RELX Pod Sizes Explained: 0.4 to 4.0 Spec Comparison for Wholesale Buyers

Pod specs are numbered after the format the trade uses, and the number tracks roughly with how much liquid a pod carries. For a distributor the useful question is never which number is best — it is which numbers your installed devices and your channel can absorb. This page puts the whole range in one table and explains what each tier is for.

Liquid volume per pod, across the range

Each row has its own page with the full wholesale terms, MOQ and freight options: see the product line catalog.

Three ways buyers choose lines

1. Installed base first

The 0.4 spec and 0.5 spec sit at the bottom of the range and carry the deepest repeat purchase, because the devices already in customers’ pockets were built around them. Partners entering a market usually anchor here: turnover is predictable and the flavor library is broadest on these generations.

2. The step-up ladder

The 0.6 spec and 0.7 spec give retail a visible middle rung. Customers who find the entry pods too small have somewhere to go without jumping to premium pricing, which is where the 0.9 spec takes over as the shelf’s top step.

3. Capacity as the headline

Above 2 ml the conversation changes from price per pod to sessions per pod. The 2.5, 3.0 and 4.0 lines work in channels where customers replace less often and will pay for it, and they are the specs private-label brands lead with on pack. Where local rules frame capacity around 2 ml, the 2.0 spec is the compliant answer instead.

What the number does not tell you

• Flavor availability differs by generation. The live list for each line comes back with your quote rather than being published as a fixed catalog.
• Compare cost per milliliter, not per pod. A larger pod that costs slightly more often wins at retail on that measure.
• Reorder cadence changes with size. Smaller pods sell through faster per device; larger ones sit longer between purchases, which affects how much stock you tie up.
• Fit is generation-specific. A round-tip device does not take a standard mouthpiece, so that line exists precisely because the shape narrows the market.

How this maps onto an order

Minimums apply per flavor — 100 packs per flavor on standard lines — so five lines with two flavors each is ten minimums, or 1,000 packs. Standard orders dispatch in 5–7 working days, and mixed first orders are common: we would rather help you weight the order toward proven SKUs than see you commit volume to a spec you cannot move.

The MOQ and mixed-order guide walks through structuring that first order, and the authenticity checks are worth running against any supplier before payment, us included.
