Questions we are asked about TPD compliance

Does Vape Sourcing e-liquid need any accessory to be usable on day one?

In most cases no, it is usable straight away once charged or filled. The two things worth adding at the point of sale are a spare coil or pod and, for removable-cell devices, a proper storage case.

What strength should a retailer stock first for Vape Sourcing e-liquid?

Start with the middle strength in the range and add one step either side once you see what sells. Shops that open with a single strength almost always have to reorder within a fortnight, and the second order is usually the one that reveals the real demand curve.

How quickly can a repeat order of Vape Sourcing e-liquid be dispatched?

In-stock repeat orders normally leave within 2 working days, and consolidated freight shortens the door-to-door time considerably on larger consignments. Planning the reorder point against the slowest leg rather than the fastest avoids the gaps that cost sales.

How should Vape Sourcing e-liquid be stored to protect shelf life?

Cool, dark and sealed. Heat and direct sunlight degrade both nicotine and flavour well before the printed date, and a shop window is the worst place in the building to keep stock for any length of time.
