Published 2026 · VapeWholesaleHub trade desk

Documentation is not paperwork for its own sake; on maintenance schedule it is the difference between a clean clearance and a delayed one.

In practice the decision comes down to three numbers: unit cost, freight per unit and the realistic sell through rate for Berry 4.

• Retain one sealed sample carton from every batch for reference.
• Log sell through by account for the first eight weeks.
• Check carton quantities against the commercial invoice line by line.
• Record the arrival condition with photographs on the day of delivery.
• Verify that artwork matches the approved compliance template.
