (5949 units) | Tier 3 | 7-12 days |
