Technical detail worth understanding
Specification drift is the quiet risk in wholesale Bitter Vape Supply: A Buyer's Guide to concentrate sourcing — Contract Supply Guide.

Documentation and regulatory reality
The compliance burden around wholesale Bitter Vape Supply: A Buyer's Guide to concentrate sourcing — Contract Supply Guide is mostly about being boring and consistent.

Freight, packaging and landed cost
Packaging is part of logistics, not marketing. Cartons for wholesale Bitter Vape Supply: A Buyer's Guide to concentrate sourcing — Contract Supply Guide need to survive stacking, humidity and a forklift operator having a bad Monday.

Common questions
What is the usual minimum order quantity?
Minimum order quantity depends on the line. Standard stock items typically start at a single master carton, while custom work, private label artwork and bespoke tooling carry higher thresholds because the setup cost has to be recovered. We publish the figure for each line rather than quoting one blanket number.
Is there a warranty on hardware?
Hardware carries a limited warranty against manufacturing defects, covering dead on arrival and early failure within the stated period. Consumable parts such as coils and pods are excluded, as their life depends on how the end user treats them.
What shelf life should we plan around?
Unopened e-liquid is typically stable for around two years when stored cool and away from direct light, and device batteries lose capacity on a similar curve. We print manufacture dates and batch codes on every unit so stock rotation is straightforward.
