Published 2026 · VapeWholesaleHub trade desk
Leak prevention is a quality issue that shows up in return rates long after the first order.
What follows is a practical view of leak prevention for the Nex, written for people who place repeat orders rather than one off buys.
In practice the decision comes down to three numbers: unit cost, freight per unit and the realistic sell through rate for Nex.
Why leak prevention matters on the Nex
Consistent filling torque and proper sealing rings remove most transit leaks.
Keeping a short internal note on leak prevention for each SKU pays for itself the first time a dispute arises over the Nex.
Pressure changes during air freight are a common cause of minor seepage.

Frequently asked questions
How can leakage in Nex shipments be reduced?
Use sealed inner trays, keep cartons upright and allow a settling period before retail display.
Can packaging be adjusted for our market?
Artwork localisation is straightforward; structural changes need larger volumes and a longer lead time.

The agreed procedure normally covers replacement of affected units or credit against the next order, documented before shipment.
